Nasal breathing

Breathe through the nose by default, including during easy exercise

Making the nose the default airway during rest, sleep and low-intensity exercise, rather than defaulting to the mouth. The arguments involve nitric oxide production, humidification, and slower breathing rates; the reported effects are less dry mouth, less snoring and a calmer baseline. Easy cardio is where most people retrain it, by slowing down enough to keep the mouth shut.
