Why Breathing Techniques Work
When you're anxious, your breathing becomes shallow and rapid—signaling danger to your brain. Controlled breathing interrupts this pattern by deliberately slowing your breath rate.
Research suggests slow breathing, especially with a longer out-breath, may raise heart rate variability, a marker tied to the vagus nerve. This may help lower heart rate.
A 2018 systematic review (Zaccaro et al.) found that slow breathing techniques (6-10 breaths/minute) enhance autonomic, cerebral, and psychological flexibility. A 2023 study (Balban et al.) found that brief structured breathing practices were associated with improved mood and reduced physiological arousal.
