Keep your body at optimal levels
Daily water needs, dehydration signs, and effective strategies to protect your performance and health.
Hydration is maintaining adequate fluid levels in the body. Our body is about 60% water, and all physiological processes require water.
Scientifically: Even 2% dehydration can reduce performance by 10-20% (source: ACSM).
Everyone's needs are different.
Formula: Body weight (kg) × 35 ml (average).
Example: 80 kg → 2.8 liters.
Exercise +0.5-1 liter, hot weather + extra.
Tip: Know your weight, set your daily goal.
Thirst means you're already late.
Thirst sensation appears after 1-2% dehydration.
Performance has already dropped.
Tip: Keep a water bottle at your desk, set alarms.
Water alone may not be enough.
Electrolyte loss occurs in long workouts (>60 min) or heavy sweating.
Coconut water, salted water, or sports drinks.
Tip: Homemade: 1 liter water + 1/4 tsp salt + lemon.
Maintains performance.
500 ml before, 200 ml every 15 min during.
After: Replace lost amount (weigh yourself before/after).
Tip: Cold water absorbs faster.
Starts the day strong.
0.5-1 liter water loss overnight.

Myth busted.

3-4 cups a day are fine.
Tip: Excessive caffeine (>400 mg) may have diuretic effect.
Prevents headaches.

Sweating doubles for every 10°C increase.
Drink cold water, wear light clothes.
Tip: Carry an insulated water bottle.
Recognize body signals.
Mild: Thirst, dark urine.
Moderate: Headache, weakness.
Severe: Dizziness, confusion.
