Frostbite on the ears in summer is clinically rare, but there are also long ones for the following reasons: First, frostbite is not completely cured in winter, and may form again once the auricle is locally stimulated by wind or cool water after entering summer. Secondly, patients usually lack exercise, which leads to poor circulation throughout the body, such as in the ears, and poor peripheral circulation can easily lead to local tissue ischemia and hypoxia, which can also lead to frostbite. Third, in the summer, local extrusion of the auricle or local cold air stimulation, rain or sudden changes in temperature, temperature differences can also lead to changes in frostbite in the ears. Frostbite in the ears clinically: first, pay attention to keeping warm; second, often rub the auricle with your hands to promote blood circulation in the auricle, and if the lesion is serious you can also apply frostbite cream appropriately, and usually take more vitamins.
