How to hit your water goal easily
Start with 500 ml after waking, then sip consistently every hour. Add extra around training, and avoid large intakes right before bed.
Should I drink water during workouts?
Yes—especially when sessions exceed 45–60 minutes or in humid heat. Small sips throughout are better than chugging at the end.
FAQ
How accurate is this hydration calculator?
It provides a practical estimate using body weight, activity sweat-rate assumptions, environment multipliers, and a simple caffeine offset. Individual needs may vary.
When should I add electrolytes?
Typically when training longer than 60 minutes at high intensity or in humid conditions with heavy sweating.
Does caffeine always dehydrate you?
The effect depends on tolerance and dose, but this tool adds a small safety offset to account for potential increased urine output.
What’s the simplest way to check hydration?
Urine color: aim for pale yellow (levels 1–2). Dark yellow suggests dehydration.
Is it better to drink all water at once?
No—spread it across the day. Large boluses can increase bathroom trips without improving hydration efficiency.
