Therefore, in the cold season, we should pay special attention to the occurrence of hypothermia in the elderly. Cold weather will constrict blood vessels in the skin. Continued low temperature will cause skin redness, swelling, numbness, pain and other changes, and some people may even have skin allergic symptoms and urticaria.

The sudden drop in temperature will induce the aggravation of asthma and other diseases.
