My friend told me that helmets don't prevent concussions. If that's true, what's
the point of wearing one when I ride my bike? – Eddie
Here's why people wear helmets when biking,
skiing, or doing other activities
that can lead to head injuries: Helmets are a way to help protect your head
from injuries like cuts and skull fractures. Always wear a helmet when doing
any sport or activity where there's a chance you might hit your head against
something like a tree, the ground, or another person.
Your friend is right: No helmet can prevent concussions.
There's no way to keep the brain from moving inside the skull. If you hit your head
hard enough, your brain can bang into the hard bone and cause a concussion.
Some "special" sports helmets and other new products claim that they can protect
you from concussions. But studies don't back up these claims. As long as a helmet
is right for your sport, hasn't been damaged, and is approved by the sport's governing
body, it really doesn't matter how much it costs or how fancy it is.
Concussions aren't always preventable. But you can
avoid other serious problems by taking care of yourself if you get one. If you take
a hit to the head while playing sports, sit out the rest of the game
and get advice from your doctor.
