Why should You Diffuse Essential Oils?

One of the most powerful senses we have as humans is the sense of smell. There are smells that are so embedded in your mind that they bring up different memories every time you smell them. By adding fragrance to your home, you’re providing the opportunity to commit this fragrance to your memories. Fragrances can also influence the way the environment feels so by adding fragrance, you’re enhancing the way your home feels.

Essential oils are more than just a great way to fragrance a space. Diffusing essential oils can provide you with medicinal benefits that can keep your mind and body functioning well. Each essential oil has a different benefit for your mind and body so you have a large variety depending on what benefit you want to receive.

When you diffuse essential oils, you’re benefiting from something called aromatherapy. The best ways to benefit from aromatherapy are through inhaling the oils while diffusing or through the oils being absorbed into your skin when applied topically. Either way, you can benefit from aromatherapy either strongly or subtly. Everyone is affected to different degrees from aromatherapy.

Some of the benefits you can get from aromatherapy are:

  • A boost in your immune system
  • An environment without harmful viruses and bacteria
  • Odor elimination
  • Relaxation
  • Improvement in your focus and concentration
  • An improvement in your mood and energy and a lack of stress

These are just a few of the countless benefits that you can get from diffusing essential oils. By diffusing oils you’re opening up opportunities to not only have benefits for you mind and body but you’re also creating an opportunity where you’re eliminating odors and creating a new fragrance memory.

Essential Oils to Diffuse in Your Car

There are several essential oils that are perfect to diffuse in your car. You can use oils that provide the benefits of staying alert and concentrated while driving and there are even oils that can be used to combat motion sickness.

If you’re looking to make sure you’re alert and concentrating while you’re driving, there are plenty of oils you can use. While it’s important to make sure you’re rested enough to be able to safely drive, these can help keep you alert and concentrated. They are in no way a replacement for sleep. Some oils that can be used to help you stay alert and concentrated while driving are:

  • Peppermint
  • Cinnamon
  • Basil
  • Spearmint
  • Rosemary
  • Lemon
  • Lime
  • Grapefruit

You can even blend some of these oils together to make your own personalized fragrance. Some good combinations would be lemon and lime, peppermint and spearmint, or lemon and basil. By diffusing these fragrances, either separately or in a combination, you’re going to promote concentration and awareness while you’re driving.

If you suffer from motion sickness, there are some essential oils that can help to curb your nausea. These oils that can help ease your nausea are peppermint, ginger, fennel, and spearmint. While they aren’t complete fixes for your motion sickness and should be paired with other preventative measures, they do help.

Not every oil is good to diffuse in your car, though. There are some oils that can promote drowsiness and should be avoided while driving. These oils include chamomile, lavender, clary sage, sandalwood, and sweet marjoram. When diffusing these oils, you’ll want to make sure that you’re at home, preferably getting ready for bed, instead of out driving as they can make you sleepy.

To diffuse oils in your car, there are several methods. Many companies have designed electric diffusers that are specifically made for use in cars. There are some that plug into your USB ports or your 12-volt ports. There are also diffusers that are rechargeable that don’t require to be plugged in at all times. If you don’t want an electric diffuser, you can also buy one that connects to your air vent and diffuses using your air conditioning or heat.

No matter what kind of diffuser you choose to purchase, or if you choose to make your own, your car will benefit from their use. You will notice that you’ll be more aware and awake and your car won’t have any unwanted odors lingering around. Your car will also feel more welcoming to anyone you may be offering a ride to.
