Clinical studies show that melatonin can be effective for certain sleep disorders, with varying success rates:
- Reduces time to fall asleep by 7-10 minutes on average
- Most effective for jet lag and delayed sleep phase syndrome
- Moderately effective for shift work sleep disorder
The effectiveness can vary significantly between individuals. Research indicates it works best when combined with good sleep hygiene practices, including consistent sleep schedules and proper sleep environment. For chronic insomnia, cognitive behavioral therapy (CBT) is often recommended as a first-line treatment before considering melatonin supplementation.
