Optimizing bedroom thermal environment: A review of human body temperature, sleeping thermal comfort and sleep quality

What the study found

Body-temperature distribution provides a useful bridge between thermal comfort and sleep quality, which are related but not interchangeable.

Limitations

Field remains dominated by younger participants and simplified temperature metrics.

Neurodesign interpretation

A room can satisfy conscious thermal preference while still producing poor overnight physiology. Neurodesign needs both subjective and objective endpoints.

Possible design implications

Avoid assuming a comfort vote is a proxy for sleep physiology.

Why it stays in the corpus

Retain for the distinction between feeling thermally comfortable and sleeping well.
