Resist air pollution and lung disease in the summer. Don’t be afraid! Air purifier
At the end of 2018, the World Health Organization (WHO) organized the first global conference on air pollution and health specifically for the growing problem of air pollution. Under the dome, air pollution has become one of the major causes of death in the world. It is estimated that 29% of global lung cancer, 24% stroke, 25% of heart disease and 43% of chronic obstructive pulmonary disease patients are caused by air pollution. Due to air pollution, health may be compromised even if you do not smoke.
Air pollution should be seriously faced
In recent years, as the number of smokers has decreased, the lung diseases caused by cigarettes have gradually declined, but they have continued to rise due to the deterioration of air pollution. In particular, some malignant lung diseases are difficult to detect, and most of them are late.
The PM2.5 in air pollution is small in size and can penetrate the alveoli into the blood circulation, which may cause harm to the whole body’s health. When it enters the lungs, it may cause inflammation and obstruction of the respiratory tract. After entering the blood circulation, it will cause inflammation and hardening of the blood vessels. In addition, many toxic substances may inhale with PM2.5, such as heavy metals or polycyclic aromatic hydrocarbons. In addition to guarding against outdoor pollution, indoor air pollution should not be neglected, especially polycyclic aromatic hydrocarbons produced by frying and frying, which are often a source of indoor air pollution. Long-term exposure is more likely than outdoor air pollution. Induced disease.
Under the environment of poor air quality, how should we resist air pollution and prevent lung diseases?
Does the portable air purifier work?
Portable air purifiers have been popular in recent years, but many experts believe that portable air purifiers have limited effectiveness. In fact, it is useful to use the air purifier in a confined space. First, the external pollutants are blocked, and then the indoor air is filtered to achieve the purification effect.
If the portable air purifier is used outdoors, once the filter is too small, it will not be able to clean up in the face of continuous oncoming pollution. Secondly, it will be easily disturbed by airflow, and the purified air will be blown away and worn. The position is mostly at the neck and there is a distance from the nose and mouth, so the inhaled air is not necessarily clean air.
Many doctors also have reservations about portable air purifiers. He pointed out that portable air purifiers have too little ventilation and too low filtration capacity. Unless they are worn in front of the nose, they may be a little help. The mask comes practical.
How to prevent the confined space inside the car?
Driving for a long time or traffic jams often makes people feel drowsy, and even feel chest tightness, headache, and uncomfortable breathing. It may be caused by air pollution inside the car. The leather dyes, plastic adhesives, or chemicals used for cleaning in the vehicle will continue to volatilize in the air. Some people like to put blankets and fluffy dolls in the car, which are easy to adhere to dust mites and dust, while the fragrance is It may release toxic substances such as formaldehyde. Many people think that the inside of the car is a confined space, which will block the air pollution inside the car. The air inside the car should be better than the car. In fact, it depends on the situation. Sometimes car air conditioners introduce air outside the car and circulate inside the car. If the air outside the car is poor, the car is clogged, or the car is in the tunnel, or the front car is a diesel truck with a large exhaust volume, it may cause air pollution inside the car. more serious.
Under normal circumstances, it is recommended to close the window when driving, and you can add a car air purifier, which is somewhat helpful. If you need to drive for a long time, when the air quality outside the car is good, you can open the window to help the air circulation. In addition, not smoking in the car (even if the window is opened), avoiding the use of chemical lotion, reducing the decoration, keeping it clean, and opening the window to open the air before getting on the car, will help improve the air quality inside the car. In addition, he also shared that he actually wears a mask when driving, which is the most cost-effective way to prevent air pollution.
Any filter air purification device should always change the filter. Instead of spending extra money on the purchase of air purifiers for vehicles, it is also necessary to change the filter screen regularly to drive the air conditioning filter for six months to one year or 5000-10000 km. In addition, before the flameout, the air is blown for 5-10 minutes and then turned off, which can help the evaporator of the air conditioner to dry, avoid the mildew of the evaporator and reduce the pollution of mold spores in the car.
