Insomnia and Sleep Disorders: Melatonin is a hormone that plays a crucial role in regulating the sleep-wake cycle. Supplementing with melatonin may help individuals with insomnia or other sleep disorders by promoting the initiation and maintenance of sleep.
Jet Lag: Melatonin supplements are often used to mitigate the effects of jet lag when traveling across multiple time zones. Taking melatonin at the appropriate time may help reset the body's internal clock and facilitate adjustment to the new time zone.
Shift Work Sleep Disorder: People who work irregular or night shifts may experience disruptions in their natural sleep-wake cycle. Melatonin supplements may be used to help adjust to a new sleep schedule and improve sleep quality. Age-Related Sleep Changes: As individuals age, there can be changes in melatonin production. Some older adults may use melatonin supplements to address age-related sleep disturbances.
Seasonal Affective Disorder (SAD): Melatonin may be used as part of the treatment for seasonal affective disorder, a type of depression that occurs at specific times of the year, often during the fall and winter when there is less natural sunlight.
Neuroprotective Properties: Some research suggests that melatonin may have antioxidant and neuroprotective properties. This has led to interest in its potential role in supporting brain health, though more research is needed in this area.
