Controlled breathing may support parasympathetic activation—the 'rest and digest' response that counteracts stress.
(Zaccaro et al., 2018; Ma et al., 2017)
A steady four-part breath (4-4-4-4) that settles your nervous system and sharpens attention. Used by Navy SEALs.
A calming rhythm that lengthens the exhale to reduce arousal and ease tension—especially good for sleep.
Breathing from the diaphragm to slow heart rate and relax the body. Foundation of all breathing work.
Stay with the natural breath to train attention and reduce reactivity. Simple yet powerful.
Use a simple count to prepare for rest. Inhale 4, exhale 6, count to 20.
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 the extended exhale and breath holds may support vagal tone, which is associated with parasympathetic nervous system activation. This may help lower heart rate and reduce blood pressure.
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.
