Dehydration(체내탈수현상)-체내 수분 부족은 위험신호 jdoe |
|
The Elderly : Older people are especially prone to dehydration, mostly because they do not drink as much fluid as they should. One should always take in enough water to prevent thirst. Waiting until one is thirsty to drink indicates that the person is already in need of fluid replacement.
Cold water is more refreshing than water that is at room temperature. Coffee, soft drinks containing caffeine and tea have diuretic effects and cause further dehydration. Many elderly persons do not
drink sufficiently because they are afraid of incontinence.
Athletes : Sweating is the major protective mechanism for cooling the body. However, sweat cannot evaporate to cool the body properly when the air outside is humid. Thus, individuals who overexercise in hot, humid weather can become severely dehydrated and overheated as a result. Sweat contains such substances as sodium, chloride, potassium and other electrolytes. Thus, water alone is not as helpful for dehydration of athletes in hot humid places. Sports drinks contain these electrolytes. They also contain carbohydrates to help fuel the muscular activity during athletic events.< 저작권자 © 약국신문 무단전재 및 재배포금지 > |
