Consider trying one of the following methods of using essential oils for aromatherapy.
Inhalation
Inhalation is an easy way to get the benefits of essential oils. You can use a vapor diffuser to fill the air with fragrance by adding the recommended number of drops of oil to your device. Or you can try an at-home facial with an aromatherapy steam treatment by adding essential oil to a bowl of water that’s hot enough to emit steam — up to six drops of oil per ounce of water — and inhaling with your face near the bowl.
Be careful when it comes to using diffusers, however — essential oils contain volatile organic compounds (VOCs) that get released into the air; these are known to be harmful to human health. While the long-term effects on the body aren’t known, one study that followed 200 essential oil users over more than a decade found that those who used aromatherapy for more than four hours per day had increased blood pressure and heart rate; those who used essential oils for less than an hour daily didn’t. Diffusers can also harbor mold and bacteria, which may lead to infections, and for this reason, experts often recommend against using them.
You can also try oil-filled nasal inhalers that you hold near your nose and sniff, room sprays, vapor balms, or directly inhaling the scent from a few drops of oil poured on a tissue or a cotton ball.
Always use essential oils in a well-ventilated room, make sure to thoroughly clean your diffuser to prevent microbial growth, and follow dilution instructions for the method and the specific oil you’re using, and trust your own body’s response — aromatherapy affects everyone differently. Additionally, make sure your pets are free to leave the area if the scent bothers them.
Applying It to Skin
In addition to potentially causing irritation via allergies, sensitivities, or inadequate dilution, some essential oils are photosensitive and react to ultraviolet (UV) light, like sunlight. They can cause second- or third-degree burns when they’re applied to skin that’s then exposed to sunlight. Essential oils such as those derived from citrus, angelica root, and cumin seed are among those known to be photosensitive, but double-check the properties of any oil you use if you’re planning to be in the sun.
