Research into wearable devices and their effectiveness in reducing anxiety and depression is still evolving, with some promising findings but limited conclusive evidence. Several devices have shown potential based on studies, user feedback, and clinical trials, though results vary in terms of scientific rigor and long-term impact.

Apollo Neuro: This wearable, worn on the wrist or ankle, uses gentle vibrations to stimulate the vagus nerve, aiming to calm the nervous system. Studies, including one from 2019 on High Amplitude Low Frequency-Music Impulse Stimulation (HALF-MIS), suggest this type of stimulation can enhance standard depression treatments. Apollo Neuro’s makers claim it improves mental wellbeing by reducing stress, with user reports supporting its calming effects. However, peer-reviewed evidence specific to Apollo Neuro remains limited, and more robust studies are needed.

Muse Headbands (Muse 2, Muse S): These brain-sensing headbands use EEG technology to monitor brain activity and guide users through meditation exercises. Small studies and user testimonials suggest Muse can help reduce stress and improve focus, potentially easing anxiety symptoms. For example, research on EEG-based biofeedback shows it can lower anxiety scores over time, as seen in a study where participants’ Generalized Anxiety Disorder (GAD-2) scores dropped after eight weeks of use with a similar device. Muse’s effectiveness for depression is less documented, but its focus on sleep and relaxation may indirectly help.

Fitbit/Apple watch-type Devices: Widely used fitness trackers like Fitbit monitor heart rate, sleep patterns, and physical activity—factors linked to mental health. A 2021 meta-analysis found that wearables measuring physical activity (e.g., via accelerometers) correlate with lower depression rates. Studies from 2019-2020, such as one from the Health Information National Trends Survey, showed that about one-third of adults with depression or anxiety use wearables like Fitbit, with some reporting improved self-awareness and motivation. However, these devices don’t directly reduce symptoms; their benefit lies in encouraging lifestyle changes that may support mental health.

Sensate: This chest-worn device uses sound and vibration to stimulate the vagus nerve, aiming to reduce stress and anxiety. A 2022 study commissioned by Sensate reported that over 65% of participants with anxiety and 50% with depression noted symptom improvement after regular use over 3.5 months. While these findings are encouraging, the study’s brand affiliation and lack of peer review call for cautious interpretation. Users often praise its quick relaxation effects, but broader evidence is still emerging.

TouchPoints: Developed by neuropsychologist Amy Serin, these wrist-worn devices use bilateral alternating stimulation (vibrations) to alter the brain’s stress response. Early research and user feedback suggest they can reduce anxiety and stress, with potential benefits for depression. A 2021 review of wearable studies noted their effectiveness in detecting depression symptoms via physiological markers, though direct evidence of TouchPoints’ impact is largely anecdotal or from small-scale trials.

Key Takeaways and Caveats

Evidence Level: Devices like Apollo Neuro, Muse, and Sensate have shown promise in small studies or brand-led research, often reducing symptoms by 50% or more in specific cases (e.g., Feel Therapeutics’ study showed a 50% drop in depression symptoms with a similar wearable). However, many lack large-scale, peer-reviewed validation. Fitbit’s benefits are more indirect, tied to behavior tracking rather than active intervention.

Mechanisms: Most of these wearables work by either providing biofeedback (e.g., Muse, Fitbit) or stimulating the nervous system (e.g., Apollo, Sensate, TouchPoints) to promote relaxation and emotional regulation.

Limitations: Research often highlights challenges like false positives, user adherence, and the complexity of mental health, which isn’t fully captured by physiological data alone. For instance, continuous monitoring might even increase anxiety in some users if misinterpreted.

While these devices aren’t a replacement for therapy or medication, they can complement traditional approaches, especially for mild to moderate symptoms. For the most reliable results, combining wearable use with professional guidance is likely the best approach based on current knowledge.
