⭕ ⭕ ⭕ There is no exact water bottle standard, because age, gender and body size vary significantly, and "8 glasses of water" (about 2 liters) is usually recommended.

🔥 Main influencing factors:
• Weight: It is recommended to drink about 30-35 ml of water per kilogram of body weight
• Activity: When doing high-intensity exercise, drink about 350-500 ml every 30-60 minutes of exercise.
• Environment: In hot and humid weather, you need to drink more water.
Estimation of the number of bottles (based on the standard 500ml/bottle):
• In general: about 4-6 bottles is the starting point of the common recommended range.
• When the body is large, active, and the weather is hot: more than 6 bottles are needed.

🔥 Best judgment basis:
. Thirst: Respond promptly and the body is thirsty.
. Urine color: The goal is light yellow or clear, and dark yellow indicates that water needs to be replenished.

🔥 Practical suggestions:
• Drink slowly and in small sips in divided doses
• Drink water for breakfast and always carry a water cup with you
• If you have special health conditions (such as kidney disease, heart failure) or are pregnant or breastfeeding, please follow your doctor's advice to make adjustments.
