An alarm bracelet designed to wake users with silent vibrations offers a gentler alternative to traditional alarms, according to a review in You Magazine.
Marketed to individuals who are hard of hearing or wish to avoid disturbing a partner, the bracelet aims to circumvent the body's fight-or-flight response, potentially preventing the stress hormone spikes associated with loud alarms. In addition to its wake-up function, the device also tracks sleep patterns and counts steps, similar to other wearable fitness trackers.
However, sleep scientist Dr. Dan Gartenberg cautions that a vibrating alarm is not inherently healthier than a sound alarm. He notes that both intense sound and vibration can lead to stressful awakenings if their intensity is too high or begins abruptly. Dr. Gartenberg suggests that a combination of sound, light, and vibration may be the most effective approach for a healthy awakening.
The reviewer found that waking up to the bracelet's vibrations felt calmer than using a conventional alarm. Yet, after wearing it for five nights, doubts arose about its ability to rouse a deep sleeper, particularly as the vibrations subside after 40 seconds.
