每日饮水量计算器 Water Intake Calculator

根据体重、活动水平与环境因素，快速估算你每天“建议饮水量”（不含食物中的水分）。
Estimate your daily recommended water intake based on weight, activity, and climate (excluding water from food).

1. 输入参数 · Inputs
建议输入“真实体重”。若你刚运动、刚桑拿或刚大量饮水，体重可能短期波动。
Use your current body weight. It may fluctuate after workouts, sauna, or large fluid intake.
这里的“活动水平”指全天总体活动，不等同于一次训练。
This describes your overall day-to-day activity, not just a single workout session.
若你每天有训练，建议把“总训练分钟数”填在这里（如跑步/力量/球类/骑行）。
If you train daily, enter your total workout minutes here (running, lifting, sports, cycling, etc.).
高温、潮湿、干燥或高海拔都会增加水分流失；出汗多的人也需要上调。
Heat, humidity, dry air, or high altitude increase water loss; heavy sweaters should scale up.
工具会对结果做小幅修正：减脂通常更关注饱腹与训练输出；增肌可能更关注训练量与恢复。
The tool makes small adjustments: fat loss focuses on satiety/performance; muscle gain supports training and recovery.
咖啡、茶不等于“脱水罪魁”，但在你尿频或睡眠受影响时，适当补水会更舒服。酒精会增加脱水风险。
Coffee/tea aren’t “instant dehydration”, but if you’re peeing a lot or sleep is affected, extra water helps. Alcohol increases dehydration risk.
3. 使用说明 · Notes
  • 这是什么？· What is this tool?
    这是一个“快速估算器”，用体重作为基础，再结合活动、运动与环境对饮水量做加减。 它给的是“饮水建议量”，主要指水/无糖饮品等可计入的液体，不把食物中的水分（汤、粥、水果等）严格纳入。
    This is a quick estimator: it starts from body weight and then adjusts for activity, exercise, and climate. It estimates “drinking water” (water / unsweetened fluids) and does not strictly count water from food (soups, fruits, etc.).
  • 计算逻辑（简化版）· Calculation logic (simplified)
    基础值 Base 约 35 ml × 体重(kg) / day（常见的体重法快速估算）。
    活动 Activity 根据你选择的活动水平做小幅上调（全天走动多的人通常更渴）。
    运动 Exercise 每 30 分钟训练 额外加约 0.4 L（出汗越多可自行上调）。
    环境 Climate 炎热/潮湿/干燥/高海拔会增加流失，工具会加 0.3–0.6 L 不等。
    目标 Goal 对结果做轻微修正（减脂 +0.1~0.2 L；增肌 +0.2~0.3 L），让你更容易保持训练与恢复状态。
    Base ≈ 35 ml × weight(kg). Then we add small adjustments for daily activity, add ~0.4 L per 30 min exercise, plus climate adjustment, plus a minor goal tweak.
  • 如何更好地“喝到位”？· How to actually hit your target
    不要一次猛灌：建议“分段喝”，例如起床、上午、午后、晚饭前后、训练前后各补一部分；尿色淡黄通常是个不错的直观信号。
    Don’t chug all at once. Split it across the day (morning / midday / afternoon / evening, plus around workouts). Pale-yellow urine is a practical signal for many people (not perfect, but useful).
  • 训练日 vs 休息日 · Training day vs Rest day
    训练日通常更需要补水，尤其是大重量力量训练、长跑、球类、户外骑行等。休息日可按基础值或略低一点，但如果你很渴、天气很热、或者喝了酒精饮品，就别硬压水量。
    Training days typically require more water, especially heavy lifting, long runs, sports, or outdoor cycling. On rest days you can stay closer to base, but don’t force it lower if you’re thirsty, it’s hot, or you had alcohol.
  • 电解质与“越喝越渴” · Electrolytes & “still thirsty”
    如果你大量出汗，可能不只是缺水，也可能缺电解质（钠/钾/镁）。你可以考虑：在运动后补充淡盐水或电解质饮料（无糖/低糖更好），并在饮食里保证盐分与蔬菜水果摄入。
    Heavy sweating may mean electrolyte loss (sodium/potassium/magnesium), not just water loss. Consider low-sugar electrolytes after intense exercise and ensure adequate salt and whole foods.
  • 重要提醒（安全边界）· Safety notes
    任何计算器都不能替代医疗建议。若你有心肾疾病、严重水肿、低钠血症风险、正在使用利尿剂/某些降压药，或医生要求限水/限盐，请以医生建议为准。
    No calculator replaces medical advice. If you have heart/kidney issues, edema, hyponatremia risk, or take diuretics / certain BP meds, follow your clinician’s guidance.

说明：本工具为“估算/教育用途”，结果会因饮食含水、咖啡因摄入、出汗量、环境温度、体型组成等因素而不同。 建议把结果当作起点，再根据口渴、尿色、训练状态与睡眠情况做微调。
Note: This tool is for estimation and education. Results vary with water from food, caffeine intake, sweat rate, temperature, and body composition. Use it as a starting point and adjust based on thirst, urine color, performance, and sleep.
