WEBVTT - Heat Waves! 0:00:01.480 --> 0:00:04.280 Welcome to Stuff you should know, a production of I 0:00:04.360 --> 0:00:13.400 Heart Radio. Hey, and welcome to the podcast. I'm Josh, 0:00:13.440 --> 0:00:16.439 and there's chucking. It's just us, but that's okay because 0:00:16.480 --> 0:00:20.440 we today are doing stuff you should know. The heat 0:00:20.480 --> 0:00:25.840 wave addition, that's the heat brows of the fact. Have 0:00:25.960 --> 0:00:28.680 you been singing that song all day? I've been trying 0:00:28.800 --> 0:00:32.040 so hard not to and it's not working. How about you? 0:00:32.920 --> 0:00:36.519 Oh man, it's Martha Invent and the Vandellas. How can 0:00:36.560 --> 0:00:39.239 you not? Yeah? The problem is is all I just 0:00:39.960 --> 0:00:43.960 it's just this constant loop of heat wave like heat wave, 0:00:44.040 --> 0:00:46.639 I know, heat wave. Just that's it over and that's 0:00:46.640 --> 0:00:49.520 the only part I know. And it's terrible. I think 0:00:49.560 --> 0:00:52.480 I know that. One of the first lines is uh 0:00:53.000 --> 0:00:56.080 whenever we oh near me. Oh, that's the same song. 0:00:56.600 --> 0:01:00.200 I think, so right, because I'm I thinking of something. No, 0:01:00.320 --> 0:01:02.480 I think it is. But every movie that ever uses 0:01:02.520 --> 0:01:04.520 it just uses that first line and then starts to 0:01:04.560 --> 0:01:06.280 fade out before they get to the heat wave card. 0:01:06.319 --> 0:01:09.800 So I never put two and two together. A great song, 0:01:10.240 --> 0:01:12.920 great song, for sure, But you don't want just heat 0:01:12.959 --> 0:01:15.399 wave on a loop in your head. I can tell you. 0:01:16.080 --> 0:01:17.880 Uh no, No, I just looked at the lyrics and 0:01:17.920 --> 0:01:21.840 I'm wrong anyway, But whenever I'm with him, Okay, but 0:01:21.920 --> 0:01:23.640 it's that's what you're talking about. It's not like a 0:01:23.680 --> 0:01:27.120 totally different song or something. Whenever I'm with him, something 0:01:27.120 --> 0:01:30.520 inside starts to burning and I'm filled with desire. Heat wave? 0:01:30.880 --> 0:01:33.320 Could it be a devil in me? Heat wave? The 0:01:33.319 --> 0:01:39.880 way love is supposed to be? He'd wave, Yes, All right, 0:01:40.200 --> 0:01:43.240 let's done. Let's never speak of that again. Sexy song. 0:01:43.319 --> 0:01:45.680 I didn't realize it was that sexy. Well, sure, she 0:01:45.800 --> 0:01:48.240 talking about getting all hot for a dude, you know, 0:01:48.360 --> 0:01:52.200 I mean, that's your over. That's not what There's nothing 0:01:52.240 --> 0:01:55.160 sexy about the heat wave that we're talking about. No, 0:01:55.520 --> 0:02:00.760 deadly maybe the antithesis of sexy. Yeah, they think about 0:02:00.800 --> 0:02:04.040 it heat wave sex. And there's such a thing as 0:02:04.080 --> 0:02:07.040 cold waves, which will touch on briefly. They are very 0:02:07.120 --> 0:02:09.680 much related to heat waves are kind of its polar opposite, 0:02:09.760 --> 0:02:14.040 if you'll excuse the pun, but the you could make 0:02:14.080 --> 0:02:16.320 a case that that would be far sexier than a 0:02:16.400 --> 0:02:20.919 heat wave. Yeah. At least you're you know, warming yourself up, right, 0:02:21.200 --> 0:02:24.880 That's exactly right. Uh, And boy, we we used a 0:02:24.880 --> 0:02:30.480 lot of great weather website references for this one, right, Yeah, yeah, great, great, 0:02:30.800 --> 0:02:34.320 great segue there, chuck. So, um, we got some info 0:02:34.520 --> 0:02:40.679 from from Noah j No. Actually, the thing is, I 0:02:40.760 --> 0:02:43.440 can't even be taken seriously when I'm trying to be 0:02:43.560 --> 0:02:48.000 serious and genuine like that was genuine. I'm still learning. 