✅ Organizations, with the help of ergonomists, should consider such changes in the workplace, and nature-based solutions as strategic programs for improving well-being rather than merely applying a temporary strategy that changes the physical condition of a building or its landscape.
As a new paradigm of basic ergonomic knowledge, human connection with nature should be considered in the design of the work environment with the aim of promoting human health and well-being (2). Man's preference for the characteristics of nature, which may change through experience and culture, is the result of gradual evolution (8). The mismatch between adaptive developmental characteristics and the modern environment leads to an incompatibility, which ultimately leads to stress and health problems (9). The two main theoretical frameworks of Stress Recovery Theory (1983) and the Attention Restoration Theory (1987) (11) argue that people are physiologically and psychologically demanding to be present in natural environments and helping them coping with mental fatigue. Employee health and well-being are affected by a variety of factors. Nature as a new paradigm in job ergonomics and its role in relation to human well-being has not been well studied and explained. Therefore, the aim of this study was to investigate the results of the link with nature on employee health, especially welfare, in the form of a systematic review study.
Searching Scopus, PubMed, Google scholar, Medline and science direct databases, all articles related to Biophilic Design and Health and Welfare Design using Biophilic, Performance, Well-being, Nature and Health keywords in with the criteria of publishing articles from 2000 onwards were assessed. An initial general search led to 210 related research articles. Persian articles (due to low number) and duplicate articles indexed in different databases were deleted. The selection of papers was done considering indicators such as being dedicated to at least one of the various dimensions of health (including mental and physical health) and human well-being, as well as indexing the article in reputable databases. Finally, 25 articles were selected for the present review.
Tables 1 to 5 present the results of the study of the effects of biofilm components such as color, light, plants, natural and artificial landscapes, and natural sound on health and well-being.

Color
Color seems to have more imposed, emotional, and confusing effects on interior design (39). Although people perceive colors similarly, people's preferences vary between country and culture. In addition, men and women appear to react differently to color because women are more sensitive to the effects of light and saturated colors (40). Based on the review of the texts, there is no agreement on the most suitable color for the interior. In general, the appropriate color for the office interior is white, beige or neutral (41). It is also recommended that the walls be light in color and the ceiling white. In general, the effects of colors can be influenced by factors such as age, social norms, and working conditions (41).
Lighting
Proper lighting is essential for successful, safe performance, a sense of comfort and enjoyment of the interior. The results of studies have shown that having natural light in the workplace causes peace of mind, job satisfaction and reduced work leave and as a moderator of workplace stress (9).
Plants
Plants have invisible features such as pleasant smell, air filtration and reduction of building disease syndrome. Therefore, identifying pollutants and selecting some plants in air pollution treatment can be very effective in improving the indoor air quality of the building (9). For example, ferns have a high ability to remove formaldehyde pollutants from the air (44). However, the exact performance of plants in improving indoor air quality is not clear. For example, some plants, including pots and pesticides, provide the conditions for the growth of microorganisms and can add other volatile organic compounds to the environment (44).
Natural and artificial landscapes
Creating natural landscapes is inexpensive and does not take long to be effective. Nature-facing windows create health, job and life satisfaction, and high tolerance capacity, and also help reduce eye strain by creating different focal lengths of the eye (46).
Natural images in the workplace reduce anger and stress, and with the presence of plants, they may increase job satisfaction, physical, mental health, and productivity (21). The use of artificial materials similar to natural materials in interior design (such as artificial laminate flooring with wood and wallpaper design of plants and foliage) seems appropriate due to the remembrance of nature (47).
Sound
Studies show that the sounds of nature can be helpful in relieving stress and unpleasant feelings. Of course, not all such sounds are pleasant. Some bird sounds are reminiscent of threats based on the intensity, stimulation, and loudness of the sound, causing irritation in individuals and preventing them from regaining stress. The white sound created by natural sounds, such as the sound of the ocean or waterfall, covers the unpleasant effects of sound and increases the focus on the presence of other distracting sounds (40).
Biophilic design patterns and effective ways to create symbolic nature at home provide a high level of well-being and health for individuals by meeting the inherent need of human connection with nature. However, today's work environments lack the most basic principles of biophilic design. Therefore, human factor engineers along with designers should pay serious attention to the use of biophilic design in work environments. On the other hand, since most of these studies are related to developed countries, more internal research is needed on how to influence natural patterns and proposed solutions with cultural and regional limitations in mind.
