00:01:59,760 --> 00:02:01,760
Speaker 1: If that's what you're driving at. No, that's not what

35
00:02:01,800 --> 00:02:05,120
Speaker 1: I was driving at. Uh yeah, no I'm not. Do

36
00:02:05,160 --> 00:02:08,640
Speaker 1: you get fevers a lot? No, not anymore. Although I

37
00:02:08,680 --> 00:02:11,160
Speaker 1: haven't for a long time, like I've never been like

38
00:02:11,160 --> 00:02:15,000
Speaker 1: a fever person. I've probably had like a handful. Maybe.

39
00:02:15,000 --> 00:02:17,440
Speaker 1: How many fevers have you had? Not a ton since

40
00:02:17,440 --> 00:02:19,880
Speaker 1: I was a kid. Yeah, not a lot of adult fevers.

41
00:02:20,400 --> 00:02:26,119
Speaker 1: I mean I've had like, uh, hip hop fever, rock

42
00:02:26,160 --> 00:02:30,040
Speaker 1: and roll fever, yellow fever. I've had the fever for

43
00:02:30,080 --> 00:02:33,040
Speaker 1: a flavor of a pringle. Oh Man, me too. What

44
00:02:33,120 --> 00:02:35,000
Speaker 1: are those? Those aren't even potato chips? Are they? Their

45
00:02:35,040 --> 00:02:39,079
Speaker 1: potato crisps? And those are good. They're mashed together potato parts.

46
00:02:39,160 --> 00:02:41,400
Speaker 1: I don't think I want to know how those are made. No,

47
00:02:41,960 --> 00:02:45,040
Speaker 1: it's like chicken McNuggets. I think a unicorn just poops

48
00:02:45,080 --> 00:02:49,519
Speaker 1: them out. Have you seen unicorn pizza? It's a little much.

49
00:02:50,480 --> 00:02:53,480
Speaker 1: There's a restaurant in New York, I'm not quite sure where,

50
00:02:53,480 --> 00:02:56,720
Speaker 1: maybe lowery Side. They have unicorn pizza. It's like um

51
00:02:57,120 --> 00:03:01,600
Speaker 1: dough okay, good start um, like a nice pestel colored

52
00:03:01,639 --> 00:03:08,680
Speaker 1: frosting instead of sauce. UM, A mound of cotton candy, um,

53
00:03:08,840 --> 00:03:13,160
Speaker 1: nerds or pop rocks maybe um, and then some other stuff.

54
00:03:14,000 --> 00:03:16,840
Speaker 1: Supposedly it tastes kind of good. I'll eat anything that

55
00:03:16,880 --> 00:03:19,480
Speaker 1: has enough frosting on it. I like frosting, but I'm

56
00:03:19,480 --> 00:03:23,200
Speaker 1: not into like sugary candies. Really like nerds. And pop

57
00:03:23,280 --> 00:03:26,200
Speaker 1: rocks and stuff. You know, I did a brain stuff

58
00:03:26,240 --> 00:03:30,520
Speaker 1: once on pop rocks and that was interesting. Yeah. Yeah,

59
00:03:30,600 --> 00:03:33,839
Speaker 1: your tongue actually warms the pop rocks to the point

60
00:03:33,880 --> 00:03:36,400
Speaker 1: where they melt. And since they have C O two

61
00:03:36,680 --> 00:03:39,720
Speaker 1: trapped inside during the manufacturing process, that c O two

62
00:03:39,720 --> 00:03:42,400
Speaker 1: suddenly is released in a pop So it's just a

63
00:03:42,400 --> 00:03:45,560
Speaker 1: little bubble of C two. That's gotta be good for you.

64
00:03:45,840 --> 00:03:52,080
Speaker 1: I'm sure it's funny. My head of roommate in college, like,

65
00:03:52,440 --> 00:03:55,560
Speaker 1: not many adults eat candy, Like people eat chocolate and

66
00:03:55,560 --> 00:03:58,839
Speaker 1: stuff like that, candy bars, but candy candy, I don't

67
00:03:58,880 --> 00:04:02,800
Speaker 1: know when adults is just a little strange. Yeah, do

68
00:04:02,920 --> 00:04:07,760
Speaker 1: be candy? Sure? Like what mentos? Not mint mentos? Like

69
00:04:08,040 --> 00:04:11,680
Speaker 1: candy mentos. I like those. Well. I had a roommate

70
00:04:11,680 --> 00:04:13,920
Speaker 1: that would go to the convenient store next and this

71
00:04:13,960 --> 00:04:17,280
Speaker 1: is college granted, but he still eats the stuff, I think,

72
00:04:17,520 --> 00:04:21,560
Speaker 1: and he would go with like fifteen dollars and buy

73
00:04:22,160 --> 00:04:25,040
Speaker 1: you know, like giant sweet tarts. You know it's big

74
00:04:25,080 --> 00:04:30,560
Speaker 1: chewable ones and like uh, fun dip and nerds and

75
00:04:30,640 --> 00:04:34,800
Speaker 1: just all kinds of candy fun dip, remember liquor made

76
00:04:35,480 --> 00:04:39,520
Speaker 1: there's the same thing I think, Yeah, it's just right,

77
00:04:40,080 --> 00:04:41,800
Speaker 1: Like I don't have a foot, but I've got my

78
00:04:41,920 --> 00:04:46,000
Speaker 1: Lika made. Oh man, can you can you guys out

79
00:04:46,000 --> 00:04:49,800
Speaker 1: there in podcast lantel over stalling because we are big time,

80
00:04:49,839 --> 00:04:54,279
Speaker 1: because we happened upon a topic that no one really

81
00:04:54,360 --> 00:05:00,400
Speaker 1: knows what's what? Yeah, I mean we're talking about fever dreams.

82
00:05:01,560 --> 00:05:04,839
Speaker 1: We know about fevers, yep, kind of know about dreams,

83
00:05:05,920 --> 00:05:10,600
Speaker 1: but apparently no one's really gotten to work on figuring

84
00:05:10,600 --> 00:05:16,000
Speaker 1: out what fever dreams themselves are. So it's largely anecdotal. Yeah,

85
00:05:16,160 --> 00:05:17,840
Speaker 1: so you're gonna have to bear with us something. We'll

86
00:05:17,880 --> 00:05:21,839
Speaker 1: leave it. We'll leave that there for now. But I

87
00:05:21,880 --> 00:05:24,080
Speaker 1: guess a good place to start is by talking about

88
00:05:24,120 --> 00:05:28,120
Speaker 1: both those things separately. Uh, and starting with fevers. You

89
00:05:28,120 --> 00:05:31,520
Speaker 1: know you've always heard ninety eight point six fahrenheit is

90
00:05:31,600 --> 00:05:38,839
Speaker 1: the normal internal body temperature of human um. That in

91
00:05:39,720 --> 00:05:41,440
Speaker 1: that was a big study that that is really ninety

92
00:05:41,480 --> 00:05:45,640
Speaker 1: eight point two what um, depending on like how old

93
00:05:45,720 --> 00:05:47,760
Speaker 1: you are, what time of day it is, what you're

94
00:05:47,800 --> 00:05:50,640
Speaker 1: doing where you If you put it in your butt

95
00:05:50,760 --> 00:05:52,960
Speaker 1: or in your under your armpit, or in your mouth

96
00:05:53,080 --> 00:05:55,080
Speaker 1: or in your ear, or all of them at once,

97
00:05:55,600 --> 00:05:59,040
Speaker 1: that'd be something else. Uh, it can vary a little bit.

