Abstract Introduction Light exposure at night is associated with altered sleep behavior and impaired sleep satisfaction, in part due to suppressing the release of melatonin. According to a National Sleep Foundation poll, 90% of people report using electronic devices within an hour of bed at least a few times per week. This study aimed to examine how use of EyeJust, a blue light filtering screen protector applied to laptops and tablet devices, impacted sleep. Methods A within subjects, pre-post intervention design was implemented. Adults (n=24) who self-reported regular blue light exposure after sunset and eye strain participated in a 6-week study (3 weeks of baseline followed by 3 weeks of product use). Intervention consisted of the use of blue light filtering screen protectors on iOS devices used after sunset. Sleep was measured objectively each night using SleepScore Max and by self-report. Participants also reported level of eye strain each night. Multilevel regression and paired t-tests were used to test for statistical significance. Results Across participants (75% female; age 21-50, avg. 37), there were 850 nights of sleep measured. When measured pre-post, many aspects of perceived sleep improved when using the screen protectors: sleepiness at bedtime, falling asleep in the preferred amount of time, ability to sleep through the night, feeling rested in the morning, sleep quality, and satisfaction with sleep (ps<.05). When measured daily, improvement was seen in eye strain, perceived time to fall asleep, perceived awakenings, and time spent awake at night (ps<.05). Objective sleep improvement was found in a subgroup of younger adults (age 21-35). They spent more time in bed (p=.03) and slept longer (6 hours, 40 minutes on average during baseline vs. 6 hours, 50 minutes during intervention; p=.04). This subgroup also had more REM sleep as reflected by a 2% increase in MindScore (measure of REM sleep; p=.04) Conclusion Using blue light filtering screen protectors helped improve sleep, measured by self-report and objectively, especially among younger adults. This intervention may help reduce the negative impact electronic devices have on sleep. Support (if any) EyeJust

Blue light is known to have a multitude of negative effects on the health and well-being of someone who is frequently exposed to the harmful light. Blue light glasses are able to provide temporary relief from blue light exposure through filtering out concentrations of blue light, discontinuing the transfer through the retina of the eye. The experiment consists of three reading comprehension tests, all of equal difficulty and length. There are two treatment groups: wearing blue light blocking glasses and not wearing blue light blocking glasses. After participating in the experiment, participants also answered a short survey in regards to their experiences with blue light during school and outside of school. The results of the study were inconclusive, showing little to no correlation between wearing blue light blocking glasses and improved test scores. The survey allowed for further discovery about the negative implications resulting from blue light exposure, as many participants felt blue light has harmed their health and focus both in the classroom and outside of school. Since there was no statistical significance between treatment groups, considerations should be taken into perspective for future research to ensure more accurate results. Overall, blue light blocking glasses did not improve the ability to retain more information for high school student participants.

Abstract Introduction Snoring can disturb the sleep of snorers as well as their bed partners. Recent technological advances allow objective measurement of sleep and snoring in the comfort of the bedroom. This study examined effects of a non-medical contactless snoring solution on snoring and sleep in snorers and their partners. Methods Self-reported snorers (n=29; 72% male; age 25-59 years, avg. 43; BMI<30) with non-snoring bed partners tracked their snoring nightly with the Do I Snore or Grind app while using the snoring solution at home (527 total nights across participants). During this time, partners tracked their own sleep nightly using ResMed S+. In addition, self-report data were collected from both snorers and partners. A within-subjects, pre-post design was used, comparing a 2-week baseline period to 2 weeks of nightly product use. Multilevel regression and paired t-tests were used to test for statistical significance. The snoring solution (Smart Nora) included a pillow insert that gently inflates when early sounds of snoring are detected, enabling breathing to return to normal. Results Objectively-measured average snoring reduced from 10% of the night when not using the product to 9% during the first week of use and 7% during the second week of use (p<.05). Partners perceived the snoring as less loud and less severe when the product was used. At the end of the study, no partner described the snoring as severe. Objectively-measured sleep of partners revealed a 16% decrease in wake after sleep onset (p<.05). Prior to product use, they spent an average of 38 minutes awake after falling asleep (approximately 9% of their sleep period). This decreased to 34 minutes during the first week of product use and to 32 minutes during the second week. Product use also led to improvements in the perceived sleep of snorers and their partners, including ability to sleep through the night without waking up, overall sleep quality, and feeling rested upon waking in the morning (all ps<.05). Conclusion By reducing the amount of snoring, the contactless snoring solution improved objectively-measured sleep in snorers’ bed partners. Also, the perceived sleep of both snorers and their partners improved. Support (if any) Smart Nora

