How the 每日饮水量计算器 works

1

输入你的体重并选择单位(千克或磅)。

2

选择你的活动水平:久坐、轻度活跃、中度活跃、高度活跃,或运动员/每日高强度锻炼。

3

选择你的气候:温和/凉爽、适中,或炎热/潮湿。

4

点击「计算」查看你的每日建议饮水量(升数)、250毫升水杯的数量,以及基础量/活动量/气候调整量的明细分解。

Tips & tricks

  • 结果以升和250毫升水杯显示,而非液体盎司——250毫升接近但并不精确等于美制标准8液体盎司水杯。
  • 明细分解面板准确显示你的总量中有多少来自35毫升/千克的基础比率,以及活动量和气候调整量,让你能看出哪个因素对你的数字影响最大。
  • 有5个活动水平(包括最顶端的「运动员/每日高强度锻炼」),而不仅仅是4个——每个级别增加一个更大的固定量,而不是随运动时间连续变化。

Frequently Asked Questions

我每天应该喝多少水?

一般指南:男性每天需要约3.7升(125盎司/15.5杯)总水量;女性需要2.7升(91盎司/11.5杯)。约20%来自食物。个人需求因体型、活动量、气候和健康状况而异。

咖啡和茶算作饮水量吗?

是的。尽管含咖啡因的饮料(咖啡、茶)有轻微利尿作用,但它们仍然净贡献正向水分——所含的水量超过了轻微的利尿效果。只有非常高剂量的咖啡因才接近中性。

轻度脱水的迹象是什么?

深黄色尿液(目标是淡黄色)、口渴(感到口渴时你已经轻度脱水)、头痛、疲劳、注意力下降和口干。2%的脱水会明显降低认知和身体表现。

计算器是否以盎司显示摄入量?

不会——结果以升和250毫升水杯数量显示,而非液体盎司。250毫升接近但并不精确等于8液体盎司(8液体盎司≈237毫升),因此请将「水杯」数量视为基于公制的量,而非美制标准8盎司量。

可以喝太多水吗?

可以。当你喝的水太多导致血钠被危险稀释时,就会发生低钠血症(水中毒)。这种情况很罕见,但在长时间比赛中过量饮用纯水的耐力运动员中会发生。高饮水量的同时需要补充电解质。
