The technique Navy SEALs use to stay calm under fire. Balanced 4-4-4 rhythm that stabilizes your mind when pressure hits. - Whale โ 4-7-8 breathing, developed by Dr. Andrew Weil. Activates your vagus nerve and drops your heart rate in under a minute. - Dandelion โ Extended exhale for winding down. Shifts your nervous system from fight-or-flight to rest-and-digest. - Shredder โ Fast-paced release breathing for when you're angry, overwhelmed, or about to lose it. - French Press โ Slow morning breathing ritual. Better than coffee for waking up your brain. FEELS LIKE NOTHING ELSE Haptic feedback pulses with every inhale and exhale โ your phone literally breathes with you. No screen-watching required.