98
00:05:59,440 --> 00:06:01,080
Speaker 1: So I think there is a bit of a slight

99
00:06:01,240 --> 00:06:04,320
Speaker 1: sliding scale to that number. Yeah, for sure. But I

100
00:06:04,360 --> 00:06:07,000
Speaker 1: think the key is is it's going to be roughly

101
00:06:07,040 --> 00:06:11,920
Speaker 1: around there. And even if you have an average body

102
00:06:11,960 --> 00:06:15,080
Speaker 1: temperature that's not exactly ninet eight point six, let's say

103
00:06:15,080 --> 00:06:21,359
Speaker 1: you typically tend towards five run cooler. Yeah, your body

104
00:06:21,400 --> 00:06:24,600
Speaker 1: temperatures still during the average day gonna fluctuate plus or

105
00:06:24,640 --> 00:06:28,039
Speaker 1: minus about a degree fair height either way. Yeah, So

106
00:06:28,080 --> 00:06:29,960
Speaker 1: I looked a little bit into the ninety eight point

107
00:06:30,000 --> 00:06:33,040
Speaker 1: six and the original um dude that came up with

108
00:06:33,080 --> 00:06:38,400
Speaker 1: that was a a German physician named Carl Reinholdt August Vondelick.

109
00:06:39,200 --> 00:06:42,799
Speaker 1: That was good, a good one. When eight sixty eight

110
00:06:42,800 --> 00:06:45,479
Speaker 1: he wrote a book, Well he did his studies where

111
00:06:45,480 --> 00:06:47,800
Speaker 1: he had this temperature rod he would stick under the

112
00:06:47,880 --> 00:06:49,760
Speaker 1: armpits of all these people. He's like, where do you

113
00:06:49,760 --> 00:06:53,440
Speaker 1: want that exactly? And everyone went said, everyone always says,

114
00:06:56,560 --> 00:07:02,000
Speaker 1: you know the comedian Rory Scoville, No, he should just

115
00:07:02,080 --> 00:07:05,440
Speaker 1: check him out. He does these weird things, like he'll

116
00:07:05,520 --> 00:07:08,760
Speaker 1: just do his whole routine with the German accent, like

117
00:07:08,800 --> 00:07:11,120
Speaker 1: for no reason, whatsoever. I like the sound of that.

118
00:07:11,200 --> 00:07:16,280
Speaker 1: And he did one about stealing old people, like kidnapping

119
00:07:16,320 --> 00:07:20,280
Speaker 1: old people. For the German accent. He's from South Carolina,

120
00:07:20,320 --> 00:07:23,560
Speaker 1: I think, but he's done shows with like a severe

121
00:07:23,680 --> 00:07:26,760
Speaker 1: Southern accent and one just normal accent, and he'll do

122
00:07:26,800 --> 00:07:29,200
Speaker 1: a German thing. He just like people, I guess. So

123
00:07:29,320 --> 00:07:34,360
Speaker 1: he's great. He's one of my favorites. So anyway, UM

124
00:07:35,000 --> 00:07:38,160
Speaker 1: sixty eight he wrote a book called after these experiments,

125
00:07:38,200 --> 00:07:46,080
Speaker 1: called doshen Elkin Pharma and kind can Heighten. And I

126
00:07:46,160 --> 00:07:48,480
Speaker 1: looked at It's funny. The real translation I think of

127
00:07:48,520 --> 00:07:51,480
Speaker 1: that is on the temperature in diseases, but if you

128
00:07:51,600 --> 00:07:55,360
Speaker 1: type in Google Translate, it comes out as the behavior

129
00:07:55,520 --> 00:08:03,800
Speaker 1: of the intrinsically warm in sick units. That's the subtitle. Yeah,

130
00:08:03,840 --> 00:08:05,440
Speaker 1: So anyway, he's a guy that came up with ninety

131
00:08:05,440 --> 00:08:07,520
Speaker 1: eight point six and that stood for a long time.

132
00:08:07,680 --> 00:08:11,760
Speaker 1: But that's just so that was just based on his observations,

133
00:08:11,840 --> 00:08:14,560
Speaker 1: his study, and it's stuck. It was an average. It

134
00:08:14,680 --> 00:08:16,480
Speaker 1: wasn't like this is what you should be. It was

135
00:08:16,520 --> 00:08:19,640
Speaker 1: just the average of all these people. And then hundred

136
00:08:20,520 --> 00:08:24,239
Speaker 1: thirty years later we finally got around to verifying whether

137
00:08:24,400 --> 00:08:26,080
Speaker 1: that was actually true or not. Well, I mean it

138
00:08:26,080 --> 00:08:28,400
Speaker 1: says a ninety two that they said it was ninety

139
00:08:28,440 --> 00:08:30,640
Speaker 1: eight point two from another study, but then everything I

140
00:08:30,680 --> 00:08:33,920
Speaker 1: still read says point six. So all right, well, I

141
00:08:34,000 --> 00:08:35,720
Speaker 1: know what you're talking about, though I had heard in

142
00:08:35,760 --> 00:08:38,280
Speaker 1: the last few years that they're like that point six

143
00:08:38,360 --> 00:08:42,160
Speaker 1: jazz is kind of kind of made upright, So, um,

144
00:08:42,320 --> 00:08:44,440
Speaker 1: the point is is that your body is going to

145
00:08:44,480 --> 00:08:48,000
Speaker 1: be roughly somewhere around there, right, that's your normal body temperature,

146
00:08:48,440 --> 00:08:51,640
Speaker 1: and then depending on the time of day, it's either

147
00:08:51,640 --> 00:08:53,200
Speaker 1: going to be a little cooler in that or a

148
00:08:53,200 --> 00:08:57,360
Speaker 1: little warmer than that. And our body temperatures are regulated

149
00:08:57,400 --> 00:09:00,880
Speaker 1: by something called the hypothalamus. And like I said, depending

150
00:09:00,920 --> 00:09:03,160
Speaker 1: on the time of day, your body temperature is gonna fluctuate,

151
00:09:03,559 --> 00:09:07,360
Speaker 1: and that's tied to sleep apparently, so as your body

152
00:09:07,360 --> 00:09:10,439
Speaker 1: temperature is rising, usually in the late afternoon, is about

153
00:09:10,480 --> 00:09:14,199
Speaker 1: where it peaks during the day. That's associated with wakefulness

154
00:09:14,200 --> 00:09:18,240
Speaker 1: alertness not necessarily just having a high body temperature, but

155
00:09:18,840 --> 00:09:23,520
Speaker 1: an incline in the temperature in your body means you're awake,

156
00:09:23,559 --> 00:09:26,800
Speaker 1: you're alert, you're ready to go right, ready for action.

157
00:09:27,360 --> 00:09:31,920
Speaker 1: If once it starts to decline, that's associated with drowsiness,

158
00:09:32,040 --> 00:09:37,320
Speaker 1: and it hits it's um, it's trough. Your body temperature

159
00:09:37,320 --> 00:09:40,199
Speaker 1: is at its lowest right about before you wake up,

160
00:09:41,040 --> 00:09:44,160
Speaker 1: and that's actually associated with R E. M. Sleep. So

161
00:09:44,200 --> 00:09:46,200
Speaker 1: there are some some stuff starting to come out. Just

162
00:09:46,400 --> 00:09:49,800
Speaker 1: bear with us, everybody. We're laying the groundwork. So your

163
00:09:49,800 --> 00:09:53,760
Speaker 1: body temperature changes, the hypothalamus is directing the whole thing,

164
00:09:54,120 --> 00:09:59,640
Speaker 1: and sleep and wakefulness has something to do. It's related

165
00:09:59,640 --> 00:10:03,680
Speaker 1: to your body temperature changes. All right, good night, you

166
00:10:03,760 --> 00:10:05,520
Speaker 1: take it from here. Well, you know what, let's take

167
00:10:05,520 --> 00:10:08,040
Speaker 1: a break because I'm not sure where I should go.

