A recent breakthrough study, published in the journal Cell Metabolism, has identified an unexpected benefit of intermittent fasting: it can revitalize sexual behavior in aging male mice by reshaping the very chemicals in their brains that govern libido. With significant implications for how dietary patterns may influence aging and sexual health, the findings have sparked interest among aging populations worldwide, including Thai communities seeking ways to preserve well-being into later life (PsyPost).

A wave of new research is upending long-held beliefs about the “feel-good” brain chemical serotonin, suggesting its roles in everyday decision-making are far more intricate than previously thought. A recent article from MedicalXpress spotlights studies unveiling a complex serotonin system, revealing dynamic activity patterns that could revolutionize how scientists—and potentially clinicians—approach human behavior, mental health, and treatment strategies MedicalXpress.

For decades, serotonin has been popularized as a simple chemical messenger regulating mood, with its influence on happiness, depression, and anxiety immortalized in everything from health textbooks to Thai social media memes. In Thailand, where mental health awareness campaigns are gaining momentum and selective serotonin reuptake inhibitors (SSRIs) remain a first-line treatment for depression, understanding how serotonin truly affects everyday choices has wide-ranging implications. Scientific dogma once held that serotonin’s main function was to broadcast a basic reward or punishment signal, essentially nudging people toward or away from certain actions.
