In the previous article, we mentioned why we need to drink water. We learned that ingesting water is essential for our bodies. So, is the more water you drink, the better?
First of all, let's see what happens if you consume a lot of water in a short period of time.
There are electrolytes in our body's cells (so-called electrolytes are compounds that produce free ions and conduct electricity, usually containing sodium, magnesium, calcium, potassium, chloride, etc.). Electrolytes play an important role in muscle movement, nerve transfer and maintenance of blood pressure in our bodies. Usually the concentration of electrolytes in the drinking water we consume is lower than the concentration of electrolytes in human cells. After a mild excess intake of water, our kidneys actively metabolize excess water to maintain electrolyte concentrations in the body. However, if you consume more water than your kidneys can metabolize in a short period of time, the excess water will have to be absorbed by the cells. This causes in-cell electrolyte concentrations to decrease and cells to swell, causing edema in the body. Worst of all, there's not much room in our skulls for the brain to swell. Once brain cells swell in limited space, they cause headaches, vomiting (the brain's rapid drainage response), spasms and even coma, which is medically called water poisoning.
In fact, water poisoning is rare in ordinary daily life. However, after intense exercise causes the body to lose a lot of water, we should pay special attention. Many athletes engaged in endurance sports have experienced water poisoning, according to statistics, about one-half of marathon professional athletes in their careers have experienced symptoms of water poisoning. This is because, during endurance exercises, the levels of anti-diuretic hormones secreted by the lower pasum brain also increase, helping the body maintain more moisture by reducing water metabolism. This allows athletes to metabolize less water while consuming a lot of water. That's why we can choose to consume sports drinks with electrolytes when we take a lot of water after exercise. In the past, boiler workers in steel mills and dockworkers in ports also had the habit of drinking salt soda to replenish their water.
Now let's go back to the original question, how much water should we have every day?
The most popular saying is to drink eight glasses of water a day, and even many doctors give patients such advice. However, the idea of eight glasses of water actually has no scientific basis, and the one-size-fits-all expression of eight cups, regardless of the size of the cup used by men, women and children, is highly unscientific. According to scientific drinking water recommendations, the daily intake of water is largely related to the external environment and the weight of the human body. Men are generally advised to consume 2.5 to 3.7 liters of water per day, while women consume 2 to 2.7 liters. An individual's drinking water needs are adjusted up and down according to their health status, amount of exercise, age, and ambient temperature around them. And now many studies have shown that for the average person, drinking water when you're thirsty is enough, and that the frequency of drinking is enough for the body.
Here we offer you a gallon water bottles which is bigger than 2 liter. Drink with it, you will have enough water and you don’t have to refill it again and again.
