There are several reasons, ranging from a common cold to more serious diseases.
1. If the head is cold, then the vessels of the head narrow, and the mucous membranes lose their protective properties. And this is just what the viruses around us are waiting for. There is no need to think that they cannot survive at sub-zero temperatures; for them to die, at least 70 degrees below zero is necessary.
2. If you constantly walk around without a hat in winter, this leads to a weakening of the immune system, which means that more harmful infectious diseases may begin to develop - tonsillitis, sinusitis, chronic runny nose, etc., which are fraught with various complications.
3. Meningitis is a disease that we first learn about at school and, fortunately, from the words that frighten us from our parents. This disease is an inflammation of the brain. It is infectious and quite severe. If you have hypothermia of the head, in rare cases you can get sick.
4. Otitis - inflammation of the ear is accompanied by severe pain, fever and discharge from the ears. It is dangerous because it can lead to damage to the eardrum and hearing loss. And ears that are not protected by a hat can simply get frostbitten, since there is no fatty tissue on the skin of the ears.
5. Hypothermia can also cause headaches due to the narrowing and then dilation of the vessels in the sinuses, or the flow of a large amount of blood into the brain. Sometimes they even occur when a person drinks cold water or quickly eats ice cream. Typically, such pain goes away within a few seconds, but can last longer.
6. Myositis of the cervical muscles is an inflammation in the muscles, which is characterized by persistent aching pain on one side, which intensifies during movement. Sometimes redness of the skin and fever occur.
7. Pain in the face or scalp. In the cold, small blood vessels that supply the nerves narrow, which causes trigeminal neuralgia, etc. Many people are familiar with the feeling when their hair “hurt” when combing.
8. Hair loss. Many people do not wear a hat to maintain their hairstyle. And this is very harmful to your hair. In cold weather, on an open head, the vessels that nourish the hair follicles narrow. Hair becomes weak, lifeless and begins to fall out.
There is also a banal allergy to cold, which causes a lot of inconvenience to those who suffer from it. Therefore, protecting your head with a hat in winter is simply necessary, no matter how much you want it. Choose a light, comfortable model and hats for yourself and wear it in cold weather to make it easier to endure winter.
