The large temperature difference between morning and evening in autumn and the dry weather will increase the risk of catching a cold. So when you go out, you should pay attention to the weather forecast, take a coat with you, and increase or decrease clothes according to the weather changes. The time to go out in the sun is controlled within 20 minutes. Don't keep pets, spread carpets, put flowers that spread pollen at home, and don't go to places in bloom to avoid allergic reactions caused by pollen entering the respiratory tract.

2. Don't wash your face with cold water.

The nasal cavity is directly connected with the outside world, which is the first line of defense for the lungs, but it cannot withstand the stimulation of cold water. Wash your face directly with cold water, which will make the blood vessels of nasal mucosa contract and damage the respiratory function, thus prolonging the healing time of the wound. Wash your face with warm water at 50~60℃ every morning and evening. At the same time, you can't wash your face with hot water above 60℃, otherwise it will relax the capillaries and stimulate the respiratory tract.

3. Keep moderate exercise.

There are many sandstorms in autumn, so patients with lung cancer can't do any headwind exercise after operation, so as not to make the respiratory tract stimulated by strong winds. Usually, you can do more qigong exercises, especially qigong to enhance respiratory function, which can effectively improve cardiopulmonary function. Analgesics should be used reasonably before each exercise, and nursing staff should help them to expectorate specially. Exercise should be based on not feeling chest pain and fatigue.
