1 00:00:00,469 --> 00:00:03,110 hypothermia it's something you see all 2 00:00:03,110 --> 00:00:03,120 hypothermia it's something you see all 3 00:00:03,120 --> 00:00:05,180 hypothermia it's something you see all too often in movies starring Leonardo 4 00:00:05,180 --> 00:00:05,190 too often in movies starring Leonardo 5 00:00:05,190 --> 00:00:08,839 too often in movies starring Leonardo DiCaprio but what is it exactly and how 6 00:00:08,839 --> 00:00:08,849 DiCaprio but what is it exactly and how 7 00:00:08,849 --> 00:00:12,410 DiCaprio but what is it exactly and how does it really happen our body is always 8 00:00:12,410 --> 00:00:12,420 does it really happen our body is always 9 00:00:12,420 --> 00:00:14,419 does it really happen our body is always trying to maintain a balmy temperature 10 00:00:14,419 --> 00:00:14,429 trying to maintain a balmy temperature 11 00:00:14,429 --> 00:00:18,769 trying to maintain a balmy temperature of around 98.6 degrees Fahrenheit or 37 12 00:00:18,769 --> 00:00:18,779 of around 98.6 degrees Fahrenheit or 37 13 00:00:18,779 --> 00:00:21,920 of around 98.6 degrees Fahrenheit or 37 degrees Celsius eppela thermia occurs 14 00:00:21,920 --> 00:00:21,930 degrees Celsius eppela thermia occurs 15 00:00:21,930 --> 00:00:24,140 degrees Celsius eppela thermia occurs when our body loses heat faster than we 16 00:00:24,140 --> 00:00:24,150 when our body loses heat faster than we 17 00:00:24,150 --> 00:00:26,810 when our body loses heat faster than we can produce it and hypothermia doesn't 18 00:00:26,810 --> 00:00:26,820 can produce it and hypothermia doesn't 19 00:00:26,820 --> 00:00:29,210 can produce it and hypothermia doesn't only strike sinking ship victims and 20 00:00:29,210 --> 00:00:29,220 only strike sinking ship victims and 21 00:00:29,220 --> 00:00:31,609 only strike sinking ship victims and 19th century fur trappers wandering in 22 00:00:31,609 --> 00:00:31,619 19th century fur trappers wandering in 23 00:00:31,619 --> 00:00:34,310 19th century fur trappers wandering in the wilderness studies estimate that 24 00:00:34,310 --> 00:00:34,320 the wilderness studies estimate that 25 00:00:34,320 --> 00:00:37,700 the wilderness studies estimate that about 1500 Americans die of accidental 26 00:00:37,700 --> 00:00:37,710 about 1500 Americans die of accidental 27 00:00:37,710 --> 00:00:40,940 about 1500 Americans die of accidental hypothermia each year in fact exposure 28 00:00:40,940 --> 00:00:40,950 hypothermia each year in fact exposure 29 00:00:40,950 --> 00:00:42,860 hypothermia each year in fact exposure to the cold is responsible for twice as 30 00:00:42,860 --> 00:00:42,870 to the cold is responsible for twice as 31 00:00:42,870 --> 00:00:45,729 to the cold is responsible for twice as many deaths as heat exposure annually 32 00:00:45,729 --> 00:00:45,739 many deaths as heat exposure annually 33 00:00:45,739 --> 00:00:48,049 many deaths as heat exposure annually young children and the elderly are 34 00:00:48,049 --> 00:00:48,059 young children and the elderly are 35 00:00:48,059 --> 00:00:51,080 young children and the elderly are especially vulnerable so why is 36 00:00:51,080 --> 00:00:51,090 especially vulnerable so why is 37 00:00:51,090 --> 00:00:54,680 especially vulnerable so why is hypothermia so dangerous most heat loss 38 00:00:54,680 --> 00:00:54,690 hypothermia so dangerous most heat loss 39 00:00:54,690 --> 00:00:57,410 hypothermia so dangerous most heat loss occurs when unprotected surfaces radiate 40 00:00:57,410 --> 00:00:57,420 occurs when unprotected surfaces radiate 41 00:00:57,420 --> 00:00:59,029 occurs when unprotected surfaces radiate heat away from the body 42 00:00:59,029 --> 00:00:59,039 heat away from the body 43 00:00:59,039 --> 00:01:01,910 heat away from the body in addition wearing wet clothes