DEFINITION

  • Sleep disruptions exist when sleep is insufficient to support adequate alertness, performance, and health, either because of reduced total sleep time or fragmentation of sleep by brief arousals.
    • May be volitional or involuntary
  • Acute sleep deprivation refers to no sleep or a reduction in the usual total sleep time, usually lasting one or two days.
  • Chronic sleep deprivation (also called sleep restriction) exists when the individual routinely sleeps less than required for optimal functioning.
