ADORA2A has been shown to be responsible for the wakefulness-promoting effect of caffeine and the 1976T>C genotype (SNP rs5751876, formerly 1083T>C) to contribute to individual sensitivity to caffeine effects on sleep. We investigate the association between six single nucleotide polymorphisms (SNP) from ADORA2A and self-reported sleep characteristics and caffeine consumption in 1023 active workers of European ancestry aged 18–60 years. Three groups of caffeine consumers were delineated: low (0–50 mg/day, less than one expresso per day), moderate (51–300 mg/day), and high (>300 mg/day). We found that at caffeine levels higher than 300 mg/day, total sleep time (TST) decreased (F = 13.9, p < 0.01), with an increase of insomnia (ORa [95%CI] = 1.5 [1.1–1.9]) and sleep complaints (ORa [95%CI] = 1.9 [1.1–3.3]), whatever the ADORA2A polymorphism. Odds ratios were adjusted (ORa) for sex, age, and tobacco. However, in low caffeine consumers, lower TST was observed in the T allele compared to homozygote rs5751876 and rs3761422 C carriers. Conversely, higher TST was observed in rs2298383 T allele compared to C and in rs4822492G allele compared to the homozygote C (p < 0.05). These 4 SNPs are in strong linkage disequilibrium. Haplotype analysis confirmed the influence of multiple ADORA2a SNPs on TST. In addition, the rs2298383 T and rs4822492 G alleles were associated with higher risk of sleep complaints (Ora = 1.9 [1.2–3.1] and Ora = 1.5 [1.1–2.1]) and insomnia (Ora = 1.5 [1.3–2.5] and Ora = 1.9 [1.3–3.2). The rs5751876 T allele was associated with a decreased risk of sleep complaints (Ora = 0.7 [0.3–0.9]) and insomnia (Ora = 0.5 [0.3–0.9]). Our results identified ADORA2A polymorphism influences in the less-than-300-mg-per-day caffeine consumers. This opens perspectives on the diagnosis and pharmacology of sleep complaints and caffeine chronic consumption.

“…Similar data is found among groups with scarce daylight exposure. Data suggest that underexposure to natural light at work may significantly impair sleep and wake disorders in low or non-light exposed workers [12,13]. In one study, sleep started 34 min later, and waking 35 min later, during the dark period (December) compared with brighter photoperiods [14].…”

Delayed Sleep in Winter Related to Natural Daylight Exposure among Arctic Day Workers

et al. 2018

Natural daylight exposures in arctic regions vary substantially across seasons. Negative consequences have been observed in self-reports of sleep and daytime functions during the winter but have rarely been studied in detail. The focus of the present study set out to investigate sleep seasonality among indoor workers using objective and subjective measures. Sleep seasonality among daytime office workers (n = 32) in Kiruna (Sweden, 67.86 • N, 20.23 • E) was studied by comparing the same group of workers in a winter and summer week, including work and days off at the weekend, using actigraphs (motion loggers) and subjective ratings of alertness and mood. Actigraph analyses showed delayed sleep onset of 39 min in winter compared to the corresponding summer week (p < 0.0001) and shorter weekly sleep duration by 12 min (p = 0.0154). A delay of mid-sleep was present in winter at workdays (25 min, p < 0.0001) and more strongly delayed during days off (46 min, p < 0.0001). Sleepiness levels were higher in winter compared to summer (p < 0.05). Increased morning light exposure was associated with earlier mid-sleep (p < 0.001), while increased evening light exposure was associated with delay (p < 0.01). This study confirms earlier work that suggests that lack of natural daylight delays the sleep/wake cycle in a group of indoor workers, despite having access to electric lighting. Photic stimuli resulted in a general advanced sleep/wake rhythm during summer and increased alertness levels.

“…Hammes, J. Weninger, M. Canazei, R. Pfluger, W. Pohl: Die Bedeutung von Nutzerzentrierung in automatisierten Beleuchtungssystemen nicht allgemeingültig spezifiziert werden können, sondern sich auf individueller Ebene different ausbilden. So hängen subjektiv präferierte Beleuchtungsstärken und Farbtemperaturen beispielsweise sowohl vom Alter als auch von der Art der Tätigkeit der Nutzer ab [8]. Außerdem unterliegen Arbeitstätigkeiten oftmals kurzzeitigen, kaum vorhersagbaren Veränderungen [9].…”

Derzeitig erwerbbare Beleuchtungssteuerungen versuchen Anforderungen allgemeiner Nutzerkomfortkriterien wie die normative Mindestbeleuchtungsstärke mittels Allgemeinbeleuchtungen und vordefinierten Kontrollkurven gerecht zu werden. Da diese Lösungen sowohl individuelle Nutzeranforderungen als auch Effekte, die sich aus spezifischen Arbeitsanforderungen ableiten lassen, weitestgehend vernachlässigen, können Akzeptanzraten von Nutzern signifikant in Mitleidenschaft gezogen werden. Darauf zurückzuführende Nutzereingriffe in automatisierte Steuerungen können intendierte Systemperformanzen sowohl in energetischer Hinsicht als auch in der biologischen Wirksamkeit beschränken. Um dem entgegenzuwirken, müssen Nutzerindividualitäten in die Steuerungslogik zurückgeführt werden. Prämisse einer erfolgreichen Umsetzung ist die Differenzierung von Raumausleuchtung und bedarfsorientierter Arbeitsplatzbeleuchtung. Positive Folge dieser Differenzierung ist eine Reduzierung des Energiebedarfs. Im Folgenden berichten die Autoren von ersten Ergebnissen einer Langzeitstudie in einem Großraumbüro mit zonaler Einzelarbeitsplatzbeleuchtung unter realen Arbeitsbedingungen. Die Ergebnisse der Studie führen auf, dass durch geeignete Zonierung der Energiebedarf für Kunstlicht reduziert werden kann. Darüber hinaus konnte über Langzeit‐Monitoring herausgefunden werden, dass Nutzereingriffen, die sich negativ auf den Energiebedarf auswirken, über erweiterte Inbetriebnahmephasen entgegengewirkt werden kann.
