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?
Why Sunlight Matters in Healing Spaces
Healthcare design has traditionally focused on clinical functionality. Today, there is growing attention to how the built environment shapes the patient experience, including comfort, orientation and emotional wellbeing.
Sunlight holds a unique position because it gives us two things: light and life.
It does more than brighten a room. Its changing intensity and warmth through the day are among the strongest cues for the body's internal clock, the circadian rhythm, which helps regulate sleep and wakefulness.
The connection to the outdoors matters. In a widely cited 1984 study, environmental psychologist Roger Ulrich found that surgical patients whose rooms looked out onto trees had shorter post-operative hospital stays than those whose windows faced a brick wall.
In a room without a window, morning, afternoon and evening start to blur into one. Conventional lighting can make a room bright enough to work in, but it does not change the way the sky does.
A space can be well-lit and still feel disconnected from the outdoors.
For healthcare design, this distinction matters. The goal is not only to make a patient room visible, but to keep it connected to the natural rhythm of the day, even when a window is not possible.
Lessons from Indian Architecture
The relationship between sunlight and human wellbeing has long been present in Indian architecture. Traditional buildings used courtyards, verandas, skylights and open-to-sky spaces to bring natural light deeper into interiors.
These elements were not simply decorative. They connected people with nature, introduced the changing rhythm of the day, and created a sense of openness within the built environment.
Modern healthcare facilities face different challenges. Dense urban environments, large-scale planning and complex medical infrastructure can make direct access to sunlight difficult in certain spaces. This creates an opportunity to rethink how the experience of sunlight can be brought indoors.
Reimagining Sunlight Indoors
This is where SUNROOOF began its exploration.
Founder Ishat Jain looked at how lighting had evolved over time, from incandescent bulbs to tube lights, LEDs and downlights, and questioned why the fundamental experience of indoor lighting had not evolved in the same way.
The question was simple: why had lighting not evolved like everything else around us?
This led to a larger thought: what if the future of indoor lighting is about going back to the original source of light, which is the sun itself.
SUNROOOF was developed around this idea. Four years of research and development, collaboration with engineers and designers, and testing of more than 100 prototypes led to its patented approach to recreating the experience of sunlight indoors.
As Jain explains, "We're actually selling the experience of sunlight indoors."
The Future of Healthcare Interiors
The future of healthcare design may therefore involve looking beyond clinical functionality towards the complete human experience. Medical systems will always remain essential, but the spaces surrounding patients can also support comfort, orientation and emotional wellbeing.
SUNROOOF now has 1,800+ installations, seven product lines, one granted patent and two patents filed, with applications across residential, commercial, hospitality and healthcare environments.
A hospital room is more than a place where treatment happens. It is where people spend some of their most vulnerable moments.
Perhaps the next evolution of healthcare interiors is creating spaces that do more than function.
Spaces that bring back the feeling of sunlight.
