The body of each person consists of 60-80% ofwater - its amount depends on our age, level of physical activity and state of health. Water plays an important role in the work of all internal organs, therefore, with its lack, a person begins to think poorly and feel physical weakness. A disadvantage may well arise, because we regularly remove fluid through urine, sweat, and even breathing. It is quite easy for adults and healthy people to maintain water balance in the body, because for this you just need to eat right and on time. But babies, the elderly and workers who are forced to work in the heat are very susceptible dehydration. But what happens to the human body with a lack of water? This question has already been well studied and scientists have an extremely complete answer to it.
Dehydration - This is a painful condition of the body caused by a lack of water. A person begins to feel weak when water balance is reduced by 1%. A loss of 20-25% of water is already fatal.
About what happens to a person withdehydration, Science Alert told New Zealand researcher Toby Mundel. With a lack of water in the body, a person feels thirst: in the throat it becomes dry and all he wants is a glass of cool water. According to Toby Mündel, when a person begins to feel thirsty, he is already dehydrated. He explained this by the fact that the feeling of thirst lags far behind the actual deficiency of fluid in the body. It follows from this that if a person does not want to drink, this does not mean that he is well with the water balance.
If a person loses at least 1% of hisoptimal indicator of water balance, he already at this moment begins to feel bad. Ailments are directly related to the malfunctioning of the brain, which is 70-80% water. Fluid in the brain is necessary for brain cells to produce what are called neurotransmitterswhich are required for transmission nerve impulses between cells. Therefore, when the amount of water in the body decreases, the brain begins to work worse.
Nerve impulse - this is the so-called "wave of excitement", through which brain cells exchange information with each other.
And from the work of the brain, as we know, it dependsthe functioning of all other organs of the human body. In humans, coordination of movements worsens, and blood becomes thick - a large load is imposed on the cardiovascular system. If you do not drink water for a long time, you can weaken so much that when you make one of the movements, you can simply faint. If there is not enough water in the body, a person cannot go to the toilet and sweat - harmful substances begin to accumulate in the body, and the temperature rises.
Daily rate of water
To the question “how much water should I drink per day?”It’s hard to give a definite answer. If you delve into the Internet, you can find out that the recommended norm of water for an adult is two liters per day. But researchers from the US National Medical Academy in 2004 announced that the daily rate of water depends on the gender of a person:
- men should drink 3.7 liters of water per day;
- women daily it is recommended to drink 2.7 liters of water.
But at the beginning of the article we mentioned thatthe optimal water content in the body depends on three factors: age, physical activity and health status. My colleague Daria Yeletskaya even mentioned this - in a material on a similar topic, she showed a table according to which the daily rate of water can be determined by body weight. If a person weighs 60 kilograms, he needs to drink 1.8 liters of water daily. If body weight reaches 80 kilograms, you need to drink at least 2.4 liters.
That's right, but the table is relevant only forhealthy people who do not live in the hottest countries of our planet. But if a person is sick, he definitely needs to increase the amount of water consumed. Indeed, at high temperatures a person sweats a lot, thereby increasing the risk of dehydration. And if a person is sick, then the fluid is lost along with vomiting. Without replenishing the amount of water that has left the body, you can additionally provoke problems with the functioning of the brain and the cardiovascular system.
