(2016·河北邢台市摸底考试)Sunstroke is a condition that can quickly go from dangerous to deadly，especially if proper care isn't given immediately.

Sunstroke，sometimes called heatstroke，is a result of the body temperature rising above the safe limit.This causes the body's necessary functions to stop working.

It's usually pretty easy to avoid sunstroke，as long as proper action is taken.In that case，you need to act as quickly as possible to return that person's body to a safe temperature.Here are a few tips to help treat sunstroke.

Call for help

Call to get an ambulance as quickly as possible.This should be the first thing you do，especially if the sunstroke person has fainted (昏倒).Also，call for help from anyone nearby if you're in a public place.If there's no one around，call someone nearby if they can get there sooner than an ambulance.Ask everyone to bring you as much water as possible，if there isn't much nearby.

Get the person to a cooler area

If there's a building nearby，aim for that.Anywhere with plenty of air conditioners and water is perfect.If a building isn't available，bring the person to a well­shaded area.

Get the water flowing

If the person is still conscious，get him or her to drink water.If there's a bathtub available，fill it with cool water and put the person in it.

If your water supply is limited，you have to save it.Dampen a towel or shirt and put it on the person's body.Focus on the face，neck，and chest.

Fan the person

Getting moving air over the person cools him or her down.Use anything，a towel or sheet，a shirt，your hands，or a piece of board.This is where having many people around really helps，as they can combine to fan the entire body.
