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.

  • Eucalyptus
  • Grapefruit
  • Lavender
  • Lemon
  • Lime
  • Mandarin
  • Melaleuca
  • Peppermint
  • 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:

  • Basil
  • Lemon
  • Peppermint
  • Rosemary
  • Ylang-Ylang

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
