Seven-year-olds always like to pick their noses with their thumbs. Is this bad for their noses?

First of all, most of us know that booger digging is harmful to the nose, but many people think that booger digging can be ignored as long as it is light or has little harm. In fact, this idea is wrong. The hazards of picking your nose mainly include the following:

1, bacterial invasion

When picking your nose, even if it is light, it will hurt your nose, because there are many bacteria on our hands. At this time, if you touch the inside of the nostril, it is very likely that most bacteria will invade your nose, and some bacteria will flow into our respiratory tract, causing our nasal cavity or respiratory tract infection, which may even lead to sinusitis in severe cases.

2, nosebleeds

There are many capillaries in the nasal cavity. Picking the nostrils often hurts the capillaries in the nasal cavity, which makes us particularly prone to nosebleeds. The capillaries in the nasal cavity are closest to the brain. Therefore, nasal capillary bleeding may lead to bacteria flowing into capillaries, leading to bacteria invading the brain, which will seriously lead to intracranial bleeding, which has great hidden dangers to health. Therefore, friends who often like to pick their nostrils must pay attention and try to quit this bad habit.

Finally, I personally think that picking your nose is a very uncivilized and unhealthy behavior. Friends who study etiquette know that picking your nose is forbidden, and picking your nose in front of others is also considered to be particularly impolite. But picking your nose will leave a hidden danger to our health. It can be said that picking your nose is harmful and useless. Therefore, no matter from which angle, we should get rid of this bad habit and be a civilized and healthy good citizen.
