What diseases can children have in foggy days?

Physiologically, children's respiratory tract is very fragile, and infants have no nasal hair barrier. The nasal cavity is shorter than that of adults, and its curvature is not as large as that of adults, so harmful substances can directly reach bronchioles and alveoli with the airflow. Therefore, children are more sensitive to bad weather. Harmful particles in smog can directly enter and attach to children's respiratory tract and alveoli, causing acute rhinitis and acute bronchitis. If not treated in time, it is easy to turn into pneumonia in children. If it coincides with the epidemic period of respiratory diseases such as influenza, smog weather will further promote the occurrence and spread of such diseases.

2, aggravate chronic respiratory diseases

For children with bronchial asthma, chronic bronchitis and other diseases, smog weather will make the disease acute or acute. Studies have shown that the increase of PM2.5 concentration is significantly related to the increase of the number of respiratory diseases in children, and the increase of PM2.5 can increase the emergency treatment rate of asthmatic children.

3, cause conjunctivitis

In foggy weather, suspended particles in the air attach to the cornea, which can cause conjunctivitis. Conjunctivitis usually does not affect vision, but it is also difficult to relieve itself. Therefore, once the child blinks frequently, rub his eyes. When you roll your eyes and have symptoms and signs such as red blood, you should see a doctor in time. For general eye discomfort, parents can use cold compress to help their children relieve discomfort symptoms.

4. Emotional instability

Hazy days can also affect children's emotions. Because the weather is cloudy all day and there is no sunshine, the pineal gland of the child will secrete more testosterone, which will reduce the concentration of thyroxine and adrenaline, leading to emotional instability.

5, damage the health and development of children.

Heavy metals in suspended particles are also very toxic to children. Heavy metals can combine with hematoporphyrin in blood and damage the liver. After inhaling too much heavy metals, children's blood viscosity increases and oxygen content decreases, which will lead to chest tightness, dizziness and other symptoms. Lead in heavy metals has obvious damage to the nervous system and affects children's nervous system and intellectual development. Iron attached to particles will produce hydroxyl radicals, which will cause oxidative damage to the lungs.
