There is recognition that the research could influence sleep health practices, though some posts focus on general awareness rather than deep policy change.

Abstract in brief

Ambient lighting conditions during wakefulness, such as white light and blue-enriched white light, enhance the body's homeostatic sleep response after extended wakefulness compared to dim light.
Both young and older adults showed faster buildup of slow wave sleep and higher EEG slowwave activity during recovery sleep when exposed to brighter lighting, indicating stronger sleep regulation.
Subjective sleepiness was lower under brighter lighting conditions, but these feelings did not directly correlate with the physiological measures of sleep homeostasis, suggesting that ambient light influences sleep regulation beyond just perception of sleepiness.]
