Drink water healthily, remember five wants and five don't

People's health is inseparable from water, but the method of drinking water should be appropriate, otherwise it will damage health.

1、 Drink boiled water, not raw water.

Boiled and boiled water for 3 minutes is not only sterile, but also can maintain the necessary nutrients for human body. At present, it is considered that boiled water is the best drinking water. The harm of drinking raw water is well known. Raw water contains pathogenic bacteria. In addition, chlorine in water interacts with residual organic matter in uncooked water to produce a carcinogen called trihydroxy group. According to the survey, people who often drink raw water are more likely to suffer from bladder cancer and rectal cancer.

2、 Drink fresh boiled water instead of 'old water'.

Fresh boiled water is not only aseptic, but also contains a variety of minerals needed by the body. Do not drink the water that has been stored for too long, the boiled water that has been reboiled overnight in the automatic water heater, the residual boiling water that has been repeatedly boiled for many times, the water stored in the thermos bottle that is not the same day and the water from the steamer that has steamed the food. Some of these substances, such as nitrite, may be harmful to human body. It is not uncommon to cause nitrite poisoning.

3、 Drink hot water with salt, not ice water.

After exercise or after a lot of sweating in hot weather, drinking light boiled water without salt can not be retained in the tissue cells, but more easily discharged with sweat or urine. As a result, the more thirsty you drink, the more likely you are to suffer from hyponatremia such as palpitation and weakness. At this time, you should drink more salt water to make up for the lost water and salt. After hot water into the body, it will quickly penetrate into the cells, so that the body is sweating and lack of water in time to get water supplement.

4、 Drink moderate amount of water, do not drink too much.

The amount of drinking water a person can drink every day depends on the climate, temperature, physical condition and working conditions. In general, a person has to discharge about 2.5 kg of water from the body every day, most of which need to be supplemented by drinking water and food. Therefore, it is necessary to drink more than 2000 ml of water every day to keep the balance of water. However, excessive drinking will increase the burden of the center of gravity, lung and gastrointestinal tract, causing dyspepsia, gastroptosis, and even heart and lung failure.

5、 Do not drink only when you are thirsty.

In the morning, we should drink a small amount of water for many times, which can not only supplement the water consumption at night, but also promote the secretion of digestive juice, increase appetite, and stimulate gastrointestinal peristalsis, which is conducive to regular defecation and lower blood pressure. Thirst is a signal from the brain center asking for water. Thirsty shows that the body water has been out of balance, and then replenish water, in the past, twice the work.