168
00:10:09,000 --> 00:10:33,880
Speaker 1: We'll be right back. Okay, I was being coy, you

169
00:10:33,960 --> 00:10:39,160
Speaker 1: said stage very nicely. Okay. Uh So, if your body

170
00:10:40,200 --> 00:10:44,680
Speaker 1: gets let's say, some bad bacteria gets in it, and

171
00:10:44,840 --> 00:10:50,320
Speaker 1: your body is alerted warning intruder is coming, your immune

172
00:10:50,320 --> 00:10:56,239
Speaker 1: system kicks into gear and it starts producing this biochemical

173
00:10:56,320 --> 00:11:01,439
Speaker 1: material called a pyrogeny. This is my new favorite thing

174
00:11:01,480 --> 00:11:05,800
Speaker 1: the body does. Yeah, well you knew that before, right

175
00:11:05,920 --> 00:11:07,839
Speaker 1: or did you just not know the mechanism. I mean,

176
00:11:07,880 --> 00:11:10,240
Speaker 1: I knew humans get fevers, and I knew the fever

177
00:11:10,400 --> 00:11:12,800
Speaker 1: was to kind of like cook out everything. I didn't

178
00:11:12,840 --> 00:11:16,800
Speaker 1: understand the mechanism. I understand answer your question, then, oh yeah,

179
00:11:16,880 --> 00:11:23,240
Speaker 1: can I So these pyrogen's, right, they are um these

180
00:11:23,280 --> 00:11:26,640
Speaker 1: biochemical markers that are released by the immune system in

181
00:11:26,679 --> 00:11:29,240
Speaker 1: the body or and this is why I love this.

182
00:11:29,600 --> 00:11:33,520
Speaker 1: There's some bacterias, some pathogens that make humans sick that

183
00:11:33,600 --> 00:11:37,840
Speaker 1: produce pyrogen's naturally. So when they show up, they just

184
00:11:37,880 --> 00:11:42,040
Speaker 1: start releasing them, and they just give themselves away. It's

185
00:11:42,200 --> 00:11:45,080
Speaker 1: they're big dummies in that way. They're like, hey, where's

186
00:11:45,120 --> 00:11:47,800
Speaker 1: the party. They kick open the door. They're carrying like

187
00:11:47,840 --> 00:11:51,120
Speaker 1: a pony keg under one arm, their guts sticking out.

188
00:11:51,240 --> 00:11:54,440
Speaker 1: It's just that that's that's like that kind of bacteria, right.

189
00:11:54,800 --> 00:11:57,400
Speaker 1: So the pyrogans enter the bloodstream and they travel to

190
00:11:57,400 --> 00:12:02,240
Speaker 1: the hypothalamus because remember the hypothal mis controls your um

191
00:12:02,320 --> 00:12:05,080
Speaker 1: your body temperature, and this is what they do, Chuck,

192
00:12:05,120 --> 00:12:09,240
Speaker 1: are you ready for what the pyrogens do. They go

193
00:12:09,320 --> 00:12:15,200
Speaker 1: to your hypothalamus and they dampen the heat sensing neurons

194
00:12:15,200 --> 00:12:19,480
Speaker 1: and the hypothalamus, and they excite the cold sensing neurons

195
00:12:19,480 --> 00:12:22,520
Speaker 1: and your hypothalamus, and they trick your hypothalamus in the

196
00:12:22,640 --> 00:12:26,000
Speaker 1: thinking your body is suddenly gotten very very cold, so

197
00:12:26,040 --> 00:12:29,560
Speaker 1: that your hypothalamus turns the temperature up and says, don't

198
00:12:29,600 --> 00:12:31,800
Speaker 1: let any of this heat out. We gotta we gotta

199
00:12:31,840 --> 00:12:34,880
Speaker 1: warm back up. It tricks your body and your hypothalamus

200
00:12:34,920 --> 00:12:37,760
Speaker 1: and creating a fever. That's right. And they do this

201
00:12:38,000 --> 00:12:41,160
Speaker 1: because well they don't do this because but what happens

202
00:12:41,200 --> 00:12:44,240
Speaker 1: from there. They do this because they're dumb. But what

203
00:12:44,280 --> 00:12:46,640
Speaker 1: happens from there is, like you said, the fever, what

204
00:12:46,720 --> 00:12:49,760
Speaker 1: a fever is, and why you want that fever for

205
00:12:49,800 --> 00:12:52,640
Speaker 1: at least a little while that it does. It's it's

206
00:12:52,679 --> 00:12:57,199
Speaker 1: trying to cook and burn and bake that bacteria until

207
00:12:57,240 --> 00:13:01,280
Speaker 1: it dies. It is your body's fighting. Like when you hear,

208
00:13:01,400 --> 00:13:04,600
Speaker 1: you know, like your fever broke, that's usually a good sign.

209
00:13:04,760 --> 00:13:07,240
Speaker 1: That means yeah, right, that your fever did its job

210
00:13:07,840 --> 00:13:10,560
Speaker 1: and it's cooked all that bacteria up and you're going

211
00:13:10,600 --> 00:13:14,240
Speaker 1: to be on the men soon. Uh So basically that's

212
00:13:14,240 --> 00:13:16,480
Speaker 1: what's happening. And this is the great thing about a fever.

213
00:13:16,600 --> 00:13:20,000
Speaker 1: But um, you know, fever makes you feel like crap

214
00:13:20,080 --> 00:13:23,160
Speaker 1: because it's a lot of hard work to kill all

215
00:13:23,160 --> 00:13:25,280
Speaker 1: those things. Well it is, there's a lot of um.

216
00:13:25,800 --> 00:13:29,000
Speaker 1: Your sympathetic nervous system is kicked into high gear, which

217
00:13:29,040 --> 00:13:31,040
Speaker 1: I found out is one reason why they say you

218
00:13:31,040 --> 00:13:35,120
Speaker 1: want to feed a cold starve a fever because you

219
00:13:35,120 --> 00:13:38,760
Speaker 1: don't want to introduce digestion because it requires the parasympathetic

220
00:13:38,800 --> 00:13:42,280
Speaker 1: nervous system, right fight or flight, and you don't want

221
00:13:42,280 --> 00:13:44,360
Speaker 1: those two things going on while your body has a fever.

222
00:13:44,640 --> 00:13:46,600
Speaker 1: It's just a lot of extra work for it, right,

223
00:13:47,080 --> 00:13:49,480
Speaker 1: But one of the one of the things that is

224
00:13:49,520 --> 00:13:52,320
Speaker 1: going on when your body has a fever, when that

225
00:13:52,400 --> 00:13:56,600
Speaker 1: temperature rises, it's hard enough on your organs, but it's

226
00:13:56,640 --> 00:13:59,360
Speaker 1: also hard on the level just the fact that they're

227
00:13:59,440 --> 00:14:03,280
Speaker 1: operating outside of their normal operating temperature, and that makes

228
00:14:03,280 --> 00:14:05,880
Speaker 1: it very hard on them and can actually cook some

229
00:14:05,920 --> 00:14:08,920
Speaker 1: of the ingredients inside yourselves. Yeah, I mean, it's like

230
00:14:08,960 --> 00:14:11,400
Speaker 1: working in a too hot of an environment. It's just

231
00:14:11,440 --> 00:14:14,200
Speaker 1: it's never fun for anyone. Although we've got some people

232
00:14:14,280 --> 00:14:17,839
Speaker 1: love that stuff, yeah, but they're still they might like it,

233
00:14:17,960 --> 00:14:21,960
Speaker 1: but they still aren't working fast. They might be happy,

234
00:14:22,040 --> 00:14:25,080
Speaker 1: but they're slow. So if you have a fever, what's

235
00:14:25,080 --> 00:14:30,160
Speaker 1: considered a fever now, if you're an adult and your

236
00:14:30,280 --> 00:14:33,800
Speaker 1: oral temperature is above one point four or if your

237
00:14:33,840 --> 00:14:37,720
Speaker 1: rectal or ear temperatures above one oh one then that's

238
00:14:37,720 --> 00:14:42,280
Speaker 1: considered a fever. If you're a kid, um, good luck

239
00:14:42,320 --> 00:14:45,520
Speaker 1: getting anything besides the rectal temperature, because it's just tough.

240
00:14:46,000 --> 00:14:49,920
Speaker 1: You have basically no right well ye which you have

241
00:14:49,960 --> 00:14:53,160
Speaker 1: as wiggly kids who aren't like, sure, stick something in

242
00:14:53,200 --> 00:14:57,840
Speaker 1: my ear for four seconds, but up the up the kazoo.

