Why do people drink plain water, and what are the pros and cons of drinking only plain water?

Fresh plain water is the best option. Boiled water is boiled after multi-layer purification of water in its natural state, and the microorganisms in the water have been killed in high temperatures, while the calcium and magnesium elements in boiled water are very beneficial to health. Studies have shown that hard water containing calcium, magnesium and other elements has the effect of preventing cardiovascular diseases.

Many people think that drinking light salt water is good for their health, so they drink light salt water in the morning, but this understanding is wrong. Studies have shown that people who do not drink a drop of water during their sleep throughout the night, but breathing, sweating, and urinary are still going on, and these physiological activities consume and lose a lot of water. Drinking some plain water in the morning can quickly thin the blood and correct the hypertonic dehydration at night.

On the other hand, drinking salt water can aggravate hyperosmolar dehydration and make people more dry. What's more, the morning is the first peak of the body's blood pressure increase, and drinking salt water will make the blood pressure higher. It is best not to drink juice, cola, soft drinks, coffee, milk and other beverages in the first glass of water in the morning.

Most carbonated drinks such as soda and cola contain citric acid, which can accelerate the excretion of calcium in metabolism and reduce the amount of calcium in the blood, which can lead to calcium deficiency after long-term consumption. Other drinks have a diuretic effect, and drinking them in the morning not only cannot effectively replenish the lack of water in the body, but also increases the body's demand for water, which in turn causes a lack of water in the body.

Because, two-thirds of the human body is full of water, and there are many basic components in white water.

Drinking 8 glasses of water a day is good!

Water is the best drink and there is nothing wrong with it. The usual various drinks contain a lot of sugar and are prone to tooth erosion. Tea and coffee are not suitable for everyone, and people who do not sleep well cannot drink it. I also basically only drink plain water.

To put it simply, after a few hours of fasting, a person begins to break down proteins and fats to produce glucose after a few hours of fasting. At 24 hours, glycogen is depleted and energy** is completely converted to burning protein and fat.

Since the human body has a mechanism to protect proteins, protein breakdown is inhibited. After 3 days of fasting, energy** shifts to the ketones produced by lipolysis to dominate. After 1 week, energy expenditure is almost entirely dependent on ketone bodies.

Therefore, with continuous fasting, if nothing else, a person's fat storage determines how long they can survive after a complete fast.

According to studies, a well-nourished, 70-kilogram person has a total of about 161,000 kcal of total energy reserves stored in the form of fat. If the energy consumption is 1600 kcal and 6000 kcal per 24 hours according to the different energy consumption levels of the human body, the total energy reserve can meet the needs of about 30 100 days, that is, 1 3 months.