0:02:49.000 --> 0:02:52.360 So that was so Noah gave us a bunch of information, 0:02:52.440 --> 0:02:56.320 your nephew. Um. There's also the Center for Climate Change 0:02:56.320 --> 0:03:02.280 and Energy Solutions. Is this my cue? Yep uh, World 0:03:02.280 --> 0:03:07.160 Weather Attribution, the New York Times, the failing New York Times, NASA, 0:03:07.800 --> 0:03:10.400 ACU Weather, Yeah, and a bunch more, but those are 0:03:10.400 --> 0:03:13.119 the ones that we got the meat of this stuff from. Yeah, 0:03:13.160 --> 0:03:15.480 and we're talking about heat waves, which is the I 0:03:15.560 --> 0:03:17.000 was about to call it a phenomenon. I don't know 0:03:17.280 --> 0:03:20.040 if it is categorized at that, but it's a weather event. 0:03:20.160 --> 0:03:23.800 It's a natural disaster. Well yeah, and as we'll see, 0:03:23.800 --> 0:03:26.720 one of one of the worst. It is when there 0:03:26.720 --> 0:03:31.320 are consecutive days where the temperature is higher than usually 0:03:31.440 --> 0:03:33.800 is that is to say, higher than the historical average. 0:03:34.440 --> 0:03:36.640 But there's no like it depends on where you are. 0:03:36.680 --> 0:03:39.520 What is uh, what a heat wave is like, It's 0:03:39.560 --> 0:03:43.400 not necessarily like three days and it's eight degrees hotter 0:03:43.400 --> 0:03:45.760 than usual for those three days. Now, because it varies 0:03:45.800 --> 0:03:48.920 region to region, like in New Hampshire, a heat wave 0:03:48.960 --> 0:03:52.839 of two days, two days or two consecutive days where 0:03:52.840 --> 0:03:56.000 it's ninety degrees fare hight or more is a heat wave. 0:03:57.000 --> 0:03:59.040 And that's just like yawn to those of us down 0:03:59.080 --> 0:04:02.800 in the southeast. That's like a fairly nice day. Yeah, 0:04:02.880 --> 0:04:06.240 it's regional, like spices that go in hot dogs, right. 0:04:06.560 --> 0:04:09.240 But the thing is is like that depends the reason 0:04:09.280 --> 0:04:11.440 that they do that. The reason there's no single definition 0:04:11.440 --> 0:04:14.320 for heat waves because people are acclimated to different kinds 0:04:14.360 --> 0:04:17.119 of weather, and if you're not acclimated to warm weather, 0:04:17.160 --> 0:04:20.520 it's going to affect you and your body a lot worse. 0:04:20.520 --> 0:04:23.120 So it makes a lot of sense. But the two 0:04:23.160 --> 0:04:26.039 days in a row as low as ninety degrees fair 0:04:26.040 --> 0:04:28.080 at height, that's the minimum that I've seen in the 0:04:28.160 --> 0:04:32.200 United States that constitutes a legit heat wave. I'm sorry, 0:04:32.240 --> 0:04:37.200 I'm sorry, a legit heat wave. Oh boy, we're gonna 0:04:37.240 --> 0:04:41.360 do that the whole time. I think I'm going to okay. Um, 0:04:41.839 --> 0:04:44.520 this one speaks to my heart because, as everyone who's 0:04:44.560 --> 0:04:47.039 ever listening to the show much knows and as you 0:04:47.120 --> 0:04:51.920 my friends certainly know, I am a I'm a polar bear. 0:04:52.200 --> 0:04:56.520 So the sun and humidity is not good for Chuck. 0:04:56.760 --> 0:04:58.640 I hate it. I hate it. I grew up in 0:04:58.640 --> 0:05:01.200 the South, and it's it's worse now. It feels like 0:05:01.240 --> 0:05:04.080 it's not like I've gotten acclimated, Like you know, it's 0:05:04.120 --> 0:05:07.440 easy to say you get acclimated. But even as as 0:05:07.520 --> 0:05:10.239 much as I sweat, which is a I can't imagine 0:05:10.240 --> 0:05:11.719 how hot I would be if I didn't sweat like 0:05:11.720 --> 0:05:13.960 I sweat. Well, yeah, you'd be like one of those 0:05:13.960 --> 0:05:17.120 people who can't sweat and can die from it. But 0:05:17.160 --> 0:05:20.039 when I lived in l a uh, it can get 0:05:20.120 --> 0:05:23.120 very hot out there, but generally if you can park 0:05:23.160 --> 0:05:27.520 it under a tree, you might get a breeze and 0:05:27.680 --> 0:05:29.840 you can sweat and you're cooling down pretty good. But 0:05:30.560 --> 0:05:33.640 it's it's there's no relief when you live in the 0:05:33.680 --> 0:05:35.920 South because of humidity. We're going to talk about all that, 0:05:36.000 --> 0:05:38.160 but I just want to kind of set set up 0:05:38.279 --> 0:05:41.680 my personal involvement with heat waves, which is boo thumbs down. 0:05:42.880 --> 0:05:46.360 You're personally involved through sweatiness, is what you're saying. Yeah, 0:05:46.360 --> 0:05:48.520 and when those heat waves, especially the late heat waves 0:05:49.400 --> 0:05:51.800 in the summer when it should be cooling down come through. 