Dangers of sleepiness and fatigue

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
