What to do if your face turns red when the weather gets hot

In life, some people have very thin stratum corneum, and their skin is more sensitive, especially when the skin is stimulated by cold or hot environment, they are prone to blushing. In winter, if they stay outdoors for a long time and suddenly enter a warm room, they will feel their face flushed and hot for a long time. So what should they do if their face turns red when the weather gets hot? Let me introduce you to

What are the reasons for blushing when exposed to heat?

1. The facial stratum corneum is too thin

Some people are born with a very thin facial stratum corneum, so it is easy to see the capillaries on their faces and the red bloodshot on their faces are more obvious. When this type of people are exposed to heat, the capillaries on their faces expand rapidly. Their pores are small and it is not easy to dissipate heat. Their blood vessels are less elastic, which can easily cause the skin's stratum corneum to become allergic, leading to blushing.

2. Better peripheral blood circulation

Some people have better blood circulation in the facial extremities, and they will blush when they move a little. When the face is exposed to heat, the capillaries continue to expand, peripheral blood circulation speeds up, and the face will be clearly manifested.

3. Excessive temperature difference

According to the principle of thermal expansion and contraction in physics, heat will cause the blood vessels in the human skin to dilate, while cold will cause the blood vessels in the skin to contract. When you're outdoors in the winter, your blood vessels quickly contract when they encounter cold air. Once you get indoors and the temperature rises, your blood vessels slowly begin to expand, causing the blushing phenomenon we see. However, frequently moving back and forth between extremely cold and hot places will cause the capillaries in the skin to lose their original elasticity due to repeated contraction and expansion. Generally in the early stages, facial flushing can recover immediately; once the capillaries are repeatedly dilated for a long time, they will lose their elasticity and may even be unable to recover, causing the face to remain red and develop patchy redness.
