DUSQ Community FAQ
Last updated: 26th August 2026
This is the answer of record for the most-asked questions about DUSQ. If your question isn't here, ask in the community. We'll add it.
Q1: What does DUSQ actually do - in plain language?
A: DUSQ is a behind-the-ear wearable that tracks your nervous system through the night and corrects sleep disruptions in real time, using gentle vagal and vestibular nerve stimulation. Sleep is your body's recovery window. For that to happen, your nervous system has to shift out of sympathetic (fight-or-flight) and into parasympathetic (rest and recover). Modern life keeps most people stuck in sympathetic well past bedtime. You log eight hours and still wake up drained. Sleep trackers don't fix this. They measure duration, stages, and heart rate, then score you in the morning. DUSQ works differently. It catches disruptions as they happen and corrects them in real time, using the vagus nerve, your body's main parasympathetic pathway.
Q2: Is this just another sleep tracker?
A: No. Trackers observe. DUSQ regulates. A tracker tells you what happened to your sleep last night. It can't change what happens tonight. DUSQ operates in a closed loop. It tracks sleep disturbances via EDA (electrodermal activity), a direct measure of your nervous system's activation state. When it detects a disruption, it delivers gentle vagal and vestibular nerve stimulation to push you back into deeper sleep. No preset program. No morning report. A correction as it happens.
Q3: What's the difference between DUSQ and Pulsetto, Apollo, or other VNS devices?
A: Pulsetto is neck-worn. Conductive gel, place it on the side of your neck, sit through a four to thirty-minute session. The neck is dense with muscle. A few millimeters off the spot and you're firing the sternocleidomastoid, not the vagus. Once the session ends, the device comes off. It isn't on you during sleep, which is when the body actually repairs. Apollo Neuro is a different category. Apollo doesn't stimulate the vagus nerve. It's a haptic device that delivers low-frequency vibrations to the wrist or ankle. The idea is that rhythmic calming touch reads as a safety signal to the brain. Reasonable hypothesis. The trade-off is dose: three or more hours a day, every day, for weeks. A long-term habit, not an active intervention. DUSQ sits on the mastoid region behind the ear, while you sleep. The patch goes in the same spot every night. No sticky gel required. While it's on, the device reads you continuously- pulse, skin conductance, movement. What makes it different is what happens after you fall asleep. The device keeps reading and adjusts stimulation in real time to what your nervous system is actually doing. Apollo and Pulsetto run a fixed program. DUSQ runs a program that monitors you and adapts.
Q4: How does it physically stay on during sleep? A: DUSQ attaches via a medical grade adhesive patch engineered to fit precisely behind the ear on the mastoid junction. The patch stays on throughout the night and peels off easily in the morning. Adhesives are replaced nightly. Moreover- the DUSQ app includes a patch placement feature that guides you to the correct position when you first set it up.
Q5: How long does one patch last? What does it cost to replace them?
A: DUSQ Starter pack comes with a set of 12 patches. Each patch lasts one week. It comes with seven adhesive layers. You peel and replace one layer each night. Seven nights, seven layers, one patch. The starter pack includes 12 patches: a three-month supply. Refill packs are available at $25 for three months.
Q6: What does the stimulation actually feel like? Is it like a TENS unit?
A: It's an electrical stimulation, but not the kind a TENS unit delivers. TENS units run at higher currents and target larger sensory nerves to mask pain. DUSQ runs at much lower frequencies, calibrated to specifically engage the vagal and vestibular nerves. You'll feel a light tingle behind the ear. Most users describe it as a faint buzz or soft tapping sensation.
→ Awake guided session: ~20% intensity (gentle but noticeable)
→ Asleep: 2-4% intensity in short bursts, only when your nervous system needs the correction. Low enough that it won't wake you.
That's the closed-loop part of DUSQ, it's not running the same program all night. It's adjusting the stimulation based on what your body is actually doing.
Q7: Does it work for side sleepers? Back sleepers?
A: The device is designed to stay in place across every sleep position, side included. We've tested it across all sleepers, and the adhesive patch holds through the night.
Q8: How to use just at night or during the day too?
