How To Train Your Body To Survive Extreme Cold and Heat – Science Experiment

We’ve all been there, one moment you’re lying
in bed comfortably wrapped up in a cocoon of blankets, blissfully warm and peaceful. Then the next your alarm is going off and
before you know it you’re trudging through another cold winter morning to go work eight
hours at a job you hate, trying not to think about the fact that you’ll be repeating this
routine tomorrow, and every day after that. Until you die. Or maybe you’re stuck in the dog days of summer,
in the midst of another record-breaking heat wave because global warming is definitely
not real, and panting desperately trying to fan yourself and find some relief. Truth is, most people would rather live our
lives in a comfortably room-temperature world of seventy degrees Fahrenheit, but our reality
routinely puts up against the bitter elements, extreme cold or extreme heat. If you live somewhere insane like Australia,
you get both- plus every animal there can kill you, in both hot and cold. But what if you could train yourself to resist
the effects of extreme temperatures? We’ve all read about modern supermen, with
the power to withstand extreme heat or extreme cold and do things that would seem like they’d
kill just about any other person alive. What about you though, the average joe? Could you realistically train your body to
survive extreme cold? Wim Hof is a dutch man known as an extremeophile,
and has earned the nickname “The Iceman”. In fact you’ve probably seen him featured
already on our show. Since he was a teenager Hof has been routinely
subjecting himself to extreme cold, and he’s learned not only to love it, but thrive in
it. He’s completed several marathons completely
barefoot in the Arctic Circle, once spent over an hour swimming under ice, and has hiked
almost the entire height of Mount Everest wearing only shorts. Yet Hof is definitely not immune to the effects
of the cold, as a matter of fact during his first attempt to set a record for swimming
under ice, he had to be rescued by a diver after his cornea began to freeze. Yes, you heard that correctly- corneas can
apparently freeze, and all that did was slow Hof down. He beat the record the very next day. So then how does he do these incredible feats? Hof is well known, and often criticized, for
marketing what he terms the Wim Hof method. While reviews are mixed, the method is fairly
simple and consists of engaging in regular meditation and elaborate breathing exercises. According to the method, you first begin with
thirty cycles of breathing meant to induce controlled hyperventilation. You inhale filling the lungs completely, which
means starting your breath down in the stomach and slowly expanding your lungs upwards. Then you release the breath, but without actually
exhaling- instead you let the pressure in your lungs force air out, before inhaling
again. Once you’ve mastered thirty cycles of controlled
hyperventilation, you then focus on controlling your body’s response to being deprived of
oxygen. You do this by taking deep breaths in, holding
it in briefly, and then completely expelling all the air out of your lungs. With empty lungs, you then resist the urge
to breathe in as long as possible. You might feel yourself drifting into oxygen-depravation
panic, but if you can hold out long enough you’ll actually eventually receive a boost
of oxygen as your liver releases oxygen-rich blood that it keeps stored for emergencies
like this. Freedivers who swim without oxygen often practice
hitting this point, and warn that the hardest part is simply keeping your cool and not freaking
out. The third step is to then work on your breath
retention. After mastering the complete exhalation exercise,
you then repeat, and when your urges to breathe get incredibly strong, you then take a full,
deep breath in and hold it for 15-20 seconds. Altogether, a complete work out should include
three consecutive rounds of all three steps, and this Hof claims will help you master your
ability to resist the effects of the cold. But, does it work? Well, surprisingly, yes, it does. Scientists have discovered that resisting
the effects of cold is more to do with your own mental perception and willpower rather
than anything biological. Studies on people who have learned to resist
the cold show that their core body temperature remains pretty much the same as a regular
person’s, it’s simply their perception of cold that’s different. For them, the same cold that sends you scurrying
into a pile of blankets is merely a light breeze. Of Course biology does help though, and scientists
have also found that individuals who regularly expose themselves to extreme cold actually
develop fat deposits known as brown fat. This is the same type of fat you had as a
baby, and is largely to thank for your chubby, cute appearance as a newborn. Babies are pretty terrible about keeping body
heat in, so the body is able to burn this fat much more efficiently than regular fat,
which helps keep it warm. If you regularly expose yourself to extreme
cold, you too can hack your body into believing it needs to generate this type of fat deposits,
and in turn they will help keep you warm. The trick though of course is to undergo what
extremophiles term acclimatization, or the process of gradually increasing exposure to
extreme cold. Sorry, but eating a bunch of donuts on the
couch isn’t going to get you the precious brown fat you need for your underwear-only
trip to the north pole- it’s just going to get you regular fat. So how do you acclimate to extreme cold? First, start with your willpower, because
if you don’t have much of it you’ll never get used to the cold. You can start though by regularly immersing
