What if it's too cold?

Pay attention to keep warm when it is too cold: keep warm at the core, add more iron in winter, do some warm-up exercises, and raise yang to avoid being afraid of cold.

1, the core keeps warm.

As the temperature drops, there are tricks to increase clothes to keep warm. Keep your lower limbs warm and your whole body will be warm. Your hands and feet are cold. Try not to always use a hot water bottle or keep the baby warm. You can soak your feet for 20 minutes several times and massage the soles of your feet. When you feel cold at home, you can put on a warm vest and foot covers to wrap your ankles to keep your body temperature in the core area.

2. Add more iron in winter.

Iron participates in the synthesis of heme containing iron in human body, which improves the oxygen carrying capacity of blood. Therefore, the oxygen supply in peripheral tissues of people with iron deficiency will be reduced, and the energy metabolism of human tissues will be blocked, and naturally they will feel cold due to insufficient heat production. Therefore, we should pay more attention to supplement iron-rich foods, such as lean meat, fish, animal liver, egg yolk, beans, celery, mushrooms, black fungus and so on.

But the cholesterol in animal liver and egg yolk is high, so you can't eat too much. You can eat it once a week, and fried celery, sliced mushrooms and cold fungus can often appear on the dinner table. While supplementing iron-containing foods, we should also eat more foods rich in vitamin C to help the body absorb iron.

3. Do some warm-up exercises.

In winter, many people go home and don't want to move, get into bed or nest on the sofa, which is wrong. Slow blood circulation will make you feel colder. You can do some warm-up exercises at home, such as yoga, which is soothing, light and slow, can promote blood circulation and is suitable for home. Do some warm-up exercises in bed before getting up every day.

4, yang, to avoid cold.

Chinese medicine mentioned that Yang Can promoted the operation of five internal organs, which was the source of human warmth. When the yang is insufficient, it is easy to be mentally exhausted and afraid of the cold. Adequate sleep can supplement the deficiency of yang. Adequate sleep and rest will give your body enough physical strength to resist the cold and pressure from outside. Especially in winter, you should go to bed early and get up late, sleep at night 10, and get up after the sun comes out, so as to avoid catching a cold in the morning and reduce the risk of heart disease and stroke caused by rapid contraction of blood vessels caused by excessive temperature difference in patients with chronic diseases. Try not to stay up late.

The wrong view of keeping warm in winter

1, cover your mouth

If you put a scarf around your mouth, tiny wool fibers and bacteria will be inhaled into your lungs when you breathe, causing respiratory infections. There are still many people who wear masks to keep out the cold, but if they wear masks all day, the mucous membranes of the nasal cavity and the whole respiratory tract will not be exercised, and their ability to cope with cold air will be artificially weakened. If they catch a slight cold, they will easily catch a cold.

2, drink cold

People will feel warm skin after drinking because the peripheral blood vessels in the skin, such as microvessels, are widely expanded and heat is emitted through the skin. However, alcohol, after all, is different from protein, fat, carbohydrates and other energy substances, and does not produce much heat. Therefore, after drinking, due to the abnormal heat dissipation of the body, a lot of heat will be lost, and the mild feeling will eventually be replaced by cold. Therefore, drinking can't keep out the cold, it will only get colder and colder.

Step 3 close the doors and windows

Sleeping with doors and windows closed in winter does reduce air convection and increase indoor temperature, but the resulting air circulation is more harmful. The human body produces more than 500 chemicals during metabolism, of which 149 are excreted from the respiratory tract. Therefore, the air contains a lot of bacteria, viruses, carbon dioxide and dust particles, which affect the respiratory tract. Therefore, people who close the window and take a nap often suffer from colds, coughs, pharyngitis and so on.

4, sleep with a hat

When people sleep with their heads covered, they constantly exhale carbon dioxide, which is completely concentrated in the narrow space formed by the quilt, and the oxygen concentration is constantly decreasing, while the human body naturally emits damp heat during the whole sleep process, making the air in the quilt quite wet and dirty. If you sleep with your head covered for a long time, your brain will be seriously deprived of oxygen, and you will have no spirit when you go to work the next day, and people will become dizzy.
