Hospitals are among the most carefully planned environments in the world. Medical infrastructure, circulation, hygiene and safety are designed with precision. Yet one element that quietly shapes the human experience often receives less attention: sunlight.

For many patients, a hospital room becomes their entire world for days or even weeks. In large healthcare facilities, internal rooms and complex planning requirements can limit access to windows and natural sunlight, leaving patients disconnected from the world outside. This raises an important question for healthcare design: how do we bring the experience of sunlight into spaces where architecture cannot provide direct access to it?
