Dangers of sleepiness and fatigue
light switch

When the brain is deprived of adequate sleep, at some point it will go to sleep no matter what the situation.

  • The brain moves rapidly from wakefulness to sleep, like an on/off switch
  • This leads to dangerous situations while performing critical tasks (such as driving)
  • There are warning signs when the brain is close to falling asleep:
    • Difficulty focusing
    • Frequent blinking, heavy eyelids, eye-rubbing
    • Daydreaming or disconnected thoughts
    • Repeated yawning, difficulty keeping head up
    • Feeling restless and irritable
