Frostbite can also be fatal. It is not recommended to rub your ears in hot water

Doctors point out that frostbite is a cold-related skin disease, which mainly manifests as localized, congested and inflammatory skin extremities. The temperature is low in winter, the weather is cold, and the skin is exposed to the cold and humid environment. When the skin of frostbite patients encounters cold, humidity, or sudden changes in temperature, the local arterioles contract, the arteries are paralyzed and dilated, the veins become congested, and the local blood circulation is poor, causing the disease. Be careful to prevent frostbite from getting infected. Once infected, it can easily lead to other diseases and even be life-threatening.

However, regarding the folk remedies such as soaking in hot water and rubbing the ears, doctors remind that after frostbite, you cannot immediately apply hot compresses or massage the frostbitten area to prevent aggravating local edema; soaking the affected area directly in hot water or roasting the affected area with fire will aggravate the frostbite. Rubbing the ears after frostbite is not advisable, because rubbing hard can cause local blood circulation disorders, making auricular pseudocysts and auricular perichondritis more likely to occur.

The treatment of frostbite is mainly to dilate blood vessels, promote healing and prevent infection. After seeing a doctor, the doctor will prescribe vasodilator drugs and comprehensive healing-promoting ointments for you according to the situation. Of course, prevention is worse than cure.

When you engage in outdoor activities for a long time, you should pay attention to keeping your hands, feet, face and ears warm, and be sure to protect against cold and water. To those parts that are prone to frostbite or where you have had frostbite before, you can apply protective agents such as Vaseline as a preventive measure. Never base it on whether you feel cold or not.
