Stress, Coping, and Sleep Health Study
Background: Poor sleep is common among refugee groups worldwide. It can lead to an increased risk of heart disease, diabetes, cancer, and premature death. It can also worsen mental health disorders. Researchers have studied the mental health issues among refugees from Bhutan in the United States. Now they want to understand more about how difficulty sleeping may relate to their other health outcomes. Objective: To learn how the social and environmental conditions Bhutanese refugees affect their sleep health and health outcomes. Eligibility: Refugees aged 18 years and older of Bhutanese-Nepali or Bhutanese American descent. The participants must live in central Ohio. Also needed are people aged 18 years and older who interact with Bhutanese refugees in this region. Design: Participants will participate in a focus group discussion. The group will have 8 to 10 participants. It will last 60 to 90 minutes. They will talk about their experiences as a refugee and their sleep health. Topics may include adjusting to a new culture; access to housing and health care; and experiences with differential treatment by members inside and outside of their group. The study team will audio record the discussion. They will not share the recording with anyone. Participants will complete a short questionnaire. They will answer questions about their age, sex, language preferences, and how long they have lived in the United States. Participants who are not refugees will take part in a virtual interview led by a member of the study team. Participants will share their experiences with adapting to a new culture, differential treatment, and other factors have affected refugees sleep. The interview will take about 1 hour.

Multidimensional Sleep Health Intervention for Couples
The goal of this pilot dyadic study is to adapt a multidimensional sleep health (MDSH) intervention, previously disseminated at the individual level, for relationship partners, determine whether it improves sleep health and aspects of cardiometabolic health, and understand the role of dyadic dynamics in intervention effects. Can a dyadic MDSH intervention improve sleep health and blood pressure (primary outcomes) in relationship partners? Can a dyadic MDSH intervention improve anthropometric markers of adiposity, psychosocial indicators, stress, dyadic adjustment and coping, self-rated health (secondary outcomes) in relationship partners? As this is a single-arm study, there is no control group. All relationship partners will complete a three-tier screening process, attend two in-person visits to receive intervention materials, have blood pressure measured and sleep data collected using in-office and out-of-office monitors, participate in weekly check-in phone calls with research staff over the 8 weeks to support adherence and complete a voluntary follow-up phone call at 16 weeks to provide additional sleep health information. The multidimensional sleep health promotion intervention is based on evidence-based sleep hygiene education and established behavior change techniques and includes: report-back of sleep health profiles, S.M.A.R.T (specific, measurable, attainable, realistic, and timely) goal-setting and establishing a sleep health plan with a fixed sleep schedule, sleep health coaching and dyadic action planning, self-monitoring, virtual sleep hygiene education, motivational feedback, and addressing light and noise in the sleep environment. Mixed methods will be used to understand implementation metrics, processes, and outcomes to establish the successful completion and future expansion of the intervention within this context.

Studying Childhood-onset Behavioral, Psychiatric, and Developmental Disorders
Background: \- Many psychiatric, behavioral, and developmental disorders are genetic. This means that they tend to run in families. Some begin in childhood, while others do not appear until adulthood. Researchers want to look at people of all ages who have these disorders that started in childhood. They will also look at relatives of people with these disorders. This information will allow doctors to learn more about childhood behavioral problems and how they are inherited. It may also help doctors treat those disorders. Objectives: \- To study the onset and treatment of childhood behavioral, psychiatric, and developmental disorders. Eligibility: * Individuals of any age who have a psychiatric, autism spectrum, or developmental disorder, or other behavioral problems. * Family members of individuals with the above disorders. This group may include parents, grandparents, siblings, aunts/uncles, cousins, and children. Design: \- Participants will be screened with a medical history and physical exam. They may have a psychiatric history with tests of thinking, judgment, and behavior. Brain imaging scans may be performed to look at brain function.

Cannabidiol and Older Adult Cannabis Users
Cannabis use increased 10 fold among adults over the age of 65 between 2014 and 2016 but very little data exists on the extent of their harmful effects on health and behavior. The overarching goal of this project is to test a novel harm reduction strategy in which older individuals who seek to use cannabis for pain, anxiety or mood problems (depression/anxiety) will be randomly assigned to one of three conditions in an 8 week randomized controlled trial: hemp-derived CBD+THC, hemp-derived CBD-THC, or placebo. This work has the ability to directly inform individual choices regarding the use of cannabis products among older adults, and direct policy decisions regulating cannabis formulations on the legal market.

