No, heart and other body parts continue working when you sneeze

“Did you know when you sneeze, all body parts stop functioning even your heart?” This is according to a recent post shared in a public Facebook group in Kenya.

Sneezing is a sudden involuntary response to irritation of the mucous membranes of the throat or nose by foreign particles.

According to the Library of Congress, the pervasive myth about the heart not beating as you sneeze might be that, since the blood flow changes during sneezing, your heart skips some beats. 

But is this true? We checked.

Dr David Rutlen, a cardiologist at the University of Arkansas for Medical Sciences in the US, says in this Youtube video that the heart does slow down.

“This is something comparable to a valsalva manoeuvre,” Rutlen says. “Built up pressure in the chest can cause a vagal reaction pertaining to the vagus nerve, which is part of the nervous system that controls the heart, that slows down the heart. The heart could hold in place for several seconds.”

“Even if it’s possible for the heart to stop, this is nothing to be concerned about,” says Rutlen.

According to Winchester Hospital in Massachusetts, US: “When you first inhale before sneezing, the pressure in your chest increases. Then, as you exhale forcefully during the sneeze the pressure drops. 

“Alterations in blood flow to your heart produced by these pressure changes can affect the heart rate. However, the electrical activity in the heart marches on unimpeded – you remain very much alive throughout your sneeze!” – Grace Gichuhi 


Africa Check teams up with Facebook

Africa Check has partnered with Facebook to combat fake news and false information on the social platform. This fact-check is part of the initiative.

As part of its third-party fact-checking programme, Facebook allows its partners to see public articles, pictures or videos that have been flagged as potentially inaccurate.

Content rated as “false” by fact-checkers will be downgraded in news feeds. This means fewer people will see it.

You can help us identify fake news and false information on Facebook. This guide explains how.
