Use Colored LED Lights to Relax

Colored LED lights

Getting an MRI or CT scan is typically not a relaxing experience, and patient discomfort, anxiety or agitation can affect the quality of the image. Taking note of businesses that use lighting to create a mood, researchers from Pepperdine University demonstrated that patient unease in imaging centers can be modified with the use of colored LED lights. In a pilot study involving 35 subjects, 43 percent found blue lighting most relaxing, while 31 percent preferred yellow. The least relaxing lighting color was red, according to 69 percent of participants, followed by yellow (17 percent) and green (11 percent). Each subject was given a handheld device to set the hue, intensity and brightness of lighting, and most chose blue. No patient preferred the standard bright, white lighting of healthcare environments. “When given the opportunity to change a single aspect of the environmental or imaging facility experience, patients feel much more in control of the otherwise unfamiliar and uncomfortable setting,” write the authors in the Journal of Medical Internet Research.
