Summer is the perfect time to head out to the pool. Swimming is a great way to cool off from the hot sunshine and the sun-warmed water is never too cold to dive right in. Of course, not everyone at the pool is splashing around in the water. Lifeguards, often teenagers and young college students out of school for the season, are posted on those high wooden stands keeping everyone safe from drowning, but who is keeping them safe from the sun? Even when the stands have awnings, and they don't always, lifeguards are actually at the highest risk of anyone at the pool for dangerous overheating. If you are a pool owner or manager, one of the best things you can do for employees and customers alike is keeping your lifeguards cool.
