Children's immune system is relatively fragile, studies have shown that infants and children's respiratory rate is two times that of adults. Indoor air pollutants are concentrated in the lower levels of the air, which makes children more vulnerable. It affects children's physical and mental development, and in severe cases can cause asthma and even leukemia.
Studies have shown that when the indoor formaldehyde formaldehyde concentration of 0.24-0.55 milligrams per cubic meter, 40% of women of the right age will experience menstrual disorders, long-term exposure to low concentrations of formaldehyde can cause pregnancy syndrome in pregnant women, caused by the newborn baby's physical fitness is lowered, and the high concentration of formaldehyde can also induce fetal deformities, infantile leukemia and so on. Another study proved that benzene also has adverse effects on embryonic and fetal development, and in severe cases can cause fetal malformation or even death.
Elderly people's body functions are gradually declining, the immune system deteriorates, indoor harmful substances are most likely to vulnerable groups. The elderly long-term in the "gas chamber", the light triggered respiratory inflammation, hypertension, cardiovascular disease, the serious will be life-threatening.
Children's immune system is relatively fragile, studies have shown that infants and children's respiratory rate is twice as fast as that of adults. And indoor air pollutants are mainly concentrated in the lower air levels, which makes children more vulnerable to hazards. It affects children's physical and intellectual development, and in severe cases, can trigger asthma and even leukemia.
It is said that 80% of a person's life is spent indoors, and this is especially true for white-collar workers. Sitting indoors for a long time, the air does not circulate will lead to insufficient oxygen and air pollution, dizziness, headache, chest tightness, shortness of breath, emotional ups and downs of the many white-collar workers of the true picture.
