How does our sense of smell work? Smell (also known as olfaction) happens when chemicals in the air enter the nose as part of the breathing process. We have millions of smell receptors which lie in the top of the nasal passage. These receptors send impulses along the olfactory nerve to the olfactory bulb at the base of the brain.
This area of the brain is also where our limbic system is located - think memory and emotions. The limbic system is pretty nifty. It regulates endocrine function (glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things) based on emotional stimuli.
This is why aroma is such a powerful tool in helping support emotional and physical health. Of course, there are many factors that affect our individual sense of smell - hunger, context and expectation to name a few.
Hunger and appetite - ever noticed how the smell of freshly baked bread can make you ravenous, even if you have just had a main meal??
What about context? I LOVE the smell of horse poo. It takes me back to my youth where I spent many happy weekends with my Pa looking after his horses. You however, may be repulsed by the smell of manure.
Expectation - think of a blind smell test of heavily aged parmesan cheese mixed with a super ripe provolone. Imagine if I blindfolded you, got you to take a big whiff of this cheesy goodness but TOLD you it was vomit. What do you think your reaction will be??
On another note, the three pictured essential oils make a glorious diffuser blend. 3 drops of lemongrass (cleansing), 3 drops of tangerine (creativity) and 1 drop of the mighty spearmint (communication).
