“…A large body of evidence shows that exposure to bright artificial light and daylight is effective in reducing depression and improving patients' mood [43]. Furthermore, research indicates the exposure to light is critical to patient and staff health and wellbeing in healthcare settings [44][45][46]. However, excessive daylight can also cause visual discomfort through glare and distraction, which is affected by window design.…”

There is a growing interest among healthcare managers and designers in moving towards a 'patient-centred' design of health and care facilities by integrating patient perceptions and expectations of the physical environment where care takes place. Increased interests in physical environments can mostly be attributed to our improved understanding of their role in patients' health outcomes and staff productivity. There is a gap in the literature on users' perspectives on physical settings in the context of healthcare. Moreover, the connection of care services with the design of the facility is often overlooked partly due to the lack of evidence. This research was aimed at filling the gap by exploring outpatients' perspectives on design factors related to the areas frequented by them, e.g., hospital waiting areas. A 16-item questionnaire was conducted among randomly selected outpatients in two hospitals in Qingdao, China, with a response rate of 84.3%. Five principal factors were identified: sensory; lighting and thermal; facilities; spatial; and seating design, which agreed with the literature. Non-parametric tests were applied to assess variances in constructed principal dimensions concerning demographic variables. Female outpatients were found to be more perceptive of the 'sensory design' factors than males. The number of previous visits to the hospital was found to be associated with 'spatial' and 'seating design' factors, while respondents' age had an association with 'sensory' and 'seating design' factors. Respondents ranked 'noise' and 'air freshness' and 'cleanliness' as highly important.

“…If the ability of short wavelength light to phase shift circadian rhythms is also reduced in the elderly (and this is likely on the basis of the present results), this may have important practical implications. For example, appropriate lighting adjustments may need to be made to hospitalised and housebound elderly who may not be exposed to sufficient amount of illumination (Campbell et al, 1988;Van Someren et al, 1997;Monk et al, 2000). Furthermore, elderly shift workers may need more short wavelength light of a higher intensity than younger colleagues in order to hasten adaptation to a new shift schedule.…”

“…The effect of light on the brain is mediated by the retinohypothalamic tract and the daily light-dark cycle is the primary synchronizer responsible for entrainment of circadian rhythms to the 24-hour day (Hoban et al, 1991). In an institutional environment, where light levels tend to be very low, residents may not be exposed to sufficient bright light to entrain to the 24-hour day (Campbell et al, 1988;Shochat et al, 2000).…”
