How to Safely Use Essential Oils with CPAP Therapy (and What to Avoid)
Never put essential oils directly into your CPAP humidifier, mask, tubing, filters, or machine. These oils can damage your equipment, negatively affect your health, and interfere with effective CPAP treatment. If you want to enjoy aromatherapy while using CPAP therapy, scent the air in your room using a diffuser; not your CPAP equipment.
Safety Warning
Do not add essential oils to the water chamber under any circumstances. Essential oils can damage your CPAP machine and components and may also negatively affect your health and the effectiveness of your CPAP treatment.
Why People Use Essential Oils with CPAP
Some users find it challenging to adjust to CPAP treatment and may be tempted to use essential oils to make the experience more tolerable. If you feel that aromatherapy is beneficial to your well-being, you may consider using essential oils alongside your CPAP therapy.
Better Sleep, Less Congestion, Familiar Comfort
Many different oils have been reported to help with relaxation and make it easier to sleep. People use essential oils to improve sleep quality by reducing anxiety and promoting relaxation. While there isn't verified, peer reviewed scientific research proving that essential oils improve sleep during CPAP therapy, some users report feeling more relaxed and less anxious when using scents such as lavender.
The Right Way to Use Essential Oils with a CPAP Machine
The first and most important thing you need to know is to NEVER put essential oils in your CPAP machine, CPAP humidifier, mask, tubing, or filters.
If you choose to use aromatherapy with CPAP therapy, the scent should remain separate from your equipment. Essential oils should never come into direct contact with your machine or accessories.
Use a Room Diffuser Near the Bed
You can simply place a few drops of oil in a diffuser NOT your CPAP machine or any CPAP parts, and naturally breathe in the calming aroma, not the oil itself, while you sleep. A little goes a long way.
Apply Oils to Bedding or Pajamas
If you feel more relaxed and less anxious while using essential oils such as lavender, consider diffusing it for a set amount of time right before bed or place a small amount of essential oil on your arms or wrists.
Best Essential Oils for CPAP Users
Lavender: Sleep and Relaxation
If you feel more relaxed and less anxious while using essential oils such as lavender, consider diffusing it for a set amount of time right before bed.
Eucalyptus: Congestion Relief
Some users choose eucalyptus as part of their relaxation routine because of its refreshing aroma. However, it should only be used to scent the air in the room and never in CPAP equipment.
Peppermint: Easier Breathing
Peppermint is another popular essential oil used by people seeking a refreshing scent before sleep. As with all essential oils, keep it completely separate from CPAP equipment.
Chamomile, Cedarwood, Frankincense
Many people use a variety of essential oils to promote relaxation and reduce anxiety before bed. These oils may be incorporated into a bedtime routine through room diffusion or other non-CPAP methods.
What Happens If You Put Oils in the Humidifier?
Essential oils can interact with the components of your CPAP equipment, such as the mask or tubing, causing damage and limiting the equipment’s ability to operate properly. They may also negatively affect your health and the effectiveness of your CPAP treatment.
Essential oils do not provide any medical benefit to CPAP treatment; in fact, they can be a deterrent to effective treatment.