makes 44 00:01:01,910 --> 00:01:01,920 in addition wearing wet clothes makes 45 00:01:01,920 --> 00:01:05,000 in addition wearing wet clothes makes heat loss even worse and windchill can 46 00:01:05,000 --> 00:01:05,010 heat loss even worse and windchill can 47 00:01:05,010 --> 00:01:07,130 heat loss even worse and windchill can quickly escalate the situation because 48 00:01:07,130 --> 00:01:07,140 quickly escalate the situation because 49 00:01:07,140 --> 00:01:09,260 quickly escalate the situation because it strips away the thin layer of heat on 50 00:01:09,260 --> 00:01:09,270 it strips away the thin layer of heat on 51 00:01:09,270 --> 00:01:12,770 it strips away the thin layer of heat on the skin surface as your temperature 52 00:01:12,770 --> 00:01:12,780 the skin surface as your temperature 53 00:01:12,780 --> 00:01:16,219 the skin surface as your temperature drops your body and brain fire back your 54 00:01:16,219 --> 00:01:16,229 drops your body and brain fire back your 55 00:01:16,229 --> 00:01:18,140 drops your body and brain fire back your thyroid and adrenal glands release a 56 00:01:18,140 --> 00:01:18,150 thyroid and adrenal glands release a 57 00:01:18,150 --> 00:01:20,120 thyroid and adrenal glands release a flood of hormones that boost your 58 00:01:20,120 --> 00:01:20,130 flood of hormones that boost your 59 00:01:20,130 --> 00:01:22,010 flood of hormones that boost your metabolism heart rate and blood pressure 60 00:01:22,010 --> 00:01:22,020 metabolism heart rate and blood pressure 61 00:01:22,020 --> 00:01:25,880 metabolism heart rate and blood pressure in the brain the hypothalamus tells your 62 00:01:25,880 --> 00:01:25,890 in the brain the hypothalamus tells your 63 00:01:25,890 --> 00:01:28,640 in the brain the hypothalamus tells your blood vessels to constrict this moves 64 00:01:28,640 --> 00:01:28,650 blood vessels to constrict this moves 65 00:01:28,650 --> 00:01:30,050 blood vessels to constrict this moves the blood further from the skin's 66 00:01:30,050 --> 00:01:30,060 the blood further from the skin's 67 00:01:30,060 --> 00:01:32,420 the blood further from the skin's surface where heat can escape 68 00:01:32,420 --> 00:01:32,430 surface where heat can escape 69 00:01:32,430 --> 00:01:34,820 surface where heat can escape your hypothalamus also signals your 70 00:01:34,820 --> 00:01:34,830 your hypothalamus also signals your 71 00:01:34,830 --> 00:01:37,190 your hypothalamus also signals your muscles to shiver which kicks your 72 00:01:37,190 --> 00:01:37,200 muscles to shiver which kicks your 73 00:01:37,200 --> 00:01:39,740 muscles to shiver which kicks your metabolism into overdrive two to five 74 00:01:39,740 --> 00:01:39,750 metabolism into overdrive two to five 75 00:01:39,750 --> 00:01:43,070 metabolism into overdrive two to five times the normal rate at this point 76 00:01:43,070 --> 00:01:43,080 times the normal rate at this point 77 00:01:43,080 --> 00:01:45,380 times the normal rate at this point you're on the brink if you don't get to 78 00:01:45,380 --> 00:01:45,390 you're on the brink if you don't get to 79 00:01:45,390 --> 00:01:47,360 you're on the brink if you don't get to safety soon you'll hit severe 80 00:01:47,360 --> 00:01:47,370 safety soon you'll hit severe 81 00:01:47,370 --> 00:01:50,030 safety soon you'll hit severe hypothermia and be in serious trouble 82 00:01:50,030 --> 00:01:50,040 hypothermia and be in serious trouble 83 00:01:50,040 --> 00:01:52,670 hypothermia and be in serious trouble eventually even your brain will grow 84 00:01:52,670 --> 00:01:52,680 eventually even your brain will grow 85 00:01:52,680 --> 00:01:54,890 eventually even your brain will grow colder when this happens it stops 86 00:01:54,890 --> 00:01:54,900 colder when this happens it stops 87 00:01:54,900 --> 00:01:56,630 colder