Marcus overworked his muscles and it’s dehydrated. What is he at risk getting ?

How do you treat it ?

Heat Stroke ( I think)

At home treatment options:

Get to a shady or air-conditioned place. If you don't have air conditioning at home, go someplace with air conditioning, such as the mall, movie theater or public library.Cool off with damp sheets and a fan. If you're with someone who's experiencing heat-related symptoms, cool the person by covering him or her with damp sheets or by spraying with cool water. Direct air onto the person with a fan.Take a cool shower or bath. If you're outdoors and not near shelter, soaking in a cool pond or stream can help bring your temperature down.Rehydrate. Drink plenty of fluids. Also, because you lose salt through sweating, you can replenish salt and water with some sports drinks. If your doctor has restricted your fluid or salt intake, check with him or her to see how much you should drink and whether you should replace salt.Don't drink sugary or alcoholic beverages to rehydrate. These drinks may interfere with your body's ability to control your temperature. Also, very cold drinks can cause stomach cramps.
