How Much Water Should You Drink Daily?

The calculator will calculate how much water you should consume to supplement your daily requirement.

Daily water requirement

Usefull information

In an adult, the daily requirement for water from all its sources is usually 2500 ml, i.e. about 1 ml for each kcal of food consumed. This generally means that in order to maintain the water balance, approximately 1,500 - 2,500 ml of water should be administered as drinks. Solid foods are also a source of water; some products contain a lot of it (95% cucumbers, 94% lettuce, 94% tomatoes, 92% radishes, 87% milk, 85% apples, 85% pears, 79% plums, 75% boiled potatoes, 72% boiled eggs, cooked rice 72%, liver 68%, canned sardines 52%, cooked ham 51%).

The feeling of thirst, as a rule, lags behind the body's need for water. The length of time between the onset of thirst and taking the appropriate action to drink, drink a glass of drink, digest it, metabolize it, and replenish the body's water needs is long enough to risk becoming dehydrated. The loss of 3% of water causes fatigue, headache, dizziness, overheating of the body, greater - stopping sweating and heat stroke. With a loss of 10% of water, dehydration is life threatening. Severe vomiting and diarrhea are a direct threat to life.
