NCHS Grief & Wellness Series: Scent & Grief
Part 2: What is Scent?
Our olfactory system, or sense of smell, is one of the five senses that keeps us safe in the world. The nasal cavity is filled with millions of tiny smell sensors that pick up and identify over 10,000 aromatic molecules by their specific chemical shape.
Our olfactory system is connected to the limbic system in the brain which is responsible for emotions and memory. The limbic system deals with automatic responsive behaviours and has little, if anything, to do with conscious thought or will.
When our olfactory receptors identify something that is not pleasing (unsafe), we become alert for threats, and our bodily response will be too tense up and prepare us for action. This is known as the sympathetic state. Conversely, when we smell something that is pleasing, we enter a calmer - more relaxed - state and activate a parasympathetic state of the nervous system.
Once we make the conscious connection to how smell affects us, we have within us a very powerful tool that we can use to support ourselves and bring about changes to our physiology. We can create more relaxation and find comfort any time we need to. To put it simply - If it smells good, it feels good.
In moments when we may be feeling anxious and overwhelmed by our surroundings, fatigued and off-balance by our environment, confused, unfocused, hyper-focused, or even deep into an emotional meltdown, just inhaling a smell that pleases us calms our central nervous system.
