ROCHESTER, Minn. - With dangerous heat occurring this week, more are taking to the pools. With this, more lifeguards are on standby to make sure everyone is staying safe. Many do not realize how much goes into making sure these lifeguards are safe as well. "We actually provide snacks and fruits and pretzels and Gatorades and things like that to try to help encourage their hydration," said Whitney Benedetti, the Aquatics Director at the Rochester Athletic Club.
