Using Natural Light in Healthcare Spaces


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.

Sunny Side

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.

Viewing Nature to Increase Performance


Below are a series of results with respect to nature and professional performance. While these studies did not take place in healthcare environments it would be logical to extend these results to the professional performance of healthcare workers as the mental and physical well-being of healthcare workers could have indirect implications for patient treatment.

Focused Work

People are better able to do focused work after looking at images of natural environments but performance on focused work is not affected by looking at images of urban environments; “there is quite a body of experimental research supporting the idea that nature helps recovery from attention fatigue”.

More Productive

Data collected from subjects in fMRI machines verifies that looking at nature cuts stress levels and helps us become more productive at doing work requiring concentration after we have become mentally exhausted doing work requiring us to focus.


People with views of green spaces are better able to pay attention than people without them compared to the best chainsaw reviews.

Executive Function

Executive function is better in people living in dorm rooms with natural views than it is for students living in spaces with lower levels of natural elements visible from their dorm windows.

Focus Ability

High school students with views of green spaces are better able to focus on their schoolwork. Researchers learned that “exposure to green spaces on high school campuses result in better attentional functioning than exposure to barren landscapes (views of built spaces) or no exposure to the landscape at all (i.e., spaces with no windows). Students (randomly) assigned to classrooms with nature views performed significantly better than those assigned to barren and no-window conditions. This field experiment confirms that exposure to green space enhances students’ attentional.

Impact to Stress of Work

“Window views to natural elements buffer the negative impact of job stress on intention to quit; the more natural elements, the less the negative impact of job stress on turnover intentions. A [physiological study] has indicated that people are less nervous or anxious when looking at the window view to nature compared with the window view to the city or no window view. Also the amount of outdoor nature contact during breaks at work seems to be associated with less perceived stress and better self-rated ”. All in all, views of nature from a workspace have been linked to lower levels of job stress and better self- reported health.
