Melatonin is most commonly used to treat which sleep disorder?

Melatonin is primarily used to treat insomnia due to its role in regulating the body's circadian rhythm and promoting sleep. It is a hormone that the body naturally produces in response to darkness, signaling that it is time to sleep. By supplementing with melatonin, individuals who have difficulty falling asleep or maintaining sleep can find it helpful in improving their sleep onset and overall sleep quality.

Insomnia, characterized by difficulty falling or staying asleep, can often be linked to irregular sleep patterns or disturbances in the body's internal clock. Melatonin supplements can effectively address these issues by helping to cue the body for sleep at the appropriate times. While other sleep disorders such as narcolepsy, sleep apnea, and parasomnia involve different mechanisms and may require other treatment approaches, melatonin is particularly effective for those experiencing sleep onset and maintenance insomnia.
