One of the 
skin’s main tasks is to 
protect the body from external stimuli. It envelopes us like a coat and ensures that we are not immediately hurt under pressure or impacts.
It also warns us of danger such as high levels of heat or extreme cold by means of its sensors using pain or itching.
As a temperature regulator, the 
skin is also responsible for keeping a constant temperature within the body. When it is hot, the circulation of blood in the vessels increases and heat is released. If this is insufficient, the 
skin sweats and 
cools the body down. If it is cold, the opposite happens: the 
skin pumps less blood through its veins in order to keep the warmth within the body. This is why when it is cold, our hands and feet are the first to freeze.
Our 
skin also works to 
protects us from 
sunlight. If you go out in the 
sun’s rays, the 
skin can develops a thicker rough layer and dark pig
mentation – tanning. Both act as a filter that allows the 
harmful UV rays to penetrate the 
skin to a limited extent. Damage caused by 
sunlight can be partially 
repaired by the 
skin itself, however, it needs time to do it. To support the 
natural protective functions of the 
skin against 
sunlight, when spending extended times in the 
sun you should always use a 
sunscreen with an adequate 
sun protection factor (SPF).
