Nose-picking is considered to be bad for various reasons. It is unhygienic and can destroy the fragile skin in your nostrils. You might also develop synusitis.
Doctors have however, said that the habit has a few advantages, especially for growing children.
Boogies and snorts are said to have salivary mucins which protect the teeth from bacteria that would cause cavities.
Australian lung specialist, Prof Friedrich Bischinger, says that eating the dry remains of your nose strengthens your immune system. He added that medically, it makes great sense and is perfectly normal, as reported by the Standard.
"In terms of the immune system, the nose is a filter in which a great deal of bacteria are collected, and when this mixture arrives in the intestines, it works just like medicine," he says.
