What is the reason why the skin color becomes very bad when the weather is a little cold?

The skin color becomes very bad because the cold weather slows down the blood circulation.

Suggestion:

One: Keep warm. Besides wearing warm clothes, remember to wear hats, scarves, gloves and breathable soft and warm shoes. It is important to keep the head, face, neck and hands warm, because the head and neck heat dissipation accounts for 30% of the whole body heat dissipation.

Two: more sunshine and more activities: in addition to keeping out the cold, it can also reduce blood viscosity and promote blood circulation.

Three: outdoor activities must pay attention to keep warm, and try to choose a time with higher temperature and better air.

Four: avoid wearing too tight socks and underwear, so as not to affect the arterial blood flow of limbs.

Five: Moderately supplement calories to avoid hypothermia caused by hunger or hypoglycemia. Eat less oil and sweets, eat more fruits and vegetables to supplement vitamin C, and improve blood viscosity.
