What Causes Microsleep?

The greatest factor as to what causes microsleep is the lack of sleep. Insomnia, working night shifts, or not getting enough quality sleep are the main reasons episodes occur, amongst other reasons. Having any kind of sleep disorder can manifest in microsleep, such as:

  • Obstructive sleep apnea: it causes a blockage in your upper airway which interrupts your breathing while sleeping. This is a problem because your brain doesn’t get enough oxygen and it triggers daytime sleepiness.
  • Narcolepsy: Narcolepsy causes daytime drowsiness, sleepiness, and microsleep episodes because of it.
  • Periodic limb movement disorder
  • Circadian pattern disorder

While the causes of microsleep are many, there isn’t a definitive reason as to why it happens. Most medical scientists believe that microsleep occurs because a part of your brain falls asleep while others try to remain awake. The parts of the brain that fall asleep do it because of the before-mentioned disorders, while the rest of the brain tries to combat it.
