Water is the source of life.

Someone once said on the Internet: "People can go without eating for seven days, but they cannot go without drinking water for three days." Although this sentence has not been confirmed by research, it reflects the importance of drinking water to a certain extent.

You must know that water is an essential substance for the body and is also necessary for body metabolism. Once the body is dehydrated, various cells and organs will be affected, and precious lives may even be lost due to severe dehydration. So, how much water should a healthy normal person drink a day?

The authoritative American medical journal "EHJ" gave the answer: drinking 2 liters of water a day can protect heart health. What exactly happened? The family doctor will take everyone to take a look.

Two liters of water a day makes the heart healthier

This study of "EHJ" comes from the team of the National Heart, Lung, and Blood Institute of the United States. The research members said that through the observation and statistics of the serum of middle-aged people, it was found that when the serum With sodium greater than 140 micromoles, the risk of heart failure and left ventricular hypertrophy increases, so drinking more water becomes the key to reducing sodium concentrations.

This research has also been supported by many people. Up to 11,814 volunteers are willing to participate in this activity. Their average age is about 57 years old, and the male to female ratio is close to 1:1. Over the course of 25 years of follow-up, 1,369 volunteers developed heart failure. An even more surprising finding is that drinking 1.6 to 2.1 liters of water and 2 to 3 liters of water for men every day can help reduce the risk of heart failure and left ventricular hypertrophy.

In order to explore the relationship between dehydration and heart failure, the research team assessed the baseline hydration status of the participants and introduced two tonicity-related variables, namely tonicity-1 and tonicity-2. The latter also combined potassium ions and Sodium ion interaction was included in the assessment.

The results found that within the normal range of serum sodium, for every 1 mmol increase in serum sodium , the risk of heart failure can increase by about 5%. Therefore, you should drink more water to reduce serum sodium and reduce the risk of heart failure.

What time of day is the best time to drink water?

Although research has confirmed that drinking more water is good for your health, you should not blindly drink too much water. According to media reports, Huizhou A 20-year-old woman suffered from dizziness, nausea and vomiting after drinking 2 liters of boiled water in more than an hour.

It is reported that the woman went to the hospital for a color ultrasound examination because she had stopped menstruating for more than a month. She had to hold her urine during the color ultrasound examination, so she drank two liters of boiled water in a short period of time and successfully completed the color ultrasound examination. As a result, she felt confused after returning home. Sometimes she would shout loudly or talk to herself, and her behavior was strange. Therefore, her family sent her to the hospital for medical treatment. After doing blood and head CT examinations, she was diagnosed For acute water intoxication.

The woman's attending doctor explained that because she drank too much water in a short period of time, when the water entered the blood, it reduced the osmotic pressure in the blood, and the body was unable to adjust in time, resulting in water, electrolytes, and acid-base imbalance. . This incident also sounded the alarm for people. Drinking two liters of water a day is very important.

. Drink a glass of water after waking up in the morning.

After waking up in the morning, you are in a state of physiological dehydration. Therefore, you should drink a glass of warm water, which can replenish the lost water, dilute the blood, and help clean the intestines.

. After nap

Drink a glass of water after nap to give various systems of the body time to buffer and help the brain wake up before getting back to work or studying.

. After dinner

Drinking a glass of water after dinner can promote gastrointestinal motility, facilitate food digestion and absorption, and reduce the burden on the gastrointestinal tract.

. Before going to bed

Drinking a glass of water before going to bed can dilute the blood, reduce blood viscosity, and prevent high blood pressure levels.

Warm reminder

Drinking two liters of water a day should be evenly distributed in each time period and drink in multiple times. Pay attention to drinking slowly in small sips. Just drink 100~150ml each time, which is beneficial to the body's absorption. If you sweat a lot, you should drink light salt water, mung bean soup or sports drinks appropriately, which not only replenishes water, but also replenishes the lost electrolytes to prevent electrolyte imbalance . It is worth reminding that you cannot replace boiled water with drinks to avoid obesity and even increase the risk of diabetes .
