Thermal environment and sleep quality: A review

What the study found

Moderate heat or cold can reduce sleep quality; control of the bed micro-environment may offer a lower-energy route to comfort.

Limitations

The literature includes varied climates, bedding and measurement methods.

Neurodesign interpretation

This suggests a scale shift: the most biologically relevant thermal design may happen in the few centimeters around the sleeper, not only at the room thermostat.

Possible design implications

Pair room-level conditioning with localized bed or airflow strategies where appropriate.

Why it stays in the corpus

Retain as a major sleep-thermal source universe.
