Talking about water and people

The importance of water to human beings is self-evident. No matter what life on the earth can't live without water, water is an important resource of life. 60% ~ 70% of human body weight is water. If the water volume is reduced by 65,438+00%, people will feel very uncomfortable. For example, will you feel a little uncomfortable and thirsty after exercise, and you will only be full if you replenish water? If we subtract 65,438+00% from this, the daily water demand of an adult is about 2500ml, but everyone's demand for water is different, and according to some characteristics of people, such as gender, age, weight and labor intensity, the demand for water is also very different, because everyone's physiological and pathological conditions are different, so the demand for water varies from person to person. In addition, about 5% of minerals in the human body are ingested through water intake.

Water plays an important physiological role in human body, because water is the best substance for most substances to circulate and ionize in human body. Physiological effects of water on human body.

1 participates in the whole process of metabolism in human body. Water plays a role in transporting oxygen and carbon dioxide, as well as in the process of digestion (drinking soup before meals is better than medicinal soup), nutrient circulation and excretion in the body (so people with constipation will be told by doctors to drink more water). These are mainly transported by water, and these physiological activities are inseparable from the medium of boiling water, so that metabolism and physiological reactions in the human body can proceed smoothly.

2. Water is an important part of cells and body fluids. It can be said that every cell, every tissue and organ of the human body contains water, and the products secreted by various glands of the human body are basically liquid. If the body is short of water, the secretion of digestive juice will be reduced, and food digestion will be affected, which will lead to a series of loss of appetite (excessive water loss in hot summer) and reduced metabolic activities.

Water plays an important role in lubricating human joint muscles and some internal organs. This lubricity plays a certain protective role in a certain sense, and can play a role in buffering and reducing friction for various organs of the human body, such as joints, muscles and tissues, thus further playing a protective role and ensuring the normal functions of the above organs.
