How To Rewire Your Brain With Aromatherapy

Smell Affects The Brain

Scent triggers an emotional response both at a psychological and physiological level – think how you associate the coconut-y smell of sun cream with lazy summer days and the aroma of cinnamon and nutmeg with Christmas. “This all comes down to your limbic system, one of the deepest parts of your brain,” explains Dr Tara Swart. “When you smell something, this is detected by your olfactory nerve, which connects the nose to the limbic system. The limbic system manages memory, navigation and intuition and induces emotional states, such as calmness, motivation and sleepiness. This is exactly how aromatherapy works.”

Your Brain Is Malleable 

“Science has proven the brain is flexible, and this is called neuroplasticity. Science has also shown aromatherapy plays a key role in altering brain waves, reducing the perception of stress, decreasing levels of cortisol (the stress hormone) and triggering positive emotional responses,” Tara says. Moreover, following daily rituals using specific essential oils can rewire your brain. “Rituals are important and recent discoveries about neuroplasticity show we can change our neural pathways through, for instance, using a mindful sensory ritual that includes aromatherapy to start your day,” she says. For example, if you took a regular bath containing the same oils, your brain would soon associate those smells with relaxation and positive emotions, she explains.

The Right Blends Are Key

The smell of freshly cut grass may induce happy memories of spring days, but research shows it’s aromatherapy which has the power to change the brain’s structure. “When it comes to specific essential oils, studies show vetiver can work wonders to relax and sedate; chamomile promotes deep sleep and decreases stress levels; while sandalwood is a strong tool for anxiety. When it comes to boosting mental focus, clarity and memory, look to citrus-based oils, such as grapefruit. Rosemary is also well-studied for its effects on memory, while lavender is nature’s strongest neuro-modulator, providing calm when we are agitated and focus when we need it,” says Tara. Her top tip for buying the best essentials oils? “You get what you pay for – look for 100% essential oils made in small batches or professional, high-quality blends.”

Your Own Ritual Will Help

“If you are going through a period of increased stress, try to establish a morning and night-time ritual with additional boosters throughout the day. It’s worth noting different formulations deliver different strengths of essential oils – bath and shower oils can be applied directly to the skin and inhaled, while sprays and mists are best for inducing sleep. Rollerballs are also a portable way to incorporate a little mindfulness into a hectic day, allowing you to tap into refreshed energy when needed,” Tara says. “And while essential oil-based candles and diffusers might smell nice, they’re nowhere near as potent and don’t have the same effect on the olfactory nerve.”
