The air quality in Annan District, Tainan City is poor; at 8 a.m. today (21st), the Ministry of Environment monitoring showed that the air quality at Annan Station reached "unhealthy for sensitive groups" and the main pollutant was PM2.5.
He Jianhui, a thoracic physician at Annan Hospital, reminded on the Facebook fan page "Pulmonary Medicine-Dr. He Jianhui" that friends with sensitive respiratory tracts should pay attention. Why is this happening? He Jianhui explained that this is because the cool air from the front edge of the northeast monsoon arrives, and there is an obvious temperature inversion in the central part. PM2.5 is like being covered with a lid and quickly accumulates. Coupled with the weak north wind blowing in the western half, pollutants move all the way south.
He Jianhui reminded: Don’t worry, the sea breeze will strengthen in the afternoon and the diffusion conditions will improve, so the concentration is expected to gradually decrease. However, special attention should be paid to these types of friends: patients with asthma, COPD (pulmonary obstruction), cardiopulmonary diseases, elders, children and pregnant women.
●Reduce strenuous outdoor exercise. Morning jogging and cycling can be moved indoors, or you can wait until your symptoms improve in the evening before going out.
●Wear a mask when going out, and wash your hands and face when you return home.
●People with asthma or COPD should carry first-aid inhalants with them, use maintenance medicine as usual, and do not stop taking medicine by themselves.
●If you experience chest tightness, wheezing, or coughing more frequently, or if the dosage of emergency inhalants increases significantly, please seek medical attention as soon as possible.
