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.