243
00:14:57,960 --> 00:15:00,760
Speaker 1: There's not really anything you can do about that. All

244
00:15:00,800 --> 00:15:05,440
Speaker 1: they can do is say, yeah, exactly. So the rectal

245
00:15:05,480 --> 00:15:10,120
Speaker 1: temperature for a kid above one point four and um.

246
00:15:10,200 --> 00:15:13,600
Speaker 1: With adults like you don't have to really worry about

247
00:15:13,640 --> 00:15:15,680
Speaker 1: your fever too much. If it if it tops a

248
00:15:15,760 --> 00:15:19,200
Speaker 1: hundred and five for you know, any period of time,

249
00:15:19,640 --> 00:15:21,880
Speaker 1: you probably want to do something about that. That's what

250
00:15:21,960 --> 00:15:24,600
Speaker 1: I saw was the hundred and five degree hype mark

251
00:15:24,760 --> 00:15:26,960
Speaker 1: was about where you should start to worry. Yeah, as

252
00:15:26,960 --> 00:15:29,280
Speaker 1: an adult, and you're gonna feel so awful. If your

253
00:15:29,320 --> 00:15:32,400
Speaker 1: temperature is one oh five, you're you've probably already been

254
00:15:32,440 --> 00:15:35,800
Speaker 1: to a doctor at that points. For kids, it's different though.

255
00:15:36,160 --> 00:15:38,600
Speaker 1: If you don't want to let your child get up

256
00:15:38,640 --> 00:15:40,720
Speaker 1: to one oh five, that's bad, bad, bad. So what

257
00:15:40,880 --> 00:15:42,720
Speaker 1: is it for kids that you really want to start worrying?

258
00:15:42,800 --> 00:15:46,520
Speaker 1: But did you say, you know what I'm not exactly sure.

259
00:15:46,560 --> 00:15:48,920
Speaker 1: I mean, it probably depends on whether you're a first

260
00:15:48,920 --> 00:15:52,280
Speaker 1: time pairent or this is your second kid. Well, and

261
00:15:52,400 --> 00:15:54,920
Speaker 1: it varies with the age, you know, it's like zero

262
00:15:54,920 --> 00:15:57,520
Speaker 1: to eighteen months. It's something, and like what you should

263
00:15:57,520 --> 00:16:02,120
Speaker 1: do is consult that your doctor. Yeah exactly. But you know,

264
00:16:02,200 --> 00:16:04,640
Speaker 1: any kind of temperature you should for a child, you

265
00:16:04,640 --> 00:16:07,320
Speaker 1: should kind of be a little more alert about, right.

266
00:16:07,520 --> 00:16:09,600
Speaker 1: But we're not in medical experts here, no, we're not.

267
00:16:09,640 --> 00:16:12,280
Speaker 1: And everything we're saying assumes that you have healthcare coverage.

268
00:16:12,920 --> 00:16:18,000
Speaker 1: That's right. Um, all right, so that's fever in general.

269
00:16:18,120 --> 00:16:20,960
Speaker 1: You got anything else on that? Yeah? One other thing? Um?

270
00:16:21,600 --> 00:16:28,000
Speaker 1: Uh the pyrogens um Piro. By the way, it's a mistake, man,

271
00:16:28,040 --> 00:16:30,840
Speaker 1: I did have some coincidence. No, it's not. What is

272
00:16:30,880 --> 00:16:34,480
Speaker 1: the Latin for fire, Greek word for fire? Yeah, Piro

273
00:16:35,280 --> 00:16:40,280
Speaker 1: def Leppard, right, Um, a great song. It really is

274
00:16:40,720 --> 00:16:44,360
Speaker 1: the whole album. Yeah. They just mentioned it in Rock

275
00:16:44,400 --> 00:16:48,400
Speaker 1: of Ages that comes up. They should have a song

276
00:16:48,440 --> 00:16:52,160
Speaker 1: called Pyromania wonderful. But that's pretty cool. It's like the

277
00:16:52,200 --> 00:16:57,440
Speaker 1: antithesis of your band, your album, and your song all

278
00:16:57,480 --> 00:17:01,040
Speaker 1: being the same name, like Big Country. Oh I love

279
00:17:01,080 --> 00:17:05,920
Speaker 1: that song. Sure, But it's pretty uncreative, but you're basically saying, like,

280
00:17:06,240 --> 00:17:08,359
Speaker 1: here's our basket and we're gonna play every egg we

281
00:17:08,400 --> 00:17:11,680
Speaker 1: have into it. That's the one one thing we came

282
00:17:11,760 --> 00:17:14,560
Speaker 1: up with. I saw David Spade bit once and he

283
00:17:14,920 --> 00:17:17,280
Speaker 1: was talking about he was complaining it wasn't even comedy.

284
00:17:17,320 --> 00:17:18,920
Speaker 1: He's just complaining that he went and saw a big

285
00:17:18,960 --> 00:17:22,440
Speaker 1: country and they didn't play the song Big Count. Yeah.

286
00:17:23,040 --> 00:17:25,520
Speaker 1: He's like, it's the name of your band. It's the

287
00:17:25,640 --> 00:17:30,560
Speaker 1: one song everybody came to see and play it. He's well,

288
00:17:30,920 --> 00:17:33,000
Speaker 1: the longest, the long and short of it is I

289
00:17:33,040 --> 00:17:34,920
Speaker 1: totally forgot what the other thing I had to say

290
00:17:34,920 --> 00:17:38,160
Speaker 1: about Pyritans was, so I'll probably think of it. Oh,

291
00:17:38,200 --> 00:17:42,919
Speaker 1: I know what it was, Pyrogen's um. As your immune

292
00:17:42,960 --> 00:17:45,600
Speaker 1: system grows in ages and you become a grown up,

293
00:17:45,920 --> 00:17:48,920
Speaker 1: the pyrigans have a little less of an effect on you.

294
00:17:49,119 --> 00:17:51,119
Speaker 1: So where if you're a kid and your immune system

295
00:17:51,160 --> 00:17:54,240
Speaker 1: is young and inexperienced, your fever is gonna shoot up

296
00:17:54,320 --> 00:17:58,200
Speaker 1: quick and it's going to it's gonna get hotter faster.

297
00:17:58,840 --> 00:18:00,399
Speaker 1: So you do want to stay on top of a

298
00:18:00,440 --> 00:18:02,960
Speaker 1: kid's fever because their immune system is not used to

299
00:18:03,119 --> 00:18:06,200
Speaker 1: pyrogens coming and messing with their hypothalamus like an adults.

300
00:18:06,280 --> 00:18:08,480
Speaker 1: It is. Yeah, it'll spike much faster at this good point.

301
00:18:08,560 --> 00:18:10,880
Speaker 1: That's what I was trying to think of. Yeah, that's true.

302
00:18:10,920 --> 00:18:15,200
Speaker 1: You need to take that need take that rectal temperature

303
00:18:16,119 --> 00:18:18,520
Speaker 1: way more than you're comfortable with. I don't recall that

304
00:18:18,640 --> 00:18:21,560
Speaker 1: ever having been done to me. Well, because you don't

305
00:18:21,560 --> 00:18:25,520
Speaker 1: remember being a baby. No, but my parents were pretty strict,

306
00:18:26,880 --> 00:18:29,600
Speaker 1: pretty stern. Mean, by the time a kid is old

307
00:18:29,680 --> 00:18:32,320
Speaker 1: enough to where you can say, like, hey, put this

308
00:18:32,359 --> 00:18:34,360
Speaker 1: under your tongue, or hold still for a minute while

309
00:18:34,359 --> 00:18:37,280
Speaker 1: I put this in your ear, but pre that when

310
00:18:37,320 --> 00:18:41,200
Speaker 1: they're not sentient humans and they're just you know, crying,

311
00:18:41,200 --> 00:18:44,359
Speaker 1: whiny little sacks of flesh, you gotta stick it right

312
00:18:44,440 --> 00:18:48,960
Speaker 1: up the butt. Okay, Harry's laughing. She almost spit out

313
00:18:48,960 --> 00:18:51,600
Speaker 1: her schwarm a salad. Harry's done plenty of that, so

314
00:18:51,720 --> 00:18:58,240
Speaker 1: she knows. Okay, So into dreams, um, I always think

315
00:18:58,240 --> 00:19:01,320
Speaker 1: we've done a general show on dreams. I think we did. Finally,

316
00:19:01,760 --> 00:19:06,040
Speaker 1: I didn't find it. What still, No, it's a lucid dreaming.

