Humans can live for a few days by drinking water, while humans can live for a few days by drinking o

Because man is made of water! Most of the body's operations depend on blood to transport oxygen, and most of blood is made up of plasma Plasma is made up of water! And the cytoplasm is also mostly made up of water!

If there is a lack of water, brain function will decline, cells will shrink, blood will dry up, and people will consume water every minute and every second, so water is very important to people! 3 days without drinking is enough to kill Generally speaking, in scientific medicine, it is normal to say that it is like this, and it will die, but there are exceptions. About one per 1,000 people can be more than a day or two, and water is the most abundant component in the human body.

With just 15% of the water lost, lives are at risk. Nothing plays a more important role in the food we eat through our mouths than water. Without food, we can survive for 2 to 3 weeks, and without water, we will die of dehydration in a few days.

In the predicament of being isolated and helpless, as long as there is water, life will be maintained for a long time; If you can't eat when you're sick, you need to drink water first. Dry mouth is a signal of the body's need for water, and we often drink water at this time. In fact, it's our body that is dehydrated.

This bad habit of drinking water only with a dry mouth leads to frequent dehydration of our body, which is harmful to our health. To sum up, the physiological functions of water mainly include: digesting food, dissolving nutrients with body fluids, transporting nutrients to various tissues, and undertaking the task of absorption and transportation; Excretion of waste products produced by human metabolism; Maintain cell morphology and improve metabolism; Adjust the viscosity of body fluids and improve the circulation of body fluid tissues; Regulates the body's body temperature and maintains the highest moisture and elasticity.

Therefore, the best thing to do is to drink water at the right time to avoid dehydration. Otherwise, the body will be deprived of water on a regular and continuous basis, and the metabolism will not be able to proceed smoothly, and the body's functions will gradually decline. Medical experts consider the needs of the human body and believe that the average daily intake of liters is appropriate.

The water that the human body needs is obtained first from drinking water, and only then from food. When sufficient water is consumed, the circulation of blood and lymphatic fluid will appear in good condition. In this way, it can ensure the supply of nutrients needed by the body, and can dissolve waste products and eliminate toxins, thereby improving the function of internal organs** and moisturizing and smooth.

This is necessary for the health of young people and young children, and is especially important for the elderly. Because the human body has certain material and energy reserves, such as glycogen, fat, etc., short-term non-eating can maintain the needs of life activities; However, water in the human body cannot be stored in large quantities (otherwise everyone will be edema), and water itself has important physiological functions, such as the dissolution and transportation of substances; Maintain the intrinsic posture of cells and organisms (plants will wilt due to lack of water, and people will wrinkle when they lack water**; regulating the temperature (through the evaporation of water); Involved in metabolism (many biochemical reactions need to be carried out in aqueous solution, and some reactions have water as a reactant, such as protein hydrolysis, etc.).Water is often overlooked, but it is the most basic nutrient needed by the human body, representing life, health, youth and vitality.

In this case, we should develop the habit of drinking the right amount of water every day to avoid dehydration.

Scientists have shown that people can live only five days without sleeping, seven days without drinking water, and 20 days without eating.

People can generally live for about 1 month without eating and drinking water, but some studies have also shown that they can live for up to 3 months, but it is only a limit of research and challenges, and it is not recommended to conduct trials in the population.

Normally, the nutrients that a person needs each day include glucose, fat, protein, electrolytes and water. When people don't eat, they can't provide the nutrients mentioned above.

In the absence of sugar intake, the human body relies on the fat and protein in the body to provide energy, and burns the fat in its own body or burns protein as a calorie.

However, drinking water alone can ensure hydration, but it cannot ensure electrolyte intake, and after a long time, the patient will have cachexia, severe consumption, electrolyte imbalance, and eventually death.

Water is a solvent with very good solubility. Oxygen can be dissolved in water, food can only be absorbed when dissolved in water, and waste can only be excreted in water. Without water, nutrients in the body cannot reach the cells and are kept out.

That's why "dehydration" can be fatal. Water is the solvent of all food, vitamins, amino acids, nucleic acids, glucose and minerals, all nutrients and metabolic wastes in the body.

If you are in good health and have good muscle and fat reserves, you can survive for 45 days or more if you only drink water and skip meals. When a person is completely fasting and only drinking water, he begins to break down protein and fat to produce glucose after a few hours of fasting, and after 24 hours, the glycogen disappears, and the energy** depends entirely on burning protein and fat. Due to the human body's protein protection mechanism, protein decomposition is inhibited, and after 3 days of fasting, energy** shifts to fat decomposition to produce ketone bodies.

After 7 days, energy expenditure is almost entirely dependent on ketone bodies. If fasting continues, the amount of fat stored in a person determines how long they can survive after a complete fast. However, when the fat disappears and finally turns to burning the body's structural proteins, the protein is quickly consumed, and the function of the vital organs will fail and die.

Water is not nutritious, although the human body can not do without water, but only drinking water without eating staple food is not able to survive, if only drink water, then at most ten days people will not be able to stand it.

Water has some nutrients in it, but it is not rich in nutrients, and there are not many of them.

Humans can sustain seven days of life if they drink only water, but if they don't drink water, they can only feed their dogs for three days with only food.

Water is one of the six major nutrients, and it is also nutritious, if you only drink water, you can last for 67 days, and no more.

Ordinary water has no nutrients, even mineral water only has trace minerals and trace elements, and cannot replace the nutrients that the human body needs.

In general, if a person only drinks water and no food, he can only last for seven to ten days.

Although water is not nutritious, it provides our body with the necessary water, and if we only drink water, then it can last for six or seven days.

Water is not nutritious, it only contains certain minerals, if people only rely on water to sustain life, they will not be able to live for long, because we need a lot of energy to maintain the needs of the human body.

Water is nutritious, water is a substance that nourishes cells, and it is a substance that constitutes intercellular fluid, so it is said that only water can live for many days, and it can be verified for 7 days without water.

Water is nutritious, but you can't just drink water every day, you also need to add other nutrients, and you can drink only water for a maximum of seven days.

Who has nutrition? How many days can you live if you only drink water? There is no nutritional depreciation that provides your body with essential water, and if it only drinks water, it generally only lives for about seven days.

Water is the source of life, water is rich in minerals, although we drink water that day, feel that water is very common, but the value of water is you can't think of, people can not eat, but can not not drink water, there is water can live.

Who has nutrition? How many days can a person live if he only drinks water? Man only drinks water. If it's a woman, it may last two days longer than a man. But about five days.

Water is the source of human life, why, remember Wenchuan Da**, ** people drank urine in order to survive, so it can be seen that the power of water is great.

If you just drink water, you can't do it, and if you don't eat, it's definitely not nutritious.

Is water nutritious? How many days can a person live if he only drinks water? When I say water, I don't mean that it is nutritious, but that water is indispensable for human beings, and if people leave, water will not live, and if people only drink water, they will not live for a few days, a week or so.

If people only drink water under extreme conditions, then life can last for a long time.

People can last 4-5 days without drinking water and not eating, and they can not consume too much physical strength.

In fact, I think that as children and grandchildren, but when the old man is alive, we should be filial to the old man, and when the old man can eat and drink, we should try to meet all the requirements of the old man. Of course, in addition to work, you should still take out more time to accompany the elderly at home, because for most of the elderly, having children by their side is actually the happiest.

At a glance, I knew that the old man was seriously ill, and my grandfather was like this, only drinking water and not eating anything else for 4 days, and his body had been the same, and he should be able to hold on for seven or eight days.

If you don't eat for seven days, you will die, and if you don't drink water for three days, you will die.

Add milk and coconut water.