yourself in cold water. In South Korea there is a community of women
free divers who regularly dive for pearls in the freezing ocean, wearing nothing more
than a cotton suit. Women of all ages engage in this diving, even
women as old as 90. The regular exposure to cold water has toughened
up the women to the effects of cold on their bodies, and the good news is that you too
can be made as tough as a Korean granny. You can start by taking a shower every morning,
which you should already be doing, only now you’ll be doing it with only cold water. Start by exposing yourself for thirty seconds
at the end of a nice hot shower, then gradually increase the amount of time until eventually
you’re taking full-on cold showers. You’ll be well on your way to hiking through
antarctica in your birthday suit and you’ll save a fortune on your water bill- that’s
a double-win. If you live somewhere with snow, then it’s
time to kick it up a notch. The antarctic explorer H.R. Bowers was well
known for stripping completely naked every morning and dumping buckets of cold water
and slush over himself. You however can start with a Wim Hof technique
often called “snow laying”, and you guessed it, it’s as simple as laying on snow wearing
as little as possible. Just like the shower, regularly increase the
amount of time you spend exposed to the snow. If you’re not somewhere snowbound though,
then you can replicate this by filling a tub full of ice and sliding in. The longer you can stay in the closer you’ll
be to calling yourself a proper Iceman. Pretty soon you’ll be toasting cokes with
polar bears wearing nothing but sandals, though we should warn you that sudden exposure to
extreme cold does come at risk of a heart attack- so make sure you’re in decent health
before you attempt any of this and consult a doctor. Also, Coca-Cola lies and polar bears will
100% eat you on sight, though luckily for you they’ll all be dead from global warming
soon. We’ve now conquered one half of the planet,
wearing nothing but Duck Tales themed boxers and a smile- but what about heat? For heating we are turning to one of our own
wilderness survival gurus who’s had regular experience in desert environments with temperatures
well above 100 degrees fahrenheit- or whatever people who never landed on the moon measure
with. Just kidding, we really all should be using
a single measuring system, and it’s kind of silly we don’t. Anyways, tolerating heat is also a mental
affair, though unlike the cold, the body actually comes first. In extreme temperatures the body attempts
to cool itself off by sweating profusely, the water acting as a radiating fluid which
more easily enables heat to transfer from your body to the ambient air. That little trick by the way is what made
humans the top species on earth- while other animals were killing prey with sharp claws
and fangs, we simply ran our prey to death, and typically did so during the hottest times
of the day when animals who can’t sweat or sweat very poorly, were most vulnerable to
dying of overheating. Meanwhile our awesome sweat glands pumped
away the entire time, keeping us from dying as we chased our prey for miles at a time. But the real reason why our ancient ancestors
didn’t keel over dead from the heat, and so many modern suburbia Spartan-challenge-try-outs
do, has to do with water. We investigated this issue carefully, and
discovered that top scientists have learned that sweat consists mainly of water. So if you aren’t properly hydrated, your body
isn’t going to have much moisture to work with and help vent deadly heat being generated
within your body. Of course your body needs water for pretty
much anything it does though, so the real trick to surviving extreme heat, is to simply
stay hydrated. Incredibly you can lose as much as a liter
of water per hour in a hot environment if engaged in strenuous activity, and considering
that most doctors recommend you drink 1.5 to 2 liters of water every day during normal
activity, you can quickly see what the problem is. The trick is going to be to keep consuming
water during your time in the heat, with our desert guru recommending you drink at least
eight liters a day the entire time you’re in extreme heat. You’ll want to consume this water at a moderate
pace however, as extreme heat can make the stomach quite sensitive and drinking too much
water at once could actually lead you to vomiting, and unless you enjoy eating vomit, you’re
going to be losing out on precious liters of water. Instead just pace yourself as you drink, taking
frequent sips. If you’re out in extreme heat for a long time
though then water alone will eventually not be enough, and you’ll need to replace precious
minerals such as potassium. Due to sugars and other ingredients your body
doesn’t need unless under extreme stress, sports drinks are terrible to drink if you’re
just sitting on the couch all day doing nothing more than yelling at informative youtube shows
in the comments section. Adding sports drink to your hydration routine
in extreme heat though will keep you in tip-top shape, and as long as you protect your exposed
skin from the sun, there’s really no limit to how long you can tolerate even scorching
temperatures. Maintaining hydration is key, though overhydrating
can also be deadly and lead to a condition known as water intoxication. Don’t worry though, that’s pretty rare and
your body will pretty readily warn you of this condition- though if you’re truly in
the middle of record-setting heat, there’s little risk of this happening. What tips can you share for surviving extreme
heat or cold? Ever been somewhere really hot or really cold? Let us know in the comments! And as always if you enjoyed this video don’t

