Sports Safety

Playing sports can be fun, but it can also be dangerous if you are not careful. You can help prevent injuries by:

  • Getting a physical to make sure you are healthy before you start playing your sport
  • Wearing the right shoes, gear, and equipment
  • Drinking lots of water
  • Warming up and stretching

If you have already hurt yourself playing a sport, make sure you recover completely before you start up again. If possible, protect the injured part of your body with padding, a brace, or special equipment. When you do start playing again, start slowly.
