SNEEZES -- NOTHING TO SNEEZE AT
Sneezing is serious business according to
these myths:
· In ancient times, many
people believed that a person's soul was made of air and was located inside the
head. Therefore, sneezing seemed like an activity that would dislodge the soul
and allow it to escape.
· In the Middle Ages,
minor illness could lead to death, so the sound of someone sneezing was
frightening. People would say "God bless you" in an attempt to
protect the sneezer from sickness or death.
· Today, many people
believe that the heart stops during a sneeze. This is also a myth, but you can see why people believe it:
During a sneeze, when the chest expands and contracts, pressure builds up and
is then released in the chest. This change in pressure can lead to a change in
blood flow, which can cause a change in the heart's rhythm.
Why Do Your Eyes Shut When You Sneeze?
Some people's eyes don't shut when they
sneeze, but most people's do. So if there's no concern that our eyes will pop
out of our heads, then why do they close automatically?
You might think the eyes close as a defensive
mechanism -- to keep all those projectile germs and bacteria out of the eye.
But that's unlikely to be the case since the force of a sneeze sends the
particulates away from the face, not toward it.
The more likely reason that eyes close during
a sneeze is for no reason. It's just an involuntary reaction with no real
purpose. The eyes may close during a sneeze for the same reason your leg kicks
out when your knee is tapped. It's not just the muscles in your eyelids that
react during a sneeze. Many muscles all over your body react. For example, many
people with stress incontinence experience urine leakages when they sneeze --
the result of those muscles tensing and releasing involuntarily.
So it's a pretty disappointing conclusion: The
body forces your eyes to shut during a sneeze, but there's no real purpose for
this action. Instead, it's a reflex that may have had a purpose at one time,
but serves no function now.
