title: Environmental changes affect sleep patterns: a case study.
abstract: While at a state institution for people with mental retardation Peter averaged 5.30 hr. sleep per night. At his community home he averaged 7.87 hr. per night, a 48% gain. The responsive environment of his new home engaged Peter in positive social activities which may have led to decreased stress and increased personal comfort, enabling him to sleep longer.
