Water and air play a very important role in human metabolism. People can live for several weeks without food. If they don't drink water, their physical activities can only last for a few days. The human body is 60% water. Brain tissue contains the most water, accounting for 75%. Therefore, if water is insufficient, it will affect the activity of the brain.

How much water do you drink?

Healthy adults consume more than two liters of water every day. Half of them form urine through the kidneys. Waste discharge from the body. The other half is excreted through the lungs, intestines and skin. Therefore, adults need to supplement six to eight glasses of drinking water every day. Sweating in hot summer or during exercise, they need to supplement a lot of drinking water.

You don't have to use tea, soup or fruit juice instead of water, but boiled water is still the most ideal. Drinking two cups of boiled water immediately after getting up in the morning can promote gastrointestinal digestion. Drinking water at a proper temperature is enough. Ice water should be avoided. Eating liquid food or drinking plenty of water during meals is not an ideal method of hydration, especially for people with weak gastrointestinal tract. It is best not to drink more water when eating.

Water is an unsung hero.

Adequate drinking water can stimulate intestinal peristalsis and soften stools, so people with constipation should pay special attention to absorb enough water.

Water also has diuretic effect, which makes ureter and bladder unobstructed and prevents stones and bacterial infection. People who don't like drinking water in daily life are more likely to suffer from urinary tract infections, such as urinary calculi and cystitis.

Adequate drinking water also helps patients recover. For example, when they have a high fever, enough water can promote the body to dissipate heat.

Fever in children and the elderly is sometimes caused by insufficient water in the body. Babies and young people keep vomiting. Dysentery patients need to be hydrated. When they are severely dehydrated, patients may have symptoms of dehydration, such as sunken eyes, listlessness, dry oral mucosa and lips, skin loss of elasticity, poor complexion, decreased urine output and dark yellow color. This situation is more common in children and the elderly. Hydrate quickly. Otherwise, it is very dangerous.

Don't be afraid to drink water

Some cystitis patients often control the amount of water they drink because they can't urinate normally. This is very unwise. On the contrary, such patients should drink more water than usual to increase urine volume and increase the effect of irrigation and circulation, especially for urinary tract infections treated with antibiotics.

Drinking water is very important, but it is also very important whether the water you drink is hygienic and reliable, because many diseases are spread through water. Fortunately, infectious diseases such as cholera, typhoid fever and dysentery have been reduced a lot now. Only when you travel abroad, you need to pay a little attention.

Therapeutic effect of water

Besides the importance of drinking water, water has many functions outside the body. For example, taking a hot bath can refresh the nerves and relieve physical and mental fatigue.

Water. Did you drink it right?

The importance of water

Water plays an extremely important role in the human body. Whether it's digestion, absorption, elimination of body wastes, chemical reactions in cells or thermoregulation, etc., all these chemical actions need water.

Water is used as a solvent for digestion and absorption. Nutrients produced by food decomposition are dissolved in water. After being absorbed by intestinal mucosa, it enters the blood, and the waste produced in the body is also dissolved in water. They are sent to the lungs, kidneys, intestines and skin through blood circulation and excreted. Chemical reactions in cells usually take place in water. If the water content in cells decreases, the metabolism of the body will decrease.

Because water has a large specific heat, it can absorb excess heat generated by the body and excrete it through sweating, thus maintaining body temperature. Every substance has a different specific heat. It is difficult to get cold or hot because of its large specific heat. Small specific heat, easy to be cold or hot. )

The human body is 60 -70% water, and muscles also contain 75% water. Even the water in the bones accounts for 20%. A person can go without food for several weeks, but he will die if he doesn't drink water for a few days. So do you know how important water is? ?

Environmental protection in the body-drink more water

Water is the basic component of human body, accounting for 70% of human body. Water is responsible for many important functions in the body, such as promoting the digestion and absorption of food, maintaining the normal circulation and excretion of the body, regulating body temperature, moistening tissue surfaces, reducing friction between organs and helping to maintain the balance of electrolytes in the body. Once the human body is short of water, its life is immediately threatened. The main sources of water are boiled water, various drinks, soup, vegetables and fruits. Soup, vegetables and fruits are all.

This is a new product launched this year. Manufacturers emphasize that amino acid drinks contain branched-chain amino acids (BCAA), which can delay fatigue, improve muscle endurance time, increase muscle tissue synthesis and promote fat decomposition. In addition, it can also reduce visceral fat accumulation and improve body composition. However, the active ingredients of this popular drink are not high, and the amount of amino acids contained is even very small. Total amount is less than 1.

In fact, a balanced diet and proper intake of protein every day can meet the needs of the body! Amino acid supplements are unnecessary. It just took in some extra calories.

How much water should you drink?

For human beings, the importance of water is second only to oxygen, and the amount of water needed by each person every day is also different due to personal activities and weather. The amount of urine that people excrete every day is about 1, 000- 1, 500 c.c, plus sweat, water vapor generated when exhaling, water evaporated from skin and feces, etc. , add up to about 2500 c.c

The benefits of good water are endless. But do you know how to drink water?

1. Drink slowly when drinking water. Don't drink it all at once Water intake should be evenly distributed throughout the day. Don't drink all the water at once.

Don't wait until you are thirsty to drink water. Always replenish water.

