What is the difference between child smog prevention and adult use?
First of all, compared with adults, children are at a disadvantage in their physiological structure in the fight against smog:
Children's nose hair is not thick enough. Nose hair is the first line of defense to prevent particulate matter from entering the respiratory tract. Humans will come with nose hair when they are born, but they are very small, and they usually grow longer when they are 6-7 years old, but they are denser than adults. The ratio is still very different. Therefore, children first have one less line of defense than adults. Children breathe faster. Children's breathing rate is faster than that of adults, and more pollutant particles are ingested in the same time, and the greater the damage to the body. Children's lungs are immature. If too much pollutants are ingested, children are more likely to breed bacteria and viruses than adults. Therefore, in the smog environment, children also need to be protected more than adults.
