Will scale induce kidney stones? Does boiled water also have a "shelf life"? Remember the 4 principles of healthy water drinking!

As the saying goes, "Food is the most important thing for man, and water is the first priority for food." "8 glasses of water a day" plays a vital role in the health of human skin, blood vessels, and intestines.

Drinking water in moderation and scientifically is a technical job. Amway will help you unlock the correct "posture" for drinking water!

Does boiled water also have a “shelf life”?

Does long-stored water breed E. coli?

There is a saying: Boiled water also has a shelf life. If it exceeds 16 hours, E. coli will multiply in large numbers and it can no longer be drunk.

In fact, there is no scientific basis for this statement, and E. coli cannot be transmitted through the air.

In this regard, the researchers conducted a special experiment:

The researchers divided boiled water into two groups, with and without lids, and left them there for 5 hours, 8 hours, 11 hours, 14 hours, 15 hours, 16 hours and 17 hours respectively, and monitored whether the water contained E. coli.

The results showed that no matter whether there was a lid or not, there was no E. coli in the boiled water placed in each cup after the experimental time.

However, E. coli may contaminate water sources through feces, so it is best not to drink unsterilized water.

Boiled water that has been stored for a long time is not suitable for drinking

The process of boiling water will kill many pathogenic microorganisms. However, after the temperature of the boiled water drops to room temperature, various microorganisms will continue to enter the water and multiply. The longer the water is exposed to the air, the more microorganisms and bacteria there will be, the worse the water quality will be, and the greater the harm to the body will be.

In addition, in seasons or environments with high temperatures and high humidity, if the water is not stored properly, it may be contaminated by mosquitoes, dust, etc., and may also contain other bacteria. It is best not to drink it, especially for children and those with weak stomachs.

What will happen if you drink water with scale for a long time?

Will too much scale in drinking water induce kidney stones? After using the kettle at home for a period of time, there is often a layer of white scale at the bottom of the kettle. There is a rumor that "this is hard water, and drinking too much will cause kidney stones." Is this really the case?

Scale is mostly formed because the water contains more calcium and magnesium ions.

my country's "Drinking Water Hygiene Standard" stipulates that the total hardness of drinking water (calculated as calcium carbonate) should not exceed 450mg/L, which is equivalent to 180mg of calcium in 1L. Adults usually drink no more than 2L of water per day, and the reference daily calcium intake is 800mg, so the maximum tolerable intake is 2000mg.

It can be seen from this that normal drinking of water will not cause excess calcium in the body, nor will it induce kidney stones (abnormal accumulation of calcium in the kidneys is one of the causes of kidney stones).

Secondly, drinking more water can dilute the concentration of calcium oxalate and calcium urate, which can help prevent the formation of kidney stones and even help expel existing small stones.

10 situations to remind you to replenish water!

When should you drink water to achieve the best hydration effect? ​​The following 10 situations remind you that it is time to drink water:

Before going to bed at night

When people are asleep, the water in the body is continuously lost through urination, sweating, and breathing, causing increased blood viscosity and accumulation of metabolites. Drinking water moderately before going to bed can alleviate this phenomenon and reduce the risk of cerebral thrombosis and other diseases. Especially for the elderly, they should not refuse to drink water before going to bed because they are afraid of getting up at night.

Get up in the morning

People are in a physiological state of dehydration after getting up in the morning. Drinking a glass of water before breakfast only takes 20 seconds for the water to enter the blood, dilute the blood quickly, and improve the dehydration at night.

After bathing

After taking a bath, the body will be dehydrated, so you should sip a glass of warm water slowly. Taking a hot bath will increase blood flow, and drinking too quickly will be bad for your health, especially for the elderly.

After turning on the air conditioner for half an hour

The dry air in the air-conditioned room can easily cause the body to lose water, dry out the mucous membranes in the nasal cavity, and even cause bronchitis. If you stay in an air-conditioned room for more than half an hour, you must replenish water in time, such as boiled water, mineral water, lemonade, etc.

When you have a fever

When a person has a high fever, they will dissipate heat in the form of sweating, which consumes a lot of water. At this time, you can drink warm water or warm glucose water in small amounts and multiple times to replenish water. Millet porridge and mung bean soup are also good choices.

When urine turns yellow

Light yellow urine indicates that you have drunk enough water; if the urine is relatively yellow, it is recommended to drink about 500 ml of water immediately; if the urine is khaki, it means that you are severely dehydrated and need to replenish water and seek medical attention in time.

When flying

Many flying discomforts are related to dryness in the cabin. Short-distance passengers are advised to start drinking water before takeoff and drink a small amount of water during the flight. Long-distance passengers should ensure that they drink water every hour, especially in winter when the cabin temperature is high and the body loses water quickly and needs to drink water more.

When you are upset

When a person is in pain and irritability, adrenaline will surge. At this time, you might as well drink a glass of water, and the adrenaline will be discharged from the body along with the water, and your mood may be much more relaxed.

pregnancy

During pregnancy, the blood flow of pregnant women increases exponentially, and they need a lot of water. If they drink too little water, the concentration of metabolic waste will increase, increasing the chance of urinary tract infection, which is not good for the fetus.

During exercise

Exercise consumes a lot of water, especially children, whose water needs are higher than those of adults. In addition to drinking water before exercise, you should also drink water every half an hour during exercise.

Four principles of scientific drinking water

If you want water to work well for your body, you must master four principles:

High-quality water

High-quality water is the first choice for drinking. You can use a water purifier with integrated ultraviolet filtration to achieve 99.99% sterilization. Do not drink or drink less beverages.

Water intake

The average person must ensure 1600 ml of water out of the 2500 ml daily water intake, and the rest of the water can be obtained from other foods.

The correct way is to drink water frequently, two or three sips each time, and don't wait until you are thirsty to drink. In addition, you should focus on three drinking times every day: a glass of water (about 200-300 ml) when you wake up; a glass of water one hour before going to bed; and a glass of water before meals.

Water temperature

Drinking cold water will suddenly cool the gastrointestinal mucosa, causing the previously open capillaries to contract, causing gastrointestinal discomfort or even diarrhea. Overly hot water entering the esophagus can easily damage the esophageal mucosa and induce esophageal cancer.

Therefore, the temperature of drinking water should not be too hot or too cold. The most suitable temperature is 10℃~30℃.

speed

When drinking water, some people are used to "guzzling", but this way of drinking water is not good for health. Drinking a lot of water quickly will quickly dilute the blood, increase the burden on the heart, and it is easy to swallow a lot of air, causing hiccups or bloating.

The correct way to drink water is to hold a mouthful of water in your mouth and swallow it slowly in several times. This will fully moisten your mouth and throat and effectively relieve thirst.
