AAA: How Long Should I Diffuse?

AAA: How Long Should I Diffuse?

Diffusion is one of the most prevalent ways to enjoy essential oils and obtain their natural benefits. As aromatherapy lovers ourselves, we admit to getting carried away with diffusing. We love switching on the diffuser in the morning, noon and night to help alleviate stress, create an aromatic atmosphere, keep germs at bay — you name it. But just how long should you leave the diffuser on? Don’t miss this commonly overlooked essential oil safety tip.

Habituation

Have you ever used an essential oil continuously, then noticed it didn’t work as well as it once had or that you’ve become nose-blind? It may be that your body has adapted to that oil, rendering it less effective than when you had first used it. Most people are familiar with the way you can build up a tolerance to alcohol and medications. This is known as habituation, and it can occur if you use the same substance too often.

Luckily, you can avoid habituation by alternating the essential oils you use and by reducing the duration you use them. Along with limiting topical use of essential oils, restricting your diffuser’s “on” setting is another way to prevent your EO tolerance.

Safety Issues

Along with essential oil habituation, there are safety issues at play when it comes to prolonged essential oil exposure.One study showed that after an hour of being exposed to essential oils, volunteers experienced increased heart rates, which researchers concluded could be harmful to heart health. However, the same study revealed a 15-60 minute EO exposure resulted in deeper relaxation and decreased heart rate.Overexposure to diffusion can also lead to headaches, dizziness, nausea, brain fog and more. Thus, the importance of limiting your diffuser time can’t be understated.

How Long Should I Diffuse?

So just how long should you keep the diffuser on? With an active diffuser, such as the Diamond Diffuser andCeramic Ultrasonic,30-60 minutes on and 30-60 minutes off is recommended for preventing habituation and overuse of essential oils. A shorter interval may be warranted for young children, the elderly and those with compromised health. If you wish to diffuse for longer periods, passive diffusers, such as theCeramic Bloom andReed Diffuser, are a safe option as they emit lower concentrations of essential oils than active diffusers. As we like to say here at Edens Garden, less is more when it comes to EOs.

Diffuser Intervals

Ceramic Ultrasonic Diffuser: 

  • 1st Interval: Continuous diffusion
  • 2nd Interval: 30 seconds on/30 seconds off

Diamond Ultrasonic Diffuser:

  • 1st Interval: 3 hours of continuous diffusion
  • 2nd Interval: 8 hours of intermittent (30 seconds on, 30 seconds off) diffusion
  • 3rd Interval: 1 hour of continuous diffusion
  • 4th Interval: 2 hours of continuous diffusion

The Diamond Diffuser’s third interval makes it easy to abide the 60-minute “on” rule. With the Ceramic Ultrasonic and the Diamond Diffuser’s other intervals, a timer is a good way to ensure you’re not treading into overexposure territory.

Hi KAJ! There’s no hard and fast rule with the 30 seconds on/ 30 seconds off function, but we would say an hour and a half to two hours would be best.

So one should really only do continuous diffusion for one hour at a time.

If you are doing the 30 seconds on and 30 seconds off, how long should the total time be?

Hi Margaret! Try filling your diffuser 1/3 full or with 33 ml of water. This way, your diffuser will turn off after an hour.

I purchased your ceramic Ultrasonic diffuser. I didn’t realize it only had 2 settings. Not one for 1 hour. Will 30 on and 30 off work for my bedroom when I go to bed

Hi Kathryn! It depends on your diffuser. We recommend 10-15 drops per 100 ml and 90 ml of distilled water for our diffusers, but other diffuser manufacturer’s may have a different recommendation.

Hi Thomas! An air purifier may deviate the benefits of an essential oil diffuser, especially if it has a deodorizing feature. I would recommend running each device separately.

Hi JRB! Thank you for your feedback – we did mean “alternating.” 😉

Will an air purifier deviates the benefits of running a diffuser?

Luckily, you can avoid habituation by altering the essential oils you use and by reducing the duration you use them. Along with limiting topical use of essential oils, restricting your diffuser’s “on” setting is another way to prevent your EO tolerance.

Please adjust the word “altering” to “alternating”: (Luckily, you can avoid habituation by altering the essential oils you use and by reducing the duration you use them.

ALTERING means to change, as in to change your mood. Altering an oil would mean adding something to it or doing something that would change its essence or aroma.
ALTERNATING is to change, as in to switch between two or more things.
From the context of what you wrote, ALTERNATING is the word you want to use.
Thanks :)

Hi Martha! The longer the oil in water sits, the more it will lose its potency. The oil will oxidize and the water in your diffuser will begin to grow microbes. With that said, we recommend using the mixture in your diffuser as soon as possible, and no longer than a week.

Just recieved my diamond diffuser and LOVE it, but I’m new to this and unsure how many days I can use the same water and oil in the diffuser.
For example: this is day 3. Diffuser still has water. Will it be alright if I don’t turn it on for 2 or 3 days and then use the same water/oil blend? One week out?
Does the oil “grow stale” or loose it’s potency the longer it sits?
