00:00:01,840 --> 00:00:04,360
Speaker 1: Welcome to brain Stuff, a production of I Heart Radio.

2
00:00:06,640 --> 00:00:09,440
Speaker 1: Hey brain Stuff, Lauren Vogel Bomb here with a classic

3
00:00:09,480 --> 00:00:13,160
Speaker 1: podcast episode for you. This one goes into the science,

4
00:00:13,400 --> 00:00:17,360
Speaker 1: and there is real science behind what hanger is and

5
00:00:17,440 --> 00:00:22,280
Speaker 1: how you can combat it. Hey brain Stuff, Lauren vogel

6
00:00:22,280 --> 00:00:25,280
Speaker 1: bomb here. Many of us are familiar with the feelings

7
00:00:25,320 --> 00:00:29,040
Speaker 1: that low blood sugar produces. Crankiness sets in. Some of

8
00:00:29,120 --> 00:00:33,280
Speaker 1: us get abusive, others downright hostile. Usually a glass of juice,

9
00:00:33,280 --> 00:00:36,320
Speaker 1: a candy bar, or some other well timed snack clears

10
00:00:36,400 --> 00:00:40,720
Speaker 1: this honest to goodness condition colloquially called being angry, a

11
00:00:40,760 --> 00:00:44,280
Speaker 1: cross between hungry and angry. I call it. You wouldn't

12
00:00:44,280 --> 00:00:47,400
Speaker 1: like me when I'm hungry? But why does hangar happen?

13
00:00:47,920 --> 00:00:51,919
Speaker 1: Some people have good self control and others don't. In

14
00:00:51,960 --> 00:00:56,000
Speaker 1: recent years, scientists have linked self control to nutrition. They

15
00:00:56,000 --> 00:00:59,520
Speaker 1: say self control requires energy. If your body is mining

16
00:00:59,560 --> 00:01:02,680
Speaker 1: for energy and finds done while self control goes out

17
00:01:02,720 --> 00:01:05,360
Speaker 1: the window. It all comes down to the amount of

18
00:01:05,400 --> 00:01:09,039
Speaker 1: glucose our body's process. The human body is a machine

19
00:01:09,120 --> 00:01:12,319
Speaker 1: made of meat. Like all machines, it needs fuel. That

20
00:01:12,440 --> 00:01:14,760
Speaker 1: fuel comes in the form of glucose a k A

21
00:01:14,920 --> 00:01:18,199
Speaker 1: blood sugar. Our bodies convert the carbohydrates and the foods

22
00:01:18,200 --> 00:01:21,080
Speaker 1: we eat into glucose. The body then stores some of

23
00:01:21,080 --> 00:01:23,840
Speaker 1: that glucose in the liver and muscles as glycogen, and

24
00:01:23,920 --> 00:01:27,120
Speaker 1: stores some as fat. When our blood sugar is low,

25
00:01:27,200 --> 00:01:30,360
Speaker 1: the hypothalamus, the portion of the brain involved in hormone production,

26
00:01:30,480 --> 00:01:33,440
Speaker 1: among other things, gets bent out of shape, throwing the

27
00:01:33,440 --> 00:01:37,600
Speaker 1: body's hormones out of whack and suppressing serotonin. A neurotransmitter,

28
00:01:38,240 --> 00:01:41,840
Speaker 1: Serotonin has a hand in controlling mood and appetite. It's

29
00:01:41,880 --> 00:01:44,759
Speaker 1: often called the feel good neurotransmitter because it can relieve

30
00:01:44,800 --> 00:01:49,680
Speaker 1: symptoms of depression and anxiety. If your body stops processing serotonin,

31
00:01:49,960 --> 00:01:53,480
Speaker 1: your mood can shift. You can get tired or forget things.

32
00:01:53,560 --> 00:01:57,840
Speaker 1: Your concentration becomes poor. You might even get angry. Still,

33
00:01:57,960 --> 00:02:00,480
Speaker 1: your blood sugar has to drop like a rock from

34
00:02:00,600 --> 00:02:03,080
Speaker 1: seventy to a hundred milligrams per DESI leader to less

35
00:02:03,080 --> 00:02:06,200
Speaker 1: than fifty five milligrams per DESI leader for the Hangar

36
00:02:06,280 --> 00:02:11,079
Speaker 1: Games to begin in April. Study published in the journal

37
00:02:11,120 --> 00:02:14,560
Speaker 1: p n a S confirmed the people really do get angry.

