Los celos en mujeres y en hombres son distintos por razones evolutivas y psicológicas

La mayoría de las mujeres ven la infidelidad emocional como algo peor que la infidelidad sexual, mientras que los hombres son más celosos con este segundo tipo de infidelidades, señala un estudio realizado por psicólogos de la Pennsylvania State University, en Estados Unidos.

Esta diferencia entre ambos sexos en la valoración de las infidelidades se da en todo el mundo, aseguran los científicos, y podría tener un origen evolutivo.
Al parecer, los hombres han aprendido durante eones a estar muy atentos en lo que se refiere a la sexualidad de sus parejas, porque nunca han podido estar completamente seguros de ser el padre de sus hijos. Las mujeres, por el contrario, se han preocupado siempre de tener un compañero comprometido con sacar adelante a su familia.
A raíz del presente estudio, los científicos sugieren, además, una explicación alternativa y más psicológica: los celos dependen de la confianza y el apego emocional de cada individuo. Algunas personas se sienten más seguras que otras, por lo que los celos de distinto tipo vendrían determinados por múltiples factores. Por eso, potenciar la seguridad emocional en las personas de ambos sexos podría ser un medio efectivo para reducir la desconfianza y los celos.

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
