What would happen if the human body was not covered with skin?

Let’s consider two main functions of human skin.

The first is defensive. Indeed, the skin, consisting of several layers, covers the entire surface of the body of the body, thereby hiding other organs.

The second function is metabolism. It participates in various metabolic processes and also synthesizes vitamin D.

From this we can conclude that in the absence of a person’s skin, the risk of infection or diseases of the body, damage to internal tissues and organs will increase. But also, the metabolism will be somewhat slower.
