A doctor’s knowledge.. Here’s what he does to reduce the risk of cancer

Doctors and experts agree that drinking water is very important to prevent dehydration and maintain body performance, but on the other hand, researchers say that drinking a lot of water over a short period of time can lead to nausea, shortness of breath, and sometimes death, according to the newspaper “The Wall Street Journal“American.

Researchers say that when a person drinks a lot of water over a short period of time, this can lead to a dilution of sodium in the blood, known as water poisoning. They point out that the condition can be serious when it causes inflammation in brain cells.

Researchers and scientists warn that the development of the condition puts pressure on certain parts of the brain, and that it could lead to coma or death.

Cases of water poisoning are unusual, but they can occur if a person drinks a lot of water in a short period of time, which leads to a loss of balance of electrolytes, that is, minerals and salts in the body, which follow. to reduce sodium levels in the blood.

According to the website “InsideSodium helps maintain blood pressure, a vital function that ensures healthy nerves, muscles and body tissues.

But when the sodium level falls below the normal level due to excessive water consumption, water moves into the cells to perform this function, causing the cells to swell or swell. , which can be life threatening if it happens to brain cells.

Usually the body is more at risk of water poisoning when it drinks a lot of water after exercising for a long time, when the body loses a lot of minerals and salts due to physical exercise and sweating.

The Wall Street Journal quoted University of Utah Nutrition and Physiology Professor Thunder Ghalili as saying, “A person’s kidneys can normally manage about one liter of water per hour.”

Ghalili said: “When you drink more than a liter of water per hour, this could damage the work and functions of the kidneys. “

Mayo Clinic nephrologist Kambiz Kalantari, MD, says that despite the many benefits of drinking water, it is difficult to identify additional benefits from drinking more water than necessary.

Medical academies and experts recommend consuming at least two liters of water per day, and doctors advise that the amount of water a person drinks should not be less than 8 cups of water per day.

A previous study published in the journal “science“The idea of ​​drinking 8 cups of water a day is inaccurate, and it depends on age, body size, climate, activity level, and lifestyle to determine how much water is needed on the body.

The study concluded that drinking 8 cups of water is not necessary, and is not dangerous either, as the body gets rid of excess water through urination.

Kalantari emphasizes that a person’s sense of thirst also changes with age, making it more difficult to know how much water to drink.

American newspaper Mitchell Rosner, a kidney specialist at the University of Virginia School of Medicine, said, “Those who exercise need a lot of water and salt that they lose through sweating with water, electrolytes, and salty snacks to replace the water and salt they lose.”
