Drinking water has the following functions of healthy drinking water:

1. Detoxification: a glass of water in the morning. After a night of metabolism, the garbage in the body needs external force to be discharged, and water is the best "cleaner". At this time, the cell is like a dry sponge, which will catch the water it drinks and excrete it in about 40 minutes. This is an important detoxification process. Light salt water, honey water and boiled water are all suitable for drinking in the morning. Don't drink too cold or too hot water in the morning, the temperature is about 40 degrees Celsius.

2. fidgety: drink plenty of water. Endorphins produced by the brain are called "pleasure hormones", while adrenaline is usually called "pain hormones". When a person is upset, adrenaline will soar, but it can be excreted like other poisons. One way is to drink more water. If manual labor is assisted, adrenaline will be discharged with sweat, or with tears when crying.

3. Decompression: Drink a glass of water before making a decision. A study in university of east london, England, found that drinking a glass of water before an exam can improve students' cognitive ability and make them perform better in the exam. For office workers, drinking a glass of water before they are stressed or need to make a decision can help them clear their minds.

4. Not thirsty: You have to drink water, too. According to a survey, 1/3 adults drink less than 6 glasses of water every day. Office workers are busy at work and often don't take a sip of water for a long time. According to the American website "Water Health", when people feel thirsty, their bodies lose at least 1% water. Therefore, office workers should form good drinking and urination habits, drinking water once every 1 hour and urinating once every 2-3 hours.

5. Before going to bed: take two sips of water. When people sleep, due to the loss of water in the body, the water in the blood decreases and the blood viscosity becomes higher. Drinking some water properly before going to bed can reduce blood viscosity, thus reducing the risk of cerebral thrombosis. In addition, in dry autumn and winter, water can also moisten the respiratory tract and help people fall asleep better. But it should be noted that don't drink too much water before going to bed. Old people have the habit of getting up at night. If you can't sleep well because of drinking water, it's not worth the candle.

6. After bathing: Drink water slowly. Many people feel thirsty after taking a shower, and they will pick up the cup and drink it down. Because of the weak constitution of the elderly, their cardiac endurance is not as strong as that of young people. Especially after taking a hot bath, the blood vessels of the body are dilated by heat, the blood flow is increased, and the heartbeat is faster than usual. Be especially careful when drinking water. It is best to drink a cup of warm water slowly in a small mouth, otherwise it will easily increase the burden on the heart.

7. After exercise: Follow the heartbeat. Old people should not drink a lot of water at one time after exercise. Because the gastrointestinal blood vessels are contracting at this time, a recovery process is needed. If you drink plenty of water immediately, water will accumulate in the gastrointestinal tract, leading to bloating and affecting digestion. It's best to take a few minutes, wait for the heart to beat a little more smoothly, and then drink some warm water. Try to keep the speed gentle when drinking water, and the frequency of drinking water should be close to the heartbeat frequency, and then drink it intermittently for many times. In this way, the heart can regularly and smoothly absorb the water entering the body.

8. Cold: Drink plenty of water. Drink plenty of water or pure fruit juice when you have a cold, which is very helpful for the recovery of the disease, because it helps to wash away the mucus on the respiratory tract and make people breathe comfortably. In addition, if you have a fever, the human body will cool itself for self-protection function. At this time, there will be signs of accelerated metabolism such as sweating, shortness of breath, and increased evaporation of skin moisture, and a lot of water needs to be added. Drinking plenty of water can not only promote sweating and urination, but also help regulate body temperature and promote the rapid discharge of germs in the body.

9. Constipation: Drink plenty of water. There are two reasons for constipation: first, there is stool in the body and water shortage; Second, organs such as intestines have no excretory capacity. Take a big sip of water and swallow it quickly, so that the water can reach the intestine as soon as possible, stimulate intestinal peristalsis and promote defecation. Traditional Chinese medicine believes that one of the causes of constipation is the lack of body fluid, and drinking water in a big mouth can quickly replenish body fluid, thus stimulating intestinal peristalsis and promoting defecation. Chen Jian, chief nutritionist of the Nutrition Department of Shanghai Huadong Hospital, suggested that people with constipation should supplement some dietary fiber while supplementing water, so it is best to drink a cup of high-fiber vegetable juice every day.

10. Obesity: Drink a glass of water before and after meals. Many chemical reactions in the human body must be carried out in water. With enough water, we can ensure the normal operation of the body's metabolic mechanism. For obese people, you can drink a small glass of water about half an hour before meals to increase satiety; Half an hour after a meal, drink a small glass of water to strengthen the digestive function of the body and help to keep fit.

1 1. Vomiting: Drink some light salt water. Vomiting is a manifestation of self-protection after eating unclean food. In order to avoid dehydration symptoms caused by severe vomiting or diarrhea, you can drink light salt water to supplement your physical strength and relieve weakness.
