Extreme weakness, profuse sweating, and abdominal cramps are all symptoms of heat exhaustion, and if they aren't taken care of they could lead to heat stroke.
Now that summer is just around the corner, the temperatures are on the rise. So according to Dr. Earl Reisdorff of Ingham Regional Medical Center, it's important to stay hydrated.
"If you sweat you should drink fluids. Heat exhaustion isn't deadly. It can make you really sick, but it can turn into heat stroke, and that's fatal."
If you notice any symptoms of heat exhaustion, make sure you drink plenty of fluids until you feel better. Also, you should get indoors where it is cool.
