A new device can lower stress through stimulating its wearer with a heartbeat-like rhythm. This device is worn on the wrist, and stimulates the wearer with a rhythm that is lower than the wearer’s resting heart rate. Human beings intuitively recognize a lowered heart rate with a sense of calm, and this subconsciously affects the wearer by tricking their brain into thinking that their own heart is beating slower. In tests of the device, called a dopper, participants were asked to prepare and give a speech. Those wearing the dopper reported lower stress levels, and had lower blood pressure.