  • The best way to train your body is from exposure*. If you make it out okay then you can say you are that much more capable for extreme temperature swings. *lol

  • a tip for surviving extreme temperatures is just not to be in them lol

  • South Australia one day it got to 52 decrease Celsius in the shade

  • Can relate to that first part about working I eat glicey begals and work ewends now.

  • I allready like freezing water so in almost set for that only need to do the training and learn to do it out of water

  • Except the brown fat theory turned out to be proven false, but the rest of it is cool.

  • 1:30 "over an hour swimming under ice" – so he can breathe underwater too?

  • Interesting video

  • Coco cola made right now lol……Dislike comments and Bears eat you on SIGHT!!! ??????

  • If it’s so hot, how is snow possible? ?

  • Bruh yesterday it was 90 and now it’s 40 gotta love Texas

  • In hot weather there is a point (especially under heavy load) where you sweat more than you can intake. You can be dehydrated (dry throat, skin, headache…) while there are two liters of water in your stomach. At this point it's better to pour the water on yourself rather than drinking it. As a semi-pro cyclist I have experienced this sometimes. Also I can confirm that drinking isotonic drinks helps you a lot! You can absorb more liquid that way than your body would normally do.

  • In Chicago, we can go to sleep during a blizzard and wake up to a heat wave.

  • Lol wow that dude is insane

  • Here in Thailand normally it around 37c but in hot day it around 40c

  • “Ever been somewhere really hot or really cold?” Ever been to Michigan?

  • Biggest tip, consider going somewhere colder than Australia or just sit in a pool 24/7 like me

  • 0:14 on the right that is Michael Scott from the office do not change my mind about it.

  • It's called joining the millitary you'll get to go to alot of hot places

  • This video was so passive aggressive…I love it

  • Global warming actually isn't real.

  • Im an australian who likes the cold, or so i thought till i realised 20c isnt cold to most people.

  • As someone from Arizona you gotta adapt to the heat or you die. Simple as that

  • 0:26 killed all the "global warming isnt real" community with a single sentence

  • i live in alask so yes

    edit: thanks for adding that bit 🙂

  • I have run in hot weather due because I live in southern California bad thing I sweat a lot

  • Well here in New England we can have 100+ degree summers and -30 winters does that count as extreme lol.

  • 2:31 possible sign of oxygen boost from liver; Increased Alertness, Feeling Revitalised(if you’ve been feeling.. tired..-ish), and Overall feeling great

  • As a Kansan we get bellow 0 F and over 100 F often. In winter and summer respectively.

  • Did you know:
    there are enough bones in a human body to create an entire skeleton?

  • Ironic, wim "Hof" Hoth from star wars

  • Them: How do you wear a hoodie in the summer?! it's like 90 degrees!!!

