Thermal comfort is crucial in satisfaction and maintaining quality sleep for occupants. In this study, we investigated the comfort temperature in the bedroom at night and sleep quality for Indonesian students during summer and winter. Eighteen male Indonesian students aged 29 ± 4 years participated in this study. The participants had stayed in Japan for about six months. We evaluated the sleep parameters using actigraphy performed during summer and winter. All participants completed the survey regarding thermal sensation, physical conditions, and subjective sleepiness before sleep. The temperature and relative humidity of participants’ bedrooms were also measured. We found that the duration on the bed during winter was significantly longer than that during summer. However, sleeping efficiency during winter was significantly worse than that during summer. The bedroom temperature of the participants was in the range of comfort temperature in Indonesia. With the average bedroom air temperature of 22.2 °C, most of the participants still preferred “warm” and felt “slightly comfortable” during winter. The average comfort temperature each season calculated using the Griffiths method was 28.1 °C during summer and 23.5 °C during winter. In conclusion, differences in adaptive action affect bedroom thermal conditions. Furthermore, habits encourage the sleep performance of Indonesian students.

Abstract The comfort temperature and sleep quality of Indonesian residing in Japan during summer might be different from Japanese. As an extended previous research, this study aimed to compare the thermal comfort and sleep quality between Japanese and Indonesian students. Male Indonesian and Japanese students aged 20-35 years participated in this study. The participants completed a survey regarding thermal sensation before sleep. During sleep, actigraphy was used to monitor sleep. Additionally, the temperature and relative humidity of the participants’ bedrooms were recorded. The findings of this study indicated that Indonesian students’ bedroom temperature and relative humidity were not significantly different from those of Japanese students during the summer. Most of Indonesian students preferred neutral, like the Japanese students. According to a thermal comfort survey, Indonesians had the same sensation as Japanese (slightly comfortable). However, the Griffiths method revealed that the mean comfort temperature of Indonesian was higher than those of Japanese students. We also discovered that Indonesian students had shorter duration on bed and sleep minute than Japanese students. Furthermore, the sleep rate of Indonesian students was comparable to that of Japanese students. In conclusion, Indonesian students as tropical native became capable of adjusting to the hot and humid conditions in temperate climate, Japan.

Abstract This was a prospective case-control study aimed to explore the sleep quality, especially sleep-related disorders, among chronic obstructive pulmonary disease (COPD) patients with high risk of acute exacerbation, and to determine the risk factors. We enrolled COPD patients with acute exacerbation or health control visited the first hospital of China Medical University from October 1st, 2017 to October 28th, 2018. The subjective and objective sleep parameters were compared among them, and then the stepwise multiple regression analysis were performed. We found that COPD patients with high risk of acute exacerbation had decreased subjective and objective sleep quality. Patients with COPD-obstructive sleep apnea overlap syndrome revealed decreased slow wave sleep than patients with COPD alone. The subjective sleep parameters were correlated with the frequency of acute exacerbation, dyspnea index and Epworth sleepiness score. The objective sleep parameters were related to the degree of airflow obstruction, COPD Assessment Test score and the Modified British Medical Research Council dyspena score. So, we believe that the subjective and objective sleep quality of patients with high risk of acute exacerbations of COPD was poor, and the sleep quality of patients with overlap syndrome was worse than that of patients with COPD alone.

A good high-quality of sleep and it's have an effect on in daily existence of both the healthful and sick character turns into one of the most important cognizance of problem. Aims: The study aimed to assess the Quality of Sleep and Perceived Sleep Distractors among patients. Methods: Non-Experimental descriptive research design was conducted among 135 patients through convenient sampling technique. Modied Sleep quality Scale and Structured Perceived Sleep Distractors Perfoma was used. Results: Showed (27.4%) of the patients had poor quality of sleep, most of the patients (47.4%) were having fair quality of sleep. Most of the patients (52.6%) were having severe distractions while sleeping, less than half (44.4%) were having moderate level of distractions while sleeping only (3.0%) perceived very severe distraction during hospital stay. There was a moderate positive relationship between Quality of Sleep and Perceived Sleep Distractors NS Score(r=0.113, p=0.19 ). Further the results also indicated that quality of sleep is only associated with Patient admitted in 2 2 (department) (χ = 30.652, p=0.01) whereas perceived sleep distractors is associated with Education status (χ = 17.280, 2 2 p=0.02), Duration of Hospitalization (χ = 45.425, p=0.00), Patient admitted in (department) (χ = 28.066, p=0.03).Conclusion: The study concludes that there is a need to identify factors responsible that hinders good quality sleep among patients admitted in hospital as well as the sleep quality can be enhanced by decreasing the sleep distractors and thus it can be helpful in the early recovery of the patients

