Summary

This completed study looked at how indoor and outdoor lighting affects the health and sleep of 191 adults aged 65 and older in Bologna, Amsterdam, and Tartu. Some participants received a special lamp to use at home. The goal was to see if better lighting could improve sleep quality and overall wellbeing. Results may help guide future city lighting policies.
