Is cold feet harmful to your health in winter?

Feet are the second heart of human body, so it is very important to keep feet warm.

The temperature is very low in winter, so children's feet need to pay special attention to keep warm. People's feet are far from the heart and have less blood supply. If they catch a cold, the capillaries will spasm, further reducing blood circulation.

Children's feet have less surface fat and poor heat preservation ability. Standing on the ground in winter will emit a lot of body temperature, which will reduce the temperature of the foot, thus increasing microvascular spasm, blocking blood supply and further reducing the temperature of the foot. This will not only lead to chilblain, but also affect internal organs. Adults can also cause stomach pain, lower abdominal pain, irregular menstruation, impotence, low back pain, leg pain and other diseases.

In addition, once the foot catches cold, it can reflexively cause the microvascular contraction of the upper respiratory mucosa, slow down the cilia movement and weaken the body's resistance, so the pathogenic microorganisms lurking in the nasopharynx and newly invading will take the opportunity to multiply in large numbers, causing diseases such as colds and bronchitis.

The key to keeping feet warm is exercise and wearing shoes and socks. Children had better wear cotton socks and shoes in winter. Winter socks can be worn in wet and cold areas, because humidity can aggravate the temperature distribution of feet, leading to microvascular spasm, blocked blood supply, tissue necrosis and frostbite. Anti-frostbite socks can prevent microvascular spasm and keep blood circulation smooth. In addition, socks, insoles and cotton shoes worn in winter should also be dried frequently. Shoes and socks are dry to keep warm.

People draw an experience from practice, that is, "cold head and hot feet make you healthy."
