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.

Brain health. Promising prebiotics and probiotics combination

According to new research, the bacteria in our gut, known as gut microbiota, play an important role in brain injury and healing after a stroke. Taking particular types of prebiotics and probiotics can help with brain injury, inflammation, gut bacteria imbalances, and intestinal health. However, we still don't know whether prebiotics, probiotics, or synbiotics (a combination of both) perform best for particular conditions, or how they operate. In this study, scientists tested a new synbiotic formulation containing multiple strains of probiotics Lactobacillus reuteri UBLRu-87 Lactobacillus plantarum UBLP-40 Lactobacillus rhamnosus UBLR-58 Lactobacillus salivarius UBLS-22 Bifidobacterium breve UBBr-01 and prebiotic fructooligosaccharides (FOS) FOS are extracted from the blue agave plant and fruits and vegetables such as bananas, onions, chicory root, garlic, asparagus, jícama, and leeks. Some grains and cereals, such as wheat and barley, also contain FOS. The Jerusalem artichoke and ...

Light Therapy holds promise as a treatment for Alzheimer's Disease

A new article, conducted by Lili Zang and colleagues from Weifang Medical University School of Nursing in Shandong Province, China, discusses a meta-analysis of 15 high-quality trials that investigated the impact of light therapy on individuals with Alzheimer’s disease (AD). The meta-analysis included 598 patients with mild to moderate Alzheimer’s disease, and it covered 15 randomized controlled trials conducted in seven different countries. Those trials were published between 2005 and 2022. Sleep Improvement Light therapy led to significant improvements in several sleep measures. It notably enhanced sleep efficiency, increased interdaily stability, and reduced intradaily variability, all of which are indicators of better sleep quality. Light therapy was associated with a reduction in agitation, depression, and caregiver burden among individuals with Alzheimer’s disease. A significant advantage over usual care was shown in reducing the severity of psychobehavioral symptoms, as assessed...
