Sleep Hygiene in the context of Methods

This topic is part of our "Methods" world. There you'll find methodology, evidence and the highest-impact levers — plus the order in which they sensibly build on each other.

Top studies on Sleep Hygiene

Ranked by influential-citation count and publication year.

  1. "Sleep disparity" in the population: poor sleep quality is strongly associated with poverty and ethnicity.

    BMC public health2010n=10,100105 influential citations

    <h4>Background</h4>Little is known about the social determinants of sleep attainment. This study examines the relationship of race/ethnicity, socio-economic status (SES) and other factors upon sleep quality.<h4>Methods</h4>A…

  2. Day-to-day associations between pain intensity and sleep outcomes in an adult chronic musculoskeletal pain population: A systematic review.

    Sleep Med Rev2025n=101Systematic Review83 influential citations

    <h4>Background</h4>In individuals with chronic musculoskeletal pain, a reciprocal relationship between sleep and pain across short and long-term evaluations exists. Sleep influences pain levels, while the level of pain also impairs sleep.…

  3. The best approaches and doses of exercise for improving sleep quality: a network meta-analysis and dose-response relationship study.

    BMC Public Health2025n=7,276Meta-Analysis63 influential citations

    <h4>Background</h4>Poor sleep quality not only diminishes people's quality of life and work efficiency but is also closely associated with various diseases. A reasonable exercise regimen can improve sleep quality to some extent, but there…

  4. Sleep quality and duration and frailty in older adults: a systematic review.

    Front Public Health2025n=58,447systematic63 influential citations

    INTRODUCTION: Sleep problems and frailty are associated with adverse health outcomes in older adults, including mortality, and constitute a major public health challenge. OBJECTIVE: This study investigated the association between sleep…

  5. Effects of vagus nerve stimulation on the quality of sleep and sleep apnea in patients with drug-resistant epilepsy: A systematic review.

    Epilepsia2024n=12Systematic Review61 influential citations

    <h4>Objective</h4>The objective was to systematically evaluate the current evidence surrounding the effect of vagus nerve stimulation (VNS) on quality of sleep and obstructive sleep apnea (OSA) among patients with…

  6. Sleep and the Mediterranean diet: A systematic review and meta-analysis.

    Sleep Med Rev2025n=63Meta-Analysis59 influential citations

    We conducted the current systematic review and meta-analysis to critically review and synthesize available evidence regarding the association between sleep duration, sleep quality, and chronotype with the Mediterranean diet (MedDiet) among…

    Finding: Sufficient sleep duration was associated with increased odds of high Mediterranean diet scores compared with insufficient sleep duration.

  7. Effects of sleep hygiene education for insomnia: A systematic review and meta-analysis.

    Sleep Med Rev2025n=424Meta-Analysis56 influential citations

    Sleep hygiene education (SHE) as a single therapy for insomnia still lacks sufficient evidence. This study aimed to quantify the effects of SHE on insomnia treatment. A literature search was conducted on seven databases from inception up…

  8. Relationships among sleep quality, anxiety, and depression among Chinese nurses: A network analysis.

    J Affect Disord2025n=711meta49 influential citations

    BACKGROUND: This study aimed to elucidate the symptom-symptom interactions of sleep quality, depression, and anxiety in Chinese nurses and to compare a multimorbidity group, a comorbidity group, and a healthy group via a network model.…

    Finding: Depressed affect was the most central symptom in the entire sample and in the multimorbidity group.

  9. Multidimensional sleep health and diabetic retinopathy: Systematic review and meta-analysis.

    Sleep Med Rev2024n=2,419,768meta46 influential citations

    Diabetic retinopathy (DR) is one of the most prevalent microvascular diabetic complications. Poor sleep health and obstructive sleep apnea (OSA) are risk factors for diabetes and poor glycemic control. Recent studies have suggested…

  10. Impact of physical therapy techniques and common interventions on sleep quality in patients with chronic pain: A systematic review.

    Sleep Med Rev2024n=17Systematic Review35 influential citations

    This systematic review aims to find effectful healthcare strategies, with special focus on drug-free interventions and physical therapy, as part of the treatment for sleep in patients with chronic musculoskeletal pain. Data search was…

Frequently asked

What dosage was studied?
• Non-pharmacological interventions (cognitive behavioural therapy, relaxation techniques, exercise, massage, acupressure, aromatherapy, music, eye mask, earplugs) (Varied by intervention; not reported uniformly) • Day-to-day assessment of sleep variables and pain intensity (Not reported)
Are there safety considerations for Sleep Hygiene?
• Not reported • No adverse events were reported; this was a systematic review of observational studies. • VNS implantation was associated with increased OSA or higher sleep apnea severity indices. • Patients developing sleep apnea after VNS may need parameter adjustment or monitoring.
