What is the reason why the skin turns red when it is hot?

There are three main reasons for blushing when it is hot. The first one is caused by the thin cuticle of facial skin, the second one is caused by the excessive temperature difference, and the third one is caused by the overheated outside weather and the accelerated blood circulation.

Proactive suggestion

It is recommended to avoid going out when the weather is hot outside. If you must go out, do a good job of sun protection, apply moisturizer and sunscreen, and moisturize your face in your life.

Matters needing attention

Don't work in high temperature environment for a long time, protect the skin on your face, don't watch electronic products for a long time, and don't turn off the lights and watch your mobile phone before going to bed.
