Un estudio dice que la felicidad ayuda al corazón

" Si uno no es feliz por naturaleza, trate de actuar como si lo fuera", dijo la doctora Karina Davidson, del Centro Médico de Columbia, autora principal del trabajo. "Podría ser bueno para el corazón".
17 de febrero de 2010, 07:01 PM LONDRES (AP) - Se ha reiterado hasta el cansancio: para evitar un ataque cardíaco, hay que dejar el cigarrillo, comer alimentos sanos y hacer ejercicio. Según un estudio nuevo, también es útil ser feliz, así que quien sea gruñón por naturaleza, que trate de ser alegre.

Los investigadores de la Universidad de Columbia evaluaron los niveles de felicidad de más de 1.700 adultos en Canadá sin problemas cardíacos en 1995. Diez años después examinaron a los 145 participantes que tenían problemas cardíacos y hallaron que a mayor felicidad, menor probabilidad de padecerlos.

El estudio aparece el jueves en la edición electrónica del European Heart Journal.

"Si uno no es feliz por naturaleza, trate de actuar como si lo fuera", dijo la doctora Karina Davidson, del Centro Médico de Columbia, autora principal del trabajo. "Podría ser bueno para el corazón".

Davidson y sus colegas usaron una escala de cinco puntos para medir la felicidad. Luego la ajustaron estadísticamente por factores tales como edad, género y tabaquismo.

Por cada punto en la escala de la felicidad, disminuía en un 22% la probabilidad de padecer un problema cardíaco. El estudio fue financiado por los Institutos Nacionales de Salud del gobierno estadounidense y otras instituciones.

Según Davidson, las personas felices suelen llevar una vida más sana.

Podría existir un rasgo genético desconocido que predispone a la mayor felicidad y menor probabilidad de sufrir un mal cardíaco.

Otros especialistas dijeron que la felicidad misma podría redundar en un corazón más sano comparado con emociones tales como el estrés o la depresión.

El estrés suele liberar hormonas que pueden ser dañinas para el músculo cardíaco. También puede provocar dilatación excesiva de los vasos sanguíneos, lo cual permite que las placas en las paredes de los vasos se desprendan y formen tapones, dijo Joep Perk, vocero de la Sociedad Cardiológica Europea, quien no participó del estudio.

"Suelo decirles a mis pacientes que no se depriman demasiado porque es malo para el corazón", dijo Perk. "Se necesita tiempo para recargar las baterías, caso contrario el corazón no lo soporta".

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

The safety of aspartame is under review by WHO after conflicting findings.

Aspartame, a sweetener with health effects Since 1981, the WHO expert committee on additives has confirmed the safety of aspartame consumption within acceptable daily limits. The international organization has established that the acceptable daily intake (ADI) of aspartame is 40 milligrams per kilogram of body weight. This means that a person can consume up to 40 mg of aspartame per kilogram of their body weight per day without risking their health. For example, if someone weighs 60 kilos, the allowable amount of aspartame would be 2,400 milligrams (40 mg/kg x 60 kg). In recent years, several studies have been carried out on the effects of aspartame on health. The Food and Drug Administration (FDA) has reviewed the scientific evidence related to the safety of this sweetener five times since its approval in 1981, and has concluded that it remains safe for use. However, it is being studied again. It has an especially important use in low-calorie beverages consumed by children and pregnan

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
