A vibrating alarm bracelet is being tested as a less aggressive alternative to traditional sound alarms, particularly for those who are hard of hearing or wish to avoid disturbing a sleeping partner. Marketed as a gentler way to wake up, the band aims to prevent the stress response and cortisol spikes associated with sudden, loud alarms.
Beyond its alarm function, the bracelet also tracks sleep patterns and counts steps, similar to fitness trackers. The premise is that its silent, gentle vibrations will offer a calmer awakening experience.
However, sleep scientist Dr. Dan Gartenberg suggests that the effectiveness of a vibrating alarm is not inherently superior to a sound alarm. He posits that both sound and vibration can be stressful if too intense or abruptly activated. Dr. Gartenberg recommends a combined approach of sound, light, and vibration for optimal awakening.
In a five-night trial, the bracelet’s vibrations were noted as being calmer than a standard alarm. Yet, questions remain about its ability to rouse deep sleepers, especially since the vibrations diminish after 40 seconds. The thin design, intended to be unobtrusive, means the wearer may barely notice it.
