People should consume no less than 2, ml of water a day, but there are various sources of water, which can also be obtained from diet. Therefore, if the diet consumes 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 15 ml of water a day.

Consequences of drinking too much water:

1. Drinking too much water will increase the burden on the kidneys. The human body detoxifies through urine, and the main component of urine is water, and all urine is filtered by the kidneys. Therefore, if you drink too much water, it means that the kidneys filter more, which will increase the burden on the kidneys.

2. Drinking too much water can cause water poisoning. The maximum continuous diuresis speed of human kidney is 16 ml per minute. If the amount of water ingested by human body exceeds this standard, or the speed of drinking water exceeds this standard, there will be excess water in the body, which in turn will cause dehydration hyponatremia, which will be manifested as dizziness, vomiting, weakness and rapid heartbeat.

Consequences of drinking too little water:

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

drinking water is a way for living things to take in water through their mouths, and the amount of liquid taken in by human bodies through their mouths is about 2 liters every day. Water is mainly absorbed in the stomach. After entering the human body, water is mainly used to supplement intracellular fluid and extracellular fluid, and participates in various physiological activities of the human body. Therefore, drinking water is an important part of maintaining the metabolism of living beings.

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

water is not only the main component of the body, but also has many physiological functions, mainly divided into two kinds of free water and bound water. The solubility of water is very strong, and many substances can be dissolved in water and dissociated into ionic state, 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 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 can help to dissipate heat. When the weather is cold, because of the great potential of water to store heat, the human body will not be cooled by the cold outside, and the water has great fluidity.

On the one hand, it can transport oxygen, nutrients and hormones, 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 lubricants for corresponding organs.

Adult body fluids are composed of water, electrolytes, low-molecular-weight organic compounds and protein, which are widely distributed inside and outside tissues and cells and constitute the internal environment of human body. Among them, intracellular fluid accounts for about 4% of body weight, and extracellular fluid accounts for 2% (including 5% plasma and 15% interstitial fluid).

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