Therefore, today, how to keep healthy scientifically is very important. There is an old Chinese saying that "tonic medicine is better than tonic food, tonic food is better than tonic water, and water is the king of all medicines". Health preservation should begin with "drinking water".
Health is the basic guarantee of quality of life. Science has proved that 15% of human health comes from heredity and 85% from environmental factors. Diet is the most important and daily material factor in environmental factors.
Chinese diet includes two aspects, one is drink, the other is food. The word "water" in "diet" comes first. The origin and breeding of life are inseparable from water. There are creatures on earth that don't need sunlight, creatures that don't need oxygen, but absolutely no creatures that don't need water.
If people don't eat, they can still survive for several weeks; But if you don't drink water, you will dehydrate and die in a few days. More than two thirds of our body is water. Water itself is the most important nutrient, which can not be replaced by any drink.
Because water is easy to get, it is often ignored in daily life. In fact, water is an important macro nutrient in human body, accounting for about 70% of human body weight.
Nutrients, also known as nutrients, can be divided into three categories according to their physiological functions: structural nutrients - protein, fat, carbohydrate, macro minerals, etc; To regulate and control nutrients such as vitamins, trace elements, hormones, etc; The medium nutrient -- water.

Water is the medium of structural nutrients, regulating the metabolism of nutrients in human body and the carrier of metabolites.
Water is a physiological River, in which the nutrients needed to maintain life navigate in their respective metabolic pathways.
Without water, all the other nutrients are like dry sand on a dry river bed. When the water loss reaches 2% of the body weight, people will feel thirsty. When the water loss reaches more than 6%, people will feel fatigue, depression and anuria. When the water loss is more than 20% and can not be supplemented, they will not be able to carry out normal physiological activities such as oxidation-reduction, decomposition and synthesis, which will endanger their lives.
Water is mainly responsible for digesting food, transporting nutrients, keeping joints and internal organs moist, and regulating body temperature. When there is enough water, all tissues of the human body can work effectively. However, when water shortage occurs, it can lead to physical pain, tissue damage and various health problems.
According to research, symptoms such as asthma, allergies, high blood pressure, high cholesterol, headache and periodic migraine can be alleviated or even cured by drinking enough water.
Eight preventive functions of water:
1. Water can prevent heart disease and cerebral vascular obstruction.
2. Water can prevent obesity and lose weight. 3. Water can prevent the deposition of multiple crystal salts in urine.
4. Water has the effect of sterilization and detoxification, can reduce the incidence of cancer.
5. Water helps reduce stress, anxiety and depression.
6. Water is the regulator that makes natural sleep.
7. Water is the best lubricant for defecation.
8. Water can prevent joint stiffness and restore muscle function.
Water is the king of all kinds of medicine --- food is the God of the people, and water is the priority of food. Tonic is better than tonic, tonic is better than water, water is the king of medicine, water is the first nutrition!