Occupational exposure to microwave radiation (MWR) has become an inevi-table part of life. Therefore, it is essential to assess the MWR effect on hu-man health. In this study, we examined the non-thermal effect of MWR from base transceiver station (BTS) on humans' sleep quality. Total 1150 partici-pants of different zones based on distance from BTS (145 from inter-tower/zone A; 256 from 0-150m/zone B; 241 from 150-300m/zone C, 381 from 300-500m/zone D), and 127 controls from the area without BTS installations were included. We recorded the electric field strength at the subject’s resi-dence using NBM-550 equipped with probe EF0-391. We assessed the sub-jects' sleep quality by administering the Pittsburgh Sleep Quality Index Ques-tionnaire. ANOVA revealed statistically significantly higher electric-field strength in zone B and zone A. Participants of all the groups exhibited a glob-al PSQI score less than the accepted median score of <5. This implies that subjects of all groups had good sleep quality. However, a more detailed anal-ysis using the Kruskal-Wallis and Mann-Whitney U tests revealed that the participants of exposed zones (except zone D), females, and residents of the 1-5y group had decreased sleep quality compared to control, males, and subjects of >5y group, respectively. From the above findings, it can be con-cluded that the MWR had little effect on the sleep quality, but it does modu-late sleep parameters within the accepted range of good sleep quality as a function of the zone, gender, and year of residence. However, extensive studies involving more BTS are desirable to validate the above conclusion.

Abstract Background and objective The extent to which adult sleep varies depending on the day of the week has not yet been systematically investigated with electroencephalography (EEG) data. Whether such effects exist and whether they are related to age, gender, and employment status was retrospectively analyzed based on data from an experimental double-blind cross-over study in which effects of electromagnetic fields of a cell phone base station on the sleep of a general rural population had been examined. Methods The sleep of 397 adults (age 45.0 ± 14.2 years, range 18–81 years; 50.9% women) from ten different rural German villages was recorded for 12 nights with ambulatory devices. Self-reported sleep quality was recorded in morning and evening protocols. Friedman tests were used for statistical analysis of the comparison between the days, and the Kruskal–Wallis and Mann–Whitney U tests were used for pairwise comparisons of independent parameters between groups. Results For the present analysis, data from 335 participants were considered. Overall, the differences between nights were small and the quality of sleep was good. Three of the five objective and all six self-rated sleep parameters differed significantly between the days of the week. While the objective and the self-estimated total sleep time were longest on Sunday nights, the qualitatively poorest values occurred on Monday nights. People who worked fulltime had the longest sleep latencies on Sunday nights. Friday nights were rated the best. Conclusion The objective and self-rated sleep quality varied relatively little in a rural adult population over the course of the week, being worst on Monday nights and best on Friday nights.

This study evaluated the sleep quality of athletes in normobaric hypoxia at a simulated altitude of 2,000 m. Eight male athletes slept in normoxic condition (NC) and hypoxic conditions equivalent to those at 2,000-m altitude (HC). Polysomnographic recordings of sleep included the electroencephalogram (EEG), electrooculogram, chin surface electromyogram, and electrocardiogram. Thoracic and abdominal motion, nasal and oral airflow, and arterial blood oxygen saturation (SaO2) were also recorded. Standard visual sleep stage scoring and fast Fourier transformation analyses of the EEG were performed on 30-s epochs. Subjective sleepiness and urinary catecholamines were also monitored. Mean SaO2 decreased and respiratory disturbances increased with HC. The increase in respiratory disturbances was significant, but the increase was small and subclinical. The duration of slow-wave sleep (stage 3 and 4) and total delta power (<3 Hz) of the all-night non-rapid eye movement sleep EEG decreased for HC compared with NC. Subjective sleepiness and amounts of urinary catecholamines did not differ between the conditions. These results indicate that acute exposure to normobaric hypoxia equivalent to that at 2,000-m altitude decreased slow-wave sleep in athletes, but it did not change subjective sleepiness or amounts of urinary catecholamines.

