It may seem odd that windows in hospitals don't open, given that access to fresh air and sunlight was once considered essential for promoting health. In fact, before the 20th century, every room in a hospital had access to the outdoors. However, in the 1940s, a prominent hospital design consultant named Charles F. Neergaard proposed a layout for a hospital inpatient department that included windowless rooms. This was a shocking proposal at the time, but Neergaard's plan was driven by a desire to streamline nursing unit design and improve efficiency.

Windows in hospitals used to be important for promoting health
Before the 20th century, every room in a hospital had access to the outdoors, including patient rooms, corridors, and even linen closets. Even ventilation ducts and enclosures for plumbing had windows. The importance of fresh air and sunlight was considered a vital aspect of the role of the hospital building in promoting health. However, this perspective began to shift in the 1940s with the emergence of innovative hospital designs that prioritised efficiency over direct access to sunlight and fresh air.
One notable example of this shift was the design proposed by Charles F. Neergaard, a prominent New York City hospital design consultant. In the March 1942 issue of the journal Modern Hospital, Neergaard presented a layout for a hospital inpatient department that included windowless patient rooms. This proposal was considered risky and even shocking at the time, as it went against the traditional understanding of the role of windows in hospitals. Neergaard's plan aimed to streamline nursing unit design by grouping patient rooms into units overseen by a single nursing staff, with corridors providing access to patient rooms and shared service areas.
While the inclusion of windowless rooms in hospitals may be standard today, it represents a significant departure from the historical understanding of the importance of windows in promoting health and preventing diseases. The shift towards windowless hospital rooms prioritises efficiency and modern design considerations over the traditional emphasis on fresh air and sunlight.

In the 1940s, a hospital design consultant proposed a windowless room
In the 1940s, hospital buildings were a mix of efficiently arranged medical treatment spaces and inefficiently arranged nursing units. Nurses had to walk long distances to retrieve basic supplies from service areas. This was the design dilemma that confronted Charles F. Neergaard, a New York City hospital design consultant. Neergaard proposed streamlining nursing unit design, keeping windows in patient rooms but prioritising efficiency over fresh air in adjacent service rooms. His "double pavilion plan" allowed two nursing units to share the same windowless central service rooms, reducing spatial redundancy and travel distances for nurses.
Neergaard's plan also reduced the amount of expensive exterior wall construction and minimised staffing requirements. In 1937, prominent hospital architects Carl A. Erickson and Edward F. Stevens resigned from a committee rather than support Neergaard's proposals. However, rising costs and decreasing revenues made his ideas appealing. By the 1950s, with the advent of antibiotics and improved aseptic practices, the medical establishment believed that patient health could be maintained regardless of room design. Some doctors even preferred the total environmental control offered by air conditioning, central heating, and electric lighting.
Before the 20th century, every room within a hospital had access to the outdoors, due to the belief that disease was caused by dark, stagnant spaces with bad air. Windowless rooms were thought to breed the conditions that led to disease. Large windows in patient rooms and operating rooms could cause problems, such as keeping patients awake and causing temporary blindness in surgeons. However, Neergaard's design treated the hospital as if it were any other building, marking a shift in hospital design philosophy.

This proposal was considered risky and shocking at the time
In the early 20th century, every room in a hospital had access to the outdoors. This was due to the understanding that, while windowless rooms might not directly cause disease, they bred the conditions that led to it. However, in the March 1942 issue of the journal Modern Hospital, hospital design consultant Charles F. Neergaard proposed a layout for a hospital inpatient department that included windowless rooms.
Neergaard's proposal was considered risky and shocking at the time. Before the 20th century, it was common knowledge that access to fresh air and sunlight was essential for promoting health. Neergaard's plan prioritised efficiency over direct access to sunlight and fresh air, marking a significant shift in hospital design.
The proposal was particularly daring given the context of the time. In the late 18th century, epidemics were more prevalent in crowded, urban districts with limited access to fresh air. Patients in large urban hospitals with small windows were more susceptible to cross-infections and secondary infections. Neergaard's proposal to eliminate windows altogether went against conventional wisdom and sparked concerns about potential health risks.
Furthermore, large windows in patient rooms and operating rooms were a common feature in hospitals before the 20th century. While they provided ample natural light and ventilation, these windows also had drawbacks. The glare from the large windows could cause discomfort for patients, keeping them awake, and even causing temporary blindness for surgeons during operations. Neergaard's proposal aimed to address these issues by eliminating windows altogether.
Neergaard's innovative design, which prioritised efficiency and streamlined nursing unit layouts, challenged traditional notions of hospital architecture and sparked debates about the role of the hospital building in promoting health. Despite the initial controversy, his proposal marked a turning point in hospital design, influencing the shift towards more compact and enclosed hospital structures.

