How to prevent colds in winter?

Everyone knows that colds and fever are high in winter, especially many children or adults with weak physical resistance. Everyone knows that the current environment is extremely high in pm2.5. In addition, the indoor temperature is extremely high, and it is extremely cold outside. So many people catch a cold. So how should we prevent colds? This problem is of particular concern to many people. Then let's look at Bian Xiao's skills.

1 outdoor sports

In winter, the temperature drops, many people seldom go out, and the amount of exercise is obviously reduced. Such a move is often not conducive to the prevention and treatment of cold diseases. Therefore, even if the weather is cold, outdoor physical exercise should be persisted, but it should be moderate. Take an outdoor walk in the morning and evening, breathe fresh air, enhance blood circulation, improve physical fitness and improve immune function. In addition, outdoor activities can receive more sunlight, which is beneficial to the human body to synthesize more vitamin D, which is not only beneficial to bone health, but also can enhance the human body's resistance, reduce respiratory infections and effectively prevent colds.

2. Diet and health care

Eat raw green onions: I don't know if you have heard the saying: 7 slices of green onions, 7 slices of ginger, radish and cabbage are safe and healthy. I have never forgotten what my father said since I was a child, especially in this cold winter. If you eat these foods, you can prevent diseases. In this dry season, eating radish and cabbage can also remove the fire, and friends who like to eat green onions with sauce are also good appetizers.

Always replenish water: the climate in winter is very dry, and it is easier to get angry indoors without humidification equipment, so water is an essential thing for us. Supplementing enough water every day can not only prevent colds but also reduce diseases.

3. Open the window for air.

It is cold in winter, and many people are reluctant to open the window for air, but this behavior hides a huge crisis. Cold is mainly spread through the respiratory tract through air droplets. If the air is not circulated, it will easily lead to the existence of a large number of viruses indoors, so people are particularly prone to catch a cold, so ventilation is the best disinfection. The circulation of air can take away viruses and bacteria and reduce the infection rate. In the cold weather like heavy snow, it is necessary to keep indoor air circulation, which can effectively prevent the high incidence of colds.

4. Soak your feet in hot water

Soaking feet with hot water is an essential thing this winter. If you ride a bike to work every day, your feet will definitely feel cold and even freeze. So soaking your feet every night can not only warm your feet after a cold day, but also promote blood circulation of your feet and help the recovery of frozen parts of your feet. Besides, soaking feet every night can also relieve the fatigue of a day's work and make the night's sleep more practical.
