Perfume de mujer que mueve la testosterona de los hombres.

ScienceDaily (18 de enero de 2010), Las mujeres en todo el mundo destinan a miles de millones de dólares cada año en exóticos perfumes y lociones con la esperanza de atraer a un compañero. Sin embargo, de acuerdo con un nuevo estudio en Psychological Science, un diario de la Asociación para la Ciencia Psicológica, ir “al natural” puede ser la mejor forma de capturar la atención de parejas potenciales.
Hay olores que se saben críticos para hábitos de apareamiento animal: los estudios en animales han demostrado que los niveles de testosterona masculina están influenciados por el olor de las señales emitidas por las mujeres, especialmente cuando están ovulando (es decir, cuando son las más fértiles).  Los psicólogos  Saul L. Miller y Jon K. Maner de la Universidad del estado de Florida de quisieron  ver si una respuesta similar ocurre en los seres humanos. En dos estudios, las mujeres usaban remeras  tres noches seguidas durante distintas fases de su ciclo menstrual. Voluntarios masculinos olía a una de las camisetas que habían sido llevadas por un participante femenino. Además, algunos de los voluntarios masculinos olían camisetas de control que no habían sido usados. Se recolectaron muestras de saliva para el análisis de testosterona antes y después de que los hombres olían las camisetas. Los resultados revelan que los hombres que olían camisetas de mujeres que ovulaban tenían niveles más altos de testosterona que los hombres que olían camisetas usadas por  mujeres que no ovulaban o camisetas de control. Además, después de oler las camisetas, los hombres clasificaron los olores según lo placenteros que resultaran  y evaluaron a las camisetas usadas por las mujeres que ovulaban  como las de más agradable olor. Los autores señalan que "la presente investigación es la primera en proporcionar evidencia directa que señales olfativas de la ovulación femenina influyen en las respuestas biológicas en los hombres". En otras palabras, este estudio sugiere que los niveles de testosterona pueden ser sensibles a olores que indican cuando una mujer es fértil. Los autores llegan a la conclusión de que esta respuesta biológica puede promover respuestas relacionadas con el apareamiento por parte de los hombres.

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
