Previously, speaking with Tuoi Tre Online , Dr. Hoang Duong Tung - an environmental expert said that according to monitoring information released by authorities, Hanoi and many northern provinces have entered the "season" of air pollution.
Air pollution “recurs as scheduled” despite many localities taking steps to find and prevent sources of pollution and PM2.5 dust. According to Mr. Tung, the “season” of air pollution usually lasts from October to the end of March of the following year.
How does poor air quality affect health?
Talking to Tuoi Tre Online , many medical experts said that when air quality is bad and there is a lot of dust in the environment, the first and most obvious people affected are patients with existing respiratory diseases.
Poor air quality makes people feel short of breath, cough a lot, accompanied by chest tightness and signs of an acute attack will appear. Therefore, people with respiratory diseases should not go out unless absolutely necessary during times when the air is polluted.
For patients with asthma and chronic obstructive pulmonary disease, it is necessary to comply with and maintain daily medication as prescribed by the doctor. When there are signs or symptoms of discomfort or difficulty breathing, it is necessary to increase the dose of bronchodilator according to the doctor's instructions.
