Overnight water is drinkable.

It is very common to drink boiled water overnight in daily life, especially cold boiled water. The boiling water itself is boiled, and the boiling water contains few substances, so the probability of contamination is usually relatively low. Therefore, even boiled water can be drunk overnight.

It's just that some people may worry that leaving boiling water overnight may catch bacteria, leading to a variety of different degrees of reactions. But in most cases, the boiling water is placed in a clean container, and the surrounding environment is relatively clean and there is no obvious pollution. If you don't have any worries, you can re-boil.

Even if there is contamination, re-boiling can kill the bacteria. Therefore, overnight boiled water is drinkable.

Precautions for drinking water

If you drink some water in the morning after waking up, it can help your body replenish water and avoid dehydration. Modern people usually have a heavier taste when eating, and long-term intake of spicy and heavy-tasting food will increase the burden, so drinking a cup of water half an hour after a meal can effectively reduce the burden, and can also clean the mouth to avoid embarrassment when communicating with others.

Many office workers are busy with work and don't remember to replenish water in time after a busy day, so drinking a glass of water before leaving work can make up for the lack of water in the body during the day, and can also relax the mood and reduce the stress and fatigue caused by work, making people energetic. When drinking water, try to choose warm water and avoid drinking cold water.

Overnight water is drinkable, many people feel that overnight water is not drinkable, they feel that there are many harmful substances in the overnight water, because in the process of overnight water has some chemical reactions, producing more harmful substances, and even carcinogens, so these people dare not drink overnight water. However, scientific studies have shown that after a night of water, if it is pure water, there will not be much chemical reaction, and no harmful substances will be produced. Therefore, the overnight water is drinkable, not only the overnight water is drinkable, even if it is a day, as long as it is well protected and there is no dust, it can be drunk if it falls inside.

Scientific studies have found that even after 2 or 3 days of boiled water, the harmful substances produced in it are very limited.

I can drink it.

Overnight water, especially boiled water, can be reheated and drunk if it is well preserved (refrigerator, sealed, etc.) without abnormal changes.

Whether the water can be drunk is related to the length of storage time, whether the storage container is clean, whether the ambient temperature is appropriate, the number of bacteria in the environment and other factors, and has little to do with whether it is overnight.

Water is affected by environmental conditions, and the storage time may be short, and it is not that it cannot be drunk overnight. In general, when the ambient temperature is suitable, the number of bacteria in the environment is low, the container filled with water is clean, the storage time is not long, and the seal is tight, even overnight water can be drunk.

The best time to drink water every day is as follows

AM6:30: After a full night's sleep, the body starts to run out of water, so drink a 250ml glass of water when you wake up.

AM8:30: Early in the morning from the process of getting up to the office, the time is always very tight, the mood is also more nervous, the body will be dehydrated invisibly, so when you arrive at the office, don't rush to make coffee, give yourself a cup of at least 250ml of water!

AM11:00: After working in the air-conditioned room for a period of time, you must give yourself the third glass of water of the day when you get up and move, replenish the lost water, and help relax the tension at work.

PM12:50: Half an hour after lunch, drink some water instead of artificial drinks that make you fat.

PM5:30: Drink another glass of water before leaving the office. If you want to use water to lose weight, you can drink a few more glasses to increase your satiety, and when you eat dinner, you will naturally not overeat.

Overnight water can be drunk.

Because the production of nitrosamine substances requires a suitable environment and precursor substances, but the bacterial substances in the water will lose their activity after boiling, and the nitrate content is small, and there is no basis for the production of a large number of nitrosamine substances.

Therefore, even if the boiling water is left overnight, it will not change the properties of the water itself, and the microbial content may increase, but it will not cause great harm to the human body.

Overnight water treatment method:

When the water is boiled, it is best to put it in a sealed environment, such as a thermos, so that the water does not come into contact with the air and avoid contamination with bacteria, which can damage the health of the human body.

Therefore, as long as it is treated as above, the water can be drunk overnight. However, even if it is sealed. Do not leave the preserved water for too long, and set the deadline at about three days.

Don't be reluctant, otherwise, you will damage your own health and endanger your life.

"Overnight water can't be drunk" is mainly because overnight water contains chemicals such as zero alcohols, oxyphenols, and hydroxyhydrogen, which can cause diarrhea and even produce carcinogens nitrite.

Drink the rest of the boiled water overnight and drink it the next day.

After leaving it overnight, the chemical composition of the water changes subtly, so the taste becomes a little sour. But don't worry, these changes are not noticeably harmful. Because water does not contain proteins or sugars, water spoils differently from ordinary food and is not damaged and decomposed by microorganisms.

However, water does expire, and water exposed to the air for a long time will absorb carbon dioxide, produce acidic substances such as carbonic acid, and reduce the pH value of the water, so the water will have a sour taste when drunk overnight.
