The vital force of nature, or How much you need to drink water a day

Disputes about how much you need to drink water a day for each person, do not cease for many years, not only among supporters of a healthy lifestyle, but also among learned men. Some of them are sure that they need to drink only when there is a natural thirst, while others adhere to the well-known theory of "eight glasses". It was developed by American specialists in the middle of the 20th century and consisted in the fact that a healthy person needs 1 ml of water per 1 kilocalorie of consumed food for a normal drinking regime. The daily ration averaged 1900 calories in those years, so the calculation arose of how much water should be consumed per day for an adult: 1900 divided into 250 ml, which is approximately 8 glasses. And nutritionists from different countries, taking this figure as a basis, never agreed whether to include in this amount the water contained in the foods consumed by man, as well as in the first courses and drinks, or to recommend drinking in pure form. And only at the beginning of the XXI century, in 2004, the official medicine of the United States recognized standards: an adult healthy woman should drink 2.7 liters of water a day and a male 3.7 liters. In this considerable amount of daily liquid should include any water contained in vegetables and fruits, juices, tea and coffee, milk, smoothies, cocktails, first courses and other sources.

The ambient temperature plays an important role: the higher the indices, the more the water "evaporates" during respiration and evaporates from the skin. In the summer, when the thermometer is off scale, doctors advise drinking at least 3 liters of water per day. The answer to the question of how much water to drink per day depends on the quality and quantity of food. Slender Japanese and Mediterranean people, eating seafood and other healthy food, one and a half liters of water a day, while obese Americans with their hamburgers, coffee and cola should consume at least 2.5 liters.

To pregnant women, the daily quantity and quality of the fluid should be determined by the observing physician. Usually prescribed at least 2 liters of fluid per day. The amount of water consumed per day increases with diabetes mellitus, problems with the adrenal glands, thyroid gland and gastrointestinal disorders. A doctor's consultation on how much you need to drink water a day to compensate for the loss of fluid in each individual case must be strictly individual!
