When you send droplets of essential oil into the air, you’re continuing a practice that may have existed thousands of years ago. Aromatherapy is the practice of applying the fragrance of plants or herbs attracts for physical and mental enhancement.

No one knows exactly when the practice of aromatherapy first started. However, an archeological finding suggested the use of herbal plants was practiced in Egypt 60,000 BCE. It was also believed that ancient Egyptians uses plant extracts for embalmment.

The uses of essential oil for mood enhancing purposes was believed to have originated from China thousands of years ago. Other regions around the world also featured in the history of essential oil. However, the word ‘aromatherapy’ was coined in 1937 by a French chemist, Rene-Maurice Gattefosse, following a burnt that trigger his interest in the therapeutic properties of the essential oil.

How Essential Oil Diffusers Work

Aromatherapy promotes healing by inhaling the vapor of essential oil. There are a few ways to achieve this and one includes the use of an essential oil diffuser. Essential oil diffusers are a vital instrument in aromatherapy that disperses essential oil droplets into the air.

Back then, when electronics are non-existence, the easiest way to disperse essential oil is by using a candle. But today’s technology means there are more efficient ways to diffuse essential oil. Here are four types of essential oil diffusers that you’ll encounter.

1. Nebulizer

Nebulizing diffusers don’t need water to function and there’s no heat involved when dispersing essential oils into the air. It uses an atomizer which creates tiny particles of essential oil by applying a stream of highly pressurized air.

A nebulizer creates highly concentrated of essential air droplets in the air but also uses up the oil quickly. It is also comparatively more expensive than other types of diffusers.

2. Ultrasonic Diffuser

The ultrasonic diffuser is commonly used by aromatherapists today. It doesn’t use any heat in sending off essential oil particle into the air. Instead, a vibrating mechanism vaporizes the essential oil mixture.

To use an ultrasonic diffuser, you’ll need to dilute the essential oil into the water. Ultrasonic diffusers are relatively quiet, inexpensive and do not involve heat.

3. Evaporative

Evaporative diffusers leverage on the natural characteristics of essential oils which vaporize easily. Some evaporative diffusers involved placing drops of oil onto an absorbent pad and uses a built-in fan to turn the oil into vapor. Others, like pendant and bracelets, allows the oil to evaporate naturally.

While these diffusers operate without heating elements, the coverage area is relatively small thus limiting its usage.

4. Heat Diffusers

Heat diffusing involves candles that applies heat on essential oil. It is the cheapest form of diffusers and does not require electric power to run. However, this also means there is no control on the diffusion rate and may be wasteful to use.

Top Benefits Of Using An Essential Oil Diffuser

With an essential oil diffuser, your home will soon be filled by the aromatic scent of your choice essential oil. But having a pleasant scent isn’t the only reason to get an essential oil diffuser. Here are other benefits that you and your family will receive from having an aromatherapy diffuser.

With so much in your mind, sometimes sleep can be elusive. Placing a diffuser in your room and using essential oils for sleep, like lavender, can ease your mind into slumber without going through the usual struggle.

3. Boost Cognitive Function

Essential oils like frankincense, sandalwood, and rosemary are known to improve cognitive function.  A study on the effect of frankincense on rats suggested positive links between the essential oil and memory improvement.

4. Boost Immune System

Certain essential oils have antibacterial and anti-fungal properties and are helpful in boosting your immune system. Diffusing essential oils like eucalyptus, cinnamon and peppermint can work wonders in warding off flu and cold.

5. Repel Insects

Stop spraying pest repellants that contain harmful chemicals. Instead, dispersing essential oils like tea tree oil and lemongrass help to keep bugs and insects away from your home.

6. Safer Alternative To Scented Candles

How To Choose The Right Essential Oil Diffuser

Choosing an essential oil diffuser can be rather intimidating, especially if it’s your first time shopping for one. It’s tempting to bring home the cheapest one available, but that’s rarely a wise decision. Here are some pointers to help you out.

  • Heatless – Generally, heat destroys the therapeutic properties of the essential oil. Avoid using diffusers that operates with heat. Instead, choose ultrasonic, nebulizer or evaporative diffusers.
  • Coverage Area – Essential oil diffusers are built with different capacity. Some are great for a bedroom while others are powerful enough to send droplets to the entire living room.
  • Aromatic Strength  – Some individuals may prefer a stronger scent of essential oil in the air. In this case, a nebulizer will be the right choice as it sends undiluted essential oil to the air.

How To Clean Your Essential Oil Diffuser

If you’re lazy to clean your diffuser, be prepared in replacing with a new one soon. Some essential oils can corrode the parts on your diffuser. That aside, the efficiency of essential oil can be reduced by the residues of the last use.

Cleaning an essential oil diffuser is pretty simple, and there’s no excuse for doing so. Just use a microfiber cloth to rub off any water or residues each time after usage. Occasionally, like once a month, you can wipe the diffuser with alcohol, or mix white vinegar with water and let it run for 5 minutes.
