Parents constantly try to protect their children from bad habits. There is hardly a child who has not heard from a very young age how many microbes are under the nails and that is why they should not bite them. However, Canadian scientists claim that this habit is really good for health, reports the Med Heal portal.
Young children have often been intimidated by adults with sinister stories about germs lurking under their nails. For the most disobedient, even methods such as pepper or mustard are used to keep them away from the bad habit.
However, the authors of the present study debunk this myth.
Experts at McMaster University have conducted a study demonstrating the futility of parental bans. The researchers note that when biting your nails, dirt and bacteria enter the body, and this is the health benefit. Scientists compare the bad habit to a vaccine. They explain that the number of microbes in the body is so small that the body can easily deal with them and develop immunity.
