Me sube la vasopresina. Efectos que produce el amor.

en la sangre se generan las hormonas oxitocina y vasopresina, que estimulan la formación del contacto emocional entre los enamorados.

RT | Medicina y Salud | 11 de febrero 2010 | 01:33. Científicos estadounidenses pudieron confirmar que el comienzo del enamoramiento hace casi el mismo efecto en el organismo humano que una dosis de cocaína.

El psícologo Arthur Aron de Nueva York hizo estos sorprendentes descubrimientos al someter a los enamorados a una tomografía del cerebro. Cuando a los participantes del experimento les mostraban fotos de la persona objeto de su enamoramiento, la zona de su cerebro que responde a la motivación se saturaba de dopamina, una sustancia que aparece en la sangre al sentirse sensaciones agradables como al practicar el sexo, comer chocolate o consumir drogas.

Luego, en la sangre se generan las hormonas oxitocina y vasopresina, que estimulan la formación del contacto emocional entre los enamorados. La oxcitocina aparece en la sangre en los momentos del contacto íntimo entre los sujetos: puede ser una mirada a los ojos durante un largo tiempo, abrazos o el acto sexual.

Tradicionalmente se creía que en la mayoría de las parejas el amor apasionado, con el paso del tiempo, se transforma en algo más parecido al amor fraternal. Aunque, recientemente, una científica de la Universidad de Santa Bárbara estudió los resultados de la tomografía de unos esposos que afirmaron sentirse enamorados igual que hace 20 años y descubrió reacciones semejantes a las de los cerebros de los recién enamorados.

Los científicos aconsejan a las parejas que se dediquen juntos a actividades agradables, las que estimulan la producción de la dopamina. Por ejemplo, ir al teatro o al hipódromo o estudiar algo nuevo. Los especialistas señalan que los que se sienten felices en el matrimonio, tienen una vida más larga y un sistema unmunológico más fuerte.

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
