Better Breathing is Your Competitive Advantage

Every movement starts with breath. But when your breathing can’t keep up with your body, performance suffers, whether you're sprinting, lifting, or simply pushing through fatigue. Breathing fatigue, poor recovery, or shallow breathing can hold you back, no matter how well you train.

Still Have Questions?

How often should I use it?

For the best experience, we recommend using WellO2 regularly every day during your first month, for example in the morning and evening. Aim to use the device at least once a day. After the first month, you can continue with a maintenance routine that suits your preferences and goals, although we recommend using WellO2 at least three times a week as part of a regular breathing exercise routine.

There is no strict upper limit to how often you can use WellO2. You can adjust the frequency of your breathing exercises according to your own comfort, training routine, and personal goals.

If you have a long-term respiratory condition or another medical condition affecting your breathing, we recommend consulting your healthcare provider before using WellO2.

Tip: Many users incorporate WellO2 into their morning or evening wellness routine, before physical activity, or as part of their post-exercise breathing routine.

Can I use it if I’ve had a respiratory illness?

WellO2 is a drug-free breathing exercise device that combines gentle breathing resistance with warm steam as part of guided breathing exercises.

Regular training helps:

  • Strengthen inspiratory and expiratory breathing muscles
  • Help open and moisturise the airways during breathing exercises
  • Encourage controlled and steady breathing patterns
  • Help maintain airway moisture
  • Support the normal function of the airway mucous membranes
  • Support nasal breathing exercises when used with the nasal mask

If you are recovering from a respiratory illness or have a long-term respiratory condition, we recommend consulting your healthcare provider before using WellO2. You can start with shorter training sessions and adjust the steam temperature and resistance to your own comfort level.

Will it help with sleep or snoring?

Many users choose to include WellO2 in their evening breathing routine before bedtime.

Using the nasal mask directs warm steam through the nasal passages during breathing exercises and encourages regular nasal breathing. Regular training also helps tone and support the nasopharyngeal muscles.

Warm steam helps maintain moisture in the airways, while regular breathing exercises can become part of a consistent evening respiratory wellness routine.

If snoring or breathing disturbances during sleep are persistent or severe, we recommend consulting your healthcare provider.