317
00:19:06,240 --> 00:19:08,879
Speaker 1: Can you control your dreams? That's the same thing, wasn't it.

318
00:19:11,000 --> 00:19:14,040
Speaker 1: I think that maybe because no, we we did one

319
00:19:14,080 --> 00:19:18,160
Speaker 1: on dreams. I didn't see it. Wow, I can't believe it.

320
00:19:18,920 --> 00:19:23,760
Speaker 1: I can't believe it. Well, this contributes to the little

321
00:19:23,760 --> 00:19:27,240
Speaker 1: by little, someone will know. Jill Hurley, where are you

322
00:19:27,320 --> 00:19:30,480
Speaker 1: when we need you? Our statistician, a minister of stats?

323
00:19:31,480 --> 00:19:33,280
Speaker 1: All right, well we'll talk about dreams a bit here then,

324
00:19:33,320 --> 00:19:35,720
Speaker 1: Even though we've explained this in various episodes here and

325
00:19:35,760 --> 00:19:39,760
Speaker 1: there to some degree, but uh dreams. You know, if

326
00:19:39,800 --> 00:19:45,600
Speaker 1: you're psychologist, you you really love to spend time talking

327
00:19:45,640 --> 00:19:51,360
Speaker 1: and dissecting dreams, interpreting dreams. If you're a um more

328
00:19:51,359 --> 00:19:54,879
Speaker 1: into the neurology side of science, you don't really care

329
00:19:54,920 --> 00:19:57,920
Speaker 1: about that kind of stuff. Um. In fact, for many

330
00:19:58,000 --> 00:20:02,560
Speaker 1: years they thought it was called activation synthesis hypothesis, which

331
00:20:02,680 --> 00:20:07,000
Speaker 1: was you go to sleep and all these uh synapsters

332
00:20:07,000 --> 00:20:10,760
Speaker 1: are just randomly firing and they don't really add up

333
00:20:10,760 --> 00:20:13,280
Speaker 1: to even a story. You just do that when you

334
00:20:13,320 --> 00:20:16,400
Speaker 1: wake up because you're human. Yeah, but that I mean,

335
00:20:16,440 --> 00:20:19,359
Speaker 1: that's complete. Bs. Well, you almost get the impression that

336
00:20:19,400 --> 00:20:22,199
Speaker 1: they came up with this, and the neurologists came up

337
00:20:22,240 --> 00:20:25,119
Speaker 1: with it to stick out their territory in response to

338
00:20:25,320 --> 00:20:29,359
Speaker 1: years of psychoanalysts saying, this is what dreams are like,

339
00:20:29,720 --> 00:20:34,639
Speaker 1: tapping into the collective unconscious or um, they're you're repressed memories.

340
00:20:35,240 --> 00:20:40,520
Speaker 1: Neuroscience said, no, nothing, they're just your stupid, wet brain

341
00:20:40,640 --> 00:20:43,679
Speaker 1: going crazy while you sleep. Yeah, which we all know

342
00:20:43,760 --> 00:20:46,600
Speaker 1: now is not true. I saw another one too. What's

343
00:20:46,640 --> 00:20:51,000
Speaker 1: that um threat simulation theory? Have you heard of that one? No,

344
00:20:51,240 --> 00:20:54,560
Speaker 1: but that's a great band name. Basically, it's you're training

345
00:20:54,560 --> 00:20:57,160
Speaker 1: to be a ninja while you sleep, Like your brain

346
00:20:57,280 --> 00:21:02,600
Speaker 1: is running threat simulations constantly, so that it's like working

347
00:21:02,680 --> 00:21:05,399
Speaker 1: itself out, like getting more and more agile and quick

348
00:21:05,440 --> 00:21:07,920
Speaker 1: and like, like, so you can get better at running

349
00:21:07,960 --> 00:21:11,480
Speaker 1: from a savor tooth tiger if you actually encounter it.

350
00:21:12,080 --> 00:21:15,000
Speaker 1: I can see that early on maybe, and there is

351
00:21:15,000 --> 00:21:18,880
Speaker 1: an evolutionary advantage to it, so evolutionarily speaking, it would

352
00:21:18,960 --> 00:21:23,120
Speaker 1: make sense. The point is it that one came along?

353
00:21:23,160 --> 00:21:26,280
Speaker 1: I was like, no, there's obviously some reason for dreams.

354
00:21:26,320 --> 00:21:29,680
Speaker 1: It's not just random yet. Well, and then maybe I

355
00:21:29,720 --> 00:21:32,000
Speaker 1: could have seen that early on. But then at some

356
00:21:32,080 --> 00:21:34,520
Speaker 1: point someone around the fire had a dream about Tuktok's

357
00:21:34,560 --> 00:21:37,520
Speaker 1: wife and woke up and went, whoa, there was no

358
00:21:37,560 --> 00:21:43,560
Speaker 1: savor tooth tiger and that I'm not sure what that meant, uh,

359
00:21:43,600 --> 00:21:46,040
Speaker 1: but I better not tell tuktok, right, you know. And

360
00:21:46,080 --> 00:21:49,680
Speaker 1: then they went, what's a rectal themome hasn't even been

361
00:21:49,680 --> 00:21:55,520
Speaker 1: invented yet, so uh. These days they've done actual studies, um,

362
00:21:55,600 --> 00:22:00,000
Speaker 1: with E e. G. Machines and MRI machines, and especially

363
00:22:00,080 --> 00:22:04,080
Speaker 1: in Italy, these Italian researchers basically put people to sleep,

364
00:22:04,320 --> 00:22:07,280
Speaker 1: not put them to sleep and the sleeper hole. They

365
00:22:07,359 --> 00:22:10,400
Speaker 1: lay them down in a nice Italian bed, feed them

366
00:22:10,400 --> 00:22:14,199
Speaker 1: some postaphazul, and get out the rectal thermometer and they

367
00:22:14,240 --> 00:22:17,320
Speaker 1: hook him up to all these wires and machines. And

368
00:22:17,359 --> 00:22:19,320
Speaker 1: then they will wake them up at different points in

369
00:22:19,320 --> 00:22:22,520
Speaker 1: the night and say, hey, what were you dreaming of? Um,

370
00:22:22,640 --> 00:22:24,960
Speaker 1: we'd like to talk about it and study what was

371
00:22:25,000 --> 00:22:28,960
Speaker 1: going on with these machines. And um. They actually what

372
00:22:29,040 --> 00:22:33,680
Speaker 1: they found supports the current the prevailing theory. I don't

373
00:22:33,680 --> 00:22:35,200
Speaker 1: think it was their theory. I think it was around,

374
00:22:35,200 --> 00:22:39,840
Speaker 1: but their research supports it called affect regulation theory, which

375
00:22:39,920 --> 00:22:45,040
Speaker 1: is basically that we control our emotions or we process

376
00:22:45,080 --> 00:22:49,240
Speaker 1: our emotions through our dreams. And these Italians found support

377
00:22:49,320 --> 00:22:52,000
Speaker 1: for this and that when they woke people up and

378
00:22:52,040 --> 00:22:55,040
Speaker 1: asked them what they were dreaming about. The ones who

379
00:22:55,080 --> 00:22:57,320
Speaker 1: had the best recall were the ones who had the

380
00:22:57,359 --> 00:23:01,200
Speaker 1: most Theta waves in their frontal lobes, which are slow

381
00:23:01,240 --> 00:23:03,760
Speaker 1: moving waves. Right. Yes, And when you look at an

382
00:23:03,760 --> 00:23:07,920
Speaker 1: e G machine, if you looked at those dreamers brain waves,

383
00:23:08,640 --> 00:23:11,480
Speaker 1: it looked like the brain waves of somebody who was

384
00:23:11,520 --> 00:23:16,040
Speaker 1: sitting there forming and recalling memories. So these people said,

385
00:23:16,400 --> 00:23:18,680
Speaker 1: that's what they're doing. That's what all of us are doing.

