Using an Oil Diffuser in Your Car

Of the five senses, our sense of smell is quite unique. One whiff can tell us what's cookin' in the kitchen or trigger a memory from years gone by. Perhaps it should be called our scents of smell.

While all the senses are of course important, your sense of smell actually has the power to change your performance and enhance your mood. It’s true, and by surrounding yourself with the right scents you can enhance your life through the power of smell.

The average person spends hours driving in their car every day. Being in the car or being stuck in traffic for long periods of time can be stressful and tiring. However, did you know you can use this stuck in the car time to lift your spirits and rejuvenate your soul? It's true, the natural chemical compounds found in essential oils can change your mood, outlook, and perhaps even your life.​

Mobile Aroma Therapy

Aromatherapy is the practice of using plant-based oils to improve your psychological or physical well being and this relaxing discipline can now be enjoyed while driving. The underused time spent in your car can quickly turn into the highlight of your day when incorporating this practice. Whether it is to clear your sinuses, calm your digestive system, or simply finding some precious relaxing you time, with an essential oil-diffuser, you may find yourself even looking forward to getting into your car.

At Organic Daily Post we checked out some of the best diffusers and here's what we learned about them.​

Two Steps to Auto Aromatherapy

Turning your car into a mobile aromatherapy haven is easy. Follow these two simple steps and get in on the impressive curative power of essential oils.

1) Choose Your Favorite Essential Oils

First things first. Make sure you get the essential oils that you like best for use inside your car. You can use the list provided you below as a reference. A note of caution. Make sure to avoid any too soothing or relaxing scents that might relax you too much and cause you to nod off at the wheel. If you have other scents you would like to use that aren’t on the list, do a little bit of research on them first to make sure that they are safe and appropriate for use in the car. Once you are comfortable with your choices, get creative and have fun combining various scents to create a fragrance sure to give your car that personal touch.

Important Note: Whichever oils you purchase, choose oils of high quality. Remember, you're breathing this vapor into your lungs so essential oil is not a product you want to cut corners on.

2) Choose Your Method of Diffusion

The next step is to choose your diffusion method. Car diffusers offer several different looks and in varying styles. Some models mount in your cup-holder, or in the cigarette lighter while some even clip to your air vent.

Important Note: Whatever you choose for an oil, make sure that the oils you purchase are high quality. Remember, you're breathing this oil into your lungs so essential oil quality is a terrible place to cut corners.
