在成人体内，60~70%的质量是水。儿童体内水的比重更大，可达近80%。如果一个人不吃饭，仅依靠自己体内贮存的营养物质或消耗自体组织，可以活上一个月。但是如果不喝水，连一周时间也很难度过。体内失水10%就威胁健康，如失水20%，就有生命危险，足可见水对生命的重要意义。水是我们每天都离不开的，但是，你知道应该怎样正确喝水吗？应该每天喝多少水？下面我们就来听听专家的建议吧！
In adults, the mass of 60~70% is water. The proportion of water in children is more than 80%. If a person does not eat, it can live for a month by relying only on the nutrients stored in his body or using the autologous tissue. But if you don't drink water, it's difficult for a week. 10% of the loss of water in the body is a threat to health, such as 20% of the loss of water, the danger of life, and the significance of water to life. Water is the one we can't do every day, but do you know how to drink the water right? How much water should I drink every day? Let's listen to the advice of the experts.
水还有治疗常见病的效果，比如：清晨一杯凉白开水可治疗色斑；餐后半小时喝一些水，可以用来减肥；热水的按摩作用是强效的安神剂，可以缓解失眠；大口大口地喝水可以缓解便秘；睡前一杯水对心脏有好处；恶心的时候可以用盐水催吐。
The water and the treatment of common diseases, such as: in the morning a cup of cold white boiling water can treat splash; half an hour after a meal to drink some water, can be used to lose weight; massage with hot water is a powerful sedative, can alleviate insomnia; drink Dakoutaikou can relieve constipation; before a cup of water is good for the heart sick; you can use brine emetic.
1、溶解消化功能
1. Dissolve digestion function
水是体内一切生理过程中生物化学变化必不可少的介质。水具有很强的溶解能力和电离能力（水分子极性大），可使水溶性物质以溶解状态和电解质离子状态存在，甚至一些脂肪和蛋白质也能在适当条件下溶解于水中，构成乳浊液或胶体溶液。溶解或分散于水中的物质有利于体内化学反应的有效进行。
Water is an essential medium for biochemical changes in all physiological processes in the body. Water has very strong solubility and ionization ability (water molecule polarity), can make the water soluble substances exist in dissolved state and ionic state, and even some fat and protein can also under appropriate conditions, dissolved in water, composed of emulsion or colloidal solution. The dissolved or dispersed substances in the water are beneficial to the effective chemical reactions in the body.
食物进入空腔和胃肠后，依靠消化器官分泌出的消化液，如唾液、胃液、胰液、肠液、胆汁等，才能进行食物消化和吸收。在这些消化液中水的含量高达90%以上。
The food enters the cavity and gastrointestinal digestion, rely on the secretion of the digestive organs, such as saliva, gastric juice, pancreatic juice, intestinal fluid, bile, to food digestion and absorption. In these digestive fluids, the water content is up to 90%.
2、参与代谢功能
2. Participate in metabolic function
在新陈代谢过程中，人体内物质交换和化学反应都是在水中进行的。水不仅是体内生化反应的介质，而且水本身也参与体内氧化、还原、合成、分解等化学反应。水是各种化学物质在体内正常代谢的保证。
In the process of metabolism, material exchange and chemical reaction in the body are carried out in the water. Water is not only the medium of biochemical reaction in the body, but also the water itself is involved in the chemical reactions such as oxidation, reduction, synthesis and decomposition in the body. Water is the guarantee of the normal metabolism of various chemicals in the body.
如果人体长期缺水，代谢功能就会异常，会使代谢减缓从而堆积过多的能量和脂肪，使人肥胖。
If the human body is short of water for a long time, the metabolic function will be abnormal, which slows down metabolism and accumulates too much energy and fat to make people fat.
3、载体运输功能
3, carrier transport function
由于水的溶解性好，流动性强，又包含于体内各个组织器官，水充当了体内各种营养物质的载体。在营养物质的运输和吸收、气体的运输和交换、代谢产物的运输与排泄中，水都是起着极其重要的作用。比如，运送氧气、维生素、葡萄糖、氨基酸、酶、激素到全身；把尿素、尿酸等代谢废物运往肾脏，随尿液排出体外。
Water is a carrier of various nutrients in the body because of its good solubility and fluidity, which is also contained in various tissues and organs of the body. Water plays an extremely important role in the transport and absorption of nutrients, the transport and exchange of gases, and the transport and excretion of the metabolites. For example, transport oxygen, vitamins, glucose, amino acids, enzymes, hormones to the whole body, urea, uric acid and other metabolic wastes transported to the kidneys, and excreted with urine.
4、调节抑制功能
4. Regulation of inhibitory function
水的比热高，对机体有调节体温的作用。
The water has a high specific heat and has a role in regulating body temperature.
