Health note
The guides here are general information about everyday stress, relaxation and sleep, not medical advice, diagnosis or treatment. Breathing exercises can cause dizziness in some people; stop and breathe normally if that happens. If you are pregnant or have a heart or lung condition, check long breath holds with your clinician first.
