How to read your results
This is a minimum target. Thirst, urine color (aim for pale yellow), and energy levels are better real-time indicators. Coffee and tea count toward hydration — they're about 90% water.

Frequently Asked Questions
每天喝8杯水的规则准确吗？
8×8法则是一个粗略估计。实际饮水需求因体重、运动强度和气候条件而异。一个100公斤的运动员在炎热天气下可能需要4升以上；一个50公斤的久坐人士约需1.7升。
咖啡是否计入每日饮水量？
是的——咖啡和茶约含98-99%的水分，对补水有净正贡献。酒精不计入饮水量，反而会增加身体对水的需求。
