Managing Fall/Winter Months, Day 8: Essential Oils- this one is a little long...
Let’s take a look at how essential oils are thought to work in the brain to help with depression...There is a connection between the sense of smell and other brain functions.
Smells travel as chemical messages via sense receptors and the olfactory nerve to the limbic area of the brain, and particularly to the amygdala and the hippocampus.
These are the areas of the brain associated with emotions (fear, happiness, etc), mood, pain, pleasure, and also with memories. Smells become associated with emotions, even memories of emotions. So, for example, if you use an essential oil while meditating, you learn to associate the fragrance with a state of deep relaxation. Over time, the same relaxation occurs with just the smell of the oil, without the meditation.
Studies have found that essential oils affect heart rate, stress levels, blood pressure, breathing, and immune function. And it’s been found that the molecules in essential oils are small enough to cross the blood-brain barrier. And once they enter the brain’s limbic system, they can have a direct impact on mood.
Sweet smells have been shown to reduce pain by activating the opioid receptors in the brain. There is such a strong connection between smell and emotions that people who lose their sense of smell often develop depression. Conversely, people who are depressed may have low sensitivity to smells.
There is a long list of oils recommended to help with depression. Some help because of their vibrant effect, like bergamot, ylang ylang, ginger. Some help because of their soothing, calming effect, like lavender and chamomile. Others to try include angelica, basil, cedarwood, sage, frankincense, geranium, grapefruit, jasmine and lemon.
