Maintaining adequate hydration has numerous health benefits:
Let’s say you weigh 70 kg and perform moderate activity daily. Using the formula: Weight (kg) × 35 ml × Activity Factor, where Activity Factor = 1 for light, 1.2 for moderate, and 1.5 for high activity:
Calculation: 70 Ă— 35 Ă— 1.2 = 2940 ml/day
This means you should aim to drink approximately 2.94 liters of water daily. You can split this into smaller glasses throughout the day to make it manageable.
Yes, excessive water intake can lead to water intoxication (hyponatremia). Stick to recommended daily intake based on your weight and activity.
Yes, hot or humid conditions increase sweat loss, so your water requirement rises.
Yes, but plain water is most effective. Drinks with caffeine or sugar may not fully hydrate you.
