And our friends Heat Exhaustion and Heat Stroke will want to pay a visit. Don’t let them. Avoid overexerting yourselves and if possible, stay the hell away from the sun from 10 AM till at least 2 PM.
Cool off the head. Cold compresses to the back and top of the skull should help. One in each armpit and one below the sternum should help lower inner core temps. But if you suspect the damage is worse, seek help right then and there. Intravenous might be necessary.
