According to the formula of daily drinking water provided by the International Institute of Medicine in Los Angeles, California, USA (for reference only), if you don't exercise much, you should drink 15 ml of water every half kilogram (that is, a person weighing 80 kg should drink 2400 ml or 2.4 liters of water every day); If you are an athlete, you should drink 20 ml of water every half kilogram (a person weighing 80 kg should drink 3,200 ml or 3.2 liters of water every day). Of course, it also depends on the amount of daily activities of individuals. Life is inseparable from water, and water and air are indispensable in human metabolism. Humans may survive for weeks without food; You may die if you don't drink water for three days, which shows the importance of water to human beings. What water do you drink? How to drink water? How much water do you drink? These seemingly insignificant problems are the key to a healthy life. Drinking water is actually a kind of learning. All cells in the human body need water, which is the main component of the human body; Blood circulation, digestive system or other chemical actions all need water to complete. One of the messages that human body is short of water is thirst. Normal people's daily drinking water is about 1.5 liters (if calculated by how many cups, it is equivalent to about eight cups of 200 ml of water). But it also depends on the physiological conditions of personal activities. Water is both a scavenger and the patron saint of the human body. How much and how do we absorb to be healthy? At least 900 ml of water passes through the kidneys, lungs, intestines, digestion, secretion and skin loss every day, so it is absolutely necessary to drink more water in order to make water play a medical role in the body. Although water has so many benefits to human body, not everyone is suitable for drinking plenty of water. Drinking more water for normal people will not have much impact on the body, but it may lead to increased urination and inconvenient life. However, people with heart disease, kidney and liver problems are not suitable to take general measures to drink more water, because drinking too much water will aggravate the condition. Such people had better follow the doctor's advice on how to drink water and how much water to drink. In addition to thirst, ordinary people can also pay attention to when to replenish water through the color of urine: the normal color of urine should be light yellow, and if the color is too dark, it must be replenished more; If the color is very light, it may be too much water. Insufficient water intake is prone to urinary tract infections, stones, constipation and other problems. Drinking more water can stimulate intestinal peristalsis and soften stools; Therefore, people with constipation should pay special attention to adequate water intake. Drink plenty of water when you have a cold or fever, because rising body temperature will cause water loss. Drinking enough water can promote body heat dissipation and help patients recover. In addition, people who exercise a lot also need to drink more water. A small number of people still have a wrong understanding of drinking water. For a simple example, some patients with cystitis often control the amount of water they drink because of difficulty in urination. In fact, this is very unwise. On the contrary, this kind of patients drink more water than usual, which increases the amount of urine, thus increasing the role of washing and circulation. Water has diuretic effect, which can make ureter and bladder unobstructed and prevent stones and bacterial infection. It is not necessary to use tea, soup, fruit juice or other drinks instead of boiled water, as long as the amount is appropriate, but boiled water is still the most ideal. Because these drinks contain more or less sugar and other additives, too much will still have an impact on health. Parents must pay more attention to their children's water intake and don't let them drink too much processed drinks such as soda. It is better to use freshly squeezed juice instead. As for whether you need to drink all kinds of good quality water sold in the market, it depends on your personal preference. In fact, the most important thing to drink water is the cleanliness of the water. As long as it is clean and hygienic, it will meet the standard. Some people call processed drinks "junk drinks", of course, it is useless to drink too much, but it is better to drink less. Therefore, pure boiled water is better for the body, and some processed drinks will cause a burden on the body. Many people think that as long as they drink liquid drinks, even if they replenish water, they don't know that there are many kinds of drinks. Drinking drinks with too much sugar and salt will not only help the body, but also have a negative impact. Is it better to drink cold water or hot water? Generally speaking, it is recommended to use warm water below 30 degrees, which is more in line with the physiological function of the gastrointestinal tract and will not excessively stimulate the gastrointestinal tract to cause vasoconstriction or stimulate peristalsis. Traditional ideas often say not to drink too cold water, but from the perspective of modern medicine, as long as the water source is clean, there is no need to worry about the negative impact on health. Of course, if you are sick or have other health problems, that is another matter. Drink water according to your body's feelings. Although there is no prescribed way to drink water, drinking plenty of water is not an ideal way to replenish water. Generally speaking, it doesn't say how to drink water correctly, but you shouldn't drink too fast. This will inevitably swallow a lot of air, which is easy to cause hiccups or bloating. If you have a bad stomach, drink water slowly. Therefore, drinking water is best adjusted according to your daily routine, lifestyle and physical condition. According to medical research, everyone consumes at least 1.5 liters of water every day. Some foods we eat every day already contain a lot of water, such as soup, vegetables and fruits we drink every day. Therefore, it is best to decide how much water to drink according to everyone's activity, so as to avoid taking too much or too little; Drinking too much water will increase the burden on the heart and kidneys. In short, how much water each person needs to drink varies according to the activity, environment and even the weather. Physiologically, the human body has a system to maintain self-balance; So even if the human body needs different amounts of water in different situations, the body will send out certain information (such as thirst) to let you know. Therefore, drinking water requires drinking more water; Patients who should not drink more water should be supplemented appropriately according to the doctor's advice. In fact, ordinary people don't need to worry too much about how much water to drink, just need to feel the instructions from the body. Of course, it does not include the above organ dysfunction. The most important way to drink water is "water can carry a boat and also overturn it". Drinking too much or too little water is unhealthy. Attention must be paid to the following points in drinking water: ※ The quality of drinking water must be filtered clean water. Although all kinds of drinks also contain most water, there are various other chemical additives that are harmful to health. The best time to drink water is to drink water in balance during the day and at night, and don't drink too much water in an hour. The time of drinking water every day is: ★ After getting up in the morning, I may get a little dehydrated because I haven't replenished water for a while. ※. It's best to drink a glass of water first to get your body working again.
