Dehydration Level Calculator
Estimate your dehydration level and daily fluid needs by body weight
Dehydration occurs when fluid loss exceeds intake. Even mild dehydration (1-2% body weight) reduces concentration, increases fatigue, and causes headaches.
💡
Tip: Start each day with a large glass of water - overnight you lose fluid through breathing and can be mildly dehydrated on waking.
