A person’s daily intake of water should be no less than 2000 ml. However, water comes from various sources and can also be obtained from the diet. Therefore, if the diet contains a lot of water, you can drink less water, and vice versa. Drink some. Generally, five or six cups a day is more appropriate. Some experts believe that it is more appropriate for the average person to drink 1,500 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. 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 will filter more , which will increase the burden on the kidneys.
2. Excessive drinking of water can cause water intoxication. The continuous maximum diuretic rate of the human kidney is 16 ml per minute. If the amount of water ingested by the human body exceeds this standard, or the speed of drinking water exceeds this standard, there will be excess water in the body, which will lead to dehydration and low sodium. Symptoms include dizziness, vomiting, weakness, and rapid heartbeat.
Consequences of drinking too little water:
Regularly not drinking water will cause the following reactions: slowed metabolism, poor digestion and absorption; poor nutrition transportation; poor excretion of waste; It is unfavorable for defecation; it is not conducive to antipyretic and cooling; it is not conducive to lubricating joints, muscles and organs; it is not conducive to keeping skin moist; it is irritable; it is loss of vitality; it is oliguria.
Drinking water is a way for living organisms to absorb water through the mouth. The human body absorbs approximately 2 liters of liquid through the mouth every day. Water is mainly absorbed in the stomach. After entering the human body, water is mainly used to replenish intracellular and extracellular fluids and participate in various physiological activities of the human body. Therefore, drinking water is an important part of maintaining the metabolism of a living body.
How to judge water shortage: If you don’t know whether you are drinking too much or too little water, here is a little tip. You can judge it based on the color of your urine. Generally speaking, human urine is light yellow. If the color is too light, it may be due to drinking too much water. If the color is dark, it means that more water is needed.
Water is not only the main component of the body, but also has many physiological functions. It is mainly divided into two types: 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 to play important roles.
Water-insoluble proteins and fats can be suspended in water to form colloids or emulsions, which facilitate digestion, absorption and utilization; water directly participates in redox reactions in the human body, promoting various physiological activities and biochemical reactions. Without water, physiological activities such as blood circulation, respiration, digestion, absorption, secretion, and diarrhea cannot be maintained, and metabolism in the body cannot proceed; water has a large specific heat and can regulate body temperature and keep it constant.
When the outside temperature is high or the body produces a lot of heat, evaporation of water and sweating can help dissipate heat. When the weather is cold, because water has a very large potential to store heat, the human body will not lower its body temperature due to the cold outside, and the fluidity of water is high.
On the one hand, it can transport oxygen, nutrients, hormones, etc., and on the other hand, it can excrete metabolites and toxic substances through stool, urination, and sweating. Water is also the body's own lubricant, such as skin moisture and tears, saliva, joint capsule and serosal cavity fluid are all lubricants for corresponding organs.
Adult body fluids are composed of water, electrolytes, low-molecular organic compounds, and proteins. They are widely distributed inside and outside tissue cells and constitute the internal environment of the human body. Intracellular fluid accounts for about 40% of body weight, and extracellular fluid accounts for 20% (of which plasma accounts for 5% and interstitial fluid accounts for 15%).
Water is an essential substance for the metabolism of the body. Cells must absorb nutrients from the interstitial fluid. Only when nutrients are dissolved in water can they be fully absorbed. Intermediates and final products of substance metabolism must also pass through Interstitial fluid transport and elimination.
