Stanford researchers tested three breathing techniques against mindfulness meditation in 108 healthy adults over 28 days. Participants used WHOOP wristbands for physiological monitoring while practicing daily interventions remotely. Cyclic sighing (emphasizing long exhales), box breathing (equal inhale-hold-exhale-hold), and cyclic hyperventilation were compared to passive breath meditation. The study aimed to identify the most effective remote interventions for stress reduction and wellbeing improvement in healthy populations.
