"Las personas que mostraron altos niveles de ira y ansiedad presentaron un mayor aumento del marcador indicativo, que los que se mantuvieron relativamente en calma", explica la directora del estudio, Judith Carroll.


(EUROPA PRESS) 18/02/2011La respuesta emocional de las personas a situaciones difíciles puede predecir cómo su cuerpo responde al estrés, según un estudio de la Universidad de Pittsburgh (Estados Unidos), que explicaría por qué algunas personas que acumulan muchas preocupaciones, presentan problemas crónicos de ansiedad.

Los autores del trabajo, que publica 'Brain, Behavior, and Immunity', pidieron a individuos sanos de mediana edad que completasen un discurso en el laboratorio delante de la cámara de vídeo y de un panel de jueces. Después, debían verificar las emociones que habían experimentado.

En este sentido, subrayan que la mayoría de las personas muestran un incremento en la frecuencia cardíaca y en la presión arterial cuando completan una tarea estresante y también aumenta el nivel de un marcador de circulación conocido como interleuquina-6.

"Las personas que mostraron altos niveles de ira y ansiedad presentaron un mayor aumento del marcador indicativo, que los que se mantuvieron relativamente en calma", explica la directora del estudio, Judith Carroll.

"Nuestro estudio muestra que las personas que tienen los mayores incrementos en este indicador son los que muestran la mayor respuestas emocionales a las tareas difíciles", afirma Carroll.

Por su parte, otra de las autoras del estudio, Anna Marsland, explica que los resultados plantean la posibilidad de que las personas que se enojan o tienen mucha ansiedad cuando se enfrenta a retos que no tienen excesiva importancia en sus vidas son propensas a un aumento de estos marcadores.

"Con el tiempo, esto puede hacer que estos individuos emocionalmente reactivos sean más vulnerables a las enfermedades inflamatorias, como la enfermedad cardiovascular", asegura la experta.

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
