And that's essentially what I'm trying to look into.

Is that a viable option?

Is that actually going to make any difference?

Or the other thing that we think might be really beneficial is just living an active lifestyle throughout your whole life.

Being physically active, trying to remain as fit as you can also helps you tremendously in the heat.

It can protect you quite a lot.

So I'm basically trying to weigh up, is it worth it to do these little short, intense acclimation protocols?

Or should we instead just be focusing more on trying to get people more active and seeing how that helps them in the heat as well?

There's been a lot of studies looking at exactly that, but there's no one answer really, because the problem with heat is it comes with a lot of other factors that also impact your survivability.

So things like humidity, pollution, how much access to water you have all impact the temperature you can survive.

But there's a metric called the critical environmental limit, which gives us an idea of what kind of temperature and humidity combinations people can survive.

And the way that that's assessed is you put someone in an environmental chamber and you slowly ramp up the humidity and you find the point that they can no longer maintain their temperature.

core temperature, and that's their critical limit.

And originally 35 degrees wet bulb temperature was proposed as kind of that critical limit, but recently quite a few studies have looked at those limits in people of different ages and doing different activities, and they're potentially quite a bit lower than that.

That 35 WITBOB limit, really it's probably somewhere more around 30 in a warm, humid environment, and maybe 25, 26, the numbers are variable in a hot, dry environment.

But that's at rest, so that's someone sitting down doing nothing,

So we're producing heat constantly and we have to get rid of that heat.

If you start doing higher levels of activity, you produce more and more heat.

And that's most commonly the biggest source of our heat stress is from us, from the activity we're doing.