sCAVA - Sleep Assessment Using the CAVA Device
Clinical investigation of a medical device (CAVA) for recording eye movements. Forty volunteers will sleep in a specially designed sleep lab for one or two nights, depending on whether they are enrolled onto phase 1 (two nights) or phase 2 (one night) of the study. Each volunteer will wear the CAVA device along with a Polysomnography (PSG) device, which is the gold standard for monitoring sleep. The twenty participants in phase 2 will simultaneously wear a commercially available consumer device for monitoring sleep. The eye movement data captured using CAVA will be processed by novel computer algorithms to classify the sleep stages in the data into Rapid Eye Movement (REM), non-REM and awake. The results will be compared with the ground-truth from the gold standard, and also compared to the results from the commercially available device. The aim of the study is to determine whether CAVA could be a viable and competitive home-monitoring device for analysing sleep.

I-SLEPT: Integrated Sleep and Life Engagement Program for Transitions
Sleep is essential to functional recovery in rehabilitation settings; however, sleep is likely to be disrupted during rehabilitation admissions. Adverse effects of these disruptions do not subside after discharge, leading to additional consequences such as poor physical function. Veterans are particularly impacted by poor sleep and medical complexities that can lead to injuries requiring rehabilitative care to support their recovery. This may be more apparent in older Veteran populations. After discharge, Veterans must re-acclimate to their home environment while facing potential changes in their sleep, life engagement (e.g., pleasant activities, physical function), and health. This study will create the I-SLEPT (Integrated Sleep and Life Engagement Program for Transitions) intervention, which will support Veterans by stabilizing their sleep and by maximizing participation in meaningful activities during a critical and vulnerable period of recovery.

Hospital Environmental Exposure
There is an increasing body of evidence that human health is affected by environmental factors such as air quality, noise and light. This applies to both indoor and outdoor environments. While there have been several studies looking at homes, offices and work environments, hospital environments are still poorly characterised. Indoor hospital environments are complex, and patients with various health conditions can spend extended periods of time in wards. A number of studies have reported an association of air pollution exposure and a disturbance to sleep. A lack of sleep, or poor and disrupted sleep can impact health. Disturbed sleep therefore can impact a patient's recovery in hospital wards. In addition to the exposure to air pollutants, noise and light levels within the hospital environment can also have an impact on patient health. Inadequate, or a disrupted light and dark cycles can impact the circadian rhythm of the human body, responsible for the sleep cycle. In this study, the investigators aim to characterise these exposures and address the impact of these exposures on the patient sleep. Given the links between sleep and the environmental conditions.

Aerobic Exercise: A Potential Rescue From the Negative Ramifications of Poor Sleep
The goal of this interventional study is to differentiate the effects of an acute partial sleep deprivation intervention on markers of cardiovascular health, cardio-autonomic function, physical and cognitive performance, as well as overall wellbeing in active vs sedentary individuals. The main aims of the project are: * To differentiate the effects of partial sleep deprivation on central hemodynamics (i.e., central blood pressure and arterial stiffness) in active vs sedentary individuals. * To differentiate the effects of partial sleep deprivation on physical (i.e., handgrip strength and reactive strength index) and cognitive performance (i.e., reaction time and impulse control) in active vs sedentary individuals. * To differentiate the effects of partial sleep deprivation on overall wellbeing (i.e., cardio-autonomic function, inflammation levels, and psychological mood states) in active vs sedentary individuals. Participants will be divided into two groups based on aerobic activity level - active or sedentary - and assessed for markers of cardiovascular health, cardio-autonomic function, physical and cognitive performance, as well as overall wellbeing before and after three days of normal sleep and three days of partially deprived sleep (i.e., 30% reduction in total time in bed).

Transdiagnostic Sleep and Circadian Treatment for Autistic Adolescents
Sleep and circadian problems are associated with deleterious social, emotional, and cognitive outcomes, yet are modifiable. This prospective study will adapt and optimize an empirically supported behavioral intervention that addresses common sleep and circadian problems of autistic adolescents, who are at increased risk for mental health disorders, using a transdiagnostic approach. The knowledge gained from this study will help to address a critical need for accessible transdiagnostic sleep interventions for autistic adolescents, who experience a broad range of sleep and circadian problems at high rates and often lack access to specialty care treatment.

