Most people who drink water seem to have never cared about the timing, usually thirsty before drinking.

In fact, the timing of drinking water is very particular. Drinking water at the right time not only quenches thirst, but also reduces the risk of cardiovascular disease to a certain extent.

Blood viscosity is related to drinking water. Studies have shown that drinking 6 to 7 glasses of water a day is less likely to cause cardiovascular accidents than drinking 2 to 3 glasses of water.

Experts teach you to use a cup of "bed water" to effectively prevent the heart.

A cup of "life-saving water" anti-heart attack before going to bed

The blood of the human body also has a biological clock, and the blood viscosity is one after another under the scheduling of the biological clock.

The most viscous time of the blood is from midnight to early morning, because people are basically in a state of sleep, unable to drink water, but they lose water all the time (breathing, sweating, urinary ... especially hot summer), and the amount of excretion is considerable. .

Related studies have shown that the human body discharges 450 ml of water on average every night.

If the elderly do not drink water all night, the blood viscosity will increase, which may lead to thrombosis and induce cardiovascular diseases such as angina pectoris, myocardial infarction and cerebral thrombosis.

If you drink water properly before bedtime and at night, dilute the blood concentration, you can reduce the incidence of cardiovascular disease.

Need to be reminded that drinking water before going to bed should not be too much, half a cup on the line, otherwise it will cause frequent nights, affecting sleep. You can also drink a small amount of water 100 times a day during the day to keep your body hydrated and don't drink too much water at night.

2 standards for a "life-saving water"

Drinking water seems to be a normal thing, but it is not so simple to drink water. If you meet the following two points, you can be called a "life-saving water."

Temperature: equivalent to body temperature

Drinking cold water can cause the gastrointestinal mucosa to suddenly become cold, which causes the original open capillaries to contract, causing gastrointestinal discomfort and even diarrhea.

Excessively hot water is also not recommended, because high temperature water enters the esophagus, easily destroys the esophageal mucosa, and even increases the risk of esophageal cancer.

The water temperature should not be too hot or too cold, and it can be roughly equivalent to body temperature.

If the body itself has kidney disease or some metabolic diseases, you should follow the doctor's instructions to avoid burdening the body and aggravating the original disease.

Speed: small mouth slow drink

Drinking water quickly and quickly will dilute the blood quickly, increase the burden on the heart, and easily swallow a lot of air together, which may cause snoring or bloating.

The correct way to drink water is to put a bite of water in your mouth and swallow it several times.

Especially the following two kinds of people should pay more attention to hydrating before going to bed.

Middle-aged and elderly people with underlying diseases such as diabetes, high blood pressure, and high blood lipids. The blood is thicker than the average person, and should drink water properly before going to bed;

Middle-aged and elderly with atrial fibrillation. The atrial contraction function is affected, the blood is easily stagnated in the atrium, and a thrombus is formed. The detachment of the embolus will travel to other places along with the blood circulation, causing pulmonary embolism and cerebral embolism.

It is worth noting that middle-aged and elderly people with heart failure should drink as little water as possible before going to bed. Because they have incomplete heart function, they are prone to edema in the body. Drinking more water will only aggravate the condition.
