LOUISVILLE, Ky. (WDRB) -- A new law in Indiana will help student-athletes stay safe in hot weather.

Fox 59 reports that starting July 1, all school and intramural coaches will have to pass a "heat preparedness" course. Coaches will learn the signs of heat exhaustion and other illnesses.

Many say the new requirements will help coaches take a step back and decide when a player needs to sit out to cool off.

Fishers High School tennis coach Dave Hefferen said he and his athletes need to know when they are over-heating.

"We know if you're thirsty, you're already dehydrated," he said. "So you need to keep the fluids coming in. I don't think it's a mark of machoism anymore. I think if you don't take care of it, it's more of a mark of stupidity as a coach. You'd better watch what you're doing."

The heat preparedness course is already offered by the Indiana High School Athletics Association, and many coaches have already completed the training. The law will make that training a requirement.

Coaches will have to compete the heat preparedness certification every two years.
