Every tool in Woosha is grounded in peer-reviewed research on how the nervous system responds to anxiety — and how it recovers.
The nervous system doesn't distinguish between a real threat and a perceived one. Woosha works with that biology — not against it.
Developed by Dr. Stephen Porges, polyvagal theory explains how the vagus nerve regulates our sense of safety. Woosha's breathing protocols are specifically designed to activate the ventral vagal state — the body's "safe and social" mode.
Porges, 1994Extended exhalation activates the parasympathetic nervous system, slowing heart rate and reducing cortisol. Our 4-4-6-2 breath protocol (inhale 4, hold 4, exhale 6, hold 2) is calibrated to maximize this effect.
Zaccaro et al., 2018Alternating left-right sensory stimulation — visual, auditory, or tactile — has been shown to reduce the emotional intensity of distressing thoughts and support nervous system regulation in research settings.
Shapiro, 1989 · Lee & Cuijpers, 2013Developed by Edmund Jacobson in the 1920s and extensively validated since, PMR works by systematically tensing and releasing muscle groups, training the body to recognize and release held tension.
Jacobson, 1929 · Manzoni et al., 2008Structured interoceptive attention — the practice of noticing internal body sensations — improves emotional regulation, reduces rumination, and increases tolerance of physical anxiety symptoms.
Kabat-Zinn, 1990 · Mehling et al., 2012Anxiety involves a systematic bias toward threat cues. Woosha's calm gaming suite includes ABMT-inspired activities that gently train attentional focus away from threat, reducing baseline anxiety over time.
MacLeod & Mathews, 2012Most people with anxiety know, intellectually, that they're safe. The problem is that the body doesn't get the message.
That's the core insight behind Woosha: cognitive understanding alone isn't enough. The nervous system needs to be met with somatic tools — breath, movement, sensory input, attention — before it will shift out of threat mode.
Every feature in Woosha is designed with this principle in mind: work with the body's own regulatory mechanisms, not around them.
"The body keeps the score. What happens in the body during anxiety must also be addressed in the body during recovery."
FOUNDATIONAL PRINCIPLE
"Slow, extended exhalation is one of the most reliably effective self-regulation tools available — and it's always accessible."
RESPIRATORY NEUROSCIENCE
"Consistent practice builds new neural pathways. What begins as effortful eventually becomes automatic."
NEUROPLASTICITY
Woosha includes 16 evidence-based lessons across 4 modules — all DSM-5-TR aligned, all written by clinicians.