386
00:23:18,720 --> 00:23:22,399
Speaker 1: While we're dreaming. We're forming memories. We're taking emotions that

387
00:23:22,440 --> 00:23:26,320
Speaker 1: we've experienced through the day and we're creating memories out

388
00:23:26,320 --> 00:23:29,440
Speaker 1: of them so we can file them away. So we're

389
00:23:29,480 --> 00:23:32,639
Speaker 1: processing our emotions and our dreams. That's the point of dreams.

390
00:23:32,680 --> 00:23:36,360
Speaker 1: That's the current understanding. Yeah, and then I mean other

391
00:23:36,400 --> 00:23:38,240
Speaker 1: parts of the brain that have been active all sort

392
00:23:38,280 --> 00:23:41,720
Speaker 1: of deal with emotion, whether it's the a magdala and

393
00:23:41,760 --> 00:23:45,359
Speaker 1: the hippocampus or the lingual gyrus, which I think we

394
00:23:45,480 --> 00:23:48,560
Speaker 1: just talked about that in another episode. I don't recall.

395
00:23:48,800 --> 00:23:51,960
Speaker 1: I can't remember, um, but they're all areas of the

396
00:23:51,960 --> 00:23:55,280
Speaker 1: brain that relate to emotion and memory, and some with

397
00:23:55,400 --> 00:23:58,879
Speaker 1: visual activity. And you know that kind of makes sense.

398
00:23:58,920 --> 00:24:01,359
Speaker 1: I like that theory and then under that current theory,

399
00:24:01,359 --> 00:24:04,640
Speaker 1: so that's like the the explanation for regular dreams. And

400
00:24:04,680 --> 00:24:07,520
Speaker 1: you can't just have a theory for dreams without including

401
00:24:07,720 --> 00:24:10,560
Speaker 1: nightmares or else your theory is broken. Right, So the

402
00:24:10,720 --> 00:24:17,400
Speaker 1: affect regulation theory considers nightmares. Um, basically, it's an emotion

403
00:24:17,440 --> 00:24:20,040
Speaker 1: that's being put into the process of being, of creating

404
00:24:20,080 --> 00:24:23,480
Speaker 1: a memory, a false memory, right, a dream memory, I

405
00:24:23,560 --> 00:24:26,080
Speaker 1: guess you put it. But it's a real emotion, right,

406
00:24:26,440 --> 00:24:31,240
Speaker 1: and um, it's so big it breaks the process. And

407
00:24:31,280 --> 00:24:33,880
Speaker 1: all of a sudden, this process of creating a fake

408
00:24:33,920 --> 00:24:37,600
Speaker 1: memory of fake experience, UM, goes haywire. And now all

409
00:24:37,600 --> 00:24:42,600
Speaker 1: of a sudden you're enduring some terrible, horrifying experience because

410
00:24:42,640 --> 00:24:45,119
Speaker 1: the emotion that was being processed was too big and

411
00:24:45,119 --> 00:24:47,600
Speaker 1: got out of control. And now you have a nightmare

412
00:24:47,920 --> 00:24:51,199
Speaker 1: t s for you. Yeah, I think we did one

413
00:24:51,200 --> 00:24:56,240
Speaker 1: of night terrors. We did for sure, and sleep paralysis.

414
00:24:57,800 --> 00:25:00,000
Speaker 1: We've covered it all. I think I guess we were.

415
00:25:00,040 --> 00:25:02,240
Speaker 1: They haven't done a dreams one, all right, So let's

416
00:25:02,240 --> 00:25:04,280
Speaker 1: take another break. We're gonna come back and finally talk

417
00:25:04,320 --> 00:25:29,960
Speaker 1: about fever dreams. You robbed me of a Saturday night

418
00:25:30,000 --> 00:25:32,720
Speaker 1: fever reference. I just want to go on record this

419
00:25:32,840 --> 00:25:37,320
Speaker 1: thing that I was wrong, So Chuck, here's where everything

420
00:25:37,400 --> 00:25:41,240
Speaker 1: just kind of goes totally off the rail. We've talked

421
00:25:41,240 --> 00:25:46,639
Speaker 1: about fevers, We've talked about nightmares. The problem is really

422
00:25:47,200 --> 00:25:54,280
Speaker 1: understanding both doesn't necessarily amount to understanding them together. Right, So,

423
00:25:54,440 --> 00:25:56,800
Speaker 1: knowing what fevers are, knowing what dreams are, it doesn't

424
00:25:56,840 --> 00:26:00,720
Speaker 1: mean you know what fever dreams are. But you can

425
00:26:00,720 --> 00:26:03,040
Speaker 1: make stuff up if you want. Yeah, and I don't.

426
00:26:03,040 --> 00:26:05,439
Speaker 1: I'm boy, I don't even think we even said if

427
00:26:05,480 --> 00:26:07,159
Speaker 1: you've never had a fever dream, you might even know

428
00:26:07,200 --> 00:26:09,560
Speaker 1: we're talking about. Feel kind of dumb at this point

429
00:26:09,600 --> 00:26:14,359
Speaker 1: in the podcast. But a fever dream is um, basically

430
00:26:14,480 --> 00:26:18,560
Speaker 1: a nightmare on steroids. It's just so vivid and so

431
00:26:18,680 --> 00:26:23,520
Speaker 1: real and scary. Um that happens, you know, when you

432
00:26:23,560 --> 00:26:28,119
Speaker 1: are sick with a fever. Yes, obviously, so their fever dreams, right,

433
00:26:28,160 --> 00:26:31,440
Speaker 1: so they are a thing. Yeah, but the scientific literature

434
00:26:31,520 --> 00:26:35,199
Speaker 1: on them is super thin, non existent. Kids seemed to

435
00:26:35,200 --> 00:26:38,240
Speaker 1: get them, if not more, at least they stand out

436
00:26:38,240 --> 00:26:42,040
Speaker 1: more to children, and so anecdotally people seem to recall

437
00:26:42,119 --> 00:26:44,720
Speaker 1: having fever dreams. More when they were kids. Whether or

438
00:26:44,720 --> 00:26:48,000
Speaker 1: not that's true or just a memory is uh or

439
00:26:48,040 --> 00:26:50,359
Speaker 1: you know what do you call it, like a memory

440
00:26:50,359 --> 00:26:55,560
Speaker 1: bias or whatever, There's no one really knows. Yeah, well

441
00:26:55,560 --> 00:26:58,480
Speaker 1: that yeah, I mean, we don't really know because I

442
00:26:58,480 --> 00:27:01,199
Speaker 1: don't remember the last time I had a fever and

443
00:27:01,240 --> 00:27:03,000
Speaker 1: if I did, whether or not I had had a

444
00:27:03,040 --> 00:27:06,919
Speaker 1: fever dream. I I don't think I've ever had a

445
00:27:06,920 --> 00:27:08,679
Speaker 1: fever dream. I did when I was a kid. I

446
00:27:08,720 --> 00:27:11,520
Speaker 1: don't remember having fever dreams. I remember being sick as

447
00:27:11,560 --> 00:27:14,600
Speaker 1: a kid and having like nightmares when I was sick,

448
00:27:14,960 --> 00:27:19,560
Speaker 1: so like they're noticeably worse than your average nightmare. Really,

449
00:27:20,160 --> 00:27:23,160
Speaker 1: so would you keep waking up from them? Mm hmmm,

450
00:27:24,119 --> 00:27:26,840
Speaker 1: that I don't remember. See, that's that's a big question