Watching Tv

Abstract: Nowadays, watching television has become an integral part of children's daily activities. Albeit, TV can have a negative impact on their eyes due to the produced blue light. In the spectrum of light, this blue light is acceptable to the eye but it can cause eye damages by the free radicals produced. The risk of the damage depends on the light length and the exposure intensity. This study aimed to determine whether there is a correlation between the distance of watching TV and the duration of exposure to the blue light from TV with the refraction by measuring visual acuity. This was a cross-sectional study. The population was students of grade 1 to grade 5 of the GMIM 20 elementary school, Manado. Samples were 30 students who underwent visual acuity measurement. The results showed a P-value > 0.05 by using a linear regression. The correlation of the distance of watching TV and the duration of exposure to the blue light with the visual acuity of the right eyes showed a P-value of 0.184 and of the left eyes a P-value of 0.967. Conclusion: Among the GMIM 20 elementary school students in Manado there was no correlation between the distance of watching TV and the duration of exposure to the blue light of the television with eye refraction. Keywords: television, blue light, exposure.     Abstrak: Dewasa ini, televisi telah merupakan alat informasi dan hiburan yang terintegrasi dalam aktivitas keseharian anak-anak.

Abstract Introduction This study examined if an air purifier in the bedroom would improve sleep on a broad sample of healthy people (non-smokers without allergies) with sub-optimal sleep living in urban and suburban areas. This way of testing has the advantage of providing insight into the effectiveness of a product under real-life conditions, yielding more ecologically valid results. Methods 36 adults whose objective data indicated suboptimal sleep participated in an 8-week field study. A within subjects, pre-post intervention design was implemented, comparing 4 weeks of nightly product use to 4 weeks without using the product. Intervention consisted of the use of an Alen BreatheSmart 45i air purifier in the bedroom for 24 hours a day during the duration of the intervention period. Sleep was measured objectively with SleepScore Max every night and by self-report. Multilevel regression and paired t-tests were used to test for statistical significance. Results Across all participants there were 1591 nights of tracked sleep. Participants (55% male, age 25-74, avg. 44) showed improvement in both objective and perceived sleep during the intervention. While using the air purifier, there was a small but significant improvement in objective sleep quality (p<.05). In the subgroup of participants who had the poorest objective sleep at baseline (n=16), there were significant improvements while using the air purifier, reflecting improved sleep continuity after falling asleep: fewer awakenings during the night, decreased time awake during the night, increased sleep efficiency, and increased sleep maintenance (all ps<.05). Self-report data showed that, when using the air purifier, participants felt they fell asleep faster, woke up fewer times, spent less time awake at night, and were better able to sleep through the night. In the morning, they were more likely to feel well-rested. They also felt satisfied with their sleep more often and had better sleep quality (all ps<.05). Conclusion Using the air purifier in the bedroom can improve sleep. Objectively measured sleep improvement supported self-reported sleep improvements, especially in the subset of participants who showed compromised sleep at baseline.

The current study investigated the associations between female perceived fatigue of elite soccer players and their sleep, and the associations between the sleep of players and soccer games. The sample included 29 female elite soccer players from the Norwegian national soccer team with a mean age of ~26 years. Perceived fatigue and sleep were monitored over a period of 124 consecutive days. In this period, 12.8 ± 3.9 soccer games per player took place. Sleep was monitored with an unobtrusive impulse radio ultra-wideband Doppler radar (Somnofy). Perceived fatigue was based on a self-report mobile phone application that detected daily experienced fatigue. Multilevel analyses of day-to-day associations showed that, first, increased perceived fatigue was associated with increased time in bed (3.6 ± 1.8 min, p = 0.037) and deep sleep (1.2 ± 0.6 min, p = 0.007). Increased rapid eye movement (REM) sleep was associated with subsequently decreased perceived fatigue (−0.21 ± 0.08 arbitrary units [AU], p = 0.008), and increased respiration rate in non-REM sleep was associated with subsequently increased fatigue (0.27 ± 0.09 AU, p = 0.002). Second, game night was associated with reduced time in bed (−1.0 h ± 8.4 min, p = <0.001), total sleep time (−55.2 ± 6.6 min, p = <0.001), time in sleep stages (light: −27.0 ± 5.4 min, p = <0.001; deep: −3.6 ± 1.2 min, p = 0.001; REM: −21.0 ± 3.0 min, p = <0.001), longer sleep-onset latency (3.0 ± 1.2 min, p = 0.013), and increased respiration rate in non-REM sleep (0.32 ± 0.08 respirations per min, p = <0.001), compared to the night before the game. The present findings show that deep and REM sleep and respiration rate in non-REM sleep are the key indicators of perceived fatigue in female elite soccer players. Moreover, sleep is disrupted during game night, likely due to the high physical and mental loads experienced during soccer games. Sleep normalizes during the first and second night after soccer games, likely preventing further negative performance-related consequences.

