Winter is coming, and the temperature of the water we bathe in is getting hotter, isn't it? After all, a hot bath relaxes, brings comfort... and harms the skin!
Yes, it's true. According to dermatologist Irene Baldi, hot water alters the skin's balance and affects the skin barrier, which is a kind of "coat" that protects the skin from problems like bacterial proliferation, infections, and dehydration.
“As a result, the skin becomes dehydrated. Thus, the skin understands that it needs to produce even more oil, which can cause pore dilation,” says the doctor. According to her, those who have dermatitis (and already have an alteration in the skin barrier) should avoid hot water because the problem also worsens with high temperatures.
“Meanwhile, cold water has the power of vasoconstriction, which helps reduce redness and irritation of the skin and the size of the pores. Low temperatures also activate blood circulation, giving your skin a natural glow,” recommends the doctor.
Dermatologist Karina Mazzini also agrees that no one is obligated to take cold showers in winter, but it doesn't have to be too hot, due to several factors: "Using very hot water on the body and face harms hydration and removes the skin's natural protection. Hot water dries out the skin because it affects the mantle-lipid layer, which is responsible for the smooth texture. It can cause dermatitis, depending on the degree of dryness. On the hair, hot water increases the production of sebaceous glands, leaving the strands oily and causing dandruff. On the face, it opens the pores and also makes it oily," says Karina.
So, avoid very hot showers! "Just use a milder temperature in the shower; instead of the 'winter' setting, use the 'summer' option," suggests Karina.
