Essential oils don't just smell great; they also have a wide range of therapeutic benefits that can help you feel better and boost your overall sense of wellbeing. The use of essential oils for medical purposes--aromatherapy--dates back thousands of years. Since some essential oils are poisonous and others can irritate your skin, one of the best ways to reap their benefits is with an ultrasonic aroma diffuser.

 

Diffusion releases the molecules of the essential oils into the air and is the safest way to enjoy the beneficial effects of essential oils on your brain, nervous system and overall health. In this article, we'll look at some of the primary benefits of having an ultrasonic aroma diffuser as well as some of the top models available on today's market.

Aromatherapy & Ultrasonic Aroma Diffuser FAQS


If you are new to aromatherapy or looking for a reliable ultrasonic aroma diffuser for your home or office, there are a few things you'll want to consider before you set on your olfactory journey.

 

1. What Is Aromatherapy?

Aromatherapy is the practice of using the aroma or smell of natural oils extracted from the leaves, bark, roots or flowers of plants to support psychological and physical health and wellbeing. Ultrasonic aroma diffusers are one of the primary methods for delivering essential oils into the air of your environment and from there into your body.

 

2. What Are Essential Oils?

Essential oils are highly concentrated versions of the natural oils and compounds in plants. They are typically obtained by distillation to preserve and augment the characteristic smell and flavor of the original plant.

 

3. What Are the Benefits of Aromatherapy?

When you inhale the oils as they disperse into the air, they work directly on your brain and nervous system and have an immediate impact. The unique smells of different plants will have a variety of effects on your body. The benefits are wide-ranging, but some of theprinciple benefits include improved sleep, increased energy, reduced stress and anxiety, improved digestion, and a stronger immune system.

 

4. How Can I Learn Which Essential Oils Do What?

There are books, classes, and a wealth of internet sources to help you learn about which essential oils treat certain conditions. Some essential oils like lavender are well-known stress and anxiety relievers, while peppermint can lift your mood. If you want to learn more about the physiological and psychological effects of essential oils, the best place to start is with an internet search. You can find basic information on what oils work best for different conditions as well as books on the subject and list of local and online classes that will help you learn about the topic.

 

5. How Does an Ultrasonic Aroma Diffuser Work?

Ultrasonic Aroma diffusers use electricity to disperse essential oils combined with water into the air. The oil doesn't actually mix with the water.  The ultrasonic vibrations agitate the water and separate the oil molecules so that they disperse into the air in a fine mist. 

 

6. Where Can You Buy an Ultrasonic Aroma Diffuser?

Ultrasonic aroma diffusers are available at most health stores and online at Amazon and other retail outlets.
