Sneezing is a common reflex in humans when the nose is overly stimulated to get rid of harmful germs and substances that want to invade the body. However, there is an undeniable fact, instead of sneezing once and then stopping, most of us when 'sneezing' are repeated two or three times in a row.

Recently, scientists at Cleveland Medical Center pointed out the cause behind the phenomenon. Accordingly, when external stimuli enter the nasal mucosa, the brain will allow release of histamine, stimulating the neurons in the nose to cause sneezing.

However, stimulating components are often difficult to completely disappear if you sneeze only once. The first sneeze will actually only remove harmful germs and dust into the outer parts of the nostril. Therefore, nerve cells in the nose are often triggered "harshly" several times in a row to achieve the highest efficiency in removing contaminants completely.

Dr. Dawn Zacharias also said that this intercourse sneezing reaction actually depends on the sensitivity of the nerve cells in the nose of each person . Specifically, there are those who just rub, lightly rub their nose and can sneeze, even from 10-15 times in a row but on the contrary, there are very few people who experience that feeling.

In particular, statistics show that 18 - 20% of the world population will sneeze continuously if looking at the light too bright. This is a sneeze reflex that is genetic. However, until now, scientists have not found the true mechanism behind this phenomenon.