0:05:51.839 --> 0:05:54.000 It's just it makes me mad. Yeah, those are not 0:05:54.120 --> 0:05:56.800 fun because your your bodies in your mind has been 0:05:56.839 --> 0:05:59.640 like okay, great, it's fall, and then you're just dog 0:05:59.720 --> 0:06:01.960 days summer again. It's terrible. I'm with you on that. 0:06:02.640 --> 0:06:05.160 But how did these things come about to begin with? 0:06:05.240 --> 0:06:09.000 Why is it hot for a week straight way hotter 0:06:09.040 --> 0:06:11.159 than it normally is, and why doesn't is just cool 0:06:11.240 --> 0:06:13.000 down every night? Well, first we should say, because I 0:06:13.040 --> 0:06:15.880 don't want to lose anybody this early on if they're like, uh, 0:06:16.120 --> 0:06:18.480 two days in a row of ninety degree weather? Why 0:06:18.520 --> 0:06:21.400 are you guys even talking about this? The reason we 0:06:21.440 --> 0:06:24.320 are talking about this because, like we said, Chuck, Noah 0:06:24.320 --> 0:06:27.600 classifies heat waves as a disaster, and a lot of 0:06:27.640 --> 0:06:31.360 really terrible stuff can happen during a heat wave, even 0:06:31.400 --> 0:06:35.560 of just a few days. Like it's it's a an invisible, silent, 0:06:36.200 --> 0:06:40.360 deadly natural disaster that we're only beginning to awaken. Too, 0:06:41.640 --> 0:06:46.080 silent but deadly. So as you're saying how do heat 0:06:46.080 --> 0:06:49.040 waves work, you're kind of set me up for that one, right, Well, yeah, 0:06:49.080 --> 0:06:50.240 but I thought you were going to hit him with 0:06:50.279 --> 0:06:53.719 the big stat which is heat waves kill more people 0:06:53.800 --> 0:06:58.120 than all other natural disasters combined. Um or I think 0:06:58.120 --> 0:07:02.080 you saw somewhere else all but hurricane. But point being, 0:07:02.440 --> 0:07:04.360 they kill a lot of people, like way more than 0:07:04.400 --> 0:07:07.400 you think. Yeah, and even if they don't necessarily kill 0:07:07.560 --> 0:07:10.520 more than uh, kill more people at least in the 0:07:10.640 --> 0:07:13.360 United States. That it was just the statistic I saw. 0:07:13.960 --> 0:07:18.200 Um then all other natural disasters combined, that at the 0:07:18.320 --> 0:07:21.680 very least, it kills more people per year than all 0:07:21.720 --> 0:07:24.880 other natural disasters. It's the deadliest kind of natural disaster. 0:07:25.400 --> 0:07:28.920 The thing is is it doesn't happen all at once, 0:07:29.200 --> 0:07:31.480 like say a flood that takes a bunch of people's 0:07:31.480 --> 0:07:39.080 lives in a very a very acute area, right concentrated area. Um. 0:07:39.160 --> 0:07:41.480 It happened slowly over the course of days in a 0:07:41.560 --> 0:07:44.080 very large region, and people just kind of die. And 0:07:44.120 --> 0:07:47.120 it's not immediately apparent like like, oh, I found you 0:07:47.160 --> 0:07:50.280 in floodwater, you drowned in a flood. It's I found 0:07:50.320 --> 0:07:53.520 you dead on your sofa, you know, in your apartment. 0:07:53.640 --> 0:07:55.720 And I'm not maybe you had a heart attack or 0:07:55.720 --> 0:07:58.280 something like that. It's it's not That's what I was saying. 0:07:58.280 --> 0:08:00.400 We're just beginning to awaken to it because it's not 0:08:00.680 --> 0:08:03.680 an obvious natural disaster, but it is most decidedly a 0:08:03.760 --> 0:08:06.840 natural disaster. Yeah, that's a good point. Like it's not 0:08:06.920 --> 0:08:10.440 quite as grabby in the news. I mean, they certainly 0:08:10.440 --> 0:08:13.560 report on it, but it's not and you know, the 0:08:13.600 --> 0:08:16.240 news is is well, I don't want to talk about 0:08:16.240 --> 0:08:19.200 the news. Um, let's talk about heat waves. Heat waves, 0:08:19.480 --> 0:08:23.080 that's right. So the whole thing about a heat wave 0:08:23.160 --> 0:08:28.520 is it's a basically a warm mass of hot air 0:08:29.600 --> 0:08:32.520 that's a just a lope or no, a high pressure system. 