“只要有水,生存7天以上没问题。”在四川汶川大地震营救队伍中,担任陕西省医院救护医疗队副领队的骨科主任凌鸣说。凌鸣还说:“对废墟中的人来说,水是最重要的。在没有水的情况下,人在3天后会比较危险。如果有水,即使没有食品,7天以后也能生存下来。”在这次大地震中,许多人在废墟下就是靠的一点水,有的甚至还喝自己的尿,再加上坚强的求生信念而等到解放军官兵营救生还,可以看出水对人体生命的重要性。水是生命的基础,是人体的生命之源。水是人体内含量最多的成分,体液占人体重的70%左右,是维持人体正常生理机能所必需,失掉15%的水,生命就有危险。以身体内水分的含量计算,最多的是脑脊髓,约占99%;其次为淋巴腺,约占94%;血液中的水分约占83%;肌肉中的水分约占77%;骨骼中的水分约占20%。以上是指成年人,婴孩体中的水分约占体重的80%。水对人体的生理作用主要有帮助消化、排泄废物、润滑关节、平衡体温、维持细胞机能、保障淋巴、血液等组织的代谢等作用。人们平时谈论和讲究的是怎样吃,知道食物要荤素、粗细、软硬搭配,就餐要有规律,要定时定量,才能吃出营养和健康,而往往忽视了怎样饮水,如何科学饮水。在我诊治的病人中,就有多例因平时不能科学饮水而引发的各种疾病,严重损害了身体的健康,更谈不上健身了。所以说,科学饮水对人的身体健康很是重要。
“As long as there is water, no problem for more than 7 days to survive. ” Ling Wenchuan earthquake rescue team in Sichuan Province, Shaanxi Province Hospital ambulance team assistant team leader Ling Ming said. Lingming also said: “Water is the most important for people in the rubble. In the absence of water, people are more dangerous in three days. If there is water, even without food, it can survive for seven days Down. ”" In this earthquake, many people rely on the rubble under the rubbish, and some even drink their own urine, coupled with a strong belief in survival until the People’s Liberation Army soldiers survived, we can see that water on the human body The importance of life. Water is the basis of life, is the source of human life. Water is the most abundant component of human body, body fluid accounts for about 70% of body weight, is necessary to maintain the body’s normal physiological function, the loss of 15% of water, life is at risk. Calcium content in the body, the most is the brain and spinal cord, accounting for about 99%; followed by the lymph gland, accounting for about 94%; about 83% of the water in the blood; muscle moisture accounts for about 77%; bone Moisture accounts for about 20%. Above refers to adults, baby’s body water accounts for about 80% of body weight. Physiological effects of water on the human body are mainly to help digestion and excretion of waste, lubrication joints, body temperature balance, maintaining cell function, protection of lymphatic, blood and other tissue metabolism and so on. People usually talk about and pay attention to how to eat, know the food to meat and vegetables, thickness, with hard and soft, have regular meals, regular quantitative, in order to eat nutrition and health, but often overlooked how to drink, how to drink water scientifically. In my diagnosis and treatment of patients, there are many cases due to the usual non-scientific drinking water caused by a variety of diseases, severely damaged the health of the body, let alone fitness. Therefore, scientific drinking is very important to human health.
