Multimodal evidence of temperature and sex effects on sleep: sleep physiology, sleep quality, and next-day performance

What the study found

Warmer nights reduced sleep continuity and efficiency; autonomic and next-day outcomes differed across temperatures and by sex.

Limitations

Controlled protocol; generalization to different bedding, climates and age groups requires study.

Neurodesign interpretation

The same room temperature can be a different physiological exposure for different bodies. Shared bedrooms make thermal design a negotiation problem.

Possible design implications

Build bedroom controls with individual variation in mind, rather than one setpoint for all occupants.

Why it stays in the corpus

Retain as a recent multimodal bedroom experiment.
