El sueño, importante en la enfermedad crónica

Un estudio encuentra que entre 7 y 8 horas es óptimo para los adultos, pero que el exceso o la falta aumentan los riesgos de salud

Robert Preidt Traducido del inglés: Jueves, 15 de julio, 2010 MIÉRCOLES, 14 de julio (HealthDay News/HolaDoctor) -- El exceso o la falta de sueño podrían aumentar el riesgo de desarrollar afecciones crónicas como obesidad, diabetes, hipertensión y enfermedad cardiovascular, según una investigación.
"Entre siete y ocho horas de sueño por noche parece ser la cantidad ideal para maximizar los beneficios de salud y minimizar los riesgos de enfermedad cardiometabólica", aseguró el autor colíder Orfeu Buxton, investigador de la división de medicina del sueño del Hospital Brigham and Women's (BWH) en Boston, en un comunicado de prensa conjunto del BWH y la Universidad Estatal de San Diego (SDSU).
Buxton y colegas analizaron datos de 56,507 adultos estadounidenses que participaron en la Encuesta nacional de entrevista de salud y encontraron que, en comparación con dormir entre siete y ocho horas por noche, dormir menos de seis horas y más de nueve horas se asociaba con un mayor riesgo de afecciones crónicas como la obesidad, la diabetes y la hipertensión.
El estudio fue publicado en una edición avanzada en línea de la próxima edición impresa de la revista Social Science & Medicine.
"La obesidad, la diabetes y la enfermedad cardiovascular están entre las principales causas de mortalidad en los Estados Unidos", advirtió en el comunicado de prensa el autor colíder del estudio Enrico Marcelli, profesor asociado del departamento de sociología y del Instituto de estudios conductuales y de salud comunitaria de la SDSU. "Estos hallazgos enfatizan el importante papel que el sueño desempeña en la salud de los estadounidenses, e indican que el sueño podría tener una mayor influencia sobre estas enfermedades crónicas que la dieta o el ejercicio".

Nordic Walking Benefits, ADHD and Diet, Supplements and Cancer, Sources of Fiber

A Better Way To Walk: Nordic Walking Improves Quality of Life, Depression, and Functional Capacity SciTechDaily Reference: “Sustained Effects of Different Exercise Modalities on Physical and Mental Health in Patients With Coronary Artery Disease: A Randomized ... Dietary Interventions for ADHD: Emerging Research and Considerations There has been increasing interest in the role that diet and supplements play in the treatment of attention-deficit/hyperactivity disorder (ADHD) symptoms, from patients and researchers alike. Diet is an important treatment approach to consider, as it is a lifestyle change rather than a medication. Additionally, at least 10% to 30% of children with ADHD are non-responsive to, or experience adverse effects from, ADHD medications.1 A dietary approach to ADHD can be complementary to a conventional pharmacological approach, giving patients and their families more options toward a personalized treatment plan. This article will examine current research about di

More People Are Microdosing for Mental Health. But Does It Work?

By Dana G Smith. Joseph started microdosing psychedelics five years ago to try to improve his mental health. “I was just kind of in this depression, in this rut,” he said. “I was unhappy and angry and agitated all the time, and it went against the way that I saw myself.” Depression and anxiety run in Joseph’s family, and he’d been prescribed Prozac as a kid. But when symptoms of depression returned in his early 30s, he didn’t want to go back to a prescription drug. Joseph, an Austin-based designer (he asked to withhold his full name, citing privacy concerns surrounding mental health issues and illegal drug use), came across research from Johns Hopkins University about psilocybin, the active ingredient in hallucinogenic, or “magic,” mushrooms. In a small study, full doses of the drug helped cancer patients cope with depression and anxiety. Then he read anecdotes of Silicon Valley influencers claiming increased energy from taking tiny doses of psychedelics. So he decided to start microdo

Exploring the Link Between Circadian Rhythms, Longevity, and Wearable Data: Insights and Future Directions

A recent study in NHANES 2011–2014 explores the potential connection between disruptions in circadian rhythms, measured using wearable devices, and their impact on health outcomes and longevity. The study analyzes data from 7,297 U.S. adults collected through wearable accelerometers as a novel digital biomarker for longevity. Five distinct clusters were identified based on activity profiles: "High activity," "Low activity," "Mild circadian rhythm (CR) disruption," "Severe CR disruption," and "Very low activity." The findings reveal that young adults with extreme circadian rhythm disturbance exhibit higher white blood cell counts and accelerated biological aging. Older adults with circadian disruption are associated with increased systemic inflammation indexes, advanced biological aging, and higher all-cause mortality risk. The research underscores the importance of circadian alignment for longevity at all ages and suggests that wearable
