Sweat Is Why We’re The Top Of the Food Chain
Humans are mammals. Mammals have this cool property: they’re warm blooded. This means we can regulate our temperature without sunning ourselves on a rock like some doofus snake. When we’re hot, we sweat. That sweat evaporates, cooling us off. Pretty simple. But humans have one of the most efficient cooling mechanisms in the animal kingdom. With no fur, we sweat through our skin, giving us a massive surface area to chill out with.
Our furry buddies aren’t so lucky. Back in hunter-gatherer times, humans chased animals for hours and hours (sometimes days) until those animals dropped dead from heat exhaustion. In fact, some groups still practice this ancient hunting technique today. Our efficient sweat system is a key reason why we’re able to dominate creatures that are faster, stronger, and way more claw-ier than ourselves.
