1 Min Sigh Timer
Rapid nervous system reset with the sigh breath
The physiological sigh is nature's built-in rapid reset button — a double inhale followed by a prolonged exhale that immediately reduces CO2 and activates your parasympathetic nervous system. One minute of repeated sigh breaths (approximately 12-15 cycles) produces some of the fastest anxiety reduction of any breathing technique, often within 30-60 seconds.
Unlike paced breathing techniques that take 2-3 minutes to show effect, the sigh breath works almost instantly because it directly targets the CO2-oxygen balance that drives autonomic state. Each sigh cycle sends a powerful vagal signal that shifts you from sympathetic (fight-or-flight) to parasympathetic (rest-and-digest) within heartbeats.
The 1-minute sigh timer is perfect for acute anxiety moments: before a difficult conversation, when you notice panic rising, or any situation where you need immediate nervous system downregulation. The double-inhale pattern feels more natural than counting breaths and requires no memorization.

Frequently Asked Questions
Why does the sigh work so fast?
The double inhale followed by extended exhale directly reduces alveolar CO2, which immediately triggers parasympathetic activation through chemoreceptor signals. This is one of the most direct neural pathways to nervous system regulation.
Can I do sigh breaths for longer than 1 minute?
Yes, many people do 2-5 minute sigh breathing sessions. However, the most dramatic effect happens in the first 1-2 minutes. You can do multiple 1-minute sessions throughout the day as needed.
Is the double inhale necessary?
Yes. The double inhale (two quick inhales through the nose before a long exhale) is what makes the sigh breath unique and effective. The second inhale recruits more alveolar surface area and further reduces CO2 load.