Metacognitive awareness of memory failure may take the form of the “blank in the mind” (BIM) experience. The BIM experience informs the person of a temporary memory failure and takes the form of a disruption in the flow of consciousness, of a moment of no content in awareness. The aim of the present study was to examine the psychometric properties of the Blank in the Mind Questionnaire (BIMQ) designed to tap the BIM experience and differentiate it from other memory-related experiences, such as searching but not having in memory a piece of information (i.e., lack of knowledge). The participants (N = 493) were 249 younger adults (18–30 years old) and 244 older adults (63–89 years old) of both genders. Confirmatory factor analysis applied to the BIMQ confirmed a three-factor model with interrelations between the factors. The first factor represented the experience of lack of knowledge, the second represented the experience of BIM, and the third the person’s negative affective reactions to memory failure. The internal consistency of the three factors ranged from Cronbach’s α = .80 to .88. Convergent validity was shown with correlations of the BIMQ factors with self-report measures of cognitive and memory failures, and to the negative-affect subscale of the Positive and Negative Affect Schedule (PANAS).

The purpose of this article is to provide background information and the current understanding of a less familiar cause of female breast cancer; exposure to ultraviolet light at night. Breast cancer is a common disease that causes significant morbidity and mortality in women. There are several risk factors for breast cancer, most of which are genetic and environmental in nature. An often-overlooked risk factor is exposure to blue light during night shift work, which decreases melatonin production. One of the many cancer-preventing properties of melatonin is to limit estrogen production. Increased lifetime exposure to estrogen is a well-known cause of breast cancer. Awareness of nighttime blue light exposure as a breast cancer risk factor by women doing night shift work and those exposed to nighttime light via smartphones and laptops, is essential information to know so that protective measures can be taken.

Objective Marijuana use is associated with placenta-mediated adverse pregnancy outcomes including fetal growth restriction, but the mechanism remains uncertain. The objective was to evaluate the association between maternal marijuana use and the feto-placental weight ratio (FPR). Secondarily, we aimed to compare placental histology of women who used marijuana to those who did not. Study Design This was a secondary analysis of singleton pregnancies enrolled in a multicenter and case–control stillbirth study. Prior marijuana use was detected by electronic medical record abstraction or cord homogenate positive for 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid. Prior tobacco use was detected by self-report or presence of maternal serum cotinine. Stillbirths and live births were considered separately. The primary outcome was FPR. Association of marijuana use with FPR was estimated with multivariable linear modeling adjusted for fetal sex, preterm birth, and tobacco use. Comparisons between groups for placental histology were made using Chi-square and stratified by live birth and stillbirth, term and preterm deliveries, and fetal sex. Results Of 1,027 participants, 224 were stillbirths and 803 were live births. Overall, 41 (4%) women used marijuana during the pregnancy. The FPR ratio was lower among exposed offspring but reached statistical significance only for term stillbirths (mean 6.84 with marijuana use vs. mean 7.8 without use, p < 0.001). In multivariable modeling, marijuana use was not significantly associated with FPR (p = 0.09). There were no differences in histologic placental features among those with and without marijuana use overall or in stratified analyses. Conclusion Exposure to marijuana may not be associated with FPR. Similarly, there were no placental histologic features associated with marijuana exposure. Further study of the influence of maternal marijuana use on placental development and function is warranted to better understand the association between prenatal marijuana use and poor fetal growth.

ABSTRACTObjective: Few studies have used a combination of objective and self-report measures to examine neuropsychological and behavioral functioning in parents of children with attention-deficit/hyperactivity disorder (ADHD). This study examined attention and inhibitory control in the parents of preschool children who were rated as “at risk” for developing ADHD as compared with parents of controls.Methods:Preschool children (N=53) were divided into at risk for ADHD and control groups based on parent and teacher ratings of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ADHD symptoms. One parent of each child was administered an identical pairs Continuous Performance Test (CPTIP), a Go/No-Go task, and the Brown Attention-Deficit Disorder Scale for Adults.Results: Parents of preschoolers at risk for ADHD showed a pattern of responding on measures of vigilance characterized by slower reaction times and increased commission errors as compared with parents of controls. There were no significant group differences on self-report measures on the Brown Attention-Deficit Disorder Scale for Adults.Conclusion: Parents of preschoolers at risk for ADHD appear to exhibit cognitive processing deficits that may not be evident using self-report measures. Further research is needed to more clearly identify the specific nature of these neuropsychological deficits and to determine whether they have a negative impact on their children.
