The optional apnea walk is for short walking holds only with a reliable spotter on a flat, open route away from water, traffic, stairs, and obstacles. Never use Tidehold in water, while driving, near hazards, or anywhere a loss of consciousness could cause injury. Stop if you feel unwell. Tidehold provides training structure, not medical advice, diagnosis, treatment, or emergency monitoring.
