Avoid ten misunderstandings. Drink water to moisturize the skin.

Online source of family doctor: Sohu Health Channel 2011/8/18 5: 24: 37.

Pay attention to ten misunderstandings:

Myth 1: For beauty and health, the more water you drink, the better.

Water is very important for beauty, and full and smooth skin can not be separated from the moisture of boiling water. But for women, the more you drink, the better. Eight glasses of water a day is enough to meet the needs of the body. In addition to these eight glasses of water, we can also supplement a lot of water through food. There is really no need to force yourself to drink plenty of water, otherwise the extremes meet, which will increase the burden on the kidneys.

Myth 2: After getting up in the morning, drink a cup of light salt water to promote detoxification.

People don't drink water all night during sleep, but breathing, sweating and urination are still going on. These physiological activities consume a lot of water, but drinking salt water will aggravate hypertonic dehydration and make people more thirsty. Moreover, the blood viscosity of human body is the highest in the morning. Drinking salt water will raise blood pressure, especially for people with poor heart function and high blood pressure. Experts suggest that light salt water is more suitable for drinking after exercise or sweating to supplement the water and sodium lost by the body.

Myth 4: Soup is equivalent to water, and drinking soup is smarter than drinking water.

Besides water, soup is rich in salt and fat. Therefore, although you can replenish water in the form of soup, you will also eat more salt and fat, which will gradually eat away at your good figure, so drinking soup is not a good way to replace drinking water. From the perspective of losing weight, it is wise to drink porridge.

Myth 5: Women can keep beautiful by drinking more water, while men can drink less water.

From a health point of view, men need to drink more water. American scholars have found that drinking plenty of water can prevent urinary calculi and bladder cancer, and men account for about 3/4 of the patients with these two diseases. All in all, men who drink more than 4 glasses of water a day have a 32% lower risk of cancer than men who drink 1 cup or less. In addition, even if men and women drink the same amount of water, men are prone to dehydration, because they are active, and love sweating is more prone to dehydration than women.

Myth 6: "Drinking water also makes you fat", and drinking more water will lead to obesity.

It must be because other diets consume more calories than they do, but people usually forget or don't want to remember. Scientific research shows that drinking water several times before meals is 1 hour, and the amount of water consumed each time is small. The ideal way is 250 ml at a time, once every ten minutes. The water drunk on an empty stomach only stays in the stomach for a few minutes, quickly enters the small intestine, is absorbed into the blood, and can be replenished to the cells and tissues of the whole body in about 1 hour, which can help people control their food intake, prevent overeating and help lose weight.

Myth 7: Thirst is the lack of water in the body. If you are not thirsty, you don't need to drink water.

Unlike eating, people's desire to drink water is far less intense. When you feel thirsty, you are on the verge of dehydration step by step, and your body has lost a lot of water. Even if you replenish water at this time, your body is still prone to symptoms such as inattention, irritability, fatigue and even headache. Therefore, when drinking water, we should pay attention to taking preventive measures. You can judge whether to adjust the water consumption according to the color of your urine. Generally speaking, if the urine color is dark yellow, it means that the body is short of water and needs more water.

Myth 8: Bottled water tastes good, clean and hygienic, and it is definitely better than tap water.

If some health details are ignored, bottled water is not necessarily better than tap water. For example, the boiled water in the water dispenser is easy to deposit minerals due to repeated boiling and heat preservation, which is not good for human health. In addition, because ordinary drinking fountains do not have any sterilization and bacteriostatic function, bacteria and microorganisms can easily enter the drinking fountains through water-gas exchange, and after a certain period of accumulation, it will cause secondary pollution to drinking water, not to mention whether the buckets that are reused many times are safe.

Myth 9: Purified water removes impurities, and long-term drinking is good for health.

After distillation and filtration, natural water will remove impurities, bacteria and other harmful substances, but at the same time it will also take away trace elements useful to the human body. Drinking pure water for a long time will also increase the loss of calcium. In addition, because human body fluids are slightly alkaline, and purified water is weakly acidic, if you drink weakly acidic water for a long time, the environment in your body will be destroyed, thus reducing immunity and accelerating aging. Experts remind that pure water is suitable as a supplement to drinking water, but it is not suitable for long-term drinking.

Myth 10: Drinking more coffee, tea and drinks can also replenish water.

Both coffee and tea have diuretic effects. Excessive drinking will lead to excessive urination and water loss. In other words, after drinking a cup of coffee, you must make up two glasses of water to make up the water consumed by drinking coffee; Most carbonated drinks such as soda and cola contain citric acid, which will accelerate the excretion of calcium in metabolism and reduce the content of calcium in blood. Long-term drinking will lead to calcium deficiency in the body and induce osteoporosis.

How to drink water correctly?

Drink more low-temperature boiled water.

Low temperature boiling water is to cool boiling water to about 25℃. The biological activity of this kind of water is 4-5 times higher than that of natural water, and these properties are very close to the cell fluid of human body, so it is easy to penetrate into cells and be absorbed by human body. Drinking warm water regularly can improve human immunity, relieve fatigue, keep skin moist and make people radiant.

Take a sip and enjoy yourself.

Drinking water too fast and too hard is bound to swallow a lot of air together, which is easy to cause hiccups or bloating, especially for people with weak stomach. Drink water slowly in a good mood. I also suggest that you'd better keep water beside you, so that you can remember to drink it often.

Reject aging water

If water is not in motion all the time, but in a static state, it becomes commonly known as "stagnant water", that is, aged water. Nowadays, many bottled or bottled purified water is often stored for a long time from the factory to drinking, which also affects the water quality. Barreled or bottled drinking water, after opening and standing for more than 3 days, will become old water and is not suitable for drinking.

Choose healthy and high-quality water

Good water quality conditions should not contain pesticides, heavy metals, bacteria and other harmful substances; Inorganic components such as calcium should be dissolved evenly, and weakly alkaline water with PH value of 8-9 is suitable. The water should be cold, preferably 20℃-25℃ below the body temperature; Preferably rich in hydrogen ions.

Better use a cup.

This kind of glass contains no organic chemicals in the firing process. When people drink water or other drinks from glasses, they don't have to worry about chemicals being drunk into their stomachs. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall. It should be said that the first choice for wine glasses should be glasses.

Drink some fancy water properly.

For women, the unchanging boiled water is really tasteless. In order to adjust, you can also add scented tea, green tea, or sugar-free juice rich in vitamins to the water, but you must drink white water in the morning and evening, and it is not advisable to replace water with tea and drinks.
