It’s the season of “gathering around the fire” again, and the Centers for Disease Control and Prevention has issued the latest reminder

After entering the heating season, many environmental health problems arise. Recently, the Qingdao Center for Disease Control and Prevention issued a health reminder, asking citizens to pay attention to the health risks caused by carbon monoxide accumulation, dry indoor air, and reduced window ventilation.

Carbon monoxide poisoning is a rare fatal poisoning incident among environmental health problems. Carbon monoxide poisoning incidents in Qingdao during the heating season are mainly caused by improper use of coal or firewood for heating. Wang Yin, an expert from the Municipal Center for Disease Control and Prevention, reminded that the behaviors of "making tea around the stove" and "roasting oranges around the stove" that have become popular in recent years may also lead to carbon monoxide accumulation and even poisoning due to improper handling of charcoal fire.

There will be more haze days in winter. Patients with cardiovascular and lung diseases, as well as sensitive groups such as the elderly, children and pregnant women should pay special attention. Citizens can pay attention to the Air Quality Health Index (AQHI) before traveling and choose their own health protection measures according to the index level.

While enjoying the warmth of the heating season, citizens generally face health problems caused by dry indoor air (relative humidity is too low). Some citizens may experience dry lips, dry nose, dry throat, dry skin, and even symptoms such as peeling and itching of the skin, nosebleeds, and irritability. Research results show that low relative humidity may make people more susceptible to airborne viruses and bacteria.

Wang Yin suggested that citizens can place green plants indoors. Daily watering is conducive to increasing air humidity, and the plants themselves can also purify the air. Citizens can also use a damp mop to wipe the floor, or use a humidifier to increase indoor humidity. However, humidifiers must be cleaned regularly to avoid bacterial growth in the humidifier. "Citizens can also place a basin of water at the bottom of the radiator or put a wet towel on the radiator, or raise fish indoors to increase indoor air humidity." Wang Yin said that in daily life, citizens should drink more water and use some moisturizing skin care products.

During the heating season, due to the cold weather, citizens open windows for ventilation less frequently and for less duration, which may lead to the accumulation of toxic and harmful pollutants indoors and the decline of air quality. At the same time, people spend more time indoors than in other seasons, which is more likely to cause harm to their health. Wang Yin suggested that citizens should open windows for ventilation at least three times a day, for 15 to 20 minutes each time, and open windows for ventilation at any time according to their own sensory perception and outdoor air conditions.
