Water is the source of life, and all life activities of the human body are inseparable from water. For the human body, water not only transports various nutrients in the body, but also directly participates in the metabolism of the human body. Therefore, ensuring sufficient water intake is crucial for the normal operation of human physiological functions. How much water should we drink every day? Generally speaking, the amount of water a person drinks every day should at least be balanced with the water consumption in the body. The amount of urine excreted by the human body in a day is about 1500 ml, plus the water evaporated from feces, breathing or skin, the total water consumption is about 2500 ml, and the human body can neutralize it from food every day. The amount of water added to the body's metabolism is only about 1000 ml, so a normal person needs to drink at least 1500 ml of water every day, which is about 8 cups. Drinking water has the following benefits: 1. Promotes metabolism, digestion and absorption; 2. Transports nutrients; 3. Excretes waste; 4. Facilitates defecation; 5. Antipyretic and cooling; 6. Lubricates joints, muscles and organs; 7. Keeps skin moist; 8. Sedative; 9. Increased vitality; 10. Diuretic. Drinking too much water for normal people will not have much impact on health, but it may cause increased urination and cause inconvenience in life. However, for some special groups, special attention must be paid to the amount of water they drink. For example, patients with edema, heart failure, and renal failure should not drink too much water, because drinking too much water will increase the burden on the heart and kidneys, which can easily lead to As the condition worsens, these people should receive specific advice from their doctor on how much water they should drink depending on their condition. For patients with diseases such as heat stroke, cystitis, constipation and dry skin, drinking more water can alleviate the condition. In addition, people should drink more water when they have a cold or fever, because rising body temperature will cause water loss. Drinking more water can lower the body temperature and prevent excessive water loss. Tips: Drinking water schedule 1. After getting up: Drinking an appropriate amount of water after getting up in the morning can compensate for the consumption of water at night, and also has a certain effect on preventing the formation of high blood pressure, cerebral hemorrhage, and cerebral thrombosis. ２． Drinking water on an empty stomach about 1 hour before meals can replenish water to tissue cells throughout the body, supply the body's need for water, and ensure the secretion of necessary and sufficient digestive juices to promote appetite and help digestion and absorption. At the same time, it does not affect the physiological water content in tissue cells, and can also avoid drinking water thirsty before going to bed, which may cause swollen eyes after waking up at night or the next day. 3. Drinking water during work breaks in the morning and afternoon can replenish the water excreted through work sweat and urine, and the waste accumulated in the body will be smoothly discharged. 4. When you get off work, drink a glass of water before leaving the office to increase your feeling of satiety. 5． Drinking water 2 to 3 hours before going to bed can dilute the blood and accelerate blood circulation. Of course, the choice of time also varies from person to person. As long as you master the general principle of replenishing water in time, don't let the body be dehydrated. Principles of correct drinking water Many people often only think of drinking water when they are thirsty, and they often swallow in large gulps. This approach is also wrong. Drinking water too quickly will swallow a lot of air, which can easily cause hiccups or abdominal distension. Therefore, it is best to hold the water in your mouth first, and then drink it slowly. Especially for people with weak stomachs, drinking water is more important. Drink slowly, one sip at a time. Do not drink water when you are thirsty. Drink an appropriate amount of water between meals, preferably a glass every hour. People can also judge whether they need to drink water based on the color of their urine. Generally speaking, human urine is light yellow. If the color is too light, it may be due to drinking too much water. If the color is darker, it indicates the need for water. Add some more water. Drinking less before going to bed and drinking more after going to bed is also the principle of correct drinking water, because drinking too much water before going to bed will cause swollen eyelids, frequent trips to the toilet in the middle of the night, and poor sleep quality. After a night's sleep, the human body loses about 450 ml of water, which needs to be replenished in time in the morning. Therefore, drinking a glass of water on an empty stomach after getting up in the morning is beneficial to blood circulation, and can also promote a clear brain, making the day's thinking clear and agile. Drink more boiled water, not raw water. Boiling water for 3 minutes can evaporate the chlorine and some harmful substances in the water, while maintaining the necessary nutrients for the human body. Drinking raw water has many harmful effects, because the chlorine in tap water can interact with residual organic matter in unboiled water, leading to an increased chance of bladder cancer and rectal cancer. Drink fresh boiled water and do not drink water that has been left for too long. Fresh boiled water is not only sterile, but also contains more than a dozen minerals needed by the human body. However, if the time is too long or if you drink water that has been reboiled overnight in an automatic water heater, it will not only lose various minerals, but may also contain some harmful substances, such as nitrite, etc. The resulting nitrite poisoning is not uncommon. Plain water is the best drink. Plain water contains no calories and can be directly absorbed and utilized by the body without digestion. It is generally recommended to drink warm water below 30 degrees Celsius. This will not overly stimulate the peristalsis of the gastrointestinal tract and cause vasoconstriction. Improper drinking of water can lead to "poisoning". "Water intoxication" refers to excessive drinking of water for a long time or the body must excrete excess water through urine and sweat in a short period of time. However, as the water is excreted, the body's electrolytes, mainly sodium, It will be diluted, the salt content in the blood will become less and less, and the water absorption capacity will decrease accordingly. Some water will be quickly absorbed into the tissue cells, causing cell edema. Symptoms such as dizziness, weakness, and rapid heartbeat may initially appear. In severe cases, convulsions, disturbance of consciousness, and coma may even occur.
Therefore, it is very dangerous for some girls to try to drink a lot of water to lose weight. Replenishing water varies from person to person. In addition to thirst, healthy people use the color of their urine to pay attention to when they should replenish more water: the normal color of urine should be light yellow. If the color is too dark, more water must be added; if the color is very light, Maybe you drank too much water. Drinking more water can stimulate intestinal peristalsis and soften stools. Therefore, people with constipation should pay special attention to getting enough water. Drinking more water when you have a cold or fever can help the body dissipate heat and help the patient recover. People who exercise a lot also need to increase their water intake. Patients with cystitis often control drinking water due to poor urination. In fact, this is an unwise approach. Such patients drink more water than usual, which increases urine output and increases flushing and circulation.
