日饮水量计算器
根据体重和活动量计算每日推荐饮水量。
饮水量计算器根据您的体重、活动水平和气候估算您每天应该喝多少水。适当的水分有助于肾脏功能、消化、关节润滑、体温调节和认知表现。即使是体重 1-2% 的轻度脱水也会损害注意力和体能。
输入您的体重、活动水平（久坐、适度活跃或非常活跃），以及您是否生活在炎热气候中或正在怀孕或哺乳。该工具以升和杯为单位计算您的每日用水目标，并为您提供如何在全天分配摄入量的实用指南。
"每天 8 杯水"的旧规则只是粗略估计。您的实际需求取决于您的体型、出汗量以及食物的含水量（水果和蔬菜贡献显著）。一个实用的现实检验是尿液颜色——淡黄色表示水分充足，深黄色表明您需要多喝水。
