A review of the environmental parameters necessary for an optimal sleep environment

What the study found

Noise, temperature, light and air quality each have plausible and documented effects on sleep quality and continuity.

Limitations

Recommended ranges aggregate different populations, bedding systems and climates; many primary studies are small.

Neurodesign interpretation

The bedroom is the clearest example of neurodesign acting through recovery rather than momentary preference. Small environmental disruptions can recur for hours, every night.

Possible design implications

Treat bedroom design as a four-system problem: acoustics, darkness/light timing, thermal microclimate and ventilation.

Why it stays in the corpus

Retain as the core cross-domain bedroom design review.
