Guided Breathing Exercises
Box breathing, 4-7-8, and the physiological sigh — three well-documented techniques, one guided timer
Controlled breathing patterns are a well-documented, widely taught technique for engaging the body's parasympathetic ('rest and digest') nervous system response, commonly used for short-term stress and focus regulation. Spirio guides three specific, named patterns rather than a generic 'breathe deeply' prompt: Box Breathing (4-4-4-4, equal-length inhale, hold, exhale, hold), popularized in part through use by military and tactical training programs for staying calm under pressure; 4-7-8 (a longer exhale than inhale), a technique associated with Dr. Andrew Weil; and the physiological sigh (a double inhale followed by a long exhale), a pattern that has drawn recent attention from respiratory physiology research, including work summarized by Stanford's Huberman Lab, as an especially fast way to reduce physiological stress markers.

Frequently asked questions
What is box breathing?
A pattern of four equal-length phases: inhale for a count (commonly 4 seconds), hold, exhale for the same count, hold again, then repeat. It's simple enough to do without counting on your fingers and is commonly taught in military, first-responder, and athletic training contexts as a way to stay composed under acute stress.
What is 4-7-8 breathing?
A pattern with a 4-second inhale, a 7-second hold, and an 8-second exhale — deliberately weighted toward a long, slow exhale, which is associated with engaging the parasympathetic nervous system's calming response. It's commonly recommended as a technique for winding down before sleep.
What is the physiological sigh?
A double inhale (one full breath in, then a second short inhale on top of it) followed by a long, slow exhale. It mimics a breathing pattern the body does naturally during sleep and crying to reinflate collapsed air sacs in the lungs, and has been highlighted in respiratory physiology research as an unusually fast way to lower stress-related physiological markers compared to other breathing techniques.
Can breathing exercises replace treatment for anxiety?
No — they're a general self-regulation technique, not a treatment. They can help with short-term stress or acute anxious moments, but they're not a substitute for professional care when anxiety is persistent, severe, or interfering with daily life.
