褪黑激素 Melatonin × 延遲性睡眠相位症 (DSWPD)
結論：證據分歧
AASM 2015 臨床指引以系統性回顧 + GRADE meta-analysis 正式背書「策略性定時褪黑激素」為 DSWPD 成人首選療法，且 Mayo / Cleveland / Harvard / Sleep Foundation 四大患者衛教來源立場一致支持，療效訊號（提前睡眠時相、縮短入睡潛伏期約 23 分鐘）獲多篇 meta-analysis 重複驗證。

然而 NCCIH/NIH ODS 將同一份 2015 AASM 指引解讀為「weak recommendation、效益是否大於危害仍不確定」，且 effect size 偏小、長期安全性未確立，因此給予 B（中等）而非 A。

Research shows that melatonin reduces the length of time needed to fall asleep and advances the start of sleep in adults and children with delayed sleep phase disorder. In delayed sleep phase (delayed sleep-wake phase sleep disorder), the sleep pattern is delayed two hours or more from a conventional sleep pattern, causing you to go to sleep later and wake up later. 來源↗

支持
For example, a low dose (0.5 to 1 mg) is a starting treatment. This isn't a bedtime medication; you'll need to take it four hours before your desired sleep time. Melatonin is widely available over the counter, but not all are U.S. Food and Drug Administration (FDA)-approved. Look for brands with highly reliable amounts and low fillers. Any medication additions to your routine should always be f… 來源↗

The American Academy of Sleep Medicine (AASM) has recommended that strategically-timed melatonin be used in the treatment of delayed sleep/wake phase disorder in children and adults (without medical or psychiatric comorbidities). The AASM has recommended melatonin not be used for insomnia in adults. In the context of sleep, the use of melatonin supplements plays an important role as a chronobio… 來源↗

In this disorder, a person's natural inclination is to fall asleep and wake up much later than what fits their environment. Lifestyle changes and a set bedtime are often suggested first, but if they do not help, a doctor may recommend trying melatonin supplements. Recommended doses are 3 to 5 mg taken 1.5 or more hours before bedtime. 來源↗

台灣社群普遍將褪黑激素視為調整生理時鐘、解決日夜顛倒與時差的工具，但抱怨抗藥性快、需自行從 iHerb 或國外代購，且台灣屬處方藥不易取得；對「延遲性睡眠相位」一詞直接討論不多，多以「晚睡」「日夜顛倒」「作息不規律」等口語描述。

意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為褪黑激素=安眠藥可長期天天吃
✓
事實誤以為劑量越高越有效，導致一次吞 5–10mg 甚至更高
✓
事實誤以為在台灣可以像保健食品般在藥妝店買到（實為處方藥）
✓
事實誤以為一吃就能立刻調整顛倒作息，忽略光照與行為調整才是關鍵
✓
事實誤以為沒副作用，事實上常見隔日嗜睡、頭痛、多夢、情緒低落
