how many bottles of water should i drink a day-pureglassware

👏 👏 👏 Basic formula for scientific daily drinking water method:
Weight (kg) × 30-35ml (e.g.: 70kg people need 2.1-2.5 liters)

Standard bottled water (calculated as 500ml/bottle):
❤️ Ordinary adults: 5-7 bottles
❤️ Exercise/hot days: 8 bottles+
❤️ Sedentary/small weight: 3-4 bottles
Key signals:
1. Light yellow urine is ideal, dark yellow requires immediate water replenishment
2. When thirsty, the body is dehydrated, so drink water regularly
Special adjustments:
❤️ After exercise, add 1 bottle for every 0.5kg weight loss
❤️ High altitude (>2500 meters) +1-2 bottles per day
❤️ 20% of water comes from food, coffee/tea is included in the total amount

💡 The National Academy of Medicine of the United States recommends:
3.7 liters/day for men (≈7.4 bottles) | 2.7 liters/day for women (≈5.4 bottles)
Implementation: Start with 4-6 bottles/day, and adjust according to urine color. Patients with heart and kidney diseases should follow the doctor's advice.