0:08:32.559 --> 0:08:35.480 So let me just restate that less confusingly. It's a 0:08:35.559 --> 0:08:39.240 high pressure system that's made up of very stagnant, still 0:08:39.360 --> 0:08:42.680 warm air that kind of finds its way over a 0:08:42.720 --> 0:08:45.800 region and doesn't move for a little while and things 0:08:45.880 --> 0:08:50.320 get really oppressive during that period. Yeah, And these high 0:08:50.320 --> 0:08:54.360 pressure systems are just part of the normal weather patterns 0:08:54.360 --> 0:08:58.640 and they generally kind of circulate clockwise and kind of 0:08:58.640 --> 0:09:02.439 move on through. Uh. The jet stream takes care of that, thankfully. 0:09:02.480 --> 0:09:06.240 That that west to east air current that moves pushes 0:09:06.240 --> 0:09:08.920 all the weather around, always shoving the weather around in 0:09:08.960 --> 0:09:12.400 the northern hemisphere at least. Yeah, well, come on, is 0:09:12.400 --> 0:09:17.559 there any other hemisphere, sorry, America's centric or anything. No, 0:09:17.600 --> 0:09:21.320 not at all, but are in the northern hemisphere. The 0:09:21.440 --> 0:09:26.040 jet stream hits us about at the belt between Canada's 0:09:26.080 --> 0:09:30.640 shirt and America's jeans. And like I said, it usually 0:09:30.640 --> 0:09:33.560 pushes stuff around and it'll get hot and then it'll 0:09:33.600 --> 0:09:37.240 push that hot stuff out. But during the summertime, the 0:09:37.320 --> 0:09:40.600 jet stream slows down. Uh. They have found that overall, 0:09:40.640 --> 0:09:42.320 and we're gonna talk, you know, quite a bit about 0:09:42.320 --> 0:09:46.760 climate change. Overall, it's slowing down period some, but in 0:09:46.800 --> 0:09:51.320 the summertime it's it definitely slows down from its you know, 0:09:51.400 --> 0:09:55.120 two and fifty mile per hour or so peak. And 0:09:55.200 --> 0:09:59.000 that's gonna obviously keep that hot weather there a little longer. Yeah, 0:09:59.040 --> 0:10:03.040 even under normal conditions, let alone climate change conditions. So 0:10:03.120 --> 0:10:06.360 when all of the all those factors are are kind 0:10:06.400 --> 0:10:09.400 of falling into place where the jet stream is feeling 0:10:09.440 --> 0:10:13.040 a little logy and not moving too quickly, and there's 0:10:13.040 --> 0:10:15.480 a big mass of hot air that kind of moves 0:10:15.600 --> 0:10:18.440 up as a high pressure front and just settles in 0:10:18.520 --> 0:10:22.680 over a region, you've got everything you need for that 0:10:23.080 --> 0:10:27.880 massive hot air to just stay put and continue heating up, 0:10:28.080 --> 0:10:31.000 which is the big problem because a high pressure um 0:10:31.440 --> 0:10:37.600 weather system forces air downward and it's hot air too. Normally, 0:10:37.880 --> 0:10:40.080 you have hot air at the surface, or air that 0:10:40.200 --> 0:10:42.560 warms up at the surface and it moves upward, it 0:10:42.600 --> 0:10:46.600 floats upward, and it's replaced by cool air that comes in, 0:10:46.840 --> 0:10:48.880 and you've got breezes. Well, one of the things that's 0:10:48.880 --> 0:10:51.520 the hallmark of a high pressure system is there there 0:10:51.559 --> 0:10:55.040 ain't no breezes because it's just sitting there pushing the 0:10:55.040 --> 0:10:58.600 air downward towards the surface of the Earth, which prevents 0:10:58.640 --> 0:11:01.680 that air from rye eazing, so there's no cool air 0:11:01.720 --> 0:11:03.920 to come in, so there's no breeze. But also because 0:11:03.920 --> 0:11:05.880 that air is just sitting there at the surface, it's 0:11:05.880 --> 0:11:08.680 just getting warmer and warmer and warm warmer. And the 0:11:08.720 --> 0:11:11.800 surface air temperature is what we're concerned with, because it's 0:11:11.880 --> 0:11:15.880 the temperature of the air about two meters above the 0:11:15.880 --> 0:11:18.400 Earth's surface above the ground, so it's about six and 0:11:18.400 --> 0:11:20.400 a half feet, which is where a lot of us 0:11:20.400 --> 