Can drinking more hot water drive away the cold?

In the circle of friends, there is a health care method of treating winter diseases in summer: insisting on drinking hot water in dog days, not eating cold food and iced drinks, will force out the cold that has been deeply rooted in the bone marrow for many years.

In summer, many people are really not suitable for drinking iced drinks. For example, people who have a bad stomach are greedy for cold drinks, which will lead to a sharp drop in the temperature in the stomach, which is easy to cause bloating, indigestion, and even colic and diarrhea. Drinking hot water is a living habit of China people, but it is an exaggeration to rely on drinking hot water to discharge the cold accumulated in the body for many years. The main heat dissipation modes of human body are sweating and evaporation, and each evaporation 1 gram of sweat can take away 0.58 calories. When people drink tea or take a hot bath, "heat" stimulates the temperature receptors of the human body, causing the skin capillaries and pores to expand rapidly, greatly increasing blood flow and strengthening sweat secretion, thus effectively radiating the deep heat of the human body. The purpose of drinking more hot water in summer is mainly to sweat, expel the heat in the body, and reduce fever with heat, which is what Chinese medicine calls sweating, relieving exterior syndrome, relieving diarrhea and clearing heat. But this is just a way of fitness, and it doesn't mean that the cold in the body can be eliminated in a short dog days.

When eating cold food, you can match some warm food, such as wax gourd, and add some pepper before cooking to diuretic and detoxify.

Soaking feet with hot water can also dispel the cold, but the soaking time should not be too long. You can feel sweating after 10- 15 minutes. If you feel cold, you can also go to the hospital for scraping, cupping, dog days moxibustion and taking Chinese medicine to drive away the cold.

Remember the four disciplines in dog days.

Experts remind us to keep in mind the "three major disciplines" in dog days.

Avoid direct cold air blowing and long-term direct blowing, whether it is to turn on the air conditioner, blow the electric fan or enjoy the cool by the window. When you sleep at night, don't slit the doors and windows to prevent evil spirits from stealing wind. When blowing air conditioning, be careful not to blow directly at the cervical vertebra, and don't enter the cold air-conditioned room directly when sweating, otherwise it will cause disease; The air conditioning temperature should be appropriate, and it is recommended to be around 26 degrees Celsius; When blowing air conditioning, always open the window to ensure the convection and ventilation of indoor and outdoor air.

Independent activities, sweating, hot weather, many people like to stay indoors, do not want to go out. In fact, if you want to get rid of dampness and cold, in the final analysis, you should increase your yang, which is vigorous and natural cold does not invade your body. Therefore, it is necessary to go out properly in dog days, sweat and grow yang. However, exercise in summer should be moderate, not intense, otherwise the yang will be discharged with sweat, the qi machine will be injured, the metabolism of water and moisture will be affected, and the internal moisture will come out again, and finally the moisture will not be discharged. Especially people who are weak, can't stand the heat, and they can go out to exercise in the morning.

Pay attention to eat less cold and cold. In the dog days, the yang of the human body floats on the body surface, and the internal organs are cold. Drinking cold drinks and eating cold food at this time is equivalent to adding insult to injury. If friends who are physically weak and afraid of cold insist on not eating cold drinks in the dog days, then the cold in the body will drive away most of them, which can play the role of treating winter diseases in summer.

Protect the throat and the back of the heart. The throat and the back of the heart are the weakest parts of the human body and are vulnerable to cold. Protecting these two parts will help the body to buffer the cold.

Dog days teach you four tricks to prevent heatstroke.

Try to avoid long-term activities in the hot sun. It is best to wear light-colored loose clothes, a wide-brimmed hat or an umbrella when going out. Indoor ventilation can be maintained by air conditioning, but the air conditioning temperature should not be too low. After working in an air-conditioned environment for a period of time, you should take time out for heat-resistant exercise. Improve the adaptability of the body.

Exercise in moderation.

To reduce the amount of exercise in summer, it is best to do it in the early morning or at night when the weather is cooler. The venue should be in rivers and lakes, parks, courtyards and other places with fresh air, and the appropriate time is half an hour. Sweating too much during exercise, you can drink light salt boiled water or mung bean salt water soup appropriately. When the temperature reaches above 35℃, stop moving, stop braking and keep enough drinking water. At the same time, you should carry some conventional heatstroke prevention drugs with you, such as Ren Dan, essential balm, cooling oil and Huoxiang Zhengqi water.

You should replenish water every day. The simplest thing is to drink more boiled water or light salt water. Drink more salt water several times to prevent heatstroke. You can also drink fruit juice, yogurt and tea.
