The Phenomenon of Hospital Sun Decks

In the early 20th century, hospitals often featured sun decks where patients could bask in natural sunlight. This practice was rooted in the belief that sun exposure played a therapeutic role in patient recovery, particularly for those suffering from ailments like tuberculosis. Facilities such as the Paimio Sanatorium in Finland, designed by architect Alvar Aalto, exemplified this approach with dedicated sun decks for patients.


However, as medical science advanced, (ahm, we’re using that term with a degree of irony) the emphasis on sun therapy sadly diminished. The advent of antibiotics and other treatments reduced reliance on natural remedies like sunlight. Additionally, concerns about overexposure to ultraviolet (UV) radiation and its link to skin cancer led to a reevaluation of sunbathing practices. Consequently, the once-common hospital sun decks gradually disappeared from medical facilities.

In recent years, there’s been a renewed appreciation for the benefits of natural light in healthcare settings. Studies have shown that exposure to daylight can enhance mood, reduce stress, and even shorten hospital stays. For instance, research conducted at a general hospital in Korea found that patients with better access to daylight had hospital stays that were 16% to 41% shorter than those without. 

Moreover, natural light plays a crucial role in the synthesis of vitamin D, essential for bone health and immune function. While direct sunbathing may no longer be prescribed, modern hospital designs often incorporate large windows, skylights, and open spaces to ensure patients receive adequate natural light. This approach balances the benefits of sunlight with the need to protect patients from potential harm due to overexposure.
