1, what to drink?
Fresh boiled water is the best choice. Boiling water is boiled from natural water after multi-layer purification. Microorganisms in water have been killed by high temperature, and calcium and magnesium in boiling water are very beneficial to health. Studies have shown that hard water containing elements such as calcium and magnesium can prevent cardiovascular diseases.
It is best not to drink juice, cola, soda, coffee, milk and other drinks in the first glass of water in the morning. 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, thus causing water shortage in the body.
2. What is the most suitable temperature?
Some people like to drink ice water in the refrigerator after getting up in the morning, which is the most refreshing. In fact, it is not appropriate to drink such water in the morning, because the gastrointestinal tract has been emptied at this time, and too cold or too hot water will stimulate the gastrointestinal tract and cause gastrointestinal discomfort.
Drink water in the morning, it is best to drink the same boiling water as room temperature, and drink 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. People who are used to drinking warm and cold boiled water have higher deoxyenzyme activity in their bodies, good metabolism, less accumulation of lactic acid in muscle tissues and are 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 do you 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. At this time, it is best to drink 300 ml of water.
4. How to drink?
Drinking water in the morning must be on an empty stomach, that is, drinking water before breakfast, otherwise it will not achieve the effect of promoting blood circulation and gastric lavage. It is best to drink water in small sips, because drinking water too fast is very harmful to the body, which may cause blood pressure reduction and brain edema, leading to headache, nausea and vomiting.
