Dear MEL Topic Readers,
Why it’s so good to scratch an itch?
What’s the difference between an itch and a pain? They both are stimuli
to the spinal cord and brain, one is caused by a weak stimuli and the other is by
a strong one. Also, while one can be healed or eased by scratching, the other
is certainly not.
Itches can be caused by an insect bite, dry air, skin disease, or other
mental or physical disorders. And no matter what the cause is, scratching an
itch always brings one immediate pleasurable sensation or relief.
Are you getting itchy or do you feel like scratching some part of your
body? That may be because itches are often contagious, like yawning.
Enjoy reading and learning what an itch is about and why people scratch
it.
