What is skin for?

Our largest sense organ# 195 What do we need skin for?

You probably haven't given much thought to your skin yet, have you? It's just there. It's worth taking a closer look - and that's exactly what we're doing in this episode. In truth, the skin has tons of superpowers! Fancy a small selection?

1. The skin is our protective cover

It protects us from intruders, bacteria and germs. And if we could pull it off and spread it out, it was as big as a picnic blanket. The structure and color of the skin are a little different for everyone.

2. The skin is our air conditioner

It helps us not to overheat or cool down. If we are too hot, we sweat. The water evaporates and cools our organism. The skin can also absorb light and convert it into heat.

3. The skin is the boundary layer and point of contact

We use them to perceive the touch of our environment and our fellow human beings and decide whether they are pleasant or unpleasant. Without our skin, cuddling and caressing would be inconceivable. We wouldn't feel the warm sea breeze, the fluffy blanket or the warm hand of grandpa.

4. The skin is our warning system

... and our largest sense organ. With its receptors, it measures every stimulus that affects our body surface and reports this to our brain. So nasty crawfish don't stand a chance! By the way, the skin is most sensitive on the fingertips. With them we can even record how many legs an insect has.

5. The skin can renew itself

So if that's not a superpower: The skin has several layers, a bit like an onion. Except that with us the top layer renews itself! On average, a person loses 50 kilograms of skin in the course of a lifetime. That's as much as a baby rhino weighs.
