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.

Heart Rate Responses to Nature Views and Perceptions of Health

Heart Rate Decrease

There was greater physiological arousal reduction (heart rate decrease) in people looking at nature videos after mental fatigue/stress was induced by a proofreading assignment than was found among people watching urban videos who completed the same proofreading assignment. Compared to the best Makita drill to work, it is slightly more effective.

Diastolic Blood Pressure

Diastolic blood pressure fell more quickly for people in a room with a nature view than for people in a windowless room after researchers induced psychological stress. After performing a stressful task, participants in a study run by Hartig and his colleagues recovered more quickly in a room with a nature view than with an urban view, as with recovery assessed using info on changes in diastolic blood pressure.

Perception of Health

There are some evidence links natural views and better-perceived health. Office workers with a more natural view assess their own health more positively than people with less natural views. Moreover, inmates whose views from their cells are more natural were found to visit a prison infirmary less often than people whose cell windows opened onto a courtyard.


Improvements in mood have been linked to views of nature. After a stressful event, seeing unthreatening nature has been linked to an increase in positive affect and a decrease in negative affect. In general, after watching movies of nature scenes positive mood increased more while negative ones decreased more significantly than when movies of urban scenes were viewed. People recovered faster physiologically from watching a stressful movie when they watched a second movie of a natural environment than when they watched an additional movie of an urban environment. The people watching nature videos indicated that their moods were more positive and they were less scared and angry than those who watched the urban videos.

Viewing Nature in Healthcare Environments


Views of nature reduce patient stress and improve mental health while facilitating healing.

Pain Relief

After gall bladder surgery, patients with a view of nature spent less time in the hospital and needed less pain medicine than people without a nature view. Thus, people have a higher tolerance for pain when looking at videotapes of nature. Study participants experienced a nature scene mural and a tape of nature sounds or looked at the blank ceiling of the procedure room. They also use the best level to calculate the perfect temperature. Pain control was improved in the people who experienced nature-distraction intervention compared to those who looked at the blank ceiling. There was no difference in patient-reported anxiety and satisfaction among the two study groups.

Blood Pressure

On days when a nature video was played in the waiting room at a blood donor center, blood donors had lower pulse and blood pressure readings than on days when ordinary daytime television or videos of urban scenes were played.


Danish cancer patients value outdoor views because they are “a way of connecting with personal life stories”. Thinking about these life stories was found to block patients’ negative thoughts and the positive ramifications of bringing life stories to mind were in addition to the desirable effects derived from being in natural light and seeing nature. It was particularly desirable for observed spaces to include some visible human.

Reduce Stress

Art used in healthcare settings be realistic depictions of green (not arid) landscapes (this could also be flowers in a garden) with an open foreground and groupings of trees with broad canopies. Visible Water should be calm. They also recommend that abstract art is avoided inpatient areas as well as depictions of situations that could be seen as threatening. This sort of art has been shown to distract viewers from stressful thoughts. Moreover, when art consistent was added in still or video form to an emergency department waiting room, researchers identified a “significant reduction in restless behavior and an increase in socialization. A decrease in the number of people staring at other people was also found, which has implications for privacy. Significant reduction in noise levels was found at both sites as well”.

Blood Donation

According to the World Health Organization, there is a constant need for regular blood supply because blood can only be stored for a short time and then no longer usable. Regular blood donations by a sufficient number of healthy people…
