Daily water needs

VIEW:569 DATA:2021-09-01

Water is an extremely important liquid for the body.
The loss of liquids at 1% of body weight impairs thermoregulation and thirst occurs at this level of dehydration, with dry mouth appearing in approximately 3%. Vague discomfort and loss of appetite appear at 2%. The threshold for impaired exercise thermoregulation is 1% dehydration, and in decreases of 4% a 20-30% reduction is seen in work capacity. Difficulty concentrating, headache and drowsiness are observed in 5%. Tingling and numbness of the extremities can be seen in 6%, and collapse can occur in about 7% of dehydration. A 10% loss of body water from dehydration is fatal.
Thus, the correct concentration of water in the body is very important.
But given the extreme variability in water requirements, which are based not only on differences in metabolism but also on environmental conditions and activities, there is no single level of water intake that ensures adequate hydration and optimal health for half of all people. apparently healthy under all environmental conditions.
Therefore, an adequate intake (AI) was established as the reference value for water intake for healthy individuals and populations.
The amount of water needed to replace losses is the absolute requirement. While requirements are impossible to accurately predict except under controlled conditions, recommendations are standards to be used in evaluating and planning diets for individuals and groups, and in setting policy.
Dietary Reference Intakes (DRI) for water are shown in the Tables. Representing data acquired by the US Department of Medicine.
When looking at the table, we see that there are variations for age and sex. Thus, it is very complicated to define a daily water recommendation value in general. As indicative data, 2.5 liters of water is used per day, but for healthy individuals and adults, knowing that the feeling of thirst is the foundation to replenish the body's water.
But a view that one has little desire to drink water for a long time is a warning sign to consult a professional. Observing the color of urine can also be a factor in looking for a professional.
The use of water is the sum of water from food, with direct water sources.
We will leave a link to access data from the World Health Organization regarding the water needs of individuals.
