Other reasons for having closed curtains, or venetian blinds, might be because the room was not in use and because neighbours showed similar behaviour. For example, participant P15, aged 36, keeps her blinds in her east-facing bedroom completely closed because the bedroom overlooked the common pathway where neighbours passed. She mentioned that most people had closed curtains in her block, which fronts onto the pathway. In the morning, the wake-up light, rather than the morning sun, illuminated her bedroom.
