Why Is Melatonin Important?

Melatonin is a naturally occurring hormone produced by the pineal gland in the brain. It plays a critical role in regulating the body’s circadian rhythm — your internal clock that controls sleep-wake cycles.

As daylight fades, melatonin levels naturally rise, helping to suppress stimulating hormones and signaling to the body that it's time to wind down. This allows the body to shift into a state of rest and regeneration, supporting both mental and physical recovery during sleep.

Maintaining healthy melatonin production is essential for:

• Falling asleep and staying asleep

• Immune system function

• Mood regulation

• Hormonal balance

• Reducing oxidative stress

Disruptions in melatonin production — often caused by blue light exposure at night or irregular sleep patterns — can negatively impact sleep quality and overall health.
