How does one treat a minor heat stroke?

In any heat stroke the body should be cooled immediately. The person should be moved inside, or at least into the shade. Clothing should be removed and cold water, cold cloths or even a cool bath should be used to cool down the patient. If the person appears confused, dizzy or appears to be drunk an ambulance should be called immediately. If the person is able to drink they should drink water. Sports drinks are OK but water is better.

Some people are more susceptible to heat stroke, the old, the sick, the young and people on medication are affected more easily. === === Good answer above -- I disagree on one small point. If the patient enters heat stroke with electrolytes depleted, you're not going to be able to rehydrate effectively until that balance is re-obtained. I like sports drinks for this, as well as Orange Juice (high in potassium) or even salty lemonade.
