How does frostbite form?

1 Cold weather

Cold weather is the main cause of chilblains. As the temperature drops, the body's blood circulation slows down. In particular, it takes time for the body to adapt to the temperature. If you don't pay attention to keeping warm, you will easily develop chilblains. Common frostbite locations include exposed hands, ears, and feet.

2. Humid environment

If the environment is humid in many places, the cold to the body will increase, which will affect the normal vasoconstriction and dilation functions and promote the formation of chilblains.

3. Sweaty skin

People with moist and sweaty skin are more likely to develop chilblains. This is because people with moist and sweaty skin dissipate heat quickly, and their skin is prone to lower local temperatures and slower blood circulation.

4 Weak physique

People with a weak physique are also less resistant to cold, their blood circulation is poor, and they are more likely to develop chilblains. In addition, for people with heart and blood vessel diseases, the body's blood circulation function is poor, and the local skin is less adaptable to cold. It is easy to form chilblains when stimulated by cold.