451
00:27:26,880 --> 00:27:30,520
Speaker 1: to me. Um. Well, let's talk about the anecdotal theory

452
00:27:30,640 --> 00:27:34,240
Speaker 1: of what is behind fever dreams. Right, So, when your

453
00:27:34,240 --> 00:27:37,000
Speaker 1: body is undergoing a fever, we said that your body

454
00:27:37,040 --> 00:27:41,280
Speaker 1: is not functioning at its top performance. Um, and that

455
00:27:41,320 --> 00:27:45,399
Speaker 1: includes the brain. The brain itself is an extremely special

456
00:27:45,560 --> 00:27:49,320
Speaker 1: organ if you didn't know already, it's like, I think

457
00:27:49,400 --> 00:27:53,240
Speaker 1: two of the body's mass, but it requires twenty of

458
00:27:53,280 --> 00:27:58,080
Speaker 1: the body's energy. Yeah, and the neurons compared to regular

459
00:27:58,119 --> 00:28:02,160
Speaker 1: old dumb cells. Uh uh, they they burn or they

460
00:28:02,200 --> 00:28:08,360
Speaker 1: need about between three times more energy than a regular

461
00:28:08,600 --> 00:28:11,479
Speaker 1: dumb cell in your body. Right. And so when all

462
00:28:11,480 --> 00:28:14,639
Speaker 1: these chemical processes, when all of this UM energy is

463
00:28:14,680 --> 00:28:19,080
Speaker 1: being exploited to power cells, UM, it produces the byproduct

464
00:28:19,160 --> 00:28:22,240
Speaker 1: of heat. So the brain is super sensitive to overheating

465
00:28:22,320 --> 00:28:26,240
Speaker 1: right already, just under normal circumstances, and it's generally taken

466
00:28:26,240 --> 00:28:30,000
Speaker 1: care of, uh by by your body, like it's you

467
00:28:30,040 --> 00:28:34,800
Speaker 1: know that it's cooled down and regulated. Right. So, Um,

468
00:28:34,840 --> 00:28:38,160
Speaker 1: if you have a fever and your brain is not

469
00:28:38,360 --> 00:28:44,480
Speaker 1: operating at optimal conditions, but you're asleep, so it's trying

470
00:28:44,520 --> 00:28:48,440
Speaker 1: to go through its normal processes. Um, if you have

471
00:28:48,520 --> 00:28:52,120
Speaker 1: a nightmare, it's entirely possible that that nightmare is going

472
00:28:52,160 --> 00:28:54,800
Speaker 1: to be far far worse because the normal processes have

473
00:28:54,920 --> 00:28:59,840
Speaker 1: broken down, or it's even further possible apparently. Um. The

474
00:29:00,000 --> 00:29:04,680
Speaker 1: amygdalas frequently implicated with nightmares because it has to do

475
00:29:04,720 --> 00:29:09,120
Speaker 1: with being terrified or angry or fearful. Um, the amigdala

476
00:29:09,320 --> 00:29:14,600
Speaker 1: might be functioning at an abnormal level and it's just

477
00:29:14,680 --> 00:29:18,560
Speaker 1: basically going haywired while you have a fever. Yeah, and

478
00:29:18,600 --> 00:29:21,320
Speaker 1: then the fact that most dreams occur during R E

479
00:29:21,480 --> 00:29:24,000
Speaker 1: M sleep, and I think that's when you're body is

480
00:29:24,120 --> 00:29:28,000
Speaker 1: warmest sleep anyway, right, that's when see, this is where

481
00:29:28,120 --> 00:29:30,840
Speaker 1: it all gets kind of hinky. During R E M sleep,

482
00:29:31,200 --> 00:29:34,400
Speaker 1: your hypothalamus says I'm done, I'm not working right now,

483
00:29:34,840 --> 00:29:38,200
Speaker 1: so it stops regulating temperature, which is usually why your

484
00:29:38,240 --> 00:29:40,640
Speaker 1: body temperature is lowest right before you wake up. I

485
00:29:40,640 --> 00:29:42,680
Speaker 1: thought it was highest right before you wake up. No,

486
00:29:42,760 --> 00:29:45,400
Speaker 1: it's highest in the afternoon while you're awake. It's lowest

487
00:29:45,520 --> 00:29:47,520
Speaker 1: right before you wake up. I feel like I always

488
00:29:47,520 --> 00:29:51,200
Speaker 1: wake up hot. You. I mean, you may be like

489
00:29:51,280 --> 00:29:53,440
Speaker 1: sleeping with too many blankets, your room might be a

490
00:29:53,440 --> 00:29:59,000
Speaker 1: little too warm, or maybe it's my stupid you know,

491
00:29:59,120 --> 00:30:02,040
Speaker 1: schedule of my see, I mean it could be you know,

492
00:30:02,120 --> 00:30:04,440
Speaker 1: it might have cut off a couple hours before or something. Right,

493
00:30:04,440 --> 00:30:06,720
Speaker 1: it could be right, so fires up after I get up.

494
00:30:06,760 --> 00:30:10,360
Speaker 1: Because supposedly, um, when you are sleeping and you're in

495
00:30:10,520 --> 00:30:14,040
Speaker 1: R E M sleep, your hypothalamus is not regulating temperature

496
00:30:14,120 --> 00:30:19,120
Speaker 1: during that period. So if you if you are already hot,

497
00:30:19,520 --> 00:30:24,680
Speaker 1: and remember high body temperature is associated with wakefulness, then

498
00:30:24,720 --> 00:30:27,960
Speaker 1: maybe you are waking up more frequently than you normally would,

499
00:30:28,240 --> 00:30:30,040
Speaker 1: and when you wake up in the middle of a dream,

500
00:30:30,080 --> 00:30:32,120
Speaker 1: you're more prone to remember it. If you wake up

501
00:30:32,120 --> 00:30:34,200
Speaker 1: in the middle of a nightmare, it's going to seem

502
00:30:34,200 --> 00:30:36,840
Speaker 1: even worse than one that you had and woke up

503
00:30:36,840 --> 00:30:39,800
Speaker 1: normally from. Yeah, I mean I had a series of

504
00:30:40,240 --> 00:30:43,840
Speaker 1: not nightmares last night, but just sort of anxiety dreams.

505
00:30:44,480 --> 00:30:46,680
Speaker 1: And I don't have any anxiety about anything right now.

506
00:30:46,720 --> 00:30:49,360
Speaker 1: I think it was just after reading all this stuff. Yeah,

507
00:30:49,960 --> 00:30:55,160
Speaker 1: I'm just suggestible you had anxiety dreams. Yeah, but not

508
00:30:55,240 --> 00:30:58,760
Speaker 1: about like nothing specific. No, like there's you know usually

509
00:30:58,760 --> 00:31:00,800
Speaker 1: if I have anxiety dreams and just like because something's

510
00:31:00,800 --> 00:31:03,760
Speaker 1: going on in my life, I'm anxious. But it was

511
00:31:03,800 --> 00:31:06,600
Speaker 1: just a research huh, I think so. I men, you're dedicated.

512
00:31:06,760 --> 00:31:09,760
Speaker 1: But they were also celebrity dreams because you know I've

513
00:31:09,760 --> 00:31:13,400
Speaker 1: talked about those before. No, Yeah, yeah, that I have

514
00:31:13,480 --> 00:31:15,960
Speaker 1: just celebrity dreams all the time. But they're just very

515
00:31:16,000 --> 00:31:20,120
Speaker 1: normal that I'm just like friends with celebrity people. But

516
00:31:20,200 --> 00:31:23,600
Speaker 1: were they were the anxiety written last night? Yes, Like

517
00:31:23,640 --> 00:31:26,000
Speaker 1: I was hanging out with a band Luna Dean were

518
00:31:26,080 --> 00:31:29,720
Speaker 1: um of Luna and that was but there was. I

519
00:31:29,760 --> 00:31:31,560
Speaker 1: can't remember exactly what was going on, but you know

520
00:31:31,680 --> 00:31:33,600
Speaker 1: that was anxiety involved, like I was trying to get

521
00:31:33,600 --> 00:31:37,120
Speaker 1: somewhere and couldn't get there, like the typical stupid dream stuff,

522
00:31:37,560 --> 00:31:40,920
Speaker 1: you know. But some Dean was in there somehow. Yeah.

