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

100 thoughts on “How To Train Your Body To Survive Extreme Cold and Heat – Science Experiment

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

    What do you prefer? ☀ ❄

  2. 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.

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

  4. 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

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

  6. 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

  7. 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.

  8. 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.

  9. 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

  10. Well, I do know that I like to travel a lot. But I’ve never been to a place s cold as Iceland in the winter. (I know, Iceland is green, and Greenland is ice. But in the winter, they’re both ice.) anyway it was freezing there, no matter how many layers i had, especially my fingers and toes. I do remember the wind, that was also freezing, pushing us so much that if I was on ice, I started to slide. It was very fun. The northern lights were beautiful. And while hunting for the lights, we saw a wild Arctic fox. But there also was extreme heat. We wore ski suits with many layers under. And we went to a lava show, where they pour lava into a contained spot in the room. I was plenty of feet away, and felt like I was back at home, in Georgia under the merciless sun. I’m truly grateful of my experience and hope to do it again!

  11. I'm from Australia and always thought Sydney winters were miserable until I spent a winter in Iowa in the US. Never again.

  12. I was in the coldest Macy’s thanksgiving day parade in history and caring a metal instrument you already know that it was freaking cold. We were gettin frostbite, people were crying, It was a mess.

  13. "Save a fortune on your water bill"??? You're going to use the same amount of water you idiot. Hot water is determined by the hot water heater in your house. So you'll save on your gas bill, not the water bill.

  14. Dude where I live it’s currently 44 degrees Celsius 2 hours in a desert sun is very easy we live in a city that’s in a desert

  15. I was in Kuwait for months and the temperature would go up to 113 degrees all the time. Tbh the dry heat wasn’t that bad at. I also got there in the winter so it wasn’t
    That bad so my boy had a lot of time to get used to the change in climate.

  16. For the cold i just pull my sleeves up and let the cold envelop. Its helpful for when texas winters play.
    For the hot…. uhhh…be calm and wear as many things. For some reason me wearing alot of stuff slows down the heat from getting to my body

    This is incorrect, I’ve been living in Australia my whole life, the only animals you ever really see are Roos and dogs and a few redback spiders every now and then. The animals will only attack you if you mess with them such as chatting up their wife, or went in their territory.

  18. i live iraq 🇮🇶 the temperature is 50 degrees celceus in the summer and i don’t mind it but i cannot handle the cold

  19. Brad Pitt has trained himself to handle extreme temperature swings. For example, he was married to Jennifer Aniston and she is totally hot. Then he dumped her and married Angelina Jolie, and that b—-h is totally cold.

  20. The hyperventilating is not necessary. I've recently practiced the cold exposure without it, for about 6 months daily, and I can say that it is superfluous.

    Holding your breath is the key. Which by the way is not oxygen deprivation panick. The body doesn't respond to oxygen deprivation. In fact, it responds to the buildup of co2.

    The hyperventilating only appears to aid this process because it depletes your co2 and thus delays the panick reaction.

    But what actually matters is building your resistance to c02, and the hyperventilating exercise does not directly improve this.

    It has an indirect mental effect because depleting co2 increases your ability to hold your breath dramatically and this will affect your assumption of what is possible.

    But ultimate you must train the co2 resistance. So depleting co2 through hyperventilating is not necessary.

    It does release adrenaline, but I have had the same ability of cold resistance without hyperventilating.

    I'm taking 25-30 minutes submerged in flowing water 8 degrees celcius. Flowing water saps your heat much more due to the inability to heat the water around your skin.

    25 minutes a day, sometimes several times is quite intense as far as the average wim hof practitioner goes.

    I have not attempted anything more severe in terms of temperature and length because it's not easy to get that cold in the topics.

    It may be that extreme feats do necessitate the hyperventilating.

    However, I enter the water calmly. Barely breathing in fact. While others sit there hyperventilating, and I stay in longer and calmer.

    I inspire you to try my method, to see for yourself how you can replicate the cold resistance.

  21. Surviving the cold: you will need to undertake years of intense meditation and slowly ease into colder and colder conditions.
    Surviving the heat: lol just drink water

  22. If I try to breathe in too much, I feel my lungs push up against my ribcage, and sternum..

    Then, my lungs shake around and automatically exhale!

  23. I once travelled to Pahalgam, Kashmir, India in June and put my feet in a running cold stream, had to take it out after 5 seconds cause my feet got numb

  24. It's great that you dont put little political comments in your videos. I hate when people do that. Thanks so much for not doing it!

  25. My advice when in extreme temperatures:
    When in Heat: Be glad that you are not freezing to death.
    When in Cold: Be glad that you are not sweating to death.
    Both temperatures can be your best friend and your worst enemy for staying alive.

  26. For a second I was like yeah I should learn how to do that! Then I remembered my temperature disregulation is caused by auto immune disease to the nervous system. Nevermind.

  27. lol arizona experiences those extremes too like australia it can get up to 115 degrees Fahrenheit in the summer and can routinely get below freezing in the winter (like 28 degrees F)
