People should consume no less than 2000 ml of water every day, but the sources of water are diverse and can also be obtained from diet. Therefore, if you eat more water, you can drink less water, and vice versa. Generally, five or six cups a day is more appropriate. Some experts believe that it is more appropriate for ordinary people to drink 1500ml of water a day.

The consequences of drinking too much water:

1, drinking too much water will increase the burden on the kidneys. The human body detoxifies through urine, the main component of which is water, and all urine is filtered by the kidneys. Therefore, drinking too much water means that the kidneys are filtered too much, which will increase the burden on the kidneys.

2. Drinking too much water will cause water poisoning. The continuous maximum diuresis speed of human kidney is 16 ml per minute. If the amount of drinking water exceeds this standard, or the speed of drinking water exceeds this standard, there will be excess water in the body, which will lead to dehydrated hyponatremia, which is manifested as dizziness, vomiting, fatigue, rapid heartbeat and other symptoms.

Consequences of drinking too little water:

Often not drinking water will cause the following reactions: slow metabolism, poor digestion and absorption; Poor transportation nutrition; Poor waste discharge; Not conducive to defecation; Not conducive to antipyretic cooling; Not conducive to the lubrication of joints, muscles and organs; Not conducive to keeping the skin moist; Irritability; Lose vitality; Oliguria.

Drinking water is a way for organisms to absorb water through their mouths. The daily intake of liquid through the mouth is about 2 liters. Water is mainly absorbed in the stomach. After water enters the human body, it is mainly used to supplement intracellular fluid and extracellular fluid, and participate in various physiological activities of the human body. Therefore, drinking water is an important part of maintaining biological metabolism.

How to judge water shortage: If you don't know whether you drink more or less water, here's a tip, which can be judged by the color of your urine. Generally speaking, human urine is light yellow. If the color is too light, maybe they drink too much water. If the color is too dark, it means that more water is needed.

Water is not only the main component of the body, but also has many physiological functions, mainly divided into free water and bound water. The solubility of water is very strong, and many substances can be dissolved in water and dissociated into ionic states, which plays an important role.

Protein and fat insoluble in water can be suspended in water to form colloid or emulsion, which is convenient for digestion, absorption and utilization; Water directly participates in the redox reaction in human body, promoting various physiological activities and biochemical reactions; Without water, it is impossible to maintain physiological activities such as blood circulation, breathing, digestion, absorption, secretion and diarrhea, and metabolism in the body cannot be carried out; Water has a large specific heat, which can regulate body temperature and keep it constant.

When the outside temperature is high or the body generates a lot of heat, evaporation and sweating of water help to dissipate heat. When the weather is cold, because water has great potential to store heat, the human body will not be cooled by the cold outside, and water has great mobility.

On the one hand, it can transport oxygen, nutrients, hormones and so on. On the other hand, it can excrete metabolites and toxic substances through defecation, urination and sweating. Water is also a self-contained lubricant in the body, such as skin moisturizing. Tears, saliva, joint capsule and serous cavity fluid are all lubricants for corresponding organs.

Adult body fluids are composed of water, electrolytes, low molecular organic compounds and protein, which are widely distributed in tissues and cells, forming the internal environment of human body. Among them, intracellular fluid accounts for about 40% of body weight, and extracellular fluid accounts for 20% (including 5% plasma and 15% interstitial fluid).

Water is an essential substance for substance metabolism. Cells must absorb nutrients from tissue fluid, and nutrients can only be fully absorbed if they are dissolved in water. Intermediate products and general end products of substance metabolism must also be transported and eliminated by interstitial fluid.
