Lately, my sense of smell has been fooling me. I’ve been haunted by a scent that’s not actually there. It’s kind of funky, but not awful, kind of like what I imagine a cold sweat would be.
This smell that doesn’t actually exist first appeared about a year and a half ago during a very stressful time in my life. At first, I thought it was me, but sometimes I would smell it right after I’d had a shower. I asked the people around me if they smelled what I was smelling, and no one did. Ultimately, I realized that was I was experiencing phantosmia or olfactory hallucinations.
When I realized that I was the only one detecting this smell, it kind of freaked me out. But over time I’ve come to realize that it’s a weird response to stress. I only smell it when I’m acutely stressed. When all is good, the smell is gone. Go figure.
I’m telling you about my phantom smell because it’s easy to forget that your sense of smell and your brain are connected. This connection can be a powerful tool for healing, and is the foundation of aromatherapy. In the same way that guided visualization or music supports healing through sound, and massage heals through touch, the use of scents can be therapeutic as well.
Scent can affect your brain in a variety of ways. In fact, research has shown that one of the most powerful triggers for memories is through your sense of smell. When you detect a scent, those molecules stimulate the nerves in your nose, which trigger electrical impulses in the olfactory area of your brain. Those impulses are then transmitted to the amygdala, an area of your brain where memories are stored.
In Chinese medicine, the sense of smell is used in a number of ways. Odors can be a helpful diagnostic tool. If a patient has a strong smell, it can be a tip-off to a number of conditions. If they’re sweating, the smell and nature of when and how they sweat offers up clues. If a patient’s breath has an odor, it’s up to the practitioner to determine if the smell is coming from dental problems, lung issues, or poor digestion.
