Recently, respiratory diseases have been "stable" in the first place among the patients treated. Professor Tong Zhaohui, deputy director of the Institute of respiratory diseases, Beijing Chaoyang Hospital, said that winter and spring were the high incidence seasons of respiratory diseases such as acute upper respiratory tract infection, influenza and acute pneumonia. The high temperature provided many favorable conditions for many pathogens, and the breathing system was most susceptible to pathogens, so in warm winter, Respiratory infections will increase. In addition, the dry weather brought by warm winter also contributed to the fire.
"It's bad for human health if it doesn't snow." Mei Xue, deputy chief physician of the emergency department of Beijing Chaoyang Hospital, said that the air is dry, and people are prone to dry lips, bleeding nostrils and itchy throat.
Research shows that when the air humidity reaches 45% - 65%, it is conducive to the treatment and rehabilitation of lower respiratory tract diseases. When the air humidity is lower than 40%, the respiratory mucosa of nose and lung will be dehydrated and the elasticity will be reduced, making dust and bacteria easy to adhere to the mucosa, stimulating the throat, causing cough, pneumonia and asthma. Snow can purify the air and eliminate pollution. If it doesn't snow, it is easy to have multiple respiratory diseases such as asthma and pneumonia.
Experts suggest that when you go out in dry days, you must keep warm and pay attention to the temperature difference between indoor and outdoor. The indoor temperature should not be too high. The room temperature should be about 18 ℃ and the relative humidity should be controlled at 30% to 40%. For the elderly with respiratory diseases, it is best to wear masks when going out. In the weather with high air pollution index, outdoor activities should be reduced. It is recommended to breathe with your nose. Your nose can "humidify" the air, so as to purify the air and reduce the invasion of bacteria. Wash your hands more. When you go home from outside, you must wash your hands well with soap. In addition, we should also pay attention to drink more water, strengthen exercise, and ensure adequate sleep and nutrition
Experts suggest that in a dry environment, Aroma Diffuser can be used to alleviate air drying, moisturize the skin and solve the problem of drying
