Autumn and winter are epidemic seasons for respiratory diseases. When the climate is changeable, how should we prevent respiratory diseases? Respiratory infectious diseases are mainly transmitted through the air droplets of patients or recessive infected persons carrying viruses and bacteria, or through close contact or indirect contact. When respiratory infectious diseases are prevalent, people should not go to crowded places as much as possible, and masks should be worn in public places. The room should always be ventilated by opening windows to keep the indoor air fresh. Do not go outdoors in foggy weather. Pay attention to personal hygiene, do not spit anywhere, wash daily necessities in time, and disinfect when necessary. In terms of diet, you can eat more yin nourishing and lung nourishing foods, such as pears, lilies, lotus seeds, etc. You should eat more foods rich in high-quality protein, such as fish, eggs, milk, etc., to improve the disease resistance. Pay attention to avoid eating cold and spicy food in autumn and winter. Eat more vegetables and fruits to ensure adequate vitamin intake. In dry winter, drink more water to prevent water loss. In daily life, we should pay attention to the combination of work and rest, go to bed early and get up early, exercise regularly, and enhance the disease resistance. Avoid inhaling cold air and other irritating gases. The dry weather in autumn and winter can be alleviated by using humidifiers, mopping, etc. Patients with chronic respiratory diseases can perform breathing exercises to improve vital capacity and respiratory function. It is suggested that people who smoke for a long time should give up smoking. (Outlook New Times)