0:11:24.200 are trying to take a breath in this really hot air. Well, 0:11:24.320 --> 0:11:27.440 a lot of you taller people, sure, but even still, 0:11:27.480 --> 0:11:29.400 if you stood on your tippy toes, it would affect 0:11:29.440 --> 0:11:32.200 you a lot too. Well, the other thing that happens 0:11:32.200 --> 0:11:34.680 to because that air isn't rising, that means it's not 0:11:34.679 --> 0:11:38.559 gonna rain. Uh, and rain obviously can be away to 0:11:38.640 --> 0:11:42.400 cool things down. So it just it's sort of acts 0:11:42.440 --> 0:11:46.640 as this uh, it's sort of like a feedback loop 0:11:46.679 --> 0:11:51.520 basically where the hotter it gets, the hotter it's gonna get. Yeah. 0:11:51.559 --> 0:11:54.480 And even the other thing about a high pressure front 0:11:54.559 --> 0:11:58.520 is it pushes like air away from it, outward from 0:11:58.559 --> 0:12:01.480 the edges of it, so there's no fronts coming in 0:12:01.520 --> 0:12:04.640 to like kind of relieve it. It's so the stronger 0:12:04.679 --> 0:12:07.880 they get, the more all of these factors contribute, and then, 0:12:07.880 --> 0:12:11.200 like you said, creates this positive feedback cycle and basically 0:12:11.240 --> 0:12:13.360 you're just totally at the mercy of the jet stream 0:12:13.400 --> 0:12:16.480 to move this thing away eventually, and it can take 0:12:16.520 --> 0:12:19.560 some time. And so that's what a heat wave is. 0:12:19.600 --> 0:12:21.760 It's when one of these like all these factors kind 0:12:21.760 --> 0:12:24.600 of come together and this massive hot air settles in 0:12:24.640 --> 0:12:26.920 over a region and just keeps getting hotter and hotter. 0:12:27.440 --> 0:12:30.760 And in the daytime, that's that's the like the money 0:12:31.400 --> 0:12:33.880 time as far as people are concerned with heat waves, 0:12:33.880 --> 0:12:36.800 because the sun's out, it's really really hot. The temperatures 0:12:36.800 --> 0:12:39.440 are really high, and it's pretty bad. No one's going 0:12:39.480 --> 0:12:42.240 to argue that the daytime during a heat wave stinks, 0:12:42.800 --> 0:12:45.800 But it's the night time that's the more insidious part. 0:12:45.880 --> 0:12:50.079 That's the real problem with the with the heat wave, right, yeah, 0:12:50.160 --> 0:12:53.200 I mean, even if it gets really hot, but it's 0:12:53.200 --> 0:12:56.600 not a heat wave. The earth helps itself out by 0:12:56.600 --> 0:12:59.560 cooling down at night. Your body, like everything cools down 0:12:59.559 --> 0:13:01.920 at night. It's a it's a great chance to just 0:13:02.040 --> 0:13:04.520 kind of, you know, kick off your shoes and like 0:13:04.679 --> 0:13:10.080 relax and recharge. Yeah, like humans, the human body needs it. Uh, 0:13:10.120 --> 0:13:14.400 Animals bodies need it. The earth itself needs it. The 0:13:14.440 --> 0:13:17.440 buildings and the concrete and the asphalt and the steel 0:13:17.440 --> 0:13:20.920 and the glass. It all depends on cooling down some 0:13:21.080 --> 0:13:23.520 at night. So it can be like, well, I'm gonna 0:13:23.520 --> 0:13:25.440 get hot again tomorrow, but at least I cooled down 0:13:25.440 --> 0:13:28.839 tonight and you know, kind of relaxed and like you said, 0:13:29.080 --> 0:13:31.880 repaired my energy. But when a heat wave comes, it's 0:13:31.920 --> 0:13:35.520 not cooling down at night. So I mean, just imagine yourself. 0:13:35.559 --> 0:13:37.320 If you never get a chance to cool down at 0:13:37.400 --> 0:13:40.040 night and you stay hot, then that sun comes up 0:13:40.080 --> 0:13:43.960 the next day, it's gonna be twice as bad, Yeah, 0:13:43.960 --> 0:13:46.800 because you're starting from a higher set point at the beginning, 0:13:46.840 --> 0:13:48.360 you know. And that's one of the hallmarks of a 0:13:48.400 --> 0:13:51.839 heat wave is it's hot even before the sun comes up. 0:13:51.880 --> 0:13:54.440 That's which is not pleasant, and it's certainly not good 0:13:54.480 --> 0:13:58.480 sleeping weather. Those are the worst, man like, especially here 0:13:58.480 --> 0:14:01.280 in the South, when