[**Doctor talks to you: How can chilblains be prevented?]】
Chilblain is an inflammatory disease that often occurs in exposed areas of the body and at the ends of the limbs.
The occurrence of chilblains is mainly associated with cold and dampness. In winter, when the temperature continues to be very low, or when the temperature changes suddenly, the exposed parts of the human body will cause vasospasm and contraction in the low temperature environment due to the reflex of the nerves, and the local blood flow will be reduced.
In a clammy, cold environment, chilblains are more likely to occur. Or people who have malnutrition, chronic wasting diseases, immune-related diseases, or vascular-related diseases are also prone to chilblains.

You can also try soaking your hands and feet with hot and cold water alternately, which also has a certain "adaptation effect".
