Do you wonder why your skin feels so tight in winter? Why is it more sensitive to a change in temperature, whether cold or hot, such as after a bath, for example? Here we will answer all your questions by giving you all the mechanisms causing this phenomenon. You will have all the keys in hand to know the reactions of your skin to cold and heat. So, shall we explain to you?
Dry indoor air
Indeed, winter often rhymes with heating. The latter dries out the ambient air of the house which will ultimately absorb the moisture from the skin. Remember to put a small glass of water on your radiator: this will increase the ambient humidity.
The thermoregulation of the body
Thermoregulation, as its name suggests, corresponds to the fact that the body always tries to maintain the same body temperature. In case of severe cold, the body will produce chemical molecules causing vasoconstriction of superficial vessels (contraction of small vessels) and vasodilation of deep vessels in order to ensure a constant temperature for vital organs.
However, this superficial vasoconstriction causes less blood flow and less good elimination of toxins. The skin is therefore less hydrated, with more toxins not eliminated.
Now you know everything about how your skin reacts in winter! In the next article, we will give you the routine to adopt to best experience these temperature variations.
