Trait Light Sleeper
Light Sleeper is a physical trait in The Sims 3. It conflicts with the Heavy Sleeper trait and is first available at birth.

Light sleepers toss and turn throughout the night and are woken up by the slightest bump in the night.


  • Sim's sleep is a bit restless and easily disturbed.
  • Sim is like a burglar alarm! If a robber ever steps on the lot when while asleep, the Sim will be up in a flash.

Unlocked interactionsEdit

  • Can "Research Sleep" on computers (has no benefit.)

Player notesEdit

  • Light sleepers receive the "Fully Rested" moodlet less often.
  • Light sleepers are easily awoken by music, children and other noises.
    • A cell phone ringing or someone screaming while Inventing are exceptions to this.
  • Light sleepers will sometimes yawn, even if they're not tired.
