Don't wait for thirst to drink water in the summer

"A man may go without food for three days, but he may not go without water for a day

Regarding drinking water, there have been many remarks in life, such as: boiled water can not be drunk for more than 16 hours, long-term drinking of water with scale is easy to get kidney stones, drink more lemonade whitening .

Boiled water also has a "shelf life" more than 16 hours can not drink?

It is said that boiled water also has a "shelf life", more than 16 hours, E.

In fact, there is no scientific basis for this claim, because E.

In addition, the summer temperature is high, the humidity is high, if the storage is improper, the long-term water may be contaminated by flies, dust, etc.

Drinking water with scale for a long time Is it easy to get kidney stones?

Observing the kettle at home, you can find that there is often a layer of white scale at the bottom of the pot, and there are rumors that "this is hard water, and it is easy to get kidney stones when you drink too much", is this really the case?

In fact, most of the scale is formed

Drink more lemonade to whiten?

"A white cover up a hundred ugliness", summer whitening work is even more unslackable

It is believed that lemons are rich in vitamin C, which can reduce skin melanin and have a certain whitening effect

But it is unscientific to talk about efficacy aside

What is the point of drinking water correctly on hot days?

In the summer, the human body sweats more, and many people only want to drink water when they are thirsty, but at this time, the body is already in a state of water shortage.

The water in the human body accounts for about 60% of the body weight, and even the hard bones contain 22% of the water, once the water is lacking, the light is dry mouth, dry tongue, wrinkled skin, heavy is delirious, and even hallucinations, threatening life

Drink at least 1200ml per day, except for special groups The Dietary Guidelines for Chinese Residents recommend that healthy adults with light physical activity drink at least 1200ml

In particular, the perception function of the elderly will be reduced, and it is necessary to develop the habit

Take the initiative to drink, a small number of times The weather is hot, and some people have just returned from the outdoors and poured water "tons and tons", which is not right

Human kidneys can drain 800-1000ml per hour, if in a short period of time suddenly a large amount of water, blood will be diluted, easy to lead to dilution of hyponatremia, and when water penetrates into the cells, it will cause cellular edema, induce "water poisoning", serious even cause breathing difficulties, cardiac arrest, life-threatening!

Experts suggest that the appearance of thirst is already a sign

Control the water temperature

But it's not that "drinking more hot water" is a good thing
.
Some people like to burn tea, in fact, overheated water (above 65 ° C) is easy to cause burns to the mucosa of the esophagus and form inflammation
.
For a long time, the mucosa of the esophagus is prone to genetic mutations in the process of continuous damage- repair, inducing esophageal cancer
.
In general, the water temperature is about
25 to 37 ° C.

Don't replace water with drinks Some people like to replace drinks with drinks, especially in the summer, a glass of iced drinks can make many people satisfied
.
But this is unhealthy, because the drink is mostly made of sugar and other substances, long-term drinking is easy to increase the risk
of obesity, diabetes, gout and so on.

If you really don't want to drink boiled water, you can add some tea, roses, chrysanthemums, dendrobium flowers, goji berries, etc.
, which are delicious and healthy
.

Drink water in the summer five measures to grasp

Drink lightly and not drink sweet
.
Summer sweating loses not only moisture, but also minerals, vitamins, amino acids and so on
.
Therefore, when it is hot, you should drink some light salt water to supplement sodium, homemade mung bean soup, lemonade, etc.
not only to cool down, but also to supplement vitamins and other nutrients
.

It should be reminded that all kinds of sweet drinks are high in sugar, high in energy, and the nutrients are relatively monotonous, and it is not recommended to drink a lot, let alone be used to replace boiled water
.

Drink slowly
, not quickly.
When drinking water, many people are accustomed to "drinking heavily", but this method of drinking water is not good
for health.
Drinking water quickly and heavily will quickly dilute the blood, increase the burden on the heart, and it is easy to swallow a large amount of air together, which is easy to cause hiccups or bloating
.

The correct way to drink water is to take a sip of water in your mouth and swallow it slowly several times, so as to fully moisturize the mouth and throat and effectively relieve thirst
.

Drink early and not late
.
When there is a condition such as thirst and upset or fatigue headache, it means that the body's cells have begun to dehydrate, and drinking water at this time is already "passive drinking water"
.
Over time, the human body will be in a potentially dehydrated state for a long time, which is not conducive to normal metabolism
.
Therefore, drinking water, like eating, also needs to be regular, change passive drinking to active drinking, and drink water
before feeling "thirsty".

Drinking water also "eats" water
.
The water in fruits and vegetables such as cucumbers, watermelons, and tomatoes is easier to enter cells
than ordinary water.
Therefore, while drinking water, you must also "eat" water
.
In addition, fruits and vegetables are also rich in various antioxidants, a variety of minerals and important B vitamins, etc.
, which are of great benefit to enhancing human immunity, preventing aging and resisting diseases
.

Drink
for people.
Normal people can judge when to hydrate by the color of the urine: normal urine is yellowish, and the color is too dark to hydrate
.

In addition, drinking water should also vary from person to person
.
Patients with acute nephritis and renal failure should not drink too much water, and drink more water
than usual when they have a cold and fever.
