人们见了活泼可爱的儿童,常以这孩子长得多水灵之语夸奖;对处于豆蔻年华的少女则以如开放的蓓蕾赞颂其美。而皱纹满面,肌肤枯糙,则是衰老的代名词了。可见,人体健美离不了水。水,生命的摇篮。是水孕育了生命,浇灌着生命之树,才使生命充满了青春般的活力。科学家们测定表明,受精卵发育为胚胎时,水占90%;婴幼儿水分占体重的70%以上;成年人体内水分为70%左右;到了老年期便下降到60%以下。就人体内部来说,占体重4%的血液,含水量达91～93%;肌肉含水75～80%;皮肤含水75%。水是人体必需的营养素,它把各种营养物质、氧、激素和酶运送到各组织细胞,同时将细胞代谢的废物带到有关器官,排出体外。水在体内维持酸碱平衡、调节体温、润滑关节、滋润肌肤等方面,起着举足轻重的作用。拿皮肤来说,如皮肤细胞缺乏水分,会变得干枯无华,出现皱纹,抵抗力下降,易患皮肤病。健与美是有机的整体,失去健康,美也就不存在了。
People saw lively and lovely children, often in the child’s words more salute; praise for the young girl is like an open bud to praise its beauty. The wrinkles, rough skin, it is synonymous with aging. Can be seen, bodybuilding can not live without water. Water, the cradle of life. Water is the birth of life, watering the tree of life, life is full of youthful vitality. Scientists have determined that when fertilized eggs develop into embryos, water accounts for 90%; infants and young children account for more than 70% of body weight; adults have about 70% moisture; and in old age they drop below 60%. In the human body, 4% of body weight of blood, water content of 91 to 93%; muscle water 75 to 80%; skin moisture 75%. Water is a nutrient essential for the body. It carries various nutrients, oxygen, hormones and enzymes to various tissues and cells, and brings the cells’ metabolic waste to relevant organs for excretion. Water in the body to maintain acid-base balance, regulate body temperature, lubricate joints, moisturize the skin, plays a decisive role. Take the skin, such as skin cells lack of water, will become dry, wrinkles, decreased immunity, susceptible to skin diseases. Health and beauty are the organic whole, lose their health, the United States also does not exist.
