Light Bulbs That Help You Sleep

Sleep is a problem in Gail Conn’s household. Her teenage son studies late into the night and her 88-year-old mother, who suffers from dementia, gets agitated at night. To tackle the problems, Ms. Conn looked up — at her light bulbs. In her family’s apartment on East 49th Street in Midtown Manhattan, she replaced the existing lighting in all three bedrooms with bulbs designed to help the body sleep at night and stay alert during the day. In the lamp by her mother’s bedroom chair, for example, she placed a Good Night bulb by Lighting Science, with depleted blue spectrum light to help lull her to sleep.
