Why You Need A Diffuser: The Benefits of Inhaling Essential Oils

There’s a few misconceptions about aromatherapy and one is around diffusing. There’s this idea that diffusing isn’t necessary, and another one that it’s the only way to use essential oils. This is wrong. Diffusing is only one way to use essential oils, but it is one of the best ways. Aromatic use of essential oils is probably the most researched method of aromatherapy. So let’s talk why you need a diffuser.


Diffusing essential oils, specifically, has a positive impact on sleep. This study shows that diffusing lavender increased the percentage of deep or slow-wave sleep (SWS) in men and women. All subjects of the study reported higher vigor the morning after lavender exposure, corroborating the restorative SWS increase. Lavender also increased stage 2 (light) sleep.

Essential oils affect the nervous system. Try diffusing cedarwood, lavender and valerian.

Stress & Emotions

The nervous system is affected by essential oils and emotions are affected through your sense of smell and the limbic system. Certain essential oils like lavender have been shown to suppress heart stimulation and lower heart rate. Studies show that lavender, neroli, and roman chamomile reduce anxiety. Diffusing, and direct inhalation have an impact, as well as topical application.  Citrus oils like orange, tangerine, grapefruit, bergamot have also been shown to modulate mood and anxiety.


Both palo santo and sage have been used traditionally to clear energy. Most commonly, sage or palo santo bundles are burned and the smoke is used to clear the space, but I enjoy using the diffuser so there isn’t any smoke.

What is energy? It is the vibration at which your cells move. It’s measurable. You have it and so does everyone else and you need to clear it. It hangs around–it’s that feeling when you walk into a place and it feels weird and just off. Or that gut feeling when you meet someone who just makes your skin crawl.

An intentional clearing practice for yourself, your home space, your office space is vital. Especially for people who are empathic and are easily overwhelmed by others.

Concentration & focus

Diffusing peppermint and lemon increases focus and concentration and productivity. In studies, peppermint increases clarity and enhances memory, and enhances cognitive performance and reduce mental fatigue. Basil essential oil has also been found to improve cognitive function, as well as vetiver essential oil. Diffuse in a classroom, office, even a car, to increase concentration, clarity and focus.

Purify the air

Studies show that the popular Thieves oil has a 96% airborne kill rate. The botanicals contained within it (cinnamon, clove, eucalyptus radiata, rosemary, lemon), specifically cinnamon and clove, have been shown to inhibit bacteria.
Diffusing is just one way to use essential oils. It is one of the most popular and familiar methods of aromatherapy, and it is effective. Make sure to only use high quality, real, verified essential oils that actually come from a plant. Manufactured or adulterated “essential oils” are unlikely to provide benefit.
