Do people who freeze their ears in winter freeze their ears every year?

In winter, many people's hands, feet and ears are easy to freeze, resulting in frostbite, pain and itching, and some even fester and infect. Besides the cold weather, there is another important factor, which is closely related to blood circulation. In winter, people are less active, and their blood circulation and metabolism are slow, especially if there is congestion on the back of their hands, ears and feet, which will cause local tissue necrosis and chilblain.

Guiding opinions:

In order to prevent frostbite, besides keeping warm, the best way is to rub and massage hands, feet and ears frequently, and insist on washing hands with cold water, washing face or appropriate sports activities to speed up blood flow. When working outdoors, be sure to eat enough, wear warm clothes and make all kinds of preparations to keep out the cold, such as wearing gloves, hats and cotton shoes. Keep clothes dry, ears, face, hands and feet, which are easy to freeze.
