Water accounts for 60% of the human body's weight (40% intracellular fluid, 15% interstitial fluid, 4% plasma, and 1% lymph and cerebrospinal fluid), and all the body's functional activities are inseparable from water. The water in the body is called body fluid, which is divided into two major parts: intracellular fluid and extracellular fluid. They can regulate each other to ensure the normal and healthy functioning of the body.
Drinking water in the morning has many benefits. When people sleep at night, they lose a large amount of water through urine, respiration, and skin sweat. After waking up in the morning, they are in a state of physiological dehydration. Drinking a glass of water early in the morning can not only replenish the body's need for water, but also flush the gastrointestinal tract, beautify the skin, and refresh the brain. The water drunk after waking up will be quickly absorbed by the intestinal mucosa into the bloodstream, which can effectively increase blood volume, dilute the blood, reduce blood viscosity, promote blood circulation, and help the brain quickly return to a clear state. Therefore, drinking water in the morning is very beneficial, especially for middle-aged and elderly people who should pay more attention to drinking water for health in the morning.
What kind of water to drink? Medical experts believe that drinking plain boiled water in the morning is the best choice. Because microorganisms in plain boiled water have been killed at high temperatures, and the calcium and magnesium elements in it are beneficial to the body. But do not drink water that has been left for too long. Because if boiled water is left for too long, or if you drink water from an automatic water heater that has been reheated overnight, it not only lacks minerals but may also contain some harmful substances. Some people, in order to make the water taste better, drink juice, cola, soda, coffee, milk, and other beverages as their first glass of water in the morning, which can be harmful to the human body. Because carbonated drinks like soda and cola contain citric acid, which accelerates the excretion of calcium during metabolism, and long-term consumption can lead to calcium deficiency. Some beverages also have a diuretic effect, which increases the body's demand for water,反而 causing dehydration in the body.
How much water to drink in the morning A healthy adult should drink at least 7-8 glasses of water (about 2.5 liters) every day. The morning after waking up is a critical time for the body to replenish water. At this time, drinking 1 glass (about 300 ml) of water is best.[China Food]
What temperature of water to drink On cold days, you can drink warm water to minimize adverse stimulation to the gastrointestinal tract. Research has found that plain boiled water that has been boiled and then cooled to 20°C to 25°C has special biological activity, which can easily pass through the cell membrane, promote metabolism, and enhance the body's immune function. In the summer, you can drink cool boiled water. However, when you cool the boiled water the night before, be sure to cover it, because boiled water exposed to the air for too long will be contaminated and lose its biological activity.
How to drink Morning drinking must be done on an empty stomach, that is, drink water 15-30 minutes before eating breakfast, otherwise you will not receive the effects of flushing the gastrointestinal tract and promoting blood circulation. It is best to drink water in small sips, because drinking too fast and too forcefully is not good for the body and may cause a drop in blood pressure or cerebral edema, leading to discomforts such as headache, nausea, and vomiting.
