Fresh plain water is the best option
Boiled water is water in its natural state, boiled after multi-layer purification treatment, high temperature kills the microorganisms in the water, and the calcium and magnesium elements in the water are very beneficial to health.

Avoid drinking light salt water
Some older people believe that drinking light salt water is good for their health, so they choose to drink light salt water in the morning when they wake up. However, studies have shown that people sleep through the night without drinking water, while breathing, perspiration, and urinary are still underway, and these physiological activities consume a lot of water. Drinking plain water in the morning can quickly thin the blood and correct hypertonic dehydration at night. Conversely, drinking salt water can aggravate hyperosmolar dehydration, making the mouth more dry. In addition, early morning is the peak period for the body's blood pressure to rise, and drinking salt water may further increase blood pressure.
Avoid drinks such as fruit juices, cola, etc

The citric acid in carbonated drinks accelerates the excretion of calcium, resulting in a decrease in the amount of calcium in the blood, which may lead to calcium deficiency due to long-term consumption. Some other beverages have a diuretic effect, but drinking them early in the morning can increase the body's need for water, resulting in a lack of water in the body.

It is best to drink 20-25 warm water
Studies have found that boiled boiled water cooled to 20-25 has specific biological activity, easily penetrates cell membranes, promotes metabolism, and enhances immune function. People who are Xi to drinking warm and cool boiled water have higher deoxygenase activity in the body, good metabolic status, reduced accumulation of lactic acid in muscle tissue, and are not easy to feel fatigue. Pay attention to cover when drying boiling water, because boiling water will lose its activity if exposed to air for too long.
A healthy person needs to drink at least 7-8 glasses of water a day (about 2.).5 liters), when the amount of exercise is heavy or the weather is hot, the amount of water should be increased accordingly. Waking up in the morning is a critical time for the body to rehydrate the day, and it is best to have a first glass of water of 300 ml.
