A recently reported side effect of menopause—an acute and sometimes unbearable heightening of the sense of smell—has cast light on an under-recognised health issue affecting women globally, including in Thailand. While hot flashes, mood swings, and sleep problems are well-documented hallmarks of menopause, women are coming forward with distressing accounts of ordinary smells becoming intolerable, wreaking havoc on daily life and relationships. Medical professionals admit that the problem is little understood, and concrete solutions remain elusive, leaving many women without adequate support.

Smells can linger in memory long after the scent fades, shaping mood and behavior. A new study from the University of Florida reveals how the brain assigns emotional value to odors, offering fresh insights for sensory health and potential clinical treatments. The research shows that odor experiences are not just about smell notes—they’re tied to deep brain circuits that determine what we find pleasant or aversive.

In Thailand, where street market aromas swirl and local foods like pla ra (fermented fish) and other pungent scents are integral to daily life, the subjective nature of “good” and “bad” smells is more than a curiosity. As Bangkok and other cities become more diverse, understanding how the brain chooses which odors to embrace could impact mental wellbeing and everyday experiences, including healthcare environments.

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.
