Many Uses for Car Diffusers
1. Motion Sickness
We have all had the feeling of nausea and motion sickness at one time or another. As a kid, I remember the roller coaster ride making me feel dizzy. Planes, boats, ships, and rides at amusement parks can do it too, including cars and other vehicles on the road.
This happens when your body, inner ear and eyes send opposing messages to your brain. When your inner ear perceives a rolling motion, your eyes might not see it.
When you sit in the back seat of a vehicle where you cannot see out the windows can also cause this feeling that is uncomfortable.
Most kids between 2- and 12-years of age usually feel this sensation. Pregnant women will feel nauseous during their first 3-months of pregnancy. If you’re pregnant, get a pregnancy pillow, close your eyes and take a refreshing nap.
Use peppermint in the car diffuser because it’s good for the stomach to calm and soothe it. Turn off the ignition and close your eyes and open windows for some fresh air. Ginger is also good for the tummy, and kids can suck on crystalized ginger slices available at health food stores. They must be refrigerated after opening. Put the peppermint and/or ginger on a sugar cube and suck or chew it.
2. Staying Cool on Hot Days
Air conditioners don’t cool your vehicle the instant you start it on a hot or humid summer day. If your vehicle sat in the sun all day while you worked, it is hot inside. A number of essential oils have a cooling impact to help your body feel cooler.
- Roman Chamomile
- Menthol blends are cooling
These oils can be used in your vehicle with a diffuser.
3. Staying Wide-Awake When Driving
You must be fully alert when in all the current traffic and when taking long trips alone or with family or friends, including the dog. Deer and other wildlife cross highways and country roads at night, and kids and pets dart into the streets. Sometimes we don’t feel so alert and wide-awake on a long drive.
Some essential oils to keep you perky and alert are:
Simply put a dab on your temples, wrists, ankles, and feet to keep you wide awake and focused.
You can also blend some oils and put into a small spray bottle. These blends will stimulate and revitalize you. If you become more tired, take a break, find a motel, and get the good rest you need. Use the following recipe in 4-ounces of water. Do not spray near your eyes or passengers’ eyes.
- Peppermint 110 drops
- Cinnamon 35 drops
- Lime 35 drops
- Patchouli 20 drops
Top 10 Best Essential Oil Diffusers for Your Car and Vehicles
I am an advocate for aromatherapy and have many units. Here I am listing the best portable oil diffusers and rechargeable essential diffuser reviews for your awareness to choose from. I’m sure you will be pleased with the selections to have it your way.
None of the car diffuser reviews below use batteries. They use USB cables for USB ports or cigarette lighters and can be plugged into your laptop as well. Some come additionally with an adapter for a home wall outlet and if not.
If you don’t have a cup holder in your vehicle, you could use a clip-on cup holder that would lock into the vent or your door. All diffusers for car travel reviewed below are ultrasonic. That means they use water.
1. Syntus® Ultrasonic USB Car Essential Oil Diffuser, 50 mL
