First of all, make a good habit of checking the air quality, pay attention to the air quality and pollution index daily, watch the weather forecast, pay attention to some emergencies, have a general idea of the possible pollutants in the surrounding environment, especially in geographical areas such as factories and businesses, and adjust the place of outdoor exercise or the timing of walks according to the quality report. Stay away from heavily polluted areas or stay for as short a time as possible. When walking, try to avoid busy streets with lots of cars; go to less “foggy” places; and the warmer the day, the worse the air quality. So try to schedule outdoor activities in the morning and evening to avoid the damage of UV rays and pollutants during the midday hours. Since air pollution cannot be avoided, it is important to filter and freshen the air as much as possible, and to turn on the air filter when driving. (If possible, use a high-efficiency air filter), which helps filter out very fine suspended particles; change the air conditioning filter regularly at home or in the car. Keep the room dry to avoid moldy substances such as fungal spores floating in the air, which can be inhaled by you and cause allergies. If the air is really bad, especially on hazy days, it is best to wear a mask, an umbrella and a hat when you go out, or even wear sunglasses and long sleeves and long pants to reduce the exposure of air pollutants to skin and hair and UV damage to the skin, and also to avoid eye irritation. When you encounter hazy days, rinse your hair and face in time after you get home, but do not over wash and apply washing chemicals to avoid secondary damage to the skin, rinse off the pollutants floating on your body and use some skin care moisturizer appropriately to strengthen the moisturizing of the skin. Wash the clothes and other items under the change in time to avoid secondary pollution of the room, etc. For allergies and other diseases that have triggered the skin, go to the hospital in a timely manner, take some oral anti-allergy drugs, and under the guidance of the doctor, use hormonal ointments and emollients as appropriate according to the local skin lesions. For possible free radical damage, some vitamins such as B and E can be taken appropriately, including some antioxidants, etc., such as the consumption of fruit olives, cherries, red pomegranates, grapefruit, grapes, carrots, lemons, etc., supplementation of trace elements such as selenium, magnesium, etc., to reduce the occurrence of aging, some can be treated with the help of topical drugs or laser. For possible heavy metal poisoning can be treated by drinking more water or biophysical treatment with some drugs to accelerate excretion and reduce further metal pollutants into the body.
