How much harm does smog do to people?

For the harm of smog, most people stay in the cognition of lung injury, but the harm of smog is far more than that.

Let's first analyze why it hurts the lungs. I first heard the concept of PM2.5 because of smog. Hundreds of kinds of atmospheric particles produced by smog weather can't be kept out by our respiratory system and nasal mucosa. He can directly enter our body and harm the respiratory tract and lungs. It is reported that a young man had the habit of running and exercising outdoors and died of lung cancer. He had no hobby of smoking. This shows how harmful smog is to the human body. The most terrible thing is that human lungs have no self-purification function. At present, the most advanced medical experts say that once smog pollutants enter the lungs, they will quickly and permanently precipitate and directly dissolve in the cells of your lungs. You can't even leave the hospital for surgery.

Second, smog hurts the heart and cardiovascular and cerebrovascular diseases. Haze particles are easy to induce myocardial infarction and cardiovascular diseases. There are many pollutants and high water vapor content in smog. If people don't exercise outdoors, their blood pressure will rise, not to mention going out for a run in foggy days. Under the influence of haze, abnormal coagulation occurs frequently, and it will increase the viscosity of blood. Therefore, in the smog environment, the number of people who die from cardiovascular diseases will be more than that in normal weather 10%- 15%, and if the smog days are not treated continuously, the aging speed of people will also be accelerated.

Third, smog hurts the skin, because the environment when smog occurs is very poor, and all kinds of bacteria are easy to breed in this environment. The skin itself has a respiratory function, and the invasion of bacteria not only erodes the body, but also makes the skin very uncomfortable.

Fourth, pregnant women must pay attention to going out as much as possible in foggy days, because it has a great impact on the development of the fetus. The existence of harmful substances such as metals in smog atmospheric particles will reduce the immunity of pregnant women and directly poison babies through the placenta. Especially in the early pregnancy, many fetuses become "stillbirths", and their development is delayed until they no longer develop, or children with cancer or deformity at birth are inseparable from the harm of smog.

Fifth, it affects people's access to vitamin D in the sun, and it is definitely not possible to bask in the sun in foggy days. This will not promote the absorption of active vitamin D, especially harm children, which will make children grow slowly, lose appetite and have weak limbs. The end result is rickets.

For the health of yourself and your family, try to avoid foggy days and go outdoors more. Wear a mask and choose a certified anti-fog mask. If possible, it is best to install an air purifier at home.
