Filter by:Thymus vulgaris could potentially serve as a safer alternative to stimulant drugs for enhancing memory among university students. Furthermore, Thymus vulgaris may offer additional benefits in terms of reducing anxiety, depression, and improving sleep quality. However, it should be noted that the current research on the effects of orally administered Thymus vulgaris on the brain and nervous system is limited, and further studies are required to fully explore its potential advantages. Therefore, the purpose of this study is to investigate the effects of oral Thymus vulgaris on memory performance, anxiety, depression, and sleep quality in university students.
The goal of this randomized, cross-over, single-site trial followed by an exploratory third intervention is to understand how indoor lighting affects different measures of brain health in older adults living in independent living residences. This is a community based study occurring in a local senior living facility. The main question this study aims to answer is: - How does the quality of ambient indoor lighting an older adult is exposed to affect measures of brain health, such as sleep quality, physical activity, cognitive function, and social engagement? Participants will be exposed to three different indoor lighting conditions for 4 weeks each while performing the following tasks: - Wear a smartwatch throughout the study to measure sleep quality and physical activity - Wear a small, wearable light sensor to measure light exposure during waking hours - Perform cognitive assessments throughout the study to detect any changes between each of the lighting conditions - Complete self-report of surveys to assess independence, social engagement, sleep quality, and mood Results from these tasks will be compared within and between subjects to assess whether the different lighting conditions affect these different measures of brain health.
NUS1000 is a large scale freshman-year study of undergraduate sleep, well-being and learning patterns that has unique key features: (1) continuous objective multi-dimensional data gathered with passive sensing of sleep and stress over a semester, (2) utilisation of Learning Management System-based outcome data as a marker of study behaviour and academic achievement. The goal is to gather information that can be used to improve student sleep, mental wellbeing and performance.
This study will focus on the relationship between pillow and mattress factors, musculoskeletal disorders and sleep quality in office workers. Sleep is vital to physical and mental health, and poor sleep can negatively affect cognitive function and workplace performance. Office workers, who often work in sedentary jobs, are particularly prone to sleep disorders. Recognizing the factors that contribute to poor sleep in this population is crucial for developing interventions to improve sleep quality. The study used a cross-sectional design and will collect data from an appropriate sample of office workers (Approximately 600 participants). Various variables will be assessed, including sociodemographic characteristics, sleep-related factors (to be measured using the Pittsburgh Sleep Quality Index), pillow characteristics, mattress-related factors, musculoskeletal symptoms, and physical activity levels (to be measured using the International Physical Activity Questionnaire). Descriptive statistics and multiple regression analysis will be performed to analyze the data and identify factors affecting sleep quality. Fixed fixes for potential confounders and modifiers. The study aims to identify specific components of the sleep environment related to sleep disorders. The findings of this study will contribute to the understanding of how pillow and mattress factors, along with other variables, affect sleep quality in office workers. The results may provide information for interventions aimed at improving sleep habits, optimizing the sleep environment, and improving overall well-being in this population. As a result, promoting good sleep health among office workers can have positive effects on productivity, safety and overall quality of life.
Sleep is essential for health and wellness. Sleep disruption can occur due to emotional stress, advancing age, hormonal imbalance, medications, and many other causes, some of which are presently unknown. Most pharmaceutical sleep products artificially induce sedation without providing quality sleep. Thus, a need exists for safe dietary supplement to promote and support healthy sleep that will encourage restful sleep. This study will examine the efficacy, tolerance, and safety of sleep supplement as compared to a placebo.
The goal of this clinical trial is to learn about the ability of non-invasive brain stimulation during sleep to enhance people's deep sleep and its potential benefit on memory in healthy adults via home use sleep therapy device (SleepWISP). Participants will be asked to wear non-invasive and painless devices that record their brain activity during sleep. The clinical trial aims to answer the following main questions: 1. Whether the non-invasive transcranial electrical stimulation (TES) delivered by SleepWISP could provide short-term enhancement of deep sleep in a single night in the target population. 2. Whether TES delivered by SleepWISP could improve sleep quality.
Depression among older Korean Americans are rising. Mindfulness-based cognitive therapy (MBCT) is an evidence-based intervention (EBI), effective for preventing depression relapse and reducing depressive symptoms. To enhance feasibility, acceptability, and reach, a brief version of MBCT has been developed and delivered by telephone (brief MBCT-T), but has only been tested in primarily White samples. This study will test test the effect of brief MBCT-T among older Korean Americans.
The overall goal is to examine the efficacy of a circadian intervention in people with overweight and obesity and habitual short sleep duration (HSSD). Participants will undergo a randomized controlled trial, with circadian intervention and control (healthy lifestyle) groups. The circadian intervention is designed to reduce nighttime light exposure and after-dinner snack food intake. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
The goal of this randomized crossover clinical trial is to determine if habitual sleeping habits can predict endurance performance following a night of partial sleep deprivation in healthy untrained, recreationally trained, and trained cyclists (18-50 years, ~50% females). The main questions it aims to answer are: 1. Can habitual sleeping habits predict, or do different types of sleepers alter, performance outcomes following sleep deprivation? 2. Does sleep deprivation alter blood pressure, heart rate, or metabolic responses during a 20-minute time trial, and/or are these altered amongst different types of sleepers? 3. Can habitual sleeping habits predict, or do different types of sleepers alter, flow-mediated dilation following a night of normal sleep and/or sleep deprivation? - Participants will be asked to perform 4 performance tests (20-minute time trial), 2 for familiarization, and 2 testing visits (1 under normal sleep and 1 under partial sleep deprivation). - For 1 week prior to each testing visit, sleep will be tracked using an ActiGraph device. - During each testing visit, and prior to the performance test, the vascular function of the superficial femoral artery will be assessed using a flow-mediated dilation technique. The investigators hypothesize that habitual early sleepers, poor sleepers, those with greater variability in sleep duration, and females will show the greatest impairments in performance and flow-mediated dilation following partial sleep deprivation.
The GHK intervention was developed according to the United Kingdom Medical Research Council's framework for developing and evaluating complex interventions. A pilot- and feasibility study was conducted during December 2022-April 2023, and the intervention was subsequently adapted and adjusted. The GHK main trial is a two-school-year cluster-randomized school- and community trial designed to investigate the effect of the multi-setting, multi-component GHK intervention program on weight development, health and wellbeing in Danish children aged 6-11 years. The trial will include 24 schools in Denmark (12 intervention and 12 control). The primary aim of the cluster-randomized trial is to investigate whether the GHK intervention program can promote healthy body composition as measured by fat mass (FM) in the intervention group compared with the control group. We hypothesize that the intervention will result in less FM gain in the intervention group compared with the control group over the two school-year study period.
