Abstract
Background and purpose: The evaluation of the benefits of daylight has been the subject of extensive research. Other studies have investigated the role and consequences of using sunlight in medical care spaces. On the other hand, treatment spaces often do not have proper lighting. This research aimed to identify the mechanisms by which daylight affects the health and performance of humans and the environment in healthcare centers.
Materials and methods: Due to the wide dimensions of the subject, the research was carried out using the method of scientific mapping of previous studies in order to explain the relationship between the subjects and scientific terms of this field. In order to achieve this goal, the representation and visual presentation of the structure and dynamics of scientific knowledge related to the subject was done by studying 92 scientific documents prepared between 1900 and 2022 AD.
Findings: Studies indicate the function of daylight in four areas of improving patient health (in 7 subgroups), improving staff performance (in three subgroups), environmental health (in 4 subgroups), and reducing electric lighting.
Conclusion: The results showed that natural light improves the psychological and physical condition of patients, enhances employee productivity and satisfaction, and promotes environmental health. Additionally, the use of natural light can help reduce electrical energy consumption. This study provides documented evidence for the design of future hospitals and the improvement of existing hospital conditions, which can contribute to increased operational efficiency, improved health, and enhanced economic-environmental sustainability.
