The B-Pulse from Bumble BLS works by sending gentle vibrations back and forth between two small units that you can hold in your hands, mount on watchbands or tuck in our plush kid-friendly cases. This gentle side-to-side sensation helps to mediate the body’s stress response while promoting calm and focus. B-Pulse is optimized for both EMDR and Play Therapy, and can even be used preventatively during times of stress.
