This study is looking at whether scheduled exposure to bright light can help older adults (ages 65-99) with mild cognitive impairment (MCI) sleep better. You would receive one hour of bright light therapy, either by being outdoors or using a special lamp, in the morning and afternoon. The researchers want to see if this light therapy can reduce "sleep fragmentation" (waking up often during the night) after four weeks. The study is currently recruiting about 120 participants. To join, you must have mild cognitive impairment and be over 65. You cannot join if you have severe depression, an unstable medical or mental health condition, or an acute infection.