A: DUSQ is worn from evening through to morning. It works across three stages: 1.Unwinding: Whenever you're ready to start winding down, DUSQ reads your nervous system and suggests the best time for a 20-minute stimulation session, usually 2 to 3 hours before your typical bedtime. 2.Sleep initiation: ****Right before bed, you start DUSQ's sleep mode. A 20-minute session runs at a preset intensity. Parameters can be adjusted to match how you're feeling that night. 3.Sleep maintenance: Once you're asleep, the device takes over autonomously. It monitors your autonomic signal and delivers low-intensity corrections only when it detects sympathetic surges or sleep disruptions. In the morning, peel the patch off and place it back in the charging case. DUSQ also has a separate mode for afternoon naps, power naps, and daytime regulation as well.
Q9: Is there clinical evidence? How was it tested?
A: Yes. We've completed two clinical studies. Here's what we did and what we found, in plain language.
The first study:
212 people, split into two random groups. One group used DUSQ. The other used a device that looked and felt identical but delivered no real stimulation. Neither the participants nor the researchers knew who had which until the data was analysed. This is called a sham-controlled trial. It's the gold standard for ruling out placebo effects. The study ran 14 days. Each person used the device twice a day for 20 minutes. We measured them before and after using hospital-grade equipment. It was conducted at Vasundhara Hospital, Jodhpur, registered publicly with the Clinical Trials Registry of India (CTRI/2025/07/091925), and approved by an independent ethics committee before enrolment began.
What we measured:
Heart rate variability (HRV): a standard medical measure of how well your nervous system can shift between alert mode and recovery mode. Higher HRV means your body is better at downshifting. Measured with ECG. Brain wave activity: a 10-channel EEG, the same technology used in sleep labs. We looked at alpha and theta frequencies, which together signal a calmer, more drowsy cortical state.
What we found: HRV went up 40.1% in the active group. The sham group barely moved (4.6%). Alpha brain waves went up 35.4%. Theta brain waves went up 44.6%. Both are the patterns the brain produces as it shifts from wakefulness toward sleep. A composite measure of sympathetic surge (the body being stuck in alert mode) dropped 36% in the active group, versus 5.2% in sham. Self-reported anxiety dropped 31.9% in the active group, versus 5.9% in sham. No serious adverse events in either group.
The second study:
46 people, tracked for 42 nights each. This time we measured sleep directly using polysomnography (PSG), the full sleep-lab setup that records brain waves, heart activity, breathing, and movement across the whole night. It's the reference standard for measuring sleep architecture, meaning how much time you spend in each stage of sleep and how often you wake. It was run at the DUSQ Sleep Lab in Delhi.
What we found: Deep sleep, the stage where the body does most of its physical recovery, went up 31%. HRV improved 38%, consistent with the nervous-system downshift we saw in the first trial. Night awakenings dropped 22%, meaning people stayed asleep more continuously through the night.
Together the two studies tell the same story from two angles. The first explains the mechanism: a nervous system that can finally downshift out of alert mode. The second shows the result: deeper, less broken sleep across six weeks of real use.
Q10: Does it work with sleep apnea or if I use a CPAP?
A: DUSQ isn't built for sleep apnea. Apnea is a mechanical issue, your airway collapsing or your brain not signalling the body to breathe. DUSQ works on something different, the nervous system staying stuck in stress mode overnight. If you're on a CPAP, stay on it. Talk to your sleep doctor before adding anything new. DUSQ might sit alongside it as a complement, but it isn't a replacement.
Q11: Does it work for ADHD, neurodivergent users, or people with chronic nervous system dysregulation?
A: The mechanism is relevant. DUSQ targets parasympathetic activation through vagal stimulation, the same nervous system shift that drives lower resting heart rate, deeper HRV, and overnight recovery. For someone whose autonomic baseline runs hot, including many people with ADHD and competitive athletes, tools that push the system toward parasympathetic dominance compound well. Honest disclosure: our clinical trial did not include neurodivergent participants. We don't have controlled data in ADHD, autism, or other neurodivergent populations specifically. What we do have is early-user feedback. Some of the strongest responses in early access have come from ADHD users, particularly around getting to sleep and being able to come down after a stimulating day. These reports are encouraging but anecdotal, not clinical evidence. DUSQ is not a treatment for ADHD, autism, or any neurological condition. It's a tool that supports parasympathetic recovery. If your nervous system runs hot, the mechanism aligns with the shift your body is trying to make. Individual response will vary.