防止中暑最好的办法就是多喝水。这是因为认为摄入的三大产能营养素在水的参与下，利用氧气进行氧化代谢，释放能量，再通过水的蒸发可散发大量能量，避免体温升高。当人体缺水时，多余的能量就难以及时散出，从而引发中暑。
The best way to prevent heat stroke is to drink more water. This is because we believe that the intake of three major production nutrients is based on the participation of water. Oxygen is used to oxidize metabolism, release energy, and then evaporate a lot of energy through water evaporation to avoid rising body temperature. When the body is short of water, the excess energy is dissipated in time, causing heatstroke.
此外，水还能够改善体液组织的循环，调节肌肉张力，并维持机体的渗透压和酸碱平衡。
In addition, water can also improve the circulation of body fluid tissue, regulate muscle tension, and maintain the body's osmotic pressure and acid-base balance.
5、润滑滋润功能
5, lubricating and moistening function
在缺水的情况下做运动是有风险的。因为组织器官缺少了水的润滑，很容易造成磨损。因此，运动前的1个小时最好要先喝充足的水。
It is risky to exercise in the absence of water. Because the tissues and organs are lack of water lubrication, it is easy to cause wear. Therefore, it is best to drink enough water for 1 hours before exercise.
体内关节、韧带、肌肉、膜等处的活动，都由水作为润滑剂。水的黏度小，可使体内摩擦部位润滑，减少体内脏器的摩擦，防止损伤，并可使器官运动灵活。
Water is used as a lubricant for the activities of joints, ligaments, muscles and membranes in the body. The viscosity of water is small, it can make the body friction parts lubricate, reduce the friction of the body organs, prevent the damage, and make the organ movement flexible.
同时水还有滋润功能，使身体细胞经常处于湿润状态，保持肌肤丰满柔软。定时定量补水，会让皮肤特别水润、饱满、有弹性。可以说，水是美肤的佳品。
At the same time, the water also has a moisturizing function, so that the body cells are often in a wet state, keeping the skin plump and soft. Timed quantitative water replenishment will make the skin moist, full and elastic. It can be said that water is the beauty jiapin.
6、稀释和排毒功能
6, dilution and detoxification
不爱喝水的人往往容易长痘痘，这是因为人体排毒必须有水的参与。没有足够的水，毒素就难以有效排出，淤积在体内，就容易引发痘痘。
People who do not love to drink water tend to be prone to acne, which is because the human body detoxification must have water. Without enough water, the toxin can not be effectively discharged, silting in the body, it is easy to cause acne.
其实，水不仅有很好的溶解能力，而且有重要的稀释功能，肾脏排泄水的同时可将体内代谢废物、毒物及食入的多余药物等一并排出，减少肠道对毒素的吸收，防止有害物质在体内慢性蓄积而引发中毒。因此，服药时应喝足够的水，以利于有效地消除药品带来的副作用。
In fact, water not only has a good solubility, and dilution function important, at the same time, the renal excretion of water can be metabolic wastes, toxins and excess ingestion of drugs be discharged, reduce the intestinal absorption of toxins, prevent the accumulation of harmful substances in the body and lead to chronic poisoning. Therefore, when taking medicine, we should drink enough water to effectively eliminate the side effects of the drug.
应该怎样正确喝水？
How should you drink the water correctly?
经常少量多次饮水，不要等到口渴时一次大量饮水，因为口渴时体内已经丢失了2-3杯的水分。不要低估排汗损失的水量。注意尿液的颜色和气味，量少色深表示身体已经处于脱水状态。不要用咖啡、茶、苏打水或酒精饮料代替水。咖啡因和酒精有利尿作用，会增加水分的丢失。 睡眠时身体也会丢失水分。在一天开始和结束时都应饮一杯水。 天热时，凉开水是保持体内水分的最好液体。凉水比热水吸收更快，冷却身体更有效，同时可减少出汗。
Often a small amount of drinking water, do not wait for thirst when a large amount of water, because of thirst in the body has lost 2-3 cups of water. Do not underestimate the amount of water that is lost by sweating. Pay attention to the color and smell of the urine. The amount of less color indicates that the body is in a dehydrated state. Do not replace water with coffee, tea, soda or alcoholic beverages. Caffeine and alcohol have diuretic effects, which can increase the loss of water. The body also loses water during sleep. Drink a cup of water at the beginning and end of the day. When it's hot, cool water is the best liquid to keep water in the body. Cool water is faster than hot water, cooling the body more efficiently and reducing sweating.
功能水 通过一定技术处理改变了水的理化性质，并提升了水有益健康的功能，这种水就是功能水。目前市场上有添加了各种有益健康的活性化合
Functional water changes the physical and chemical properties of water and improves the healthy function of water, which is functional water. There are all kinds of healthy active compounds on the market.
