How does the pineal gland affect the sleep cycle?

Influence on Circadian Rhythm

The pineal gland plays a crucial role in regulating the body's internal clock, or circadian rhythm, by producing melatonin in response to darkness. This hormone signals to the body that it is time to sleep.

Disruption Effects

Disruption of melatonin production, such as due to exposure to artificial light at night, can negatively impact the sleep cycle and overall sleep quality.
