How Aromas Affect Body and Mind Health
You probably take your sense of smell for granted – but did you know that both your physical and emotional well-being depends on it? Aromas abound in all parts of our lives – some positively and some negatively – but if you were to lose your sense of smell, it may affect your quality of life, in addition to affecting some of your other senses. Here’s a quick look at why you should value your sense of smell.
The Connection Between Smell and Taste
Olfaction, otherwise known as the sense of smell, is the only sense with a direct link to the brain. The sense of smell is connected to the sense of taste. The nose is capable of detecting a lot more smells than the ear can in sounds, and the nose is also capable of detecting over 10,000 different types of smells. Up to 90% of what you taste is actually smelled. If you have a dog, you will know that a dog is capable of detecting a lot more smells than a human can – and its nose is highly stimulated a lot of the time! My dog uses his tongue a lot of the time when “sniffing” out aromas, positive confirmation that smell and taste are connected in his world.
How Aromas Enter Your Nose
Simply put, your nose inhales a specific smell, chemically converts it and then passes that information to your brain. Electrochemical messages are sent to the appropriate part of the brain, triggering the release of neurochemicals and causing subsequent effects. Of course, the whole process is a lot more complex than it sounds – but offset that against the fact that it happens in a matter of seconds and you can see what an amazing process it is!
The Importance of Smell
Your sense of smell allows you to identify the fragrance of a flower or an aroma of your favorite food; certain smells trigger memories of a specific, time, place or person – both positive and negative experiences. Your sense of smell can also help you to identify danger; for example, fire. A loss of your sense of smell can alter your perception of taste. Losing your sense of smell has a significant impact on your life.
Causes of Smell Disorders
Some people lose their sense of smell, either permanently or temporarily. Smell disorders can be caused by a number of factors which include the following:
nervous system disorders, including Alzheimer’s disease and Parkinson’s disease
polyps in nasal cavities
head injuries (frontal lobe)
solvent and insecticide exposure
Scent and Aromatherapy
Aromatherapy aims to improve your well-being by using, primarily, your sense of smell. Although aromatherapy works in a couple of ways, the quickest way in which essential oils access the body is through inhalation of the nose. Hence: Aroma-therapy.
Inhalation is also one of the most effective ways to treat emotional problems in aromatherapy.4 This is probably why many people associate the practice of aromatherapy with the treatment of stress, depression, and anxiety. Although the scope of aromatherapy practice is much wider than this, it is true that many essential oils are suitable for relieving the symptoms associated with emotional problems, specifically through inhalation. Aromatherapy diffusers, personal inhalers, and roll-on aromatherapy applicators can be used ineffectively in these situations. Some of the essential oils that are used to assist with emotional health issues include:
Smell, Aromas, and Your Health
As an aromatherapist, I am well aware of the power that scent has on my own health. In fact, since I started working with essential oils over a decade ago, my own sense of smell has become more acutely aware of the difference between “good” smells and “bad” smells. And I am not just talking about the difference between natural scents such as rose and horse manure! Exposure to synthetic fragrances and highly chemicalized products often induces nausea and headaches in me, to the point that I can not be in the same space as women who wear synthetic, commercial perfumes, or homes which use highly toxic household cleaning products.
