Why Hydration Matters 💧
Water plays a crucial role in almost every function of your body:
- Boosts energy & focus – Dehydration can cause fatigue and brain fog.
- Improves skin glow – Keeps your skin hydrated and reduces dryness.
- Aids digestion & weight loss – Water supports metabolism and helps control appetite.
- Flushes out toxins – Supports kidney health and detoxification.
How to Calculate Your Daily Water Needs
The 8-glass rule is too general. Instead, health experts recommend:
👉 Weight-based formula:Your Weight (kg) × 0.033 = Liters of water per day
Example: If you weigh 60 kg → 60 × 0.033 = 1.98 liters (~2 liters).
But this varies if you:
- Exercise or sweat a lot → Add 0.5–1 liter.
- Live in hot climate → Add 0.5–1 liter.
- Drink coffee/alcohol → Add more water to bar
