Hvass and teammates investigated how lighting urban spaces influence perceptions of experiences there. They determined via a field study in public transportation waiting areas and a laboratory experiment (where one light zone simulated the same sort of waiting area and the other the surrounding urban space) that “participants perceived the atmosphere in the simulated waiting area as relaxed and private when luminance intensity was low.

Pouso and team evaluated how nature exposure influenced mental health during COVID pandemic lockdowns. They report that “Using a survey distributed online, we tested the following hypotheses: 1) People will show greater symptoms of depression and anxiety under lockdown conditions that did not allow contact with outdoor nature spaces; 2) Where access to public outdoor nature spaces was strictly restricted, (2a) those with green/blue nature view or (2b) access to private outdoor spaces such as a garden or balcony will show fewer symptoms of depression and anxiety, and a more positive mood.
Olszewska-Guizzo and colleagues studied links between nature experiences and the psychological state of people who lived in Singapore during its 7 week COVID-19 lockdown (known as a stay-at-home order or SHO). Data assessed were collected before the COVID-19 pandemic and immediately after the SHO ended. The research team determined, by showing participants videos of urban public spaces (Busy Downtown, Residential Green, and Lush Garden) filmed before the pandemic that “Post SHO, brain activity and responsiveness to landscapes changed. . .
Buxton and colleagues reviewed published studies on the implications of hearing nature sounds. They determined that “natural sounds improve health, increase positive affect [mood], and lower stress and annoyance. . . . Our review showed that natural sounds alone can confer health benefits. . . . water sounds had the largest effect on health and positive affective outcomes, while bird sounds had the largest effect on alleviating stress and annoyance.”
Thygesen and colleagues link greater access to green space as a child to lower levels of Attention-Deficit Hyperactivity Disorder (ADHD). They report that when they reviewed data collected in Denmark for “individuals, who were born in Denmark between 1992 and 2007 . . . and followed for a diagnosis of ADHD from age 5, during the period 1997–2016. . . . Individuals living in areas defined by sparse green vegetation . . . had an increased risk of developing ADHD, compared with individuals living in areas within the highest [levels of green space]. . . .
Blut and Iyer investigated the implications of retail crowding. They determined via a meta-analysis of previously published studies that spatial crowding, which is tied to the physical features of a space, such as the space available to a person and the form of that space, degrades store evaluations while human crowding, or the perceived number of people in a store and impressions of the interactions of those people, enhances those assessments: “Managers should also examine if their retail or service setting is perceived as hedonic [pleasure-related], and whether attracting more customers
Ozkul, Bilgili, and Koc studied how the color of light used in a restaurant influences diner experience. The researchers found when “five experiments were conducted in five ambient lighted in different colors. . . . the perception of service quality and the level of satisfaction were higher in red and yellow-lighted ambient than those in blue and green-lighted ambient.” Some technical details: “Yellow, blue, red, and green lights were obtained by covering the surface of white bulbs with colored gelatin. .
Tian, Chen, and Hu looked at appropriate levels of circadian stimulus (CS) by age. They determined that “the effect of the CS increased with CCT from 4000 K to 8000 K at the same age as a general trend; however, the CCT of 2700 K shows a higher circadian impact compared to that of 4000 K for the same age groups. . . . In order to provide sufficient CS, the minimum corneal illuminance for children and elderly is 250 lx and 380 lx, respectively, when the CCT of the light source was 2700 K.
