Nearly everyone has a favorite scent and a substantial body of research supports the claims behind the use of aromatherapy to influence our mood and state of mind. The results of a randomized, controlled trial published in the International Journal of Neuroscience showed peppermint increased alertness, while ylang-ylang had a measurable effect in inducing calm and lowering stress. Other studies demonstrated the scent of lavender can reduce anxiety, while citrus notes of lemon, grapefruit and orange have an uplifting effect.

If you’re heading off on a road trip or weekend drive, diffusing the right scent within your car can add to your pleasure and help offset negative effects of traffic jams, road delays, noisy passengers and even the less-than-ideal playlist chosen by your traveling companions. You can hang a cardboard pine tree from your rearview mirror if you like, but far more aesthetically pleasing options are car fresheners created by CE Craft Candles. Each subtle scent is captured within an attractive glass vial diffuser that emits your fragrance of choice for up to two months.

Among the 35 signature scents are Nothing Good Starts in a Getaway Car, Apple Caramel Crisp, Bourbon Vanilla, Birthday Cake, Coffee & a Book, Flannel Musk, Fresh Linen and Hawaiian Sunset. The Folklore Scent has notes of vanilla blended with woodsy undertones and lavender, while Marshmallow Fireside captures the best suggestion of roasted marshmallow and a vanilla latte.

Dangle one from your mirror on the bottle’s self-tie leather cord, and control the strength of the scent by tipping the bottle from time to time. No need to choose just one — select from the collection’s four-packs, or bring along a candle to set up in your hotel room. A few of the many hand-poured, small-batch scent-sational choices: Taylor’s Cardigan and an array of road-trip perfect national park scents like Grand Canyon, Joshua Tree and Denali.
