The popular belief that your heart stops when
you sneeze is actually just a myth. When you
sneeze, a lot of pressure builds up in your chest
for a brief moment and it is plausible that the
pressure could temporarily affect your blood
pressure and heart rate. However, that pressure
does not cause a heart to stop beating. Rather,
your heart beat is kept steady by a continuous
cycle of electrical signals automatically
generated by your body. Essentially, your heart
has a built-in pace maker that makes sure your
heart maintains a regular beat at all times. If
you are wondering why people say "bless you" after
someone sneezes, I believe it stems from an old
belief that bad spirits can enter into your body
and soul when you sneeze. I think there are
several versions of this, but that's the gist of
Actually that seems to be a myth!! According to
an MD/PhD at Washington University, a sneeze does
not stop the heart. The heart is on automatic
control by your body and something like a sneeze
would not stop the heart from
contracting/relaxing. However, it is possible that
occasionally your heart may "skip a beat" due to a
change in pressure in your chest as you sneeze.
This change in pressure could affect blood flow.
However, it does not stop the heart from beating.
Think of it more like a slight disruption in
traffic flow through your heart. Hope that helps!!
