Some men think that wearing a big beard can highlight masculinity, appear dignified, solemn and artistic. There is nothing wrong with growing a beard, but from a health point of view, it is harmful and useless to grow a beard too long.
This is because the beard itself has the characteristics of absorbing harmful substances. When people breathe, they can emit a variety of harmful chemical gases, and they can stay on the beard; the atmosphere contains a variety of heavy metal particles, especially in busy streets, the polycyclic aromatic hydrocarbons and lead emitted by automobile exhaust will also be absorbed by the beard; smokers, carcinogens such as benzopyrene in the smoke, will also stay on the beard. These harmful substances are adsorbed on the beard. As people breathe, they will be inhaled into the mouth and nose, which will cause circulatory harm to health. It is like placing a “pollution source” on the mouth and nose;.
In addition, if the beard is too thick and dense, it will absorb a lot of bacteria, dust, food residue and other dirty things, which will also have adverse effects on people’s health.