you go out, like you go 0:14:01.360 --> 0:14:03.520 to let your dog out at eleven o'clock at night, 0:14:03.520 --> 0:14:05.840 and it's like eighty seven degrees or something, you just 0:14:05.880 --> 0:14:09.480 start sweating immediately before that. It's just brutal. It's pretty bad. 0:14:09.880 --> 0:14:12.400 All right. Well, let's take a break. I need to 0:14:12.440 --> 0:14:16.839 go I don't know, soaking a bathtub or something. I'm 0:14:16.840 --> 0:14:20.000 getting a little hot down here. Uh, And we'll talk 0:14:20.000 --> 0:14:36.440 about the dreaded humidity right after this. Learn it's stuff 0:14:36.480 --> 0:15:06.040 with Joshua John Okay, Chuck lay it on him that 0:15:06.200 --> 0:15:11.560 very famous phrase that actually holds true. Um, youth has 0:15:11.560 --> 0:15:15.640 wasted on the young, sure that one, but also early 0:15:15.720 --> 0:15:24.080 bird gets the worm and UM never say candy man 0:15:24.200 --> 0:15:26.920 into a mirror. Well, it's certainly not three times in 0:15:26.960 --> 0:15:30.400 a row. It's not the heat, it's the humidity. There's 0:15:30.520 --> 0:15:33.880 the one I was looking for, right that's the one, 0:15:33.960 --> 0:15:36.680 and that's true. I mean we were talking about humidity earlier. 0:15:36.720 --> 0:15:38.920 That is what you know the humans have as this 0:15:39.000 --> 0:15:42.440 great mechanism built in a kind of a self contained 0:15:42.480 --> 0:15:46.040 air conditioning system which is called sweat. And if it's 0:15:46.120 --> 0:15:48.480 if the air is fairly dry outside, and like I 0:15:48.600 --> 0:15:51.400 mentioned getting under that shade tree in Los Angeles, you 0:15:51.440 --> 0:15:54.280 can sweat and that water is gonna evaporate off of 0:15:54.320 --> 0:15:56.080 you and a cool breeze will come through and it 0:15:56.120 --> 0:15:59.240 actually feels good. And that is how you regulate and 0:15:59.280 --> 0:16:03.880 cool down. When the humidity happens, it's hard to near 0:16:03.920 --> 0:16:06.880 impossible for that sweat to really cool you down. You'll 0:16:06.920 --> 0:16:12.320 still be sweating, but it won't have that same effect, right, Um, yeah, 0:16:12.520 --> 0:16:15.520 it's it's just there's no place for that sweat to go. 0:16:15.760 --> 0:16:18.320 It doesn't just move into the air because there's already 0:16:18.400 --> 0:16:20.680 so much water vapor into the air. So the higher 0:16:20.720 --> 0:16:23.360 the humidity is, the worst off it is for you. 0:16:24.160 --> 0:16:27.960 And then if you take high temperatures as well, that 0:16:28.080 --> 0:16:32.200 combination of high humidity and high temperature can be really bad. 0:16:32.720 --> 0:16:35.400 And back in the seventies there was a guy, actually 0:16:35.440 --> 0:16:39.440 in nineteen seventy nine, somebody named R. G. Steadman. They 0:16:39.480 --> 0:16:43.680 came up in nineteen seventy nine with assessment of sultry nous, 0:16:43.720 --> 0:16:46.040 which we call today the heat index. It was the 0:16:46.040 --> 0:16:48.000 paper that put the heat index out there, and the 0:16:48.040 --> 0:16:51.680 heat index is basically, yeah, it really is. You know, 0:16:51.720 --> 0:16:55.000 it sounds it sounds like a Tennessee Williams play or 0:16:55.040 --> 0:16:58.480 something like that. So the heat index makes a lot 0:16:58.520 --> 0:17:02.480 of sense because when it's really humid out and it's 0:17:03.200 --> 0:17:06.440 high in temperature, that humidity makes it feel even hotter 0:17:06.560 --> 0:17:09.680 because we have trouble sweating. So so R. G. Steadman 0:17:09.760 --> 0:17:12.600 came up with the heat index that kind of gives 0:17:12.640 --> 0:17:16.320 you a much better understanding of what the actual temperature 0:17:16.320 --> 0:17:18.400 as far as your human body is concerned. That's why 0:17:18.400 --> 0:17:21.280 they also call it the apparent temperature or the fuels 0:17:21.320 --> 0:17:24.880 like temperature. Yeah, and that's the only one I care about. 