Which pattern should I use for stress?

Box breathing (4-4-4-4) is the most-studied for acute stress. Resonant (5-5) is best for ongoing anxiety reduction. 4-7-8 is the strongest sleep aid but takes practice to extend the exhale comfortably.

Is it normal to feel lightheaded?

Mild tingling or lightheadedness in the first session is common as you change your CO2 levels. If it persists, slow down — the patterns are guidelines, not commandments. Stop entirely if you have a heart condition or respiratory illness without doctor approval.

Most patterns become noticeably calming after 4–6 cycles. Daily practice for 5–10 minutes is more useful than a one-time long session. Discontinue if you feel lightheaded.
