Girls, the question is off-topic. My husband overheated yesterday, today his temperature and pulse are bad, naturally he's not going to the hospital, but since this morning I noticed that he's burning up, 38* what can I give him? Or will it pass in a couple of days? He has never had a heat stroke before, I don't even know how to help.