Transdiagnostic Sleep and Circadian Intervention + Bright Light in Adolescents With Elevated Depression (TranS-C+BL)
The goal of this clinical trial is to adapt a sleep intervention for individuals representative of all demographic groups, including those who are at the highest risk for suicidal behavior. Sleep difficulties are a promising target for youth with suicidal thoughts and behavior to focus on as a prevention measure. We aim to increase intervention acceptability and impact by adapting it for the adolescent populations at highest risk for suicidal thoughts and behavior. The research project will compare Transdiagnostic Sleep and Circadian Intervention (TranS-C), an evidence based, modularized intervention that targets a range of sleep difficulties to a treatment as usual or control condition including providing weekly sleep feedback reports from data entered into a daily sleep diary and from wearing a sleep sensing, actigraphy watch. Participants in both conditions (TranS-C vs. Sleep Feedback) will wear an actigraphy sleep watch that monitors sleep, and complete daily sleep diaries via smartphone or email. Participants in the TranS-C condition will also wear bright light (BL) and blue blocking glasses each day as well as attend weekly or biweekly sessions with a Sleep Therapist. The sleep therapist will review sleep feedback during sessions.

Project REST: Regulation of Eating and Sleep Topography
Overweight/obesity and inadequate sleep are prevalent, and frequently co-occurring, health risks among children, both of which are associated with serious medical and psychosocial health complications including risk for cardiovascular disease. Although the investigator's data suggest that disrupted or shortened sleep may be causally associated with increased energy intake and weight gain in children, and with self-regulation and neural response to food cues in adults, understanding of mechanisms involved in the sleep/eating association is incomplete, thereby impeding development of targeted, optimally timed intervention strategies. The proposed mechanistic clinical trial aims to assess the effects of an experimental sleep manipulation on eating-related self-regulation and its neural substrates, and on real-world eating behavior, among children with overweight/obesity, which will help guide research efforts towards the refinement of prevention and intervention strategies targeting sleep and its eating-related correlates to curb weight gain throughout development.

Support Your Heart, Phase 1
This is a pilot feasibility study designed to establish the feasibility and acceptability of the "Support Your Heart" (SYH) study's phone-based protocols regarding AHA's LE8, social isolation, loneliness, and stress. The age range for this intervention is 18-39, which is intended to reflect the transitional life period from adolescence to adulthood. Participants must also display at least two LE8 risk factors for cardiovascular disease (e.g., not enough sleep or physical activity; tobacco/nicotine product use; elevated body mass index; high cholesterol, high blood pressure, elevated HbA1c , and/or poor diet). Participants will receive weekly calls (averaging around 20-30 minutes each) from a SYH health coach in order to review key concepts, give personalized progress, and provide consistent feedback over the course of 12 weeks. SYH staff will measure improvement in AHA metrics as well as participant burden, acceptability, satisfaction, adherence, and retention. This research has the potential to create substantial public health impact by addressing cardiovascular health, social isolation, loneliness, and stress, all of which represent significant burdens to individual health.

Improving Sleep Health and Circadian Timing to Support Cardiometabolic Health in Adolescents
Many teenagers get too little and late timed sleep. High body weight and diabetes are increasing in teenagers as well. This study plans to learn more about whether improving sleep habits can help improve how the body regulates blood sugar and energy use in teenagers who have higher body weight. To answer this question, the investigators plan to enroll teenagers who get \<7 hours of sleep on school nights and measure changes in blood sugars and energy use after two weeks of typical sleep (sleeping on their normal school schedule) and two weeks of a sleep intervention that includes spending longer time in bed at night, melatonin, and morning light.

Sleep and Performance
This research is being done to apply new, contrast-free MRI (Magnetic Resonance Imaging) methods to understand the brain's waste clearance system (the "glymphatic" system) in younger adults. The Investigators hope the study will show how the different brain regions are involved in maintaining memories and how poor sleep affects these regions and our ability to remember. The Investigators will test whether the Wireless Interface Sensor Pod (WISP) improves brain function after poor sleep. The WISP is a headband that combines tracking brain waves and transcranial electrical stimulation (TES) to monitor and improve slow wave sleep and glymphatic clearance. IParticipants will be asked to: * Complete 4 in-person study visits (1 per week) over 4 weeks at the Diagnostic Imaging Sciences Center (DISC), located at the University of Washington Medical Center at Montlake, Seattle. Each visit will last 2 hours and includes a 1 hour MRI and 1 hour of cognitive testing. * Complete a daily journal about sleep, daily habits, etc. * The night before each of the four study visits, participants will sleep while wearing the WISP headband. * For two of these nights, participants will sleep only 3 hours prior to normal time of awakening. The WISP will deliver a small electrical current for one night and not for the other night, but participants will not know which. * For the other two nights, participants will follow a normal sleep schedule. The WISP will deliver a small electrical current for one night and not for the other night, but participants will not know which.
