Physiological function of water

1. Help digestion: the food we eat in our mouth, chewed by our teeth and moistened by saliva, carries out the digestion process from esophagus to gastrointestinal tract, completes digestion and is absorbed. Water is involved in these links, Accelerate the dissolution of nutrients in body fluids.

2. Waste excretion: the residual waste after the digestion and absorption of food nutrition should be excreted through sweating, breathing and excretion. These different excretion methods can only be realized with the help of water.

3. Lubricating joints: human joints need lubricating fluid to avoid damaging friction between bones, and water is the main source of joint lubricating fluid.

4. Balance body temperature: when the ambient temperature is lower than the body temperature, in order to maintain the body temperature and ensure normal physiological activities, the water in the body will be retained in the body due to the reduced evaporation of the reduced pores; When the ambient temperature is higher than the body temperature, the water will be discharged from the body through the expanded capillary breathing hole to reduce the body temperature. The body ensures survival function through the dispersion of water.

5. Maintenance of cells: water can promote cell metabolism and maintain the normal morphology of cells; Keep skin moist and elastic.

reveal the little secret of drinking water

1. Detoxification: a glass of water in the morning. Many people know that drinking a glass of water in the morning is good for their health. After a night of metabolism, the garbage in the body needs the help of external forces to be discharged, and water is the best & quot; Cleaning agent & quot;. At this time, the cell is like a dry sponge, which will catch the water and discharge it in about 40 minutes. This is an important detoxification process. Light salt water, honey water and boiled water are very suitable for drinking in the morning. Don’t drink too cold or too hot water in the morning. The temperature should be about 40 ℃.

2. Irritability: drink plenty of water. The endorphins produced by the brain are called & quot; Happy hormone & quot;, Adrenaline is often called & quot; Pain hormone & quot;. When a person is in pain and irritability, adrenaline will soar, but it can be excreted like other poisons. One way is to drink more water. If you assist in physical labor, adrenaline will be discharged together with sweat, or cry, it will also be discharged with tears.

3. Decompression: drink a glass of water before making a decision. A study by the University of East London found that students drinking a glass of water before the exam can improve their 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 their mind become clear.

4. Not thirsty: you have to drink water. A survey shows that one-third of adults drink less than 6 cups of water a day. Office workers are busy with their work and often don’t care to drink for half a day. USA & quot; Water health & quot; The website points out that when people feel thirsty, their bodies have lost at least 1% of their water. Therefore, office workers should form good water drinking and urination habits, drink water every 1 hour and urinate every 2-3 hours.

5. Before going to bed: take a sip of water. When a person is asleep, due to the loss of water in the body, the water in the blood is reduced and the blood viscosity will become higher. Drinking water properly before going to bed can reduce blood viscosity and reduce the risk of cerebral thrombosis. In addition, in the dry autumn and winter season, water can also moisturize the respiratory tract and help people sleep better. However, it should be noted that the elderly should not drink too much water before going to bed. They have the habit of getting up at night. If they don’t sleep well due to drinking water, the gain is not worth the loss.

6. After bathing: drink water slowly. Many people feel thirsty after taking a bath and will pick up a cup and drink it all at once. Due to the weak physique of the elderly, the heart bearing capacity is not as strong as that of the young. Especially after taking a hot bath, when the body is heated, the blood vessels expand, the blood flow increases, and the heart beats faster than usual. You should be particularly careful when drinking water. It is best to drink a cup of warm water slowly, otherwise it is easy to increase the burden on the heart.

7. After exercise: drink with the heartbeat. After exercise, the elderly should not drink a lot of water at one time. Because the gastrointestinal blood vessels are in a state of contraction at this time, a recovery process is needed. If you drink a lot of water immediately, the water will accumulate in the gastrointestinal tract, which will lead to bloating and affect digestion. It’s best to wait a few minutes, wait until the heart beats a little steady, and then sip some warm water. When drinking water, try to keep the speed gentle. The frequency of drinking water should be close to the heartbeat frequency, and then drink it intermittently for many times. Only in this way can the heart absorb water smoothly and regularly.

8. Cold: drink more water. Drink more 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 feel comfortable breathing. In addition, if you have a fever, the human body needs to cool itself out of the reaction of self-protection function. At this time, there will be signs of accelerated metabolism such as sweating, shortness of breath, increased water evaporated from the skin, and a large amount of water needs to be added. Drinking plenty of water not only promotes sweating and urination, but also helps to regulate body temperature and promote the rapid discharge of bacteria in the body.

9. Constipation: drink plenty of water. There are two causes of constipation: first, there is stool and lack of water in the body; Second, the intestinal tract and other organs have no excretory power. Drink water and swallow faster, so that the water can reach the intestines as soon as possible, stimulate intestinal peristalsis and promote defecation. Traditional Chinese medicine believes that one of the reasons for constipation is the lack of body fluid. Drinking water can quickly supplement body fluid, so as to stimulate intestinal peristalsis and promote defecation. Chen Xiafei, chief nutritionist of the Nutrition Department of Shanghai East China Hospital, suggested that it is better for people with constipation to supplement some dietary fiber while replenishing 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 in & quot; Water & quot; Inside. With enough water, we can ensure the normal operation of the body’s metabolic mechanism. For obese people, they can drink a small glass of water about half an hour before meals to increase their sense of fullness; After half an hour, drink a small glass of water to strengthen the body’s digestive function and help keep fit.

11. Vomiting: drink some light saline. 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 some light saline to supplement your physical strength and alleviate your weakness.

when you get up in the morning, you should start the first glass of water, because you are asleep, but all organs of your body are still active. In addition, the body is sweating, and most of the water in your body has been metabolized.

in such a situation, the body is not only in a state of water shortage, but also the blood becomes viscous! At this time, drinking a glass of water can not only help the discharge of waste, but also dilute the blood.

in addition, the water consumption of human body during bathing is also very large, so thirst occurs after bathing. It is too late to supplement water after bathing.

the best way is to drink a glass of water before taking a bath. Especially friends who need to take a bath should drink a cup of warm water before entering the bath.

finally, pay attention to water replenishment after exercise, which is conducive to the discharge of body waste. However, it should be noted that drinking water after exercise should not be mainly cold water, but warm boiled water is more suitable for thirst quenching and water supplement after exercise.
