Hydration and sweat tests
Hydration for athletes, matched to training, weather and your sweat rate
How much you should drink on a hot training day varies a lot from person to person. HabitHelm starts from a sound default and learns from your sweat tests.
- Default target from DGE
- Plus training and weather
- Personal with sweat tests
A water target that grows with you
Your base target follows the DGE recommendation, or you set your own. On training days HabitHelm adds fluid based on sport and intensity. For outdoor Strava sessions with location data, the weather during the workout is taken into account too.
- Quick-add buttons with your usual amounts
- Drinks scanned by barcode and recipes in ml count too
A sweat test is simple
Weigh yourself before and after a session, without clothes and as dry as possible, and note what you drank along the way. HabitHelm works out your fluid loss per hour. You also record whether you were indoors or out and how the heat, sun and wind felt.
With several tests in different conditions, the advice for your sessions becomes more personal. Sweat tests are part of Pro.
Frequently asked questions
How often should I do a sweat test?
Several times, ideally at different temperatures and intensities. Sweat rate changes with weather, training and heat acclimatisation.
Does HabitHelm account for sodium in sweat?
No. HabitHelm works with fluid volume. Measuring sodium loss requires a lab test.
