Effects of Changing Air Temperature at Different sleep Stages on the Subjective Evaluation of sleep Quality

This study examined how varying air temperatures based on sleep stages impacted sleep quality using an IoT-based temperature control system. Ten participants slept in two settings: one with a constant temperature and another adjusting temperatures according to sleep stages. Results showed that dynamic temperature control improved subjective sleep quality, particularly for deep sleep and reduced awakenings. This approach underscores the potential for using tailored thermal environments to enhance sleep quality, promoting better cognitive function and health.

Optimize bedroom temperatures for sleep by maintaining a consistent but adaptable environment (e.g., cooler during initial sleep stages and slightly warmer during deep sleep). Consider IoT-based or programmable thermostats for personalized temperature settings to improve sleep quality. Benefits are promising but based on a small sample size; applicability may vary.
