How much water does the human body contain, and what is the water content of the human body?

The proportion of water in the human body is about 70%, and the water in the body needs to be completely replaced in about 5 days.

Remember.

How to drink water scientifically2007-05-27 11:48Drinking two glasses of water in the morning is the most effective way to replenish the body's water loss. Drink clean water and don't replace plain water with beverages.

Don't wait until you're thirsty to drink water, drink it often one sip at a time. Drink two glasses two hours before exercising, drink at least half a glass of water every 15 minutes during exercise, compare your weight before and after exercise, and drink 2 glasses of water for every kilogram you lose. In general, the amount of exercise and the duration of exercise should not exceed 90 minutes, and the body will not lose electrolytes and minerals, so drink only water.

If you are outdoors, especially in summer, and exercise vigorously for more than 90 minutes, you can add diluted fresh fruit juice to water to speed up the replenishment of electrolytes, sugar and lost water, but avoid high-sugar beverages (such as soft drinks), as high sugar can affect the speed at which the body absorbs water. Drinking water should pay attention to the best time, after getting up in the morning to drink more water in moderation, can compensate for the loss of water overnight, and at the same time to prevent hypertension, cerebral hemorrhage, cerebral thrombosis formation also has a certain effect, drinking water at about 10 o'clock in the morning can supplement the water lost due to sweat and urination, drinking water at 3 o'clock in the afternoon can effectively replenish sweat, urine and other water loss due to excretion, and the waste hoarded in the body will be smoothly carried out, drinking water around 8 o'clock in the evening is considered the most suitable time, Because the blood concentration increases during sleep, drinking water can dilute the blood and speed up blood circulation.

About 55%-60% of adult males and 60-65% females, and the proportion of water content decreases with age.

Water content of the human body:

1. The water content of each organ in the human body is different. Water is 75% of the brain, 75% of the pontine, 86% of the lungs, 86% of the liver, 83% of the kidneys, 75% of the muscles, 94% of the blood, 80% of the cartilage, and 50% of the connective tissue.

2. Even 10% of fat cells and fat molecules are water. As long as the body lacks 1% 2% water, the organs do not get enough water and nutrients, and the brain soaked in cerebrospinal fluid can lose as little as 1% water can lead to fatal consequences.

In infancy, the water content of the body can reach 72%, and in adulthood, the water content of water drops to about 65%. In the course of one's life, the amount of water in the body gradually decreases as people age.

There are 8200 ml of water in the human body every day, which is secreted by the oral cavity and gastrointestinal secretory glands into the gastrointestinal tract (such as saliva, intestinal juice, pancreatic juice, etc.), and the vast majority of this water (about 800 ml) is returned to the bloodstream from the ileum and colon**. As a result, patients with vomiting and diarrhoea are prone to losing water and becoming dehydrated. Water in the human body is the main component of tissue cells, accounting for about 50% of the human body closure type.

The rest of the water is in the blood and intercellular spaces, and a small amount of transfect water is present in the empty organs.
