Contraindication

A health condition or circumstance that makes a practice inadvisable or requires medical approval and adaptation. Contraindications depend on the intensity and mechanics of the technique. Gentle, slow breathing has few contraindications, while intensive methods with fast breathing or long breath holds have more. Common examples include pregnancy, heart disease, epilepsy, glaucoma and some mental-health conditions. A short screening such as a safety questionnaire helps identify when to adapt a practice or check with a doctor first.
