As a neuroscientist with a focus on cognitive functions and neural health, I can tell you that the idea of losing brain cells when you sneeze is a misconception. Sneezing is a reflex action that occurs when irritants enter the nose, and it's a way for the body to expel those irritants. While sneezing does cause a momentary increase in pressure within the body, it does not have a significant impact on the brain or its cells. When you sneeze, the pressure in your body does increase momentarily, which can lead to a temporary decrease in blood flow to the heart. However, the heart compensates for this by adjusting its rhythm. According to Dr. Richard Koller, a sneeze does not kill brain cells. The brain is well-protected within the skull, and the force generated by a sneeze is not sufficient to cause any damage to brain cells. So, to answer your question directly: No, you do not lose brain cells when you sneeze. read more >>

When sneezing, the pressure in you body increases momentarily. This causes the blood flow to the heart to decrease. The heart then adjusts, changing the regular heart beat to make up for the lack of blood flow. As reported by Dr. Richard Koller, a sneeze does not kill brain cells.read more >>
