Is melatonin helpful for sleep disorders, and when should it be used?

Melatonin is a hormone that helps regulate sleep and wake cycles. According to the provided references, melatonin can be beneficial for sleep disorders, particularly in older adults.

1. Use in Older Adults: One study highlights that melatonin is effective in treating insomnia in people aged 55 and older. This is because melatonin production naturally decreases with age, and supplementation can help restore balance.

2. Circadian Rhythm Disorders: Another study explains that melatonin is useful for people with disrupted sleep patterns, such as those caused by shift work or jet lag. It helps by adjusting the body's internal clock to align with the desired sleep-wake schedule.

While melatonin is generally considered safe, it's important to use it appropriately. It is most effective when taken in the evening, about 30 to 60 minutes before bedtime. However, it is always a good idea to consult with a healthcare provider to determine if melatonin is suitable for your specific needs.
