Resources spent funnelling natural light into healthcare spaces seems to be well spent. Research into the effects of natural light in healthcare spaces has uncovered benefits in cardiac patients, surgical patients, mental health patients, and in healthcare workers themselves. In particular, the best drill bits to the patients and the sickness are light of nature, or sunlight of day cause it helps to provide them vitamin D to there body and bone.
Cardiac intensive care unit patients on the sunny side of buildings have different outcomes than people on the non-sunny side. Thus, women on the sunny side of these units spent less time in the unit and mortality rates, in general, were lower in the brighter rooms.
Scientists in the hospital learned that “both window view and daylight exposure have significant impact on reduced recovery [time in the hospital], some dimensions of perceived pain, and general well- being.” More nature in view and more daylight were best. Among patients recovering from spinal surgery, people in brighter rooms needed less pain medication the day after surgery and indicated that they felt significantly less stressed when they were discharged from the hospital than people who recovered in dimmer rooms.
It is reported that severely depressed patients spent fewer days in a mental health facility, on average, when they were assigned to a sunny room than when they were assigned to a dimmer. All in all, bright natural light helps relieve symptoms of depression and depressed bipolar patients spent less time in mental health facilities during the summer and fall when they had morning sun than when their rooms got afternoon sun. This study has implications for building. Nurses in Turkey who experienced 3 more hours of daylight at work each day felt more satisfied at work and less stressed.
