The Pulsetto FIT is a wellness device that works by sending gentle electrical pulses to the vagus nerve, which drives the body's parasympathetic nervous system. The device is designed to help govern the body's 'rest and digest' functions, like recovering after a workout or calming down after a stressful event. The author tried the Pulsetto and found it had an immediate calming and relaxing effect.