Before the 20th century, every room in a hospital had outdoor access
Before the 20th century, hospitals functioned very differently from how they do today. In the 19th century, hospitals primarily served the sick poor, with patients occupying the same bed in a ward for weeks or even months. Nurses provided basic care, but little in the way of hands-on treatment. Hospitals were seen as an environmental antidote to the tenement surroundings of impoverished patients, with clean, bright, and airy rooms. Every room typically had access to the outdoors, with windows in corridors, linen closets, and even ventilation ducts.
The late 19th and early 20th centuries saw significant advancements in medical theories and practices. The development of germ theory gave sunlight and fresh air new purposes, as experiments proved that ultraviolet light was germicidal. Records from tuberculosis sanatoria showed that exposure to fresh air could be curative. However, large windows in patient rooms and operating theatres caused problems with glare, affecting patients' sleep and causing momentary blindness in surgeons during operations.
As medical procedures and efficient workflow became the focus of hospitals in the early 20th century, the limitations of earlier "therapeutic" hospital designs became apparent. To provide a window in every room, buildings could not be wider than two rooms deep, requiring multiple long, narrow wings. The rise of centralized care and the competition for patients led to the construction of larger hospital complexes. The University Hospital in Aachen, Germany, built between 1969 and 1982, is an example of this new model, with medical and technical rooms arranged on a multi-story pedestal.
The second half of the 20th century saw further changes in hospital architecture, with centralized designs that reduced construction and operational costs. The belief that patient health could be maintained through antibiotics and improved aseptic practices, along with a preference for environmental control offered by modern systems, led to windows no longer being considered necessary. By the 1960s and 1970s, even windowless patient rooms became common, reflecting how hospital design had shifted from being a therapeutic tool to facilitating medicine.

Windowless rooms breed the conditions that lead to disease
For centuries, hospital designers based their layouts on the belief that direct access to sunlight and fresh air was essential for maintaining disease-free and health-giving environments. This idea stemmed from the understanding that disease was spread by, or caused by, stagnant spaces with poor air quality. While this correlation was statistically established in the 18th century, the advent of antibiotics and improved aseptic practices in the 1950s shifted the perception of room design's impact on patient health.
However, the notion that windowless rooms breed the conditions that lead to disease has persisted. Sleeping or residing in a room without windows can have adverse effects on both sleep and overall health. One of the primary concerns is the lack of fresh air and inadequate air circulation, creating an environment conducive to the growth of microbes, pathogens, and dust mites. This stale and potentially contaminated air can be uncomfortable and even dangerous to breathe, especially for individuals with respiratory issues.
The absence of windows also impacts temperature regulation, often resulting in uncomfortably warm rooms. This not only affects sleep quality but can also exacerbate underlying health conditions, particularly those related to the lungs and respiratory system. In addition, the limited exposure to natural light in windowless rooms leads to increased reliance on artificial lighting, which can disrupt the body's natural circadian rhythm and negatively impact sleep patterns and overall health.
Furthermore, windowless rooms in hospitals have been associated with increased vulnerability to physical hazards and a lowering of the standard of care due to their influence on the psychological state of both patients and staff. Research has shown that patients in hospital rooms with windows experience faster and more significant improvement in their health than those in windowless rooms. This highlights the importance of considering the therapeutic benefits of natural light and ventilation in hospital design.
While the construction of windowless rooms in hospitals may have been influenced by budgetary constraints and the belief that environmental control through artificial means was sufficient, the potential consequences on patient health cannot be overlooked. Recognizing the impact of the built environment on patient outcomes is crucial for informing future hospital design and ensuring the well-being of patients and staff.
