“…Blue wavelengths in particular increase effectiveness and improve cognitive function and positive mood (Roehlecke et al 2013). It offers antidepressant benefits more rapidly than medical intervention (Alotaibi et al 2016). Seasonal Affective Disorder (SAD) is most commonly treated by sitting in front of a light box that emits simulated daylight.…”

The surge in student anxiety and stress in universities continues to escalate, and with over 50% of young people now going to university, and finite university support resources available, finding complementary ways to support student wellbeing is essential. Enabling students to recognise, understand and manage their in-the moment stress can empower them to take some control over their own mental health. This paper focuses on female students. It adopts a mixed methodology approach of experiential learning informed by themes of social and technology acceptance. Overlapping methodologies including "what if … ?" scenarios around wellbeing are posed to inspire textile-based concepts as an intervention. The research presents novel approaches and proposes five early design concepts to consider the monitoring, management and prevention of female student stress through the design of crafted, wearer-centred e-textiles. The research is underpinned by both quantitative and qualitative data generated at Janet Coulter is a senior lecturer and researcher in fashion design at Ulster University.

“…Though overall treatment effectiveness may be inconclusive ( 25 ), the dose effect and dose response of light therapy have been hypothesized and explored in numerous protocols, e.g., dose equivalence assumption on a duration × light intensity basis ( 4 , 26 ). Additionally, the temporal pattern has also been found to be related to dose-dependent efficacy and has been studied ( 27 ); for instance, depression severity has been found ( 22 ) or presumed ( 28 ) altering along with varied duration or total treatment period ( 29 – 31 ). Overall, the lack of an accepted standard definition of adequate dosing for experimental light treatment, along with controversial presumptions and results, has made it challenging to assess the effectiveness of such treatment.…”

Circadian light therapy and light dose for depressed young people: a systematic review and meta-analysis

BackgroundEmpirical evidence has shown that light therapy (LT) can reduce depression symptoms by stimulating circadian rhythms. However, there is skepticism and inconclusive results, along with confusion regarding dosing. The purpose of this study is to quantify light as a stimulus for the circadian system and create a dose-response relationship that can help reduce maladies among adolescents and young adults (AYAs). This will provide a reference for light exposure and neural response, which are crucial in the neuropsychological mechanism of light intervention. The study also aims to provide guidance for clinical application.MethodsThe latest quantitative model of CLA (circadian light) and CSt,f (circadian stimulus) was adopted to quantify light dose for circadian phototransduction in youth depression-related light therapy. Articles published up to 2023 through Web of Science, Cochrane Library, Medline (OVID), CINAHL, APA PsycINFO, Embase, and Scholars were retrieved. A meta-analysis of 31 articles (1,031 subjects) was performed using Stata17.0, CMA3.0 (comprehensive meta-analysis version 3.0) software, and Python 3.9 platform for light therapy efficacy comparison and dose-response quantification.ResultsUnder various circadian stimulus conditions (0.1 < CSt,f < 0.7) of light therapy (LT), malady reductions among AYAs were observed (pooled SMD = −1.59, 95%CI = −1.86 to −1.32; z = −11.654, p = 0.000; I2 = 92.8%), with temporal pattern (p = 0.044) and co-medication (p = 0.000) suggested as main heterogeneity sources. For the efficacy advantage of LT with a higher circadian stimulus that is assumed to be influenced by visualization, co-medication, disease severity, and time pattern, sets of meta-analysis among random-controlled trials (RCTs) found evidence for significant efficacy of circadian-active bright light therapy (BLT) over circadian-inactive dim red light (SMD = −0.65, 95% CI = −0.96 to −0.34; z = −4.101, p = 0.000; I2 = 84.9%) or circadian-active dimmer white light (SMD = −0.37, 95% CI = −0.68 to −0.06; z = −2.318, p = 0.02; I2 = 33.8%), whereas green-blue, circadian-active BLT showed no significant superiority over circadian-inactive red/amber light controls (SMD = −0.21, 95% CI = −0.45 to 0.04; z = −2.318, p = 0.099; I2 = 0%). Overall, circadian-active BLT showed a greater likelihood of clinical response than dim light controls, with increased superiority observed with co-medication. For pre-to-post-treatment amelioration and corresponding dose-response relationship, cumulative duration was found more influential than other categorical (co-medication, severity, study design) or continuous (CSt,f) variables. Dose-response fitting indicated that the therapeutic effect would reach saturation among co-medicated patients at 32–42 days (900–1,000 min) and 58–59 days (1,100–1,500 min) among non-medicated AYAs. When exerting high circadian stimulus of light therapy (0.6 < CSt,f < 0.7), there was a significantly greater effect size in 1,000–1,500 min of accumulative duration than <1,000 or >1,500 min of duration, indicating a threshold for practical guidance.LimitationsThe results have been based on limited samples and influenced by a small sample effect. The placebo effect could not be ignored.ConclusionsAlthough the superiority of LT with higher circadian stimulus over dimmer light controls remains unproven, greater response potentials of circadian-active BLT have been noticed among AYAs, taking co-medication, disease severity, time pattern, and visual characteristics into consideration. The dose-response relationship with quantified circadian stimulus and temporal pattern had been elaborated under various conditions to support clinical depression treatment and LT device application in the post-pandemic era.

Background: Several behaviors have been reported to interfere with sleep in otherwise healthy adults, including low physical activity (PA) levels. However, few studies have compared low PA with the other behavioral risk factors of objective sleep impairment, despite the behavior tending to cooccur in highly stressed and affectively distressed individuals. Thus, the authors compared objective and subjective measures of PA and other potential sleep disrupting behaviors as predictors of objective sleep (sleep onset latency, actual sleep time, total sleep duration, awake time, and sleep efficacy) at baseline (T1) and 3 months later (T2). Methods: A community-derived sample of 161 people aged 18–65 years were asked about PA, other behavior (ie, night eating, electronic device use, watching television, caffeine and alcohol use), stress, affective distress (ie, anxiety, depression), and demographics including shift work and parenting young children in an online questionnaire at T1 and T2. PA and sleep were also monitored for 24 hours each at T1 and T2 using actigraphy. Results: Multiple regression analyses indicated that sleep at T1 was associated with PA (ie, total number of steps, metabolic equivalents/time, time spent travelling) after controlling mean ambient temperature and relevant demographics. At T2, longer sleep onset latency was predicted by parenting young children and night time television viewing; shorter sleep duration was predicted by female gender; and awake time and sleep efficacy were predicted by alcohol intake after controlling T1 sleep measures, demographics, and mean ambient temperature. Conclusion: The risk factors for objective sleep impairment included parenting young children and watching television at night, whereas better sleep outcomes were associated with greater engagement with PA.
