How Engaging Your Sense of Smell Can Sharpen Your Mind – Backed by Science
Have you ever caught a familiar scent that instantly transported you back to a vivid memory? That’s the incredible power of your sense of smell. But did you know it’s also closely tied to brain health—and may even help preserve cognitive function as you age?
Recent research, including a study highlighted in New Scientist, is shedding light on the link between olfactory training (or "smell training") and improved mental sharpness. Here’s what the science says—and how you can easily integrate this practice into your daily wellness routine.
The Surprising Science Behind Smell and Brain Health
The olfactory system—the part of your brain responsible for detecting and processing smells—is uniquely connected to areas involved in memory and emotion, such as the hippocampus and amygdala.
In studies led by neuroscientists like Professor Thomas Hummel from the University of Dresden, participants who practiced smell training (sniffing specific essential oils twice daily over several weeks) experienced improved olfactory function. Intriguingly, emerging evidence also links this practice with broader cognitive benefits.
Why? Because stimulating the olfactory nerve may help maintain plasticity in the brain—keeping it adaptable, responsive, and better protected against age-related decline.
What Is Smell Training?
Smell training is a simple, natural practice that involves sniffing four distinct essential oils (typically Lemon, Rose, Clove, and Eucalyptus) for about 20 seconds each, twice a day. The key is consistency and mindfulness—actively focusing on the scent as you inhale, even if it seems faint at first.
This technique was originally developed to help people recover from smell loss (like post-viral anosmia), but it’s increasingly being recognised as a broader wellness tool.
