What Is Melatonin?


Melatonin is a hormone produced the pineal gland in the brain. It is responsible for controlling your body's sleep and wake cycle.

Melatonin levels play a key role in your body's sleep schedule. Melatonin levels rise in the evening and then drop again in the early morning hours.

Melatonin can be used for multiple conditions including jet lag, insomnia; insomnia associated with ADHD, and can also be used for shift workers looking to regulate their sleep-wake schedule.

Some have found melatonin is effective for children with autism. These children tend to have disrupted sleep wake cycles and melatonin may be helpful in regulating a healthy sleep cycle.

However, melatonin is not recommended for other children experiencing sleep issues. Those diagnosed with autism should only take melatonin under the care and advice of a healthcare professional.

Melatonin is also extremely effective for sleep disorders in blind people who have trouble naturally regulating their sleep cycles.
