Haze hazards and preventive measures.

Smog is no stranger to many people. We know that smog not only brings inconvenience to people going out, but also harms people's health. So what are the hazards of smog? How can we prevent the harm caused by smog to human body?

Hazards of smog

There are nearly 20 kinds of fine particles and toxic substances harmful to human body in smog. It will bring health hazards to the human respiratory tract, cardiovascular and cerebrovascular systems. For young children, smog will affect their normal physical development.

Affect respiratory tract

Harmful fine particles and toxic substances contained in smog are easily inhaled into the human body, and directly enter the throat and bronchus from the nostrils, which interferes with the gas exchange in the human lungs. When it enters the throat, it is easy to cause inflammation. When it affects the bronchi, it will affect the normal gas exchange in the lungs and easily lead to respiratory diseases such as acute rhinitis, bronchitis and bronchial asthma. Patients with respiratory diseases themselves are easy to relapse and aggravate their illness in foggy days.

Affect the cardiovascular and cerebrovascular systems.

There are many pollutants in the air in haze weather, especially in low-pressure weather, which easily affects the normal blood circulation of human body and easily induces diseases such as heart disease, hypertension and coronary heart disease. Especially when going out, outdoor cold is easy to cause blood vessels to expand with heat and contract with cold, leading to an increase in blood pressure.

be carcinogenic

There are as many as 20 kinds of harmful fine particles and toxic substances in haze weather. Among them, many carcinogenic substances, such as aromatic hydrocarbons, may lead to cancers such as lung cancer, especially in places with serious industrial pollution, and people are at higher risk of cancer.

Hazy weather with poor light and low air pressure on people's heads can easily lead to mental fatigue, depression and pessimism, and easily lead to mild depression.

Impact on children

In smoggy weather, children can't receive sunlight, which will affect the body's acquisition of vitamin D. Insufficient vitamin D content in children will seriously affect the body's absorption of calcium, easily affect the normal bone development of children, and easily suffer from rickets; In addition, the smog weather can easily affect the hormone level in children, leaving children in a state of burnout and loss of appetite for a long time.
