FAQ

What is a breath ratio?+

A breath ratio describes how long inhale, hold, exhale, and second hold take. For example, 1:2 means exhale is twice as long as inhale. 4-7-8 means 4s in, 7s hold, 8s out.

Which ratio should I start with?+

Beginners do well with 1:1 (equal inhale/exhale) or box breathing (4-4-4-4). 1:2 (longer exhale) calms the nervous system. 4-7-8 is for relaxation.

Is pranayama safe?+

Healthy adults usually tolerate gentle pranayama well. Skip breath retention if you are pregnant, have uncontrolled blood pressure, or any cardiovascular condition without medical clearance.

How long should I practice?+

Start with 3–5 minutes daily and build to 10–15. Stop immediately if you feel dizzy, anxious, or short of breath.
