Whilst we sneeze, the air through our nostrils flies at a speed of 160 kilometers per hour. If you deliberately stop the sneezing, the whole pressure will carry to another part of the body, which can suffer.
The way of sneezing differs at home or at a meeting, i.e. it can be relaxed or restrained. It may seem more decent to stop the sneezing in public, but it is certainly not good for the health. While we sneeze, the air through our nostrils flies at a speed of 160 kilometers per hour.
If you do not sneeze, all the pressure moves into the ear, which can lead to cracking of the ear drums. It can cause dizziness that will not stop quickly and hearing loss.
Also, another thing that will suffer is the blood capillaries in the eyes, which will crack due to pressure, and it can as well damage the diaphragm. The stronger gust and then stopping the sneezing, is a potential risk for fresh wounds in people who recently have operated their sinuses, as well as neck injuries. And the worst thing that could happen is popping the veins in the brain and stroke, which can be deadly.
So, if you feel like sneezing in public, do not be shy, since the price you can pay is huge.
