How to protect yourself from polluted weather

In haze weather, you should have a light diet, drink water frequently, eat less irritating food, and eat more fresh fruits and vegetables. This can not only supplement various vitamins, but also moisten the lungs, remove dryness, and eliminate phlegm. It has the functions of relieving cough, strengthening the spleen and nourishing the kidneys. Eat less irritating food, eat more pears, oranges, lilies, black fungus and other foods that can nourish yin and moisturize the lungs, eat more tofu, milk and other foods, and supplement vitamin D if necessary. In terms of daily life, wash hands frequently, avoid overexertion, avoid staying up late, pay attention to rest, and maintain adequate sleep, which is of great help in improving the body's immunity. It is not advisable to exercise in hazy weather. Those who have exercise habits should stop outdoor running and walking. It is best not to perform cardiopulmonary exercise, such as high-intensity running. Because during strenuous exercise, the body will inhale more harmful gases than usual. At the same time, the air pressure is low in haze weather, and strenuous exercise in patients with high blood pressure and coronary heart disease can easily induce angina pectoris and heart failure. It is recommended to choose relatively modest indoor projects. Schools should also try to reduce students' outdoor activity time as much as possible and move physical education classes indoors, where they can do indoor skipping, sit-ups or exercises.
