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 pigmentation – 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)