0:17:25.720 --> 0:17:27.760 I don't even know why they less regular temperature. It 0:17:27.760 --> 0:17:30.520 should just be heat indecks and wind chill in the winter, 0:17:31.320 --> 0:17:33.480 because that's the only thing that matters. And I guess 0:17:33.560 --> 0:17:35.879 you know, it's it's like showing your math or something. 0:17:35.960 --> 0:17:38.239 So they have to go through it all, but as 0:17:38.240 --> 0:17:40.440 far as your human body is concerned, those are really 0:17:40.480 --> 0:17:43.600 the only two measures that matter, or at least for me. Yeah. 0:17:43.800 --> 0:17:45.600 So you know how sometimes you can end up down 0:17:45.640 --> 0:17:47.680 a rabbit hole and like not find a way out 0:17:47.680 --> 0:17:49.720 and you have to just crawl backwards out of it, 0:17:49.880 --> 0:17:52.040 and you're you're kind of worse off for the wear 0:17:52.080 --> 0:17:54.600 because you went a little mad in there. Sure that 0:17:54.720 --> 0:18:00.920 happened to me. With humidity, heat index, evaporation, condensation, I'm 0:18:00.960 --> 0:18:03.679 like researching it. Yeah, yeah, yeah, um, And I'm like 0:18:03.720 --> 0:18:07.960 there's a lot of there's some some connections here between 0:18:08.000 --> 0:18:11.040 all these things that my brain is not making. I'm 0:18:11.080 --> 0:18:13.639 just sensing that it's all very much connected, and I'm 0:18:13.680 --> 0:18:15.880 even reading stuff that's saying it's connected. I just can't 0:18:15.920 --> 0:18:19.280 figure out how it's all connected because it's not as 0:18:19.320 --> 0:18:23.879 simple as like humidity or you know, the heat index 0:18:23.960 --> 0:18:27.160 is humidity times temperature divided by two or something like that. 0:18:27.160 --> 0:18:29.920 That's not how it works. It's way more sophisticated than that, 0:18:30.680 --> 0:18:33.480 and it takes into account a lot of different stuff 0:18:33.520 --> 0:18:37.439 so that if you if you actually put a lower 0:18:37.480 --> 0:18:41.800 temperature in with higher humidity, it will bring the temperature down. 0:18:42.359 --> 0:18:45.359 And then there's some temperatures like say seventy degrees where 0:18:45.440 --> 0:18:47.280 it doesn't really matter what you do with the humidity, 0:18:47.320 --> 0:18:49.720 it's still just gonna feel like seventy degrees. So there's 0:18:49.760 --> 0:18:52.080 like a lot of different weirdness in there. But the 0:18:52.080 --> 0:18:53.960 thing is the upshot of all this. I was just 0:18:54.040 --> 0:18:56.440 kind of confessing and getting off my chest that I'm 0:18:56.480 --> 0:18:59.960 a little obsessed with this and if any any meteorologists 0:19:00.040 --> 0:19:02.240 or climatologists can explain all this to me, I would 0:19:02.240 --> 0:19:05.680 love to hear it. But as far as heat waves 0:19:05.680 --> 0:19:08.680 are concerned, if you have high temperatures and high humidity, 0:19:08.920 --> 0:19:12.000 some really astounding stuff happens when you put those together. 0:19:12.040 --> 0:19:15.320 As far as the heat index is concerned. Yeah, And 0:19:16.000 --> 0:19:20.440 just not to harp on my personal um sweating issues. 0:19:21.480 --> 0:19:23.119 We've talked about it a lot over the years, but 0:19:23.680 --> 0:19:26.240 it's the embarrassing thing for me is not that I've 0:19:26.240 --> 0:19:28.640 sweat a lot, because a It's that's why I never 0:19:28.720 --> 0:19:31.520 had like acne growing up, because I'm just constantly sweating 0:19:31.560 --> 0:19:34.280 everything through. We've got like the cleanest pores in the world, 0:19:35.040 --> 0:19:37.480 um and it you know, it helps cool me down, 0:19:37.480 --> 0:19:43.080 But it's when it's like seventy six degrees and super humid, 0:19:43.760 --> 0:19:46.159 and other people are like or even in the sixties 0:19:46.320 --> 0:19:49.040 or fifties, and they're like, it's really cool. Why are 0:19:49.040 --> 0:19:51.760 you sweating, like because it's humid. I don't care if 0:19:51.800 --> 0:19:54.960 it's forty degrees. If it's super humid, I might break 0:19:55.000 --> 0:19:57.959 a sweat. Yeah, it gets through. If you're sweating at 0:19:57.960 --> 0:20:01.320 forty degrees, that's