In recent years, the effects of the physical environment on the healing process have proved to be increasingly relevant for healthcare staff, their patients and their families. Research shows that light impacts human health, the performance of visual tasks, control of the body’s circadian rhythms, and enables critical chemical reactions in the body.
“Studies show that higher light levels are linked with better performance of complex visual tasks and light requirements increase with age. By controlling the body’s circadian system, light impacts outcomes in healthcare settings by reducing depression among patients, decreasing length of stay in hospitals, improving sleep and circadian rhythm, lessening agitation among dementia patients, easing pain, and improving adjustment to night-shift work among staff. The presence of windows in the workplace and access to daylight have been linked with increased satisfaction with the work environment. Further, exposure to light is critical for vitamin D metabolism in the human body.”
