Consider it a reset if a person is in the middle of a heart attack a sneeze would be great however coughing repeatedly (@short intervals) will also soften or "tone down" a heart attack, so IT DOES HAVE AN EFFECT
yes, professionals say so. that's why we say bless you. if our heart didnt stop when we sneeze, whats the point of saying bless you?, so why can't we say that if we cough or choke, or laugh? so yes, our heart stops for about 2 to 3 seconds, when we sneeze. but think of what i said. thumbs up!
Yes it does. When you sneeze, all bodily functions stop, briefly though. So technically, yes your heart does stop beating because your heart pumping blood does count as a bodily function. Without this you would die but we all know that right? Some would be quick to say that it doesn't because you are still alive but really, it does stop for a millisecond. If you were to look it up, you would find lots of people say no it's a myth but it's not.When you sneeze your Eyes close, your chest contracts and your lungs expel air, and your heart stops for a second, but not long enough to really say you died or to make it a proven fact. If you wanna get really technical, then technically your heart "stops" between every beat.
No. The heart does not stop when you sneeze. "Bless you" has been around for thousands of years. Ancient people did not have the technology to have known if the heart stopped or not. They believed that when you sneezed that it was a way for evil spirits to enter your body so they quickly "blessed" you in order to "save" you.
