Health Report.We talked last week about waysto avoid cold-weather injuries.Today we are going to talk aboutemergency treatment of hypothermia.Hypothermia can be mild,moderate or severe.Mild hypothermia is somethingthat most people in cold climateshave experienced at one time or another.You feel so cold that your bodystarts to shake -- not very much,but uncontrollably.The treatment for mild hypothermiastarts with getting out of the cold and,if necessary, changing into dry clothes.Drinking warm, non-alcoholic liquidsand eating something sugarycan stop the shivering.Taking a warm bath or sittingby a fire or doing some exercisecan also help the body warm up.These are all common-sense treatments.But treatment needs to changewhen people enter the moderateor severe stages of hypothermia.In that situation,their body temperature dropsbelow thirty-five degrees Celsius.They lose the ability to think clearly.Their muscles become stiff.They might bump into thingsor fall over objects.Members of search-and-rescue teamswill first try toprevent additional heat loss.They will place extra coveringaround the chest, head and neckof hypothermia victims to keep them warm.Hypothermia victims needmedical help as soon as possible.Working quickly to get peopleout of the cold is important.However, hypothermia victimsmust be moved slowly and gently.Any rough or sudden movementcan force cold blood from the arms,legs and hands deep intothe warmer middle of the body.This sudden flow of cold bloodcan create shock, a serious condition.It can also cause an abnormal heartbeat.Members of search-and-rescue teamshave a saying that hypothermia victimsare not dead until they are warm and dead.The process of "rewarming" a person needsto be done slowly, in a hospital setting.An extremely low body temperaturecan cause the heart to beat so slowlythat a pulse may be difficult to find.In other words, a personwho is suffering from the effectsof severe cold may seem dead,but still be alive.And that's the VOA Special EnglishHealth Report,written by Caty Weaver.If you missed last week's adviceabout how to avoid cold-weather injuries,you can find it at 51voa.com.We also invite you to share your storiesof the coldest weather-- or the hottest weather-- you have ever experienced.You can share your storieson Facebook and Twitterat VOA Learning English.
