What's the maximum and minimum temperature a human can survive?

A human can survive in temperatures from really cold to super hot, but not too extreme.

Imagine you're wearing a big puffy jacket on a really cold day, like when your breath turns into clouds and your nose feels like it's frozen. That’s about -40°C (-40°F), super chilly! If you stay outside too long at that temperature, your body can't keep warm enough, and you might get hurt. So, the minimum temperature a human can survive is around -40°C, like being in a giant freezer for a while.

Now imagine you're sitting on a hot sidewalk on a super sunny day, like when your feet feel like they’re burning from the heat. That’s about 55°C (131°F), like stepping into an oven! If it's that hot for too long, your body can't cool down and might get hurt. So, the maximum temperature a human can survive is around 55°C, like being in a giant toaster for a while.

So, humans are pretty tough, they can handle chilly freezers or hot ovens, but not both at once! A human can survive in temperatures from really cold to super hot, but not too extreme.