523
00:31:41,320 --> 00:31:43,920
Speaker 1: Have you talked to him today? I don't know him,

524
00:31:44,000 --> 00:31:47,080
Speaker 1: but uh, I think I know why they were in there,

525
00:31:47,080 --> 00:31:52,080
Speaker 1: That's all I'll say. Okay, wink wink, I guess. So.

526
00:31:52,600 --> 00:31:54,520
Speaker 1: Here's another thing that was in our own article I

527
00:31:54,520 --> 00:31:58,240
Speaker 1: thought was interesting and just a little tidbit, was that, um,

528
00:31:58,720 --> 00:32:03,640
Speaker 1: some recreational drug like meth and ecstasy can raise brain temperatures.

529
00:32:04,320 --> 00:32:06,600
Speaker 1: That is one of the reasons they think that it

530
00:32:07,080 --> 00:32:09,600
Speaker 1: kills so many brain cells when you do those drugs. Yes,

531
00:32:09,640 --> 00:32:13,480
Speaker 1: supposedly you're not supposed to take ecstasy and warm climates. Yeah,

532
00:32:13,560 --> 00:32:18,600
Speaker 1: never have heard that. Yeah, just norway. Well there you

533
00:32:18,640 --> 00:32:23,920
Speaker 1: have it, only it's fall barred. Um what else is

534
00:32:23,920 --> 00:32:25,960
Speaker 1: there anything else in here? No? Man, I can't believe

535
00:32:26,000 --> 00:32:29,959
Speaker 1: we stretched this one out as far as we did. Alright,

536
00:32:30,240 --> 00:32:32,840
Speaker 1: we never have to talk about fever dreams again, Chuck good.

537
00:32:33,440 --> 00:32:35,760
Speaker 1: If you want to know more about fever dreams, well

538
00:32:35,760 --> 00:32:37,720
Speaker 1: you might as well start at how stuff works dot com.

539
00:32:37,760 --> 00:32:41,160
Speaker 1: There's nothing wrong with that, um. And you can also

540
00:32:41,240 --> 00:32:44,840
Speaker 1: just go around and look at how sparse the researches

541
00:32:44,880 --> 00:32:47,480
Speaker 1: on the internet for yourself. And if you are a

542
00:32:47,480 --> 00:32:50,720
Speaker 1: researcher and you know more stuff about fever dreams that

543
00:32:50,800 --> 00:32:54,280
Speaker 1: you can point us to let us know. UM. In

544
00:32:54,320 --> 00:32:57,280
Speaker 1: the meantime, I think I said search bars somewhere in there,

545
00:32:57,280 --> 00:33:02,320
Speaker 1: which means it's time for a listener mail. Uh, you

546
00:33:02,360 --> 00:33:04,560
Speaker 1: know what. I think another reason the anxiety dreams is

547
00:33:04,560 --> 00:33:09,840
Speaker 1: because I'm barreling through this season of Fargo. And yeah,

548
00:33:09,920 --> 00:33:12,280
Speaker 1: and the two episodes I watched last night, which I

549
00:33:12,360 --> 00:33:16,560
Speaker 1: believe we're if there are ten, I think it was

550
00:33:16,640 --> 00:33:21,360
Speaker 1: eight and nine, we're both just like ratcheted up with sin.

551
00:33:21,560 --> 00:33:23,600
Speaker 1: I'm sure that's what it was. And I think that

552
00:33:23,640 --> 00:33:25,360
Speaker 1: probably has something to do with it. That happens to

553
00:33:25,400 --> 00:33:28,160
Speaker 1: me sometimes I'll be watching something I won't realize how

554
00:33:28,200 --> 00:33:29,560
Speaker 1: on top of me it's gotten, and then all of

555
00:33:29,600 --> 00:33:32,080
Speaker 1: a sudden, like it goes to an ad and I'm

556
00:33:32,120 --> 00:33:36,280
Speaker 1: like really uptight about like this scratching washing machine sale

557
00:33:36,320 --> 00:33:39,240
Speaker 1: that's going on somewhere, and I don't understand why. I'm like,

558
00:33:39,280 --> 00:33:41,560
Speaker 1: oh wow, that TV show really got to me. Yeah,

559
00:33:41,600 --> 00:33:43,280
Speaker 1: I think I think Fargo had something to do it.

560
00:33:43,400 --> 00:33:46,000
Speaker 1: Think you may have nailed it. Um, all right, I'm

561
00:33:46,000 --> 00:33:49,240
Speaker 1: gonna call this one garden variety fan mail, which we

562
00:33:49,280 --> 00:33:52,160
Speaker 1: don't read a lot of these, so I'm going to

563
00:33:52,480 --> 00:33:55,600
Speaker 1: dig in. Hey, guys, that's all this is fan mail.

564
00:33:55,840 --> 00:33:58,400
Speaker 1: You guys are doing a great job, always have. It's

565
00:33:58,400 --> 00:34:01,040
Speaker 1: clear that with every episode do you take pains to

566
00:34:01,160 --> 00:34:04,120
Speaker 1: provide the most accurate information you can in the most

567
00:34:04,120 --> 00:34:06,920
Speaker 1: thoughtful way possible. How ironic that you would read this

568
00:34:07,000 --> 00:34:09,480
Speaker 1: on the fever dreams of Uh, there's never been more

569
00:34:09,520 --> 00:34:11,840
Speaker 1: evident to me than in the episodes you did on Puberty.

570
00:34:11,880 --> 00:34:13,600
Speaker 1: I know it's been a little while since he's came out,

571
00:34:14,080 --> 00:34:15,800
Speaker 1: but just listen to them, and it was touching to

572
00:34:15,800 --> 00:34:18,520
Speaker 1: see how frequently you tried to reassure young listeners what

573
00:34:18,600 --> 00:34:20,959
Speaker 1: they're experiencing is normal and that there was nothing wrong

574
00:34:21,000 --> 00:34:23,520
Speaker 1: about what was happening. To hear two grown men do

575
00:34:23,560 --> 00:34:26,200
Speaker 1: their best talk to young boys and girls about such

576
00:34:26,280 --> 00:34:29,759
Speaker 1: sensitive material was a pleasure. Yes, at times, I could

577
00:34:29,760 --> 00:34:34,280
Speaker 1: practically feel you nervously twitching while trying trying to discuss

578
00:34:34,800 --> 00:34:38,239
Speaker 1: um menstruation in an informative yet reassuring way. But it

579
00:34:38,320 --> 00:34:41,440
Speaker 1: was absolutely charming, just reaffirm what we've always known. You

580
00:34:41,440 --> 00:34:45,439
Speaker 1: two are just a pair of great dudes. That's nice. Yeah,

581
00:34:44,480 --> 00:34:47,279
Speaker 1: I've only been listening for a few years, but I'm

582
00:34:47,280 --> 00:34:51,000
Speaker 1: a lifetime fan. Now. Uh, if you're keeping count, like

583
00:34:51,040 --> 00:34:52,480
Speaker 1: to put it in a vote for d C for

584
00:34:52,800 --> 00:34:58,480
Speaker 1: live shows. Uh, Josh, h E d G E E.

585
00:34:59,719 --> 00:35:03,120
Speaker 1: Sorry E d G E is edge and then add

586
00:35:03,120 --> 00:35:08,600
Speaker 1: two els edgel Josh edgel or a gel, I like

587
00:35:08,800 --> 00:35:13,880
Speaker 1: edgel for ed Gil, Gil for Edgar. I think edgel

588
00:35:14,360 --> 00:35:17,880
Speaker 1: edgel sounds like a kid next door. Josh, it's Josh

589
