If you’ve felt your sense of smell is slipping as you age, know someone struggling with dementia or Parkinson’s, or just want to boost your brain health with a simple daily practice, this episode is for you. Welcome to Aging In Full Bloom with Lisa Stockdale! In this episode, I sit down with my special guest, Jonathan Askholm, to explore the fascinating and often overlooked world of olfactory training—the art and science of strengthening your sense of smell. Together, we dive into how our nose isn’t just about pleasant aromas or powerful memories; it’s deeply connected to brain health, cognition, mood, and our overall well-being. Jonathan Askholm shares his personal journey—from corporate wellness into a passionate advocate for olfactory training—sparked by his own family’s experience and compelling scientific studies. Through our conversation, I discovered some surprising truths, like how the olfactory system is the only sense capable of regenerating neurons throughout life, and why smell training is now being recommended to improve memory, mood, and even help those recovering from illnesses like COVID-19. If you’ve felt your sense of smell is slipping as you age, know someone struggling with dementia or Parkinson’s, or just want to boost your brain health with a simple daily practice, this episode is for you. Let's learn why smell just might be our most underrated sense—and how it could become your secret weapon for healthy aging.

Regular, intentional exposure to specific scents can help sharpen your sense of smell and even regrow some neural pathways.Olfactory training boosts more than just your nose. Studies show it can improve memory, mood, and overall cognitive function, especially in older adults.It’s simple and affordable. All you need are concentrated scents like lemon, clove, rose, and eucalyptus—just a few minutes, twice a day, can make a difference. FAQ's What is olfactory training, and how can it benefit brain and memory health? Olfactory training is a practice using concentrated single-scent essential oils like lemon, clove, rose, and eucalyptus, intentionally sniffed twice daily to improve or restore the sense of smell. Scientific studies show this boosts brain and memory health and can enhance cognitive function, mood, and even flavor perception. How do you actually perform olfactory training at home? To perform olfactory training at home, smell four different concentrated essential oils (lemon, eucalyptus, rose, clove) twice a day for 20–30 seconds each, ideally using inhaler-style kits for safe, consistent use. Consistency is key: you’ll see noticeable results in the sense of smell and possible cognitive improvements after regular daily practice for several weeks. Why is olfactory training not more widely recommended despite strong scientific support? Olfactory training remains under-promoted because the sense of smell is the least understood and understudied sense in neuroscience, despite mounting robust studies confirming its benefits. As Jonathan Askholm explains, there is little public health messaging about it and general skepticism about such a simple, low-cost intervention, even though evidence and experts strongly support its use.
