What are the misunderstandings about winter health care

Winter is coming soon. Many people hate winter very much, because in addition to the cold, winter also makes people feel that this season is lifeless. Not only is the temperature low and the humidity low, but it also has a certain impact on people's physiology and physical condition. Do you know about the misunderstandings about winter health care? Let's take a look at what those misunderstandings are.

Wear a mask to protect against cold. The nasal mucosa is rich in blood vessels and cavernous vascular networks, and the blood circulation is very vigorous. When cold air is inhaled into the lungs through the nasal cavity, it is generally close to body temperature. The human body's ability to withstand cold should be enhanced through exercise. If you rely on wearing a mask to keep out the cold, it will make the body more delicate and more susceptible to colds. 

Cover your head and sleep. Covering your head in the quilt will make you feel warmer, but the oxygen in the quilt will become less and less, while carbon dioxide and unclean gases will accumulate more and more. Therefore, people who sleep with their head covered will feel groggy and weak after waking up. Wash your face with hot water. In winter, the sweat glands and capillaries on the human face are contracted under the stimulation of cold air. When it encounters hot water, it expands rapidly, but after the heat dissipates, it returns to its low temperature state. The expansion and contraction of capillaries can easily cause wrinkles on the face.

Drink to keep warm. After drinking, you feel hot all over. This is the result of alcohol prompting the body to release its original heat energy. After the effect of alcohol wears off, a large amount of heat is dissipated from the body, causing goose bumps all over the body, leading to a feeling of cold after drinking. 

Frozen hands and feet are roasted over fire. In winter, our hands and feet are exposed to the elements for a long time, which causes blood vessels to constrict and blood flow to decrease. At this time, if you use fire to bake it immediately, it will paralyze the blood vessels and lose their contraction force, causing arterial congestion, capillary dilation, increased permeability, and local congestion. Mild cases cause frostbite, while severe cases cause tissue necrosis. Therefore, frozen hands and feet can only be rubbed gently to slowly restore them to normal temperature.

Scratching itchy skin. When you feel itchy all over your body due to dryness in winter, you must not scratch it with your hands, otherwise it is easy to scratch the skin and cause secondary infection. The prevention and treatment methods are to drink more water, eat more fresh vegetables and fruits, eat less sour and spicy foods, and drink less strong alcohol. Take a bath and change your underwear frequently. If the itching is severe, you can take drugs such as chlorpheniramine and phenergan, or apply some calamine lotion or skin relaxing ointment for treatment.

These are the introductions to the misunderstandings about winter health care. The arrival of winter has made many people pay attention to the issue of health care. Correct health care knowledge can better regulate the body, but incorrect common sense will be counterproductive. Not only will you not get good health protection, but it will cause greater harm to the body. Therefore, you must choose the correct health care knowledge.
