“…Continuously disturbing the entrainment of endogenous circadian rhythms with external diurnal Zeitgeber rhythms with can weaken the regenerative ability of the organism ( 3 , 4 ). Night work is associated with negative consequences for somatic and mental health ( 5 ) and persistent desynchronization of endogenous rhythms limits cognitive performance ( 6 ). Thus, with the increase in flexible working times, innovative lighting concepts that take particular account of non-visual lighting effects become particularly important.…”

Nowadays lighting projects often include temporal variations of the light, both spectrally and in terms of intensity to consider non-visual effects of light on people. However, as of today there are no specific regulations. Compliance with common lighting standards that address visual aspects of light, often means that only little non-visually effective light reaches the eye. In this practice review we confront existing regulations and standards on visual lighting aspects with new recommendations on non-visual aspects and highlight conflicts among them. We conclude with lighting recommendations that address both aspects.

“…Recognition of current time is one of the most important cognitive skills for human life. If a person lives without clocks, their circadian rhythm can be disrupted, and this can result in various kinds of mental problems [ 3 ]. Particularly, circadian rhythm disruptions are common in older people and are more severe in people with dementia [ 4 , 5 ].…”

Background: In ageing population, it is desirable to reduce the impact of cognitive decline on daily life. While various types of dementia-friendly environments have been proposed, the question still remains regarding whether analogue or digital clocks are friendlier for people with dementia. Methods: In clinical practice, we normally use our original clock reading test (10 analogue and 10 digital clocks) to assess patients’ ability to read a clock. In the present study, a retrospective medical record survey was conducted. Fifty-five participants who had done the test were identified. The result of the test was compared between analogue and digital clocks. Additionally, to assess specific ability to read analogue clocks, an “analogue-digital gap” was defined as the difference between patients’ performance for analogue and digital clocks. Univariate and multivariate analyses were conducted to detect significant factors associated with reading ability specific to analogue clocks. Results: The analogue clock proved less readable than the digital clock, even after adjusting for MMSE total score (p = 0.003). Multivariate analysis revealed reading ability of the analogue clock was significantly associated with MMSE calculation and clock drawing test (p = 0.009 and 0.040, respectively). Conclusions: In the present study, the digital clock was friendlier than the analogue clock for patients with dementia. Compared to the digital clock, reading analogue clocks might require more widespread cognition, such as working memory and visuospatial processing. While our finding was a general tendency, and individual assessment is necessary, it might help the development of personalized environmental adjustments.

“…This rhythm refers to 24-hour cycle that is observed in many physiological variables (e.g., heart rate [17]) driven by exogenous cycles of light and darkness, temperature, and sleep-wake cycle, to name a few [18]. Circadian rhythms have been reported to be an important factor in mental health, alertness and human performance [19], with disruptions causing significant effects on mood, processing speed, and working memory [20], as well as anxiety and depression [21]. Recent research has shown that this rhythm can be quantified with wearable devices [22], thus further pushing for a complete wearable solution.…”

Hospital workers are known to work long hours in a highly stressful environment. The COVID-19 pandemic has increased this burden multi-fold. Pre-COVID statistics already showed that one in every three nurses reported burnout, thus affecting patient satisfaction and the quality of their provided service. Real-time monitoring of burnout, and other underlying factors, such as stress, could provide feedback not only to the clinical staff, but also to hospital administrators, thus allowing for supportive measures to be taken early. In this paper, we present a context-aware speech-based system for stress detection. We consider data from 144 hospital workers who were monitored during their daily shifts over a 10-week period; subjective stress readings were collected daily. Wearable devices measured speech features and physiological readings, such as heart rate. Environment sensors, in turn, were used to track staff movement within the hospital. Here, we show the importance of context-awareness for stress level detection based on a bidirectional LSTM deep neural network. In particular, we show the importance of hospital location and circadian rhythm based contextual cues for stress prediction. Overall, we show improvements as high as 14% in F1 scores once context is incorporated, relative to using the speech features alone.
