We all can't do without water. Water is the source of life. Drinking more water can replenish water, but drinking water is also exquisite. Drinking more water is better than drinking water. Do you really know how to drink water?
Taking stock of bad habits of drinking water that may harm your health
1. Love bottled water.
It's easy to carry and drink. In China, the consumption of bottled water is increasing by 30% every year. Polyester bottles used in bottled water often contain substances that may lead to chronic poisoning of human body, especially when the bottles are in high temperature environment or are not drunk in time after opening, harmful substances will infiltrate into the water and endanger health. Therefore, bottled water must not be heated or exposed to the sun. 'many people like to put a box of water in the car, which is not right. Especially in summer, the temperature of the boot is very high, which is easy to let harmful substances into the water. The best way is to buy a good quality water bottle and bring your own water, safe and environmentally friendly.
2. Drink tap water as soon as it's boiled.
It's a good habit to drink boiled water, but you know what? Water can't be drunk as soon as it's boiled. Because our tap water has been chlorinated and disinfected, in which chlorine combines with the residual organic matter in the water to produce halogenated hydrocarbon, chloroform and other carcinogenic compounds. When boiling water, it is advisable to take three steps: first, connect the tap water and place it for a while before burning; when the water is about to open, open the lid of the pot; finally, wait 3 minutes after the water is opened and then turn off the fire, so as to reduce the chlorine content in the water to the safe drinking standard, which is the real "boiled water".
3. The water fountain never washes.
Bottled water and water fountains are very common in home, office and public places. Have you ever thought that the water fountains you use have never been 'bathed' since they were put there. Drinking fountains seem to make people drink good quality water, but in fact, secondary pollution is very serious. When opening the faucet of the water dispenser, the sound of "guru" is heard, and a string of bubbles come out of the barrel. This is that there is air entering, and dust and microorganism will be brought in. According to the data, the cold and hot water tanks in the bottled water dispenser will generate a large number of bacteria, such as Escherichia coli, Staphylococcus, etc. if they are not washed for three months. Therefore, it is better to clean once a month and once every two weeks in summer. Because of the frequent use of office water fountains, they have to be cleaned more frequently.
4. No thirst, no water.
According to the data, seven adults drink water when they feel thirsty. But when you feel thirsty, your body has lost at least 1% water. The purpose of drinking water is not to quench thirst, but to let it participate in metabolism and be absorbed by human body. Water shortage for a long time will increase blood viscosity and induce cardiovascular and cerebrovascular diseases. At the same time, the less attention is paid to drinking water, the lower the desire to drink water will be, and people will become more and more 'dry'. So, whether you are thirsty or not, you should replenish water in time. Take a bottle of water with you when you go out and have a drink at any time; put more water glasses in the office or at home and drink them whenever you have a chance.
5. Drink a thousand boiled water.
Now there are more and more families using electric kettle. Many people can't drink all the boiled water at one time, and then boil it again and again later. It's better not to drink this kind of boiled water. Boil the water as soon as possible, and don't heat it repeatedly. Many people are worried about whether the water in the water dispenser is thousand boiling water. Due to the limitation of materials, the maximum temperature of water in the water dispenser is generally about 90 ℃, which can not reach the boiling state, not thousand boiling water. But the best drinking time of bottled water is 1-15 days after leaving the factory. Once more than 15 days, there are too many bacteria in the water, it is not suitable to drink again.
6. Do not drink water or drink instead of water according to the constitution.
Boiled water doesn't taste, so drink it. Many people can't leave their hands on cola and fruit flavored drinks every day. Replacing water with drinks is like spending money to buy diseases. Drinking drinks not only can't replenish water for the body, but also can reduce appetite, affect digestion and absorption. If we must drink water with taste, we should also improve it according to our own constitution. For example, people with constipation can drink honey water or fruit and vegetable juice, which can promote intestinal peristalsis; people with cold stomach should drink less cold green tea, herbal tea, juice, and more warm black tea, ginger sugar water.
7. Less than six glasses of water a day.
Working people often neglect to drink water due to working relationship. In the long run, bladder and kidney will be damaged. Adults who live in mild climate and have light physical activity are advised to drink at least 1200 ml of water every day, about 6 cups. If there is a large amount of activity and sweating, the drinking water should be increased accordingly and the water should be replenished in time. Some people will ask, before always said that every day to drink water no less than 2000 ml, that is, 8 cups of water, why now only 1200 ML?
In fact, 2000 ml refers to the total amount of water that people need in a day. Fruits and vegetables contain a lot of water, even in staple food and meat. A large part of the water that people need comes from food. Six cups is the minimum amount. Some people need to drink more. For example, people who are fidgety can drink more water to ease their mood, fat people can drink more water to maintain their weight, and they should supplement water in time after exercise and bathing.
Benefits of drinking water
1. Excretion waste: the residual waste after the nutrition digestion and absorption of food should be discharged from the body through sweating, breathing and excretion. These different excretion methods can only be realized with the help of water.
2. Help digestion: when we eat the food in our mouth, after the teeth are chewed and saliva is moistened, we carry out the digestion process from the esophagus to the gastrointestinal tract, and complete the digestion and absorption, all of which need the participation of water to accelerate the dissolution of nutrients in body fluids.
3. 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 reduction of evaporation of the shrinking pores; when the ambient temperature is higher than the body temperature, the water will be discharged through the expanded capillary breathing holes to reduce the body temperature. The body ensures the survival function through the flow of water.
4. Lubricating joints: human joints need lubricating fluid to avoid damaging friction between bones, and water is the main source of joint lubricating fluid.
5. Balance blood: water can improve the circulation of blood and tissue fluid, and help to balance the viscosity and pH of blood.
6. Maintain cells: water can promote cell metabolism, maintain normal cell shape, keep skin moist and elastic.