    People insecure about their bodies: HMMM

  • Save polar bears!

  • Temperature's one thing but also Think of the vast variety of environmental aspects that are also dangerous. PH, air pressure, centrifugal force, g force, etc. We as humans are fragile entities. Whether or not becoming immune to everything is possible I don't know though. It would probably be a great video idea though.

  • Hoff is the epitome of black metal

  • Don't you hate when someone tells you to breathe, and your rebel side goes, "i'd rather die" and so you either consciously know you're breathing or you refuse to do it. And you realize that no matter what you decide to do, it was influenced by someone commanding you to breathe, and you're like, "i wanna punch that someone right in the gabba now."

  • Better get used to the cold because soon I will send you to the eternal abyss inside my frigid basement.

  • Can you use celcius rather tha fahrenheit

  • Eh,you can do any of that all you want but you can't escape frostbite and losing fingers etc.

  • I wear shorts in 30 degree weather but get cold when it’s room temp it’s weird

  • "what about you though, the average joe"
    -The infographics show (2019, man who found out who joe is)

  • Man it was 38 degrees in Australia today and I didn't sweat that much

  • Save your outfits on your horse for the right temperatures

  • They get more aggressive every episode

  • Make video on Hackers

  • Fact when your cold you want to sleep because it warms your body

  • Step one: live in Alaska
    Step two: repet step one

  • You won't have to train your self if you know UNAAGI

  • Your graphics are the worst.

  • In my Way Of ignoring heat Is My Mentality, Not ignoring The body needs what it needs. I Mostly ignore the heat and stay persistent on what I'm trying to do in the heat Rather then Dwell on it Just because I'm sweating or Its "Hot outside" cold on the other hand I try to do but it doesnt Come close to the more immune part of me with heat

  • Lol. We have this thing where our body regulates itself which is a process called homeostasis. It's the reason we sweat when we're hot and we shiver when we're cold. Wow look at that, new news hahahahaha jk. But srsly your body could do so many amazing things to keep you alive and you might not even be aware of it.


  • Drink water only when you feel thirsty not because you're hot. The reason for this is because if drink too much water you can sweat out salt which your body needs. I've seen this time and time again where people will pass out or even feel light headed. Not because they weren't drinking enough water but because they over drank

  • 6:42 thank you

  • Total concentration breathing technique

  • You vs Kabir singh

  • 70 degrees F, aka 21 C is a spring temperature in Europe, so…. 🙂

  • I worked in the mines in South Africa as a mechatronics technician for 4 years and something they do during initial training is "Heat tollerance training". This is where they train your body to sweat quickly(even in high humidity, since development ends normaly uses a lot of water which increases the humidity, but the temperature remains at over 30°C and much much higher sometimes) to ensure your body remains functional under mining temperatures. This was something amazing to experience, but 6 years after leaving the mining industry my body still reacts the same way(even though the training only lasted 3 weeks). A temperature of 28°C will cause my body to start sweating a lot more than usual people, since this is what it was trained to do. So a little warning to all who want to attempt the things from this video. Your body will adapt and learn quickly, but unlearning these things seems like it takes forever. Thank you Infographics Show for all the great content and keep up the amazing work.

  • sart your military bootcamp at august, then stationed at december in some asd, then you wont give a f*ck whats the weather outside.

  • Rethink Feynmann's equations and doddles, revisit Dirac and don't forget to imagine what Heisenberg and Schrödinger would do with the big question of time-space and matter duality that could explain if yes or no we have really dark matter or both. Don't forget your classics, Euler, Gauss, Laplace, and there, your head will glow hot.

    «Hey ain't that a bit cold today?»
    «The universe is in into its entropy, you only displace and transform energy that will later be halted in the confines of the universe, and once lost, losing mass forever, that's how it ends»

  • wear loose-fitting clothes

  • Can you last 30 seconds under a cold shower? Or 2 hours under the scorching sun in the summer?

