如何使用「褪黑素剂量参考（按年龄组）」？How do I use the Melatonin Dose Reference by Age Group tool?

参考范围从哪里来？Where do the reference ranges come from?

儿童和青少年按国际儿科睡眠协会（IPSA）2025 年专家共识：未满 2 岁不建议使用，2–3 岁最多 1 mg，4–5 岁最多 2 mg，6–10 岁最多 3 mg，更大的学龄儿童和青少年最多 5 mg，都从 0.5 mg 起。美国儿科学会 HealthyChildren.org 也指出很多孩子 0.5 或 1 mg 就有效。成人按常见的 0.5–5 mg 区间；英国 NHS 的常用剂量是 2 mg 缓释片，专科处方最多每天 10 mg。For children and teens the page follows the International Pediatric Sleep Association (IPSA) 2025 expert consensus: not recommended under 2 years, up to 1 mg at 2–3, up to 2 mg at 4–5, up to 3 mg at 6–10 and up to 5 mg for older school-age children and teens, always starting at 0.5 mg. The AAP's HealthyChildren.org also notes that many children respond to 0.5 or 1 mg. For adults it uses the common 0.5–5 mg range; the UK NHS usual dose is one 2 mg slow-release tablet, with a specialist maximum of 10 mg a day.

为什么没有体重？Why is there no weight field?

公开的指南都按年龄而不是体重给出褪黑素剂量，没有可靠的按体重计算公式，所以本页不使用体重。Published guidance gives melatonin doses by age, not body weight, and there is no reliable weight-based formula, so the page does not use weight.

什么时候会出现警示？When does the page warn?

剂量高于所选年龄组的参考上限时显示警示；超过上限的两倍或超过 10 mg 时显示强烈警示，因为高剂量的血药浓度可持续 24 小时以上。未满 2 岁总是显示不建议使用。It warns when the dose is above the reference limit for the chosen age group, and shows a strong warning above twice that limit or above 10 mg, because high doses can keep blood levels raised for more than 24 hours. Under 2 years it always says melatonin is not recommended.

这能代替医生建议吗？Can this replace medical advice?
