#Olfaction

Latest scientific research is dismantling the myth that humans are “bad smellers,” revealing that our sense of smell is not only ancient but deeply intertwined with memory and emotion—a connection far richer than previously thought. This new understanding sheds light on how even a simple whiff of a familiar odor can instantly transport us back in time, evoking powerful memories and emotions, and opens the possibility of harnessing scents in therapeutic, educational, and cultural contexts in Thailand and beyond.

A whiff of microwaved fish may linger in your kitchen—and your memory—but what makes some smells universally unpleasant while others draw fond nostalgia? Recent research from the University of Florida uncovers how our brains assign emotional value to odors, offering insights that could reshape approaches to sensory health and even clinical treatment of scent-related distress (SciTechDaily).

For Thais who cherish the bustling aromas of street markets or the stinging tang of fermented fish (pla ra), the subjective nature of “good” and “bad” smells is more than a curiosity—it’s a matter woven into daily life, heritage, and even mental wellbeing. As major Thai cities grow ever more cosmopolitan, and with mental health awareness rising, understanding exactly how our brain selects which odors to embrace (or reject) could have widespread impacts.