    What do you prefer? ☀ ❄

  • I used to insulate agricultural barn attics every July and August for years. The roof deck would be anywhere from 120F to 140F and I add to that the Michigan humidity. I would be up there for 8 hrs a day: two 4hr periods.

    I got used to it. I would drink gallons of water a day and I got used to it.

  • i live in saudi arabia and in july the temprature here could rise up to 54 degree CELCIUS.

  • easy, just live in canada

  • The beginning makes me think of nakano

  • The coldest place that exist is my school…

  • Who even wants to stay in extreme temperature's, while you can stay on the couch and play spiderman ps4 lol?

  • As tough as a Korean granny you say… Well, depending on lifestyle, some old. People can be tougher than youngsters. My grandfather whose a farmer is stronger than me and I've never seen him complain on back pains.

  • Every one's Gangsta until AVERAGE JOE comes.

  • Is there any morons here who doesn't believe in global warming

  • Can the ice man survive radiation his immune system is really strong, but I think is still dangerous no matter what

  • Its pretty simple
    We should just evolve. Lol

  • I train my body for cold weather in summers and train for hot weather in winters

  • This would've helped a lot when I was stationed at Minot AFB…

  • I never put on the heaters in my house and I don't have airco

  • How to survive hot weather… Come to Singapore and stay here lol

  • So basically "Bear Grylls"

  • 37 decrees celcious isn’t hot at all

  • In the middle east its 40°C every day

  • Why don't we just take the cold and hot, and push it somewhere else.

    Just not into bigfoots forest

  • i cold not do that

  • Next video: how to train your virginity

  • And thats how Hamon came to be.

  • I live in a town where it usually never snows in the dead of winter, and when it does it snows like half an inch and then it melts the next day. About four years ago when the term "Global Warming" subtly shifted to "Climate Change", it snowed freaking seven inches. Not to mention the blizzards and record breaking snowstorms that left New York City without power for weeks. This year, it snowed again. IN LATE MARCH. AND IT DIDN'T MELT ALL THE WAY UNTIL THE END OF MAY! Not to mention that since carbon dioxide has been increasing, crop yield and life expectancy have also increased. Also, Fun Fact: Mars has about the same composition of Carbon Dioxide as Venus. So why is Venus 800+ degrees Fahrenheit and Mars is -250? It's a thing called atmospheric pressure. Cuz, u no, GLOBAL WARMING IS TOTALLY REAL

  • Me 2019 be like:
    "Who's Joe?"

    -me 2019

  • Klick here if ur a big fan of this channel

  • Wow! Really pushing the global warming agenda eh?

  • We've had The hottest Day ever In the Summer Vacation this Year. It was Horrible Because we never had Something like this Before.

  • Wim hof is one of the great dutch wonders of the world. As wel as johan cruijff.

  • I like a red hot bath then to walk into the garden with just a towel to smoke a joint in the snow

  • I live in Maryland so in one week this year it’s already been 90 Monday and 30 Thursday, so my body is used to being able to switch from the heat to the cold and how to adjust for it fast

  • I regularly take cold showers and people say my house feels like a freezer, both feel warm to me so it's weird. I lived up north and constantly hang out in the snow in winter or out on the coldest days of fall now I'm here in florida. I wear sweaters daily in the heat but I make sure to stay hydrated as of now I can walk just a little over 100° here in Florida without sweating until 25 minutes later.

  • I live in Arizona this is a regular summer hahaha 120 degrees f.
    Somehow I do super well in the cold as if I'm from somewhere freezing its wierd.

  • I’ve been having cold showers for 2 years now and it’s the best, although I live in Australia, I love the cold! Having a daily cold shower is like morphine for me, it makes me feel great, refreshed, happy, and alert, would recommend

  • How to survive extreme temperatures:

    you don’t

  • Every morning I eat scrambled eggs as breakfast (6 eggs to be specific) and I have dark chocolate powder mixed with dark roasted coffee and lots of sugar! It's a bomb, you should try it. You don't have to eat 6 eggs like me though! you can have 2 or 3 eggs, cup of oatmeal, a banana and your chocolat powder mixed with coffee.

  • My type of weather is 30-50’s.
