Frequently Asked Questions

Frequently asked questions

What benefits can I expect? And how soon will I feel them?

Cove users should expect better sleep and less stress within two weeks of consistent daily use. 

Cove works by activating a skin-to-brain pathway integral to mental wellbeing. With each session, this pathway strengthens and benefits become more noticeable. So while some users feel calmer and sleep better after just one session, for others results can take a bit of time.

Is there scientific proof of these benefits?

Yes. Cove’s benefits have been validated through multiple scientific studies with over 3,500 participants.

In home use trial studies, 90% of participants reported reduced stress and improved sleep after using Cove consistently for 30 days. 

Brain scans confirm these benefits on a biological level. fMRI studies show that Cove activates and strengthens connections in the insular cortex, a brain structure critical to emotional balance. Further, EEG reveals that using Cove for 20 minutes leads to an increase in alpha waves, a type of brain activity that indicates a sense of calm and often appears during meditation.

Is it safe to use Cove?

In a series of scientific studies with over 3,500 participants, Cove was found to be safe and caused no harmful side effects.

Cove’s vibrations are gentle and do not transmit drugs, electricity, or magnetic waves into the body. The device vibrates only on the surface of the skin, allowing your brain and body to do the rest of the work, naturally.

  • COVE is powered by the first and only peer-reviewed wearable technology proven to reduce anxiety, as published in a paper in the field’s leading research publication, Frontiers in Psychiatry and Neurouromodulation: Technology at the Neural Interface

    Cove’s underlying technology (Mechanical Affective Touch Therapy), which was developed by Affect Neuro, the clinical arm of Feelmore Labs, was independently studied by researchers at Butler Hospital, affiliated with The Warren Alpert Medical School of Brown University. 

    In examining the effects of mechanical affective touch therapy (MATT) on patients with anxiety and other mood disorders, this peer-reviewed independent study found significant improvements in symptoms, and that those improvements are associated with changes in the areas of the brain related to emotional regulation.

  • In trial studies, 90% of subjects reported reduced stress and improved sleep after using Cove. Extensive EEG and MRI studies performed by Feelmore Labs and validated by world-class neuroscientists have clearly demonstrated that Cove has the ability to modulate a deep part of the brain controlling emotional response, the insula. This leads to a greater sense of calm and well-being, and less stress and anxiety, which in turn leads to better sleep.

  • The Cove device is not intended to be a substitute for professional medical advice, diagnosis or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition.

  • Cove is a wellness device and does not require FDA clearance. Nonetheless, the device has undergone rigorous scientific evaluation, which confirms that Cove safely and effectively improves sleep and reduces stress.

  • Cove membership includes a latest generation Cove device, unlimited access to Cove's patented vibration technology, and all Cove app features including biometric feedback. All memberships include a 30 day risk-free return period, after which your membership continues until its expiration date. A membership is required to use Cove.

  • If you wish to cancel your membership for a refund, you can do so at any point during the 30 day risk-free return period.

    Outside of the 30 day return period, you can cancel in the Membership Portal. Your membership remains active until the end of the commitment period, at which point you will no longer be billed. Your payments will continue as normal until the commitment period ends.

  • At the end of the commitment period, monthly memberships will automatically renew for 3 months at $19/month. Pre-paid memberships can be renewed beyond the initial commitment period via the Cove app.

  • No, Cove was not designed to be worn while sleeping. Cove is worn before bedtime.  It will greatly help with sleep as its effects last for hours after a session and build up over time.

  • In designing Cove, we did not target particular sleep phases, but instead sought to improve overall sleep quality. Cove achieves this by activating a brain system known as the interoceptive pathway, which monitors the body’s internal state and is deeply entangled with sleep. Use of Cove before bedtime enhances interoception and, in doing so, enhances sleep. 

    Rather than rely solely on wearable trackers, our researchers evaluated sleep using a survey known as the Pittsburgh Sleep Quality Index, or PSQI. A commonly used tool, the PQSI consists of 19 questions that evaluate diverse aspects of sleep. Results from these surveys revealed that 86% of Cove users experienced considerable improvements in sleep after using the device for 20 minutes per night, every night for a month. Additionally, 77% of users reported falling asleep faster and 68% reported a reduction in daytime drowsiness. Finally, we found that users’ nightly sleep time increased by an average 65 minutes. 

    Users who monitor their sleep with fitness trackers should be skeptical of REM insights offered by these devices. Wearable trackers typically measure sleep by monitoring changes in blood flow, a process called photoplethysmography. Though this technique may be able to discern whether a person is asleep, it cannot distinguish between different sleep stages. Currently, REM data can be acquired only through polysomnography, a more sophisticated type of sleep study.

  • Cove does not directly interact with heart rate and related metrics, such as heart rate variability (HRV). By delivering gentle vibrations to the skin, our patented technology activates the brain’s interoceptive pathway, which, when functioning optimally, promotes feelings of calm and wellbeing. As such, the best way to quantify the benefits of Cove is through the use of brain imaging technologies, such as EEG and fMRI. In studies using these tools, our researchers found that Cove users experience heightened activity in the interoceptive pathway–a response consistent with enhanced relaxation.