that's some sweaty us for sure. Maybe 0:20:01.359 --> 0:20:04.959 not forty fifty. We could do some tests, all right, 0:20:05.040 --> 0:20:09.600 let's do oh yeah, let's do some science. I'm gone up. Yeah, 0:20:09.720 --> 0:20:12.600 like a humidity lab or something. Okay, but I still 0:20:12.600 --> 0:20:15.000 get to get a lab coat, right Sure of the 0:20:15.000 --> 0:20:19.080 color of my choosing. Um, I'll let you select from 0:20:19.119 --> 0:20:23.000 three colors of my choosing. What are they? Cinnamon, powder, blue, 0:20:23.240 --> 0:20:26.720 and orange? Okay? Great, okay, any one of those, then 0:20:26.800 --> 0:20:29.919 that's mine. It's mine. Banana yellow was going to be 0:20:29.960 --> 0:20:32.480 in there, but you missed. You missed the boat. At 0:20:32.560 --> 0:20:38.080 least you didn't make me dress up in a banana costume. Uh, yeah, 0:20:38.080 --> 0:20:40.760 I was. It's funny. I was shopping for Halloween for 0:20:40.760 --> 0:20:42.680 this year and I kind of didn't want to go 0:20:42.960 --> 0:20:45.679 is a devo, and so I was looking up for 0:20:45.720 --> 0:20:50.560 those yellow jumpsuits and I was waylaid because you kind 0:20:50.560 --> 0:20:52.320 of end up having to be whatever your kid says 0:20:52.359 --> 0:20:54.640 you have to be. So I think we're all gonna 0:20:54.640 --> 0:20:56.920 be spooky things this year, but I had to put 0:20:56.960 --> 0:20:58.639 the devo thing on the back burner. You could be 0:20:58.680 --> 0:21:03.359 like zombie Divo. Not a bad idea, No, it's not. 0:21:03.480 --> 0:21:06.240 It's a great idea. Yeah, you can be zombie anything. 0:21:06.240 --> 0:21:09.680 That's kind of the beauty of the zombie Zombie b York, 0:21:09.880 --> 0:21:14.800 Zombie Mark Mother's Ball, Zombie b York. I like that, 0:21:15.960 --> 0:21:21.520 Just wear that Swan dress and walk around saying I 0:21:21.560 --> 0:21:23.399 was trying to think of how Buyork would say brains 0:21:23.400 --> 0:21:28.040 but not of my head. Couldn't put it together. That 0:21:28.160 --> 0:21:32.280 was perfect thing. Uh. So you mentioned insidious effects and 0:21:32.480 --> 0:21:37.159 we're going to talk about those because, uh, very wide reaching. 0:21:37.200 --> 0:21:40.480 It's not just people get hot and people die. Uh. 0:21:40.520 --> 0:21:43.640 It affects kind of everything on the planet. And it's 0:21:43.640 --> 0:21:46.880 easy to kind of think of heat stroke and dehydration 0:21:46.960 --> 0:21:49.000 and something like that during the day, like you said, 0:21:49.040 --> 0:21:51.080 because that's when you count on it, and that's when 0:21:51.119 --> 0:21:53.359 you might take precautions, which, by the way, to go 0:21:53.480 --> 0:21:56.320 listen to our Desert Survival episode for that kind of stuff. 0:21:56.520 --> 0:22:00.879 Oh yeah, good tips there, but not like you said, 0:22:01.080 --> 0:22:04.320 it's that's when it's really bad because the human body 0:22:04.359 --> 0:22:07.960 really depends on that rest and that reset and that 0:22:08.080 --> 0:22:11.639 cool down. And if you stay hot, your body and 0:22:11.760 --> 0:22:13.360 is you know, especially if you have like high bread 0:22:13.480 --> 0:22:17.080 high blood pressure or like heart issues, it's working overtime 0:22:17.160 --> 0:22:20.119 at night when it should be cooling down because you 0:22:20.640 --> 0:22:23.080 I think you're like lowest body temperature of the twenty 0:22:23.119 --> 0:22:26.479 four hour cycle is during sleep. So if you're not 0:22:26.640 --> 0:22:29.360 hitting that cool down cycle, then everything is just doing 0:22:29.400 --> 0:22:32.520 a lot of extra work. Yeah, in particular your heart is. 0:22:32.720 --> 0:22:35.199 And when your heart is working hard and then it 0:22:35.200 --> 0:22:38.280 has to work hard again the next day, it's like 0:22:38.320 --> 0:22:41.560 that that set point doesn't ever or the set point 0:22:41.600 --> 0:22:44.240 starts higher the next day. So after a few days 0:22:44.240 --> 0:22:46.080 of this, especially if you have a bum ticker to 0:22:46.119 --> 0:22:49.880
