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.

If you get up in the morning and drink some boiled water, you can quickly dilute your blood and correct hyperosmotic dehydration at night.

Besides, morning is the first peak of human blood pressure rise, and drinking salt water will make blood pressure higher. The first glass of water in the morning is best not to drink juice, cola, soda, coffee, milk and other drinks. Most carbonated drinks such as soda and cola contain citric acid, which will accelerate the excretion of calcium in metabolism and reduce the content of calcium in blood. Long-term drinking will lead to calcium deficiency. Other drinks have diuretic effect. Drinking them in the morning can not only effectively replenish the water that the body lacks, but also increase the body's demand for water, which in turn causes water shortage in the body. 2.

Drinking water in the morning, it is best to drink the same boiling water as room temperature, and drinking warm boiling water when it is cold to minimize the irritation to the gastrointestinal tract. It is found that boiled water cooled to 20-25℃ has specific biological activity, which can easily penetrate cell membrane, promote metabolism and enhance human immune function. Anyone who is used to drinking warm and cold boiled water has higher activity of deoxyenzyme in the body, good metabolic state, less accumulation of lactic acid in muscle tissue, and is not easy to feel tired. Be sure to cover the boiled water when it is aired the night before, because the boiled water will lose its activity if it is exposed to the air for too long. 3. How much to drink? A healthy person should drink at least 7-8 glasses of water (about 2.5 liters) every day. When the exercise is heavy or the weather is hot, the water consumption will increase accordingly. Getting up in the morning is the key moment for the body to replenish water in the new day, and it is best to drink 300 ml of water at this time. How to drink?
