With climate change Northern areas of the globe are expected to have less daylight during winters due snow and more cloudiness. While wintertime has been linked mental health problems, role scarcely studied. We examined longitudinal associations for objective exposure global radiation self-reported with symptoms depression sleep problems. Our analytical sample included 15,619 respondents from three Swedish Longitudinal Occupational Surveys Health (2012, 2014 2016). Objective was (MJ/m2, November-January November-February). Subjective based on time outdoors in (<1 hour vs. ≥1 hour, November-January). Symptoms were evaluated using a six-item subscale (Hopkins) Symptom Checklist. Fixed-effects method conditional logistic regression controlled time-invariant participant characteristics by design time-varying covariates added into models. One unit increase four-month averaged associated lower odds depressive (OR 0.69, 95% CI 0.52-0.91). These findings confirmed cumulative 0.91, 0.85-0.98). Individuals reporting winter months likely report 0.72, 0.60-0.82) compared when their <1 hour. Higher three-month suggested protective association suggest that higher may contribute likelihood symptoms.

Comparison between problematic use of social media and YouTube to insomnia among Iranian adolescents: A mediating role of psychological distress

Digital Health, Год журнала: 2024, Номер 10

Опубликована: Янв. 1, 2024

Objective Problematic use of the internet has been linked to emotional and sleep concerns, although relationships with specific types are less well understood. YouTube, as an online platform video-watching features, may attract individuals spend considerable time, for those experiencing problematic be termed social media (PUSM) or YouTube (PUY). Therefore, present study investigated between PUSM/PUY, psychological distress, insomnia among Iranian adolescents. Methods An survey comprising Bergen Social Media Addiction Scale, Depression, Anxiety, Stress-21 Insomnia Severity Index recruited 1352 participants. Results Hayes’ Process Macro showed significant correlations two insomnia, distress a mediator (unstandardized coefficient = 0.096 0.100). Conclusion The findings implied effect in mediating PUSM PUY insomnia.

Feasibility and Efficacy of Morning Light Therapy for Adults with Insomnia: A Pilot, Randomized, Open-Label, Two-Arm Study

Medicina, Год журнала: 2023, Номер 59(6), С. 1066 - 1066

Опубликована: Июнь 1, 2023

Background and Objectives: Light therapy (LT) is used as an adjunctive treatment for sleep problems. This study evaluates the impact of LT on quality sleep-related parameters in patients with disorders. Materials Methods: We performed a pilot, randomized, open-label clinical trial. Fourteen aged 20–60 years insomnia were randomized into control groups (1:1 ratio). The group was instructed to use device that provides bright (6000 K, 380 lux, wavelength 480 nm) at least 25 min before 09:00 a.m. two weeks. A self-reported questionnaire evaluate circadian preference, mood, parameters. analyzed serum cortisol levels clock genes’ expression. Results: Epworth Sleepiness Scale (ESS), severity index(ISI), Pittsburgh Sleep Quality index(PSQI) significantly improved within only after two-week period. When comparing groups, change ESS significant (mean difference, control: −0.14 vs. LT: −1.43, p = 0.021) adjusting baseline characteristics. There no differences or Conclusions: can improve daytime sleepiness disorders; however, further well-designed studies are warranted confirm its efficacy.

Light Therapy in Post-Traumatic Stress Disorder: A Systematic Review of Interventional Studies

Journal of Clinical Medicine, Год журнала: 2024, Номер 13(13), С. 3926 - 3926

Опубликована: Июль 4, 2024

Background: Due to limitations in treatment strategies for post-traumatic stress disorders (PTSD), therapeutic options such as light therapy (LT) have garnered some interest recent years. We aimed review the effectiveness of LT patients with PTSD. Methods: Using PubMed, PsycINFO, Web Science, Cochrane database, ClinicalTrials.gov, and PTSDpubs, we systematically searched papers assessing effect evaluated risk bias included studies using handbook, synthesized our findings following Preferred Reporting Items Systematic reviews Meta-Analyses guidelines (PRISMA 2020). Results: From 140 initial papers, four randomized controlled trials (RCTs) one single-arm study. The study sample size ranged between 15 82, mean age (standard deviation) varied 31.4 (8.8) 44.9 (11.8) years, was applied or six weeks. low three studies, concern two other trials. Most reported no significant differences placebo regarding effects on subjective (sleep quality insomnia severity) objective sleep parameters. associated a improvement PTSD symptom severity RCTs, well greater retention extinction learning. Results depression anxiety were discrepant. Conclusions: This revealed that relevant are scarce, promising concerning symptoms, but inconsistencies Further research projects needed better explore this topic.

Psychosocial characteristics of the general population who habitually use hypnotics: Results from a national survey on drug use among the Japanese

Psychiatry and Clinical Neurosciences Reports, Год журнала: 2024, Номер 3(3)

Abstract Aim The aim of this study was to examine the characteristics habitual hypnotic users in Japan. Methods This nationwide, cross‐sectional survey used self‐administered questionnaires. Data were collected from four national surveys conducted every 2 years between 2015 and 2021. participants Japanese individuals who had taken prescription hypnotics past year or never them. We divided 13,396 into three groups compare social background status taking medication controlled drugs, drinking, smoking among groups: people use habitually daily (habitual [HUs]), them only occasionally (occasional [OUs]), do not (hypnotic non‐users [NUs]). compared perception using HU OU groups. Results HUs more likely be older, unemployed, anxiolytics analgesics than NUs. main reasons for alleviating insomnia reducing anxiety, whereas reason improving joint pain. Additionally, group a higher proportion smokers group. There no difference drinking drugs have concerns about their side‐effects OUs. Conclusion analgesics, smoke heavily, take with regarding side‐effects. These results may help encourage appropriate hypnotics.

Abstract This study assesses the effectiveness of pre-sleep dim light therapy (LT) as a non-pharmacological intervention for insomnia in adults, focusing on its impact sleep quality and circadian rhythms. Conducted over two weeks, randomized trial involved 40 adults with disorders. Participants were divided into control group an LT group, latter receiving warm-colored exposure before bedtime. The methodology combined subjective questionnaires, objective assessments through actigraphy, molecular analyses clock gene expression blood cells. Key results indicated significant improvements group’s efficiency, 30-minute advancement Dim Light Melatonin Onset compared to group. Molecular analysis revealed notable reduction CRY1 expression, implicating LT’s influence regulation. While study’s small sample size short duration limit scope, findings suggest potential effective, non-drug approach treatment. advocates expanded research larger, more diverse cohorts longer periods further validate efficacy medicine.

The Origin of Natural Neurostimulation: A Narrative Review of Noninvasive Brain Stimulation Techniques

OBM Neurobiology, Год журнала: 2024, Номер 08(04), С. 1 - 23

Опубликована: Ноя. 29, 2024

This narrative review of the literature on noninvasive brain stimulation techniques observes four neurostimulation domains: light therapy, photobiomodulation, a group within transcranial electric current and magnetic field stimulations, low-frequency sound including vibroacoustic rhythmic auditory stimulation. The aims to determine whether or not different approaches rely upon similar physicochemical sequence actions. study identifies relevant hypotheses about processes at cellular level underlying data analysis reveals that mitochondria activity will likely play central role in stimulations implemented by approaches. Additionally, mother-fetus neurocognitive model gives insight into conditions natural fetal nervous system during pregnancy. Drawing these findings, article supposes hypothesis origin gestation. presents requisites nature-based technique, called Acoustic Photonic Intellectual Neurostimulation (APIN), derived from studying components.
