During intense training, the body loses 500-1500 ml of fluid per hour. The calculator will help you calculate the need, taking into account the type and duration of the load.
At temperatures above 30°C, the need for water increases by 30-50%. Before traveling to a hot country, calculate the new normal.
Water speeds up metabolism by 3-8%, helps control appetite and promotes the removal of fat breakdown products.
An additional 300 ml per day is recommended for pregnant women, and up to 700 ml for breastfeeding women. The calculator will calculate the exact rate.
With fever, vomiting or diarrhea, the body loses fluid at an accelerated rate. Each degree above 37°C increases the requirement by 500 ml.
| Weight (kg) | Minimum (ml) | At load (ml) | In the heat (ml) |