Abstract Background Inflammatory bowel disease (IBD) is associated with a reduced quality of life. Minority patients with IBD specifically report more impairing symptoms compared with nonminority patients. Sleep quality, a key component of quality of life, is significantly compromised in minority patients compared with nonminority patients. Nevertheless, subjective and objective sleep assessments in minority patients with IBD have not explicitly been assessed. The purpose of this prospective cohort study is to assess and compare objective sleep parameters utilizing wrist actigraphy between minority and nonminority IBD patients. Methods In this institutional review board approved study, 74 patients with IBD were recruited and stratified into 2 cohorts by self-identification: white nonminority patients and minority patients. Patients in the minority cohort included black and Hispanic individuals (black and nonblack). Exclusion criteria included significant comorbidity, a history of an underlying sleep disorder, or patients who did not self-identify into categorized cohorts. Sleep was measured not only through wrist-based actigraphy but also with sleep surveys. Sleep parameters were compared between minority and nonminority cohorts. Regression analyses were performed to assess for factors independently associated with parameters of poor sleep quality. Results Sixty-four patients (86.4%) were included in the final analysis. Thirty-one individuals (48.4%) were categorized into the nonminority cohort, and 33 (51.6%) patients were in the minority cohort. A significantly higher number of minority patients had poorer sleep efficiency and fragmented sleep compared with nonminority patients (90.9% vs 67.7%; P = 0.03 and 87.8% vs 61.3%; P = 0.02). In the adjusted analysis, minority status was independently associated with poor sleep efficiency (odds ratio = 6.41; 95% confidence interval, 1.48-28.17; P = 0.0139) and fragmented sleep (odds ratio = 4.98; 95% confidence interval, 1.09-22.89; P = 0.0389). Conclusions Minority patients with IBD were shown to have poorer objective measures of sleep as assessed through wrist actigraphy compared to nonminority patients. Cultural competency in the care of minority patients with IBD, specifically focusing on the management of psychosocial issues, is needed to address these disparities in sleep. The inclusion of minority patients with IBD in studies investigating sleep and other psychosocial issues are warranted not only to assess potential disparities in disease course but also to determine the etiologies of poor sleep in minority patients with IBD.

Introduction: the COVID-19 pandemic incited unprecedented global restrictions on society’s behavior. Home detachment and isolation measures applied during the COVID-19 pandemic can result in problems with sleep quality. It is an important measure to reduce the risk of infection from the COVID-19 outbreak. Objective: to investigate the existence of a difference between the quality of sleep before and during the home distance imposed by the Covid-19 pandemic. Methods: cross-sectional web-based survey was sent using different conventional social media to collect data from the study population. The evaluated group was composed of 124 subjects, 57 of whom were male and 67 were female from the city of Rio Branco / AC. For this study, the Pittsburgh Sleep Quality Index questionnaire (PSQI-BR) and a socio-demographic questionnaire were used. The volunteers received a link along with the description and purpose of the study. Finally, data analysis was performed using SPSS 22.0 software. Results: sleep quality worsened significantly during home distance in four sleep components (subjective sleep quality, sleep latency, sleep drowsiness and overall PSQI score). During social distance, poor sleep was greater among respondents (OR = 5.68; 95% CI = 1.80–17.82; p = 0.70). Conclusion: the results indicated that there was a significant difference between the quality of sleep before and during home detachment and sleep disturbance and the subjective quality of sleep before and during the period of the outbreak of COVID-19 were the components that most worsened in the state of sleep

Quality Sleep

Background: Quality sleep is needed by breast cancer patients in order to maintain good physical condition and immune system. Nurses have a role as educators who provide health education. Health education that can be given is non-pharmacological therapy, namely music therapy and PMR to improve sleep quality. Health education for patients is felt to be very important considering that patients are not always hospitalized so that it is hoped that with health education, patients can carry out care independently at home.Methods: The way of implementing community service activities is carried out by exposing non-pharmacological therapies with nurses who are in charge of the chemotherapy room. After being given the material, the selected nurse will apply the therapy to the patient in order to improve the quality of sleep for breast cancer patients who are given chemotherapy.Results: The provision of music therapy and PMR had a positive effect on breast cancer patients undergoing chemotherapy. Most of the patients involved in this service reported an improvement in the quality of sleep.Discussion: Good quality sleep is needed by breast cancer patients to regenerate and repair body cells. Music therapy combined with PMR is effective in reducing physical arousal activity which results in decreased muscle tone so that sleep quality can be fulfilled.
