Deafening thunder began to sound, and then I told everyone that summer had arrived. Summer is the hottest season in the whole year, and people are particularly prone to water shortage because of sweating. It is very important to replenish water in summer. How to drink the first glass of water in the morning is very important. If you drink in the wrong way, it is easy to hurt your health.

Drink boiled water in the morning

Drinking a cup of boiled water in summer morning can replenish the moisture of cells, reduce the blood viscosity and facilitate urine excretion. Moreover, boiled water can quickly dilute blood, promote blood circulation and make people wake up faster.

The boiling water temperature is suitable.

Studies show that when the water temperature is about 25, water molecules have the best affinity with human cells, and the cells have the strongest water absorption capacity. It is best to drink a cup of warm water in the morning.

Proper amount of boiling water

The amount of the first glass of water in the morning should be appropriate, and 150-200ml is the appropriate drinking amount.

There is time for drinking water.

Drinking the first glass of water in the morning is best after brushing your teeth and before breakfast. Drinking water on an empty stomach in the morning can promote blood circulation and gastric lavage. But don't drink water before brushing your teeth, because it will bring bacteria from your mouth to your stomach.

You can't drink "four kinds of water" in summer morning.

1, a long-standing boiled water

After boiling water for a long time, there will inevitably be bacterial pollution, and the nitrogen-containing organic matter in the water will be decomposed into nitrite, which will affect the oxygen transport function of the blood.

2. Ice water

Drinking ice water in the morning can easily cause gastric mucosal vasoconstriction, stimulate gastrointestinal tract, accelerate gastrointestinal peristalsis, and even cause intestinal spasm, leading to abdominal pain, diarrhea and other symptoms.

3. Salt water

According to physiological research, people don't drink a drop of water during the whole night's sleep, but breathing, sweating and urination are all going on, consuming water in the body. The blood in the morning has been concentrated. Drinking a certain amount of boiled water can dilute blood and supplement hypertonic dehydration at night. If you drink salty boiled water, it will aggravate hypertonic dehydration and make people thirsty.

Step 4 drink

The first glass of water in the morning should not be fruit juice, cola, soda, coffee, milk and other drinks, because carbonated drinks such as soda and cola mostly contain citric acid, which will accelerate the excretion of calcium during metabolism and reduce the calcium content in the blood. Long-term drinking will lead to calcium deficiency in the body and can't replenish water in the body.
