Detailed explanation-1: -When you sneeze, the intrathoracic pressure in your body momentarily increases. This will decrease the blood flow back to the heart. The heart compensates for this by changing its regular heart beat momentarily to adjust. However, the electrical activity of the heart does not stop during the sneeze.

Detailed explanation-2: -A person may wake up and sneeze at night, but it is not possible to sneeze during sleep. Sleep causes paralysis of the reflex muscle contraction, meaning the relevant muscles become inactive. This article explores the different stages of sleep and how they affect the involuntary body function of sneezing.

Detailed explanation-3: -If you do notice you sneeze more frequently, you may have an allergy that you are unaware of or inflammation of the nasal cavity called chronic rhinitis. It doesn’t hurt to talk to your doctor about your sneezing habits if you think they are abnormal.
