When it is very cold in winter, my hands and feet are cold, and sometimes my face is blue with cold. When it comes to winter, I feel worried. What should I pay attention to?

There are many unhealthy living habits in winter, which are often mistaken for correct by some people.

Wear a mask to prevent colds.

There are abundant blood vessels and spongy vascular network in the nasal mucosa, and the blood circulation is very strong. When cold air is inhaled into the lungs through the nasal cavity, it is generally close to body temperature. The cold tolerance of human body should be enhanced through exercise. If you wear a mask to keep out the cold, it will make your body delicate and more likely to catch a cold.

Sleep with your head covered.

Burying your head in the bed will make you feel warmer, but the oxygen in the bed will be less and less, and carbon dioxide and unclean gas will accumulate more and more, so people who sleep with their heads covered will feel groggy and exhausted after waking up.

Wash your face with hot water

In winter, sweat glands and capillaries contract under the stimulation of cold air. When it meets hot water, it expands rapidly, but after releasing heat, it returns to the state at low temperature. Such capillary contraction is easy to cause wrinkles on people's faces.

Drink to keep out the cold.

After drinking, I feel warm all over, which is the result of alcohol prompting the human body to emit primitive heat energy. After drinking, the body releases a lot of heat energy, which makes people get goose bumps all over, leading to a cold after drinking.

Freeze your hands and feet and bake them with fire.

Exposing hands and feet for a long time in winter causes blood vessels to contract and blood flow to decrease. At this time, if it is baked with fire immediately, the blood vessels will be paralyzed, lose their contractility, and there will be arterial congestion, capillary dilation, enhanced permeability and local congestion. Mild frostbite, severe tissue necrosis. Therefore, frozen hands and feet can only be gently rubbed to make them slowly return to normal temperature.

Scratch itchy skin with your hands.

When you feel itchy all over because of dryness in winter, don't scratch it with your hands, otherwise it will easily scratch your skin and cause secondary infection. The prevention method is to drink more water, eat more fresh vegetables and fruits, eat less spicy food such as hot and sour, and drink less. Take a bath frequently and change your underwear frequently. Those with severe itching can take chlorpheniramine, phenamine and other drugs, or apply calamine lotion or soothing ointment for treatment.

Three steps to prevent colds in winter

When the weather is cold, people have more chances to catch a cold. The three steps to prevent colds are summarized as follows:

Step 1: do asana breathing to prevent catching a cold. When going out for activities, sometimes because of the sudden change of weather, the clothes worn are not enough to keep out the cold. At this time, you can't tighten your body together, because the tighter the cold, the easier it is to invade. Instead, you should do asana breathing immediately. The method is to raise your hands to your abdomen and take a deep breath. When inhaling, you should inhale your limbs and expand your arms slightly, which can enhance your cold resistance and not feel cold.

Step 2: Cold rub the back of the neck. If cold air has invaded the body and you feel cold all over, rub the hairline at the back of your neck with your palm, and each hand rubs 100 times, so you can generally sweat, and you can avoid catching a cold by sweating.

Step 3: Rub the cold with onion, ginger and salt. If you already have a cold feeling, such as sticky saliva and uncomfortable feeling all over, before going to bed that night, mash 20 grams of scallion, 20 grams of ginger and 3 grams of salt powder, wrap them in gauze, wipe your chest, back, palm, rib fossa, elbow fossa and foot heart in turn, then cover the quilt to sleep, and get up early the next morning to sweat a little. But pay attention to cold protection within two days to avoid duplication.

Winter life taboo

Avoid licking your lips often.

Some people think that chapped lips can be licked with the tongue, but the result is just the opposite. Saliva is secreted by salivary glands and contains amylase and other substances, which is relatively viscous. After licking your lips, it seems to be covered with a layer of paste. When the water evaporates, the lips will be drier. If your lips are dry and uncomfortable, apply lip balm without pigment and fragrance.

Avoid using pure glycerol.

People usually use glycerol containing 20% water. If pure glycerin is used, its water absorption capacity is too strong, which will absorb the moisture in the skin, but it will make the skin drier.

Avoid wearing too much.

If you wear too much and too thick, the blood vessels in the skin will expand, and the blood flowing to the skin will increase, thus increasing heat dissipation. This reduces the body's ability to adapt to changes in external temperature.

Suggestions on winter health care for office workers

Sitting in front of the computer for a long time in a turtle neck, do you feel that your neck and shoulders are more sore than usual and you have difficulty breathing? This is called "high disease". People who sit in offices in winter should pay special attention. If you are afraid of cold, don't wear high-necked underwear or sweaters that are too high and too tight, otherwise it will easily oppress the carotid artery and cause insufficient blood supply to brain tissue. How can your work efficiency be high?

It is easier to catch a cold when you go out from an office with adequate heating or air conditioning, so don't close the doors and windows all day because it is cold outside. Always open the window to keep the air circulating. As long as you don't delay going to work, walk as many steps as possible and exercise your cold tolerance in the cold air.

Is there a good hand cream in the desk drawer? I often touch the keyboard and shake hands with visitors at work. I think you should wash your hands more often than at home, but I often see female colleagues rushing to the canteen without washing their hands at noon, saying that they are afraid that washing their hands will cause "burns" to their skin. Very simple, a hand cream can make you pay attention to hygiene and maintain your jade hands at the same time.

Looking out of the office window in winter, flowers and trees are withered, and rain and snow are falling. Touching the scene makes people feel depressed and depressed. However, smart people will try their best to stay calm, cheerful and optimistic, listen to music during breaks and do some housework that interests them at home, such as decorating the room. I don't know when you are in a quiet mood.