In the hot summer. Want to find the healthiest way to cool down? Then give up drinks-boiled water is a smart choice.

Carbonated drinks-affect your calcium and iron.

Carbonated drinks include all kinds of soda, flavored soda, cola, flavored cola and all kinds of carbonated drinks.

There are four reasons why carbonated drinks should not be drunk often:

Carbonated drinks contain gas, namely carbon dioxide.

Carbon dioxide can stimulate the secretion of gastric juice. Too much stomach acid can easily lead to bloating, loss of appetite and reduction of daily food intake. Insufficient intake of nutrients in diet will affect normal growth and development, learning effect, sports performance, work performance and health.

Carbonated drinks contain sugar.

A can of 355 c.c cola contains about 35 grams of sugar, equivalent to 140 calories, equivalent to half a bowl of rice. However, only the calories are equal, but the nutrients are quite different. Because sugar only contains calories, there are no other nutrients at all. It is empty card food or junk food with calories. If you drink it often, it will increase, increase your weight and make it easier.

Phosphoric acid, another component of carbonated drinks

Phosphoric acid can reduce the absorption of calcium in the body and affect the normal development of bone growth and height. Children and adolescents in growth and development need enough calcium to make bones grow and develop normally, maintain good bone metabolism and achieve the best bone density, so they are not suitable for drinking carbonated drinks. In addition, phosphoric acid will hinder the absorption of iron, which is one of the main substances for making blood. Once the iron element is insufficient, it will cause iron deficiency anemia, and it will grow rapidly. Children also need enough iron to make blood quickly, especially adolescent girls. The demand for iron is higher. Because every menstrual period will lose a lot of iron, girls who love to drink carbonated drinks are more prone to iron deficiency anemia.

Caffeine contained in various colas.

Caffeine can stimulate myocardial contraction, accelerate heartbeat and respiration, stimulate gastric acid secretion, which is harmful to the stomach and intestines and has diuretic effect. Old people are prone to dehydration. Long-term drinking will be addictive. Once you don't drink it, you will feel uncomfortable, listless or have a headache. If you drink too much caffeine for a long time, that is, more than 200 mg per day, there will be chronic poisoning phenomena such as indigestion, headache, insomnia, nervousness, trembling, irritability and rapid heartbeat. Caffeine is found in cola, tea and coffee. A can of 355 ml coke contains 65 mg and a can of 350 mg. 120mg。 A cup of instant coffee contains 85-200mg. Therefore, if you drink more than three cans of coke a day, or a can of coke, plus a can of oolong tea and a cup of coffee, you will consume more than 200mg of caffeine, which will easily lead to chronic poisoning for a long time.

Non-100% fruit juice beverage-same as sugar water.

Non-100% fruit juice beverage. Refers to the general market juice which is not marked with 100% pure juice.

Generally, fruit juice on the market contains about 30% raw juice or less, and the rest is sugar, citric acid, vitamin C, pigments, spices and so on.

Non-100% juice drinks should not be drunk frequently for two reasons:

1. Drinking non-100% fruit juice is no different from drinking sugar water, which will increase a lot of unnecessary calories, form a bad eating habit of loving sweetness, and endanger dental health.

2. The added vitamins, minerals or fiber easily mislead people into thinking that drinking it can replace eating vegetables and fruits, while ignoring the importance of taking vitamins, minerals and fiber from fresh fruits and vegetables, which seriously affects the cultivation of correct eating habits.

Disadvantages of tea beverage-carbonic acid.

Tea drinks. Refers to all kinds of beverages containing tea ingredients, such as black tea, oolong tea, green tea, packaged tea, milk tea, coffee black tea, lemon black tea and so on.

There are four reasons why tea drinks containing tea leaves should not be drunk often:

1. Tea contains caffeine. The effects of caffeine on the body have been mentioned in carbonated drinks.

2. Tea also contains tannin. Tannin can reduce the digestion and absorption of nutrients in gastrointestinal tract, especially the absorption of iron. Drinking tea and drinks often can easily reduce the absorption of iron and cause ischemic anemia, especially for young girls.

3. If it is milk tea, the "milk" in milk tea includes whole milk, skimmed milk or creamer, in which creamer is not milk, but made of coconut oil, maltodextrin and spices. It contains a lot of saturated fat, which will increase cholesterol in the blood and harm the heart and blood vessels.

4. Tea drinks contain a lot of sugar, which is one of the reasons for weight gain and is also harmful to dental health.

Sports drinks-not suitable for ordinary people.

Sports drinks refer to all kinds of drinks marked to supplement physical strength and electrolytes.

Sports drinks mainly contain sugar, carbon dioxide, sodium, potassium and magnesium. They are only suitable for strenuous exercise. After sweating a lot, you can drink it in moderation. If people drink it regularly, it will increase the burden on the kidneys and bury the risk factors of hypertension.

Coffee and drinks-not good either.

Coffee refers to all kinds of drinks containing coffee ingredients. Coffee drinks contain caffeine, sugar, creamer and other ingredients. Its harm to health is the same as that mentioned above.

Boiled water is better.

From the health point of view, for the sake of healthy and normal growth and development, we should drink boiled water and reduce the number of carbonated drinks, non-100% fruit juice drinks, sports drinks, tea drinks and coffee.
