Every person experiences the strongest feeling of thirst at some point. It can appear not only in summer, but also in winter, especially if it is preceded by intense physical activity. As a rule, in order to get rid of it, it is enough to drink a glass of water. It will allow you to replenish the lost fluid in the body, the lack of which causes similar sensations. But what if he is not at hand?
The role of water in the human body
Doctors say that the feeling of thirst cannot be ignored in any case. The human body is almost 60% water. She also takes an active part in many processes taking place in it, and is responsible for the normal operation of all organs.
In addition, it is water that regulates the temperature of the human body, helps to neutralize toxins, ensures the transport of nutrients and oxygen to the cells, and also takes care of the health of tissues and joints. Lack of water causes hypotension, an imbalance of electrolytes, or minerals such as potassium, calcium, sodium and others, cardiac arrhythmias and impaired brain function.
How long liquid does a person need
Experts at the Mayo Clinic (the largest association of multidisciplinary clinics, laboratories and institutes) claim that under normal conditions, “every day, the human body loses up to 2,5 liters of fluid through breathing, sweating, urination and bowel movement. In order for these losses not to affect its functioning, it needs to be replenished “(3,4)… That is why nutritionists are advised to drink up to 2,5 liters of water per day.
According to research from the Institute of Medicine in the United States, 20% of the body’s water comes from food. In order to get the remaining 80%, you need to drink various drinks or consume certain vegetables and fruits with a high water content.
In some cases, a person may need up to 7 liters of water per day, namely:
- 1 When playing sports or prolonged exposure to the sun;
- 2 With intestinal disorders;
- 3 At high temperatures;
- 4 With menorrhagia, or heavy menstruation in women;
- 5 With various diets, in particular protein.
Causes of fluid loss
In addition to the above reasons for moisture loss, scientists have named several more. Some of which, to put it mildly, are surprising:
- Diabetes. The course of this disease is accompanied by frequent urination. This is explained by the fact that at some point the kidneys cannot cope with the load, and glucose leaves the body.
- Stress. Scientifically speaking, over-activity of stress hormones lowers electrolyte and fluid levels in the body.
- Premenstrual syndrome (PMS) in women. According to Robert Kominiarek, a board-certified family physician based in Ohio, USA, “PMS affects the levels of the hormones estrogen and progesterone, which, in turn, affect the level of fluid in the body.”
- Taking medication, especially to stabilize your blood pressure. Many of them are diuretic.
- Pregnancy and, in particular, toxicosis.
- Lack of vegetables and fruits in the diet. Some of them, for example, tomatoes, watermelons and pineapples, contain up to 90% water, so they take an active part in replenishing the loss of fluid in the body.
