Is it important to clean the skin in foggy days?

The persistence of smog weather will make many people feel uncomfortable outdoors, but generally speaking, we spend less time outdoors and spend most of our time indoors. But for workers who need to work outdoors for a long time, such as construction workers, sanitation workers, traffic police, etc. They are exposed to smog for a longer time and have a greater exposure. Therefore, it is necessary to emphasize and attach importance to the protection of outdoor workers against haze weather. Cleaning the skin can also avoid people with sensitive skin allergies, but don't over-clean the epidermis and lose your protective ability.

Haze's harm to human body;

(1) on the respiratory system.

The composition of smog is very complex, including hundreds of atmospheric chemical particles. Among them, aerosol particles smaller than 10 micron are harmful to health, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel, automobile exhaust, etc., which can directly enter and adhere to human respiratory tract and alveoli. In particular, submicron particles will be deposited in the upper and lower respiratory tract and alveoli respectively, causing acute rhinitis and acute bronchitis. For patients with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphysema, and chronic obstructive pulmonary disease, smog weather will make the condition acute or acute. Staying in this environment for a long time will also induce lung cancer. Therefore, wearing a mask when going out is effective in preventing smog.

(2) Effects on cardiovascular system.

Hazy days also have a serious impact on cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation, lead to cardiovascular diseases, hypertension, coronary heart disease, cerebral hemorrhage, and may also induce angina pectoris, myocardial infarction and heart failure. And cause pulmonary heart disease in chronic bronchitis.

In addition, when the air pressure is relatively low in foggy weather, people will feel irritable and their blood pressure will naturally rise. On the other hand, in foggy days, the temperature is often low. Some patients with hypertension and coronary heart disease suddenly go from warm indoor to cold outdoor, and blood vessels expand with heat and contract with cold, which will also increase blood pressure, leading to stroke and myocardial infarction. Therefore, patients with cardiovascular and cerebrovascular diseases must take medicine on time and handle it carefully.

(3) Hazy weather will also lead to the weakening of ultraviolet rays in the surface layer, which can enhance the activity of infectious bacteria in the air and increase infectious diseases.

(4) It is not conducive to children's growth. In foggy days, due to the decrease of sunshine, insufficient ultraviolet radiation for children, insufficient production of vitamin D in the body, and greatly reduced absorption of calcium, rickets in infants and young children will be seriously caused, which will slow down the growth and development of children.

(5) Affect mental health.

Experts point out that continuous foggy days have an impact on people's psychology and body. Psychologically speaking, foggy days will give people a feeling of depression, which will stimulate or aggravate the state of psychological depression. In addition, due to the weak light and low air pressure in foggy days, some people will feel lazy and depressed in foggy days.

(6) affecting reproductive capacity.

Studies have shown that the success rate of sperm in vitro fertilization may be reduced in people who have been exposed to high concentrations of polluted air for a long time. The researchers also found a link between toxic air and the decline of male fertility.
