How many minutes does the body need to absorb a cup of water after drinking it, and after how many hours the water is completely eliminated, and what are the benefits of water for the body?
The answers will surprise you.
In a study conducted by researchers at the University of Montreal and published online in the European Journal of Applied Physiology, researchers gave 36 volunteers 300 milliliters of water, in which water molecules contain "deuterium", an isotope of hydrogen that contains On a proton and a neutron instead of just a proton, "to track water molecules.
Water consists of the union of an oxygen atom with two hydrogen atoms, while the water used in the study consists of the union of an oxygen atom with two deuterium atoms.
The researchers found the following:
The body began to absorb the water and reached the blood plasma within about 5 minutes.
Half of the water (300 ml) was absorbed in about 11-13 minutes.
The water was absorbed completely within 75-120 minutes.
When a person urinates 10 minutes after drinking water, they are not urinating from the water they just drank.
But drinking water will raise fluid levels in the blood enough to stimulate urination.
The body needs 50 days - yes, 50 days - to completely get rid of the cup of water that a person drank, and the water is disposed of through vital processes such as urination, sweating, and with stool.
What are the functions of water in the body?
Protect the body from dehydration.
Carrying nutrients into the body.
Transferring waste products out of the body.
It forms a medium in which vitamins, minerals, sugars and amino acids (which make up proteins) dissolve, enabling the body to use them in the metabolism and energy industry.
It forms a lubricant that reduces friction between different parts of the body, and absorbs shock due to its liquid nature.
Regulating body temperature through its role in the process of sweating by evaporation, absorbing excess heat in the tissues.
It gives the blood its volume and keeps its pressure from falling.
When water decreases in the body, the volume of blood decreases, and this stimulates a part of the brain called the hypothalamus (hypothalamus) to release a series of signals that make us feel thirsty, which prompts us to drink water and replace it.
If the body fails to obtain water, symptoms of fatigue, weakness, and loss of appetite appear on it, then it progresses to loss of sleep, poor concentration and rapid breathing, and then ends in death.
Doctors recommend drinking at least two liters of water to 3 per day in order for the body to perform its vital functions and reduce the risk of kidney stones, which increases the likelihood of decreased urine volume and high concentration.
Water not only exits the body through the skin and urine, but also through the lungs.
A person must maintain an adequate amount of fluid in his body for the body's functions to function smoothly, so it is advised not to wait until we feel thirsty, but rather to drink water from time to time.
Avoid excessive drinking water right before bed
Despite the importance of drinking water for the body and its benefits, some doctors and health experts warn of the danger of drinking water right before bed, according to a report in Deutsche Welle.
Doctor Vanita Sima Chiang, a specialist in urinary tract diseases, explained the reasons that make drinking water before going to sleep harmful to health.
She explained that drinking large amounts of water shortly before going to bed prompts a person to get up during the night in order to enter the bathroom to urinate, which negatively affects sleep hours and their quality.
The doctor indicated that the matter is not only dependent on the inconvenience that results in waking up, but also on its dangerous consequences for health.
It doesn't depend on the total number of hours you spend in bed, but the amount of deep sleep that you get.
In other words, even if you get a full 8 hours of sleep, waking up in the middle of the night can disrupt your sleep cycle, leading to poor focus and limited energy the next day.
Lack of deep sleep can also lead to a weakening of the immune system, according to Dr. Heather Muday, a specialist in functional medicine. Especially in light of the pandemic.
Experts advise to avoid this problem to abstain from drinking water 3 or 4 hours before bed, except in cases of thirst.
