What Causes SAD?

  • 24-hour sleep-wake cycle, circadian rhythm, caused by the rise and fall of hormones–melatonin
  • Melatonin is the master sleep hormone, produced in the pineal gland
  • The sleep-wake pattern depends on how well the functioning of the internal circadian clock works, deep in the brain.
  • It works with photo sensors in the eyes to sense darkness
  • The body begins to produce melatonin when darkness falls, one of the factors that cause you to sleep.
  • Melatonin is secreted throughout the night, at dawn it decreases and gradually diminishes – causing you to wakefulness in the morning.
  • When there is a problem with this system, sleep disorders and psychological problems can occur.
