This study aimed to clarify the impact of indoor thermal environment on sleep quality. Follow-up investigations on sleep quality (sleep efficiency, amount of deep sleep, sleep latency, and number of nighttime awakenings) and indoor temperature were conducted in winter (2014-2016) before and after moving to houses with high thermal insulation performance. Multiple linear regression analysis showed that sleep efficiency increased by 0.73% per 1 °C increase in indoor temperature during sleep. Increased indoor temperature also improved the number of nighttime awakenings.
