Experts say
Fumigating vinegar can not prevent colds, but may stimulate the respiratory tract.
Can smoked vinegar really disinfect and prevent colds? The reporter interviewed Chen Hong, deputy chief physician of Chinese medicine cancer treatment center of Chongqing University Cancer Hospital. She said that acetic acid has a certain bactericidal effect, but the acetic acid concentration of vinegar is very low, so smoked vinegar naturally can not achieve the effect of disinfection and sterilization, nor can it prevent colds. On the contrary, smoked vinegar generally has a strong irritating smell, and may also stimulate the respiratory tract, especially respiratory diseases, such as chronic bronchitis, bronchial asthma, emphysema, etc., and may also induce diseases.
In winter, people think it is very cold outside, so they close the doors and windows at home to ensure the indoor temperature and prevent colds. In fact, this is also a misunderstanding. Chen Hong said that the human body will produce a large number of chemicals in the process of metabolism, and more than 40 kinds of chemicals are discharged from the respiratory tract. If the doors and windows are always closed, there will be a lot of bacteria, viruses, carbon dioxide and so on. It's easier to catch a cold in the air without ventilation. Therefore, the average family should open the window at home in the morning and evening, and the ventilation time should be at least half an hour at a time. In addition, to prevent colds in winter, drink more water, exercise more, and change clothes immediately after exercise.

Experts teach you to keep fit from head to toe in winter.
In winter, we should not only prevent colds, but also pay attention to health. How to preserve one's health is correct? In this regard, Wang Wei, director of the Chinese Medicine Cancer Treatment Center of the Cancer Hospital affiliated to Chongqing University, has some suggestions:
1. Pay attention to the windproof of the head, but don't keep it too warm. Don't lie in a windy place when sleeping, especially where your head can't leak air against the doors and windows, so as not to catch a cold and hurt your brain. After washing your hair, dry it in time. In addition, the head should not be too warm, and the blood flow in the head can completely regulate the body's heat, especially for children. Don't overprotect and exercise the body's cold resistance. For middle-aged and elderly people with low immunity, they can wear hats and scarves with moderate thickness when going out.
2. Eat more nutritious food and less salty food. In winter, the climate is dry, and the evaporation of water from human skin mucosa is accelerated, so dry skin, dry nose, dry lips, sore throat and other autumn dryness phenomena can be achieved through diet therapy, such as tremella, lily, pear, sugarcane, coix seed, milk, cabbage, radish and so on. In addition, try to eat less salty food and drink more water in winter.
3. Do not soak your feet for more than 20 minutes, and the water temperature is about 45℃. Soaking feet can stimulate foot acupoints, thus relaxing body and mind, helping to relieve physical fatigue and improve sleep quality. But soaking feet for a long time is not as long as possible. Soaking feet for a long time will cause dizziness, dry skin and other adverse reactions. Generally, soaking feet does not exceed 20 minutes at most. It is advisable to have red instep and sweat slightly, and it is best not to sweat.
The water temperature for soaking feet in winter can be kept at around 45℃. The water temperature is too low to achieve the desired effect. If the water temperature is too high, the human body cannot bear it. If the skin of diabetic foot is not sensitive, the water temperature can be reduced appropriately to avoid scalding. In addition, people with heart disease, cardiac insufficiency, low blood pressure and frequent dizziness are not suitable for long-term foot bathing. Hot water causes systemic vasodilation, which may cause ischemia and hypoxia in important organs such as heart and brain, and increase the risk of illness.
4. Pay attention to neck, shoulder and waist maintenance. When sleeping, the height of the pillow should be straight to the neck. Don't read or watch TV while lying down. Avoid working with your head down for a long time. It is best for sedentary people to get up within 2 ~ 3 hours 10 ~ 20 minutes, or hold their heads up and stretch their necks every half hour to do chest expansion exercises. When sitting for a long time, you can put a small pillow on your waist to keep the normal physiological curve of the lumbar spine and reduce the damage to the intervertebral disc.
