  • The pineal gland is turned on when there is darkness and turned off when there is light.
  • When it's dark, the pineal gland becomes active and produces melatonin leading to an increase in the melatonin levels in the blood and a person starts to feel more sleepy and the levels of melatonin remain in the blood for about 12 hours after which they fall and the state of wakefulness occurs.
  • The levels of melatonin fall sharply in the presence of bright light.
  • Thus, the melatonin hormone is responsible for controlling the sleep-wake cycle.
