Snoring. Mouth Breathing. Restless Nights.
If you’ve ever laid awake feeling your breath gets shallow or your chest tightens with every inhale, you’re not alone. Whether it’s from stress, anxious feelings, congestion, or poor breathing habits, sleep problems often start with the way we breathe.
When your nervous system is stuck in overdrive, it becomes harder to fall asleep, stay asleep, or wake up feeling rested.

Testimonials
I use the WellO2 device with the nasal mask each night before I go to bed. It has opened up my nasal passages and greatly improved my breathing. While it hasn't completely eradicated my snoring, my wife tells me I no longer sound like a Space Shuttle taking off!

DAVID S., UK
From the moment I started using WellO2, I noticed a significant difference in my lung strength and overall respiratory health. My breathing was no longer laboured when doing any form of exercise and has also helped reduce my snoring.

EMILY, UK
Have laid awake at night struggling with the pain and anxiety of my back condition, and I was skeptical, but using this twice daily for two weeks currently has shown a marked improvement in my comfort, especially in the evenings when it's time to fall asleep.

JAMES, UK
If you are willing to improve and investigate more about some of the benefits of the world of breathing/pranayama, voice development, or training of your lung capacity, this is a good product to complement your research.

OLIVIA M., UK
Since using the WellO2 machine, my husband says my snoring isn’t as loud even if I'm flat on my back, which is an added bonus as we both get a peaceful sleep

Still Have Questions About Sleep and Breathing?
Can WellO2 help me if I snore?
WellO2 training combines warm steam with adjustable breathing resistance to exercise the muscles that support natural breathing. Using the WellO2 nasal mask also engages the small muscles of the nose, throat, and larynx, which play a role in keeping the airways open. Many users who snore include WellO2 in their evening routine, as the nasal mask can help open a stuffy nose and support nasal breathing before bedtime.
Is WellO2 a medical treatment for sleep apnea or other sleep disorders?
No. WellO2 is not a medical device and is not intended to diagnose, treat, or cure any medical conditions. If you suspect sleep apnea or another condition, please consult a healthcare professional.
Does WellO2 support nasal breathing?
Yes. Every device comes with a nasal mask, which allows you to direct warm steam and resistance training through the nose. This can support more comfortable nasal breathing, which is important for healthy sleep and recovery.
When should I use WellO2 if I have trouble sleeping?
Many people use WellO2 in the evening as part of their wind-down routine, as the warm steam and slower breathing exercises can feel calming. Others prefer using it during the day to support breathing fitness. You can choose the time that best fits your routine.
How quickly will I notice a difference?
Some people feel comfort from the steam and breathing exercise right away. But like any form of training, strengthening the breathing muscles takes consistency — just like going to the gym. Many users notice changes after a few weeks of regular use.
Is WellO2 safe to use every night?
Yes. WellO2 is designed for daily use. Each session takes just a few minutes, and you can adjust steam temperature and resistance to your comfort level. For the best results, we recommend training twice a day, especially during the first month, to help build a consistent routine.
Breathe Better. Sleep Deeper. Wake Refreshed.
Better nights begin with better breathing. Let WellO2 help you wind down, fall asleep, and stay asleep, naturally.
