Baton Rouge, La (NBC33) — With temperatures ticking up toward 100 degrees almost every day this week, medical professionals are reminding you to stay cool and hydrated.

They say those most at risk are the elderly, small children and the mentally ill.

Nurse practitioner Todd Genre says the most important thing to do is stay hydrated.

"It's always best to take breaks when you can, in the shade or an air-conditioned building,” stated Genre. “You can wear light-colored, loose fitting clothing and drink between two and four drinks an hour, whether it's water or sports drinks."

He says there are some clear signs that someone is suffering from heat stroke - they include confusion, trouble walking, passing out and muscle cramps. If someone is experiencing those symptoms, head to the hospital immediately.
