Training your nose to perceive something other than cigarette smoke involves engaging in a form of sensory retraining known as olfactory training. The foundation of this approach is based on the brain’s ability to change and adapt called neuroplasticity. Introducing the nose to specific, concentrated scents over time can help alter its reaction to other odors. This method is akin to physical therapy designed for the sense of smell and has shown promise as a technique for those who suffer from anosmia or loss of smell.
Research suggests that olfactory training involves exposing oneself regularly to strong essential oils such as rose, lemon, eucalyptus, and clove. A 2009 study led by Dr. Thomas Hummel from the University of Dresden found that patients who used such essential oils showed significant improvement in their sense of smell after consistent exposure over 12 weeks. While this was primarily studied in the context of smell loss, the underlying principle is that the nose can be retrained to modify the way scents are perceived.
On the medical front, the phenomenon observed during the COVID-19 pandemic where people experienced changes in their sense of smell due to the virus offers insights into potential medical interventions. For instance, Dr. Carl Philpott of the University of East Anglia’s Norwich Medical School highlighted the potential use of steroids and retraining exercises in restoring one's sense of smell post-viral infection. Such studies suggest avenues by which sensory alteration might occur, ideally helping to repurpose one's sensory perception of cigarette smoke.
There are also practical, non-medical methods worth noting. The consistent avoidance of environments filled with cigarette smoke coupled with maintaining high air quality in living spaces could potentially aid in diminishing its impact. Using air purification systems might serve as auxiliary supports; albeit the data is often anecdotal regarding direct impact on smell alteration. It's important to consider sensory training as part of a holistic effort rather than a definitive cure-all.
It's clear that while the concept of completely altering one's olfactory response to cigarette smoke isn't over-the-counter simple, the combination of sensory retraining, avoidance strategies, and an improved understanding of olfactory function post-illness points towards promising avenues.
