Abstract

Sleep efficiency improved from 73% to 86% following bright light therapy in demented nursing home patients.

  • Bright light exposure was administered for 2 hours daily over two weeks.
  • Waking time during nocturnal sleep was reduced by nearly two hours.
  • Improvements in sleep were confirmed by both actigraphy and nursing staff ratings.
  • Effects of bright light therapy were consistent across all participants.