38
00:02:15,160 --> 00:02:18,360
Speaker 1: The researchers studied whether low glucose levels were responsible for

39
00:02:18,440 --> 00:02:22,079
Speaker 1: greater aggression in married couples. The scientists studied a hundred

40
00:02:22,080 --> 00:02:25,040
Speaker 1: and seven couples and monitored their glucose levels twice a

41
00:02:25,120 --> 00:02:28,720
Speaker 1: day for twenty one days. To measure their aggressive impulses,

42
00:02:28,919 --> 00:02:32,200
Speaker 1: the researchers asked each person to stick between zero and

43
00:02:32,280 --> 00:02:36,440
Speaker 1: fifty one pins into a voodoo style doll representing their spouse,

44
00:02:36,720 --> 00:02:40,640
Speaker 1: with more pins representing greater anger. When the three weeks

45
00:02:40,639 --> 00:02:43,320
Speaker 1: were up, the researchers asked each couple to play a

46
00:02:43,480 --> 00:02:47,760
Speaker 1: game designed to measure aggression. The scientists allowed the winner

47
00:02:47,800 --> 00:02:50,440
Speaker 1: of the game to blast the loser with loud noise

48
00:02:50,520 --> 00:02:54,240
Speaker 1: as both sat in separate chambers. There was a catch, however,

49
00:02:54,840 --> 00:02:59,240
Speaker 1: each person wasn't actually turning up the volume. Regardless, those

50
00:02:59,240 --> 00:03:02,520
Speaker 1: participants with low glucose levels believed they were hammering their

51
00:03:02,520 --> 00:03:06,560
Speaker 1: spouses with high decibels of irritating noise. The authors concluded

52
00:03:06,760 --> 00:03:10,600
Speaker 1: results suggest that interventions designed to provide individuals with metabolic

53
00:03:10,680 --> 00:03:15,280
Speaker 1: energy might foster more harmonious couple interactions. In other words,

54
00:03:15,560 --> 00:03:19,040
Speaker 1: eats some carbs before you argue. And this study was

55
00:03:19,080 --> 00:03:22,120
Speaker 1: just one of several linking self control to glucose levels

56
00:03:22,120 --> 00:03:25,120
Speaker 1: in the brain. Another study concluded that those who drank

57
00:03:25,160 --> 00:03:27,639
Speaker 1: a beverage high in glucose were less aggressive than those

58
00:03:27,639 --> 00:03:31,200
Speaker 1: who did not. Still, another study found an indirect relationship

59
00:03:31,240 --> 00:03:35,440
Speaker 1: between diabetes, which is marked by poor glucose metabolism, aggressiveness,

60
00:03:35,560 --> 00:03:39,480
Speaker 1: and increased self control. Although causation is always hard to

61
00:03:39,480 --> 00:03:42,600
Speaker 1: pin down, these studies suggested that a spoonful of sugar

62
00:03:42,880 --> 00:03:46,920
Speaker 1: helps diminish violent or aggressive behavior in the short term.

63
00:03:46,960 --> 00:03:50,400
Speaker 1: Of course, consuming too much sugar and other simple carbohydrates

64
00:03:50,440 --> 00:03:53,160
Speaker 1: can lead to poorer glucose metabolism in the long run,

65
00:03:53,480 --> 00:03:55,680
Speaker 1: so while a cookie maybe a quick fix if you

66
00:03:55,680 --> 00:03:59,240
Speaker 1: need to focus, it's best overall to consume balanced meals

67
00:03:59,240 --> 00:04:01,880
Speaker 1: and snacks can hating enough protein and fats along with

68
00:04:01,880 --> 00:04:04,960
Speaker 1: those sweet carbs to keep your blood sugar nice and even.

69
00:04:10,440 --> 00:04:12,920
Speaker 1: Today's episode is based on the article is Hanger a
