Calculate how much water you should drink daily based on your weight, activity level, and climate. Adjusted for hot African climates.
Staying hydrated is crucial for health, and it's especially important in Africa's predominantly hot and humid climates. While the common advice of "8 glasses a day" is a reasonable starting point, your actual needs depend on your body weight, activity level, climate, and other factors. People living in Sahel regions, coastal humid areas, or anyone working outdoors in African heat may need significantly more water than someone in a temperate European climate.
Our water intake calculator uses a weight-based formula (30-35ml per kg of body weight) as the baseline, then adjusts for activity level, climate, pregnancy/breastfeeding status, and caffeine consumption. The climate adjustment is particularly important for African users — living in a hot climate can increase your needs by 30-50% compared to temperate regions.
Use this as a screening and trend tool, not a diagnosis. The useful output is a number, a context band, and a clear next step for a clinic conversation.
This app now has its own benchmarked improvement layer, dashboard handoff, email-gated PDF plan, and a route into the Vitals checkup workflow.
Mayo-style hydration calculators: Hydration tools should record context and avoid one-size-fits-all targets.
Implemented here: Added vitals workflow save/PDF actions and repeat-check dashboard storage.