when this happens it stops functioning properly which can make you 88 00:01:56,630 --> 00:01:56,640 functioning properly which can make you 89 00:01:56,640 --> 00:01:59,690 functioning properly which can make you feel dizzy disoriented and even want to 90 00:01:59,690 --> 00:01:59,700 feel dizzy disoriented and even want to 91 00:01:59,700 --> 00:02:03,080 feel dizzy disoriented and even want to strip naked before too long you'll run 92 00:02:03,080 --> 00:02:03,090 strip naked before too long you'll run 93 00:02:03,090 --> 00:02:06,170 strip naked before too long you'll run the risk of permanent brain damage but 94 00:02:06,170 --> 00:02:06,180 the risk of permanent brain damage but 95 00:02:06,180 --> 00:02:08,570 the risk of permanent brain damage but just how long do you have it's hard to 96 00:02:08,570 --> 00:02:08,580 just how long do you have it's hard to 97 00:02:08,580 --> 00:02:10,820 just how long do you have it's hard to know because each situation and person 98 00:02:10,820 --> 00:02:10,830 know because each situation and person 99 00:02:10,830 --> 00:02:12,430 know because each situation and person is completely different 100 00:02:12,430 --> 00:02:12,440 is completely different 101 00:02:12,440 --> 00:02:15,410 is completely different however radiologist Anna bagging home 102 00:02:15,410 --> 00:02:15,420 however radiologist Anna bagging home 103 00:02:15,420 --> 00:02:18,020 however radiologist Anna bagging home currently holds the record for surviving 104 00:02:18,020 --> 00:02:18,030 currently holds the record for surviving 105 00:02:18,030 --> 00:02:21,380 currently holds the record for surviving the coldest body temperature after a 106 00:02:21,380 --> 00:02:21,390 the coldest body temperature after a 107 00:02:21,390 --> 00:02:23,540 the coldest body temperature after a skiing accident she endured 80 minutes 108 00:02:23,540 --> 00:02:23,550 skiing accident she endured 80 minutes 109 00:02:23,550 --> 00:02:25,610 skiing accident she endured 80 minutes in freezing cold water her body 110 00:02:25,610 --> 00:02:25,620 in freezing cold water her body 111 00:02:25,620 --> 00:02:28,729 in freezing cold water her body temperature had plummeted to 56.7 112 00:02:28,729 --> 00:02:28,739 temperature had plummeted to 56.7 113 00:02:28,739 --> 00:02:31,400 temperature had plummeted to 56.7 degrees Fahrenheit or thirteen point 114 00:02:31,400 --> 00:02:31,410 degrees Fahrenheit or thirteen point 115 00:02:31,410 --> 00:02:34,490 degrees Fahrenheit or thirteen point seven degrees Celsius hopefully that 116 00:02:34,490 --> 00:02:34,500 seven degrees Celsius hopefully that 117 00:02:34,500 --> 00:02:36,530 seven degrees Celsius hopefully that never happens to you but here are some 118 00:02:36,530 --> 00:02:36,540 never happens to you but here are some 119 00:02:36,540 --> 00:02:38,539 never happens to you but here are some tips for treating hypothermia with 120 00:02:38,539 --> 00:02:38,549 tips for treating hypothermia with 121 00:02:38,549 --> 00:02:41,570 tips for treating hypothermia with several safety measures immediate first 122 00:02:41,570 --> 00:02:41,580 several safety measures immediate first 123 00:02:41,580 --> 00:02:44,509 several safety measures immediate first aid victims can also be treated with 124 00:02:44,509 --> 00:02:44,519 aid victims can also be treated with 125 00:02:44,519 --> 00:02:47,090 aid victims can also be treated with warm IV fluids and salt water solutions 126 00:02:47,090 --> 00:02:47,100 warm IV fluids and salt water solutions 127 00:02:47,100 --> 00:02:50,000 warm IV fluids and salt water solutions and you can help avoid hypothermia with 128 00:02:50,000 --> 00:02:50,010 and you can help avoid hypothermia with 129 00:02:50,010 --> 00:02:52,220 and you can help avoid hypothermia with some safety measures like
