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.
