If you are here, poor sleep has significantly impacted your daily life
Meet DUSQ: the patented solution to sleep problems that arise from a burdened nervous system.
Fully refundable deposit
The only wearable clinically shown to deliver it.
Within 2 weeks of use. Measured across 2,000+ DUSQ users.
01The problem
Bad sleep is a nervous system problem
DUSQ moves you across that line and holds you there, all night, through its patented technology and an FDA approved modality. Without waking you.
SYMPATHETIC
Alert. Racing mind. Sleep will not start, or will not hold.
PARASYMPATHETIC
Rest and digest. Where deep sleep is actually built.
Amber is a typical night. Black is the same night on DUSQ. Every surge that crosses the dashed line is a wake up you remember, or one you do not.
02The device
Conceived in a sleep lab, by a doctor
DUSQ is a patented, clinically backed behind the ear wearable that monitors and regulates the nervous system in real time.

What is your biggest sleep problem?
Your night is breaking from surges you never feel. One of them crosses the line, and you are awake.
Why this happens
This is a sleep maintenance problem. Your sleep breaks because of brief sympathetic activation many times a night, some barely noticeable, some strong enough to fully wake you. A 3 AM wake up is usually one of these surges crossing the threshold into conscious waking. Once awake, the same racing mind pattern that blocks sleep onset can block falling back asleep.
How DUSQ was designed for it
DUSQ catches the surge on the raw signal, in real time, before it escalates into a full wake up, and delivers stimulation calibrated to that exact moment. The goal is to intervene at the micro arousal stage, before it ever becomes a conscious wake up.
DETECT/ ADAPT/ STABILISE
This is not willpower. Your body cannot make the handover from alert to rest, so it stays switched on.
Why this happens
Lying awake with a racing mind is a sympathetic nervous system problem, not a willpower problem. Falling asleep requires a shift from sympathetic activation to parasympathetic rest. If that shift does not happen, the body stays alert even when the mind wants to sleep. Melatonin and routine can help set the stage, but they do not directly lower sympathetic arousal in the moment it is happening.
How DUSQ was designed for it
DUSQ reads your readiness for sleep through the evening and suggests changes to raise it. Once you are in bed, a personalised onset session guides you down. In lab studies, subjects using the onset protocol showed measurably shorter sleep onset against the gold standard PSG record.
DETECT/ ADAPT/ STABILISE
You slept the hours. You just never got the sleep, because it was broken in ways you never noticed.
Why this happens
Waking unrested after a full night usually means sleep was fragmented invisibly. Micro arousals do not always wake you, but they interrupt the deeper restorative stages every time they occur. Enough of them across a night and the hours stop mattering. Recent research shows many sleep trackers overestimate deep sleep, because they cannot measure micro arousals at all.
How DUSQ was designed for it
DUSQ detects those arousals and stabilises them, pulling you back into deep sleep. The stimulation is gentle enough that you will never notice it, and strong enough to neutralise the sympathetic activation and protect your sleep architecture.
DETECT/ ADAPT/ STABILISE
These are not three problems. They are one nervous system showing up at three different points in the night.
Why this happens
Difficulty falling asleep, waking at 3 AM and unrefreshing sleep all trace back to a sympathetic nervous system that will not stay down long enough for parasympathetic rest to take hold, whether that is at the start of the night, the middle, or across the whole architecture of sleep.
How DUSQ was designed for it
The same closed loop runs continuously, not just at bedtime. It reads sympathetic and parasympathetic activity independently through EDA and PPG sensing all night, and stimulates the vagus and vestibular nerves whenever it detects a surge. It works on the pattern underneath all three, not on one symptom at a time.

I got diagnosed with lupus and cancer back to back in my 20s. Dealing with these destroyed my sleep.
My sleep stack bill ran into thousands of dollars and my patience ran thin. Trackers just increased my anxiety about my bad sleep. Melatonin knocked me out but never made me feel recovered.
Other vagus nerve stimulators were too uncomfortable to wear, and they only took care of one half of the problem, which was sleep onset. None acted when my sleep fragmented during the night.
That is where DUSQ begins.
06The evidence
We let the data speak for itself
Every feature ships only after it is tested against lab grade measurement in our own sleep lab.
In every chart below, the longer bar is DUSQ and the longer bar is better.

What better nights have felt like for 2,000+ people
I have stopped feeling groggy and tired each morning.
Since I had my kids 15 years ago I have not known what good sleep could be like. That, coupled with menopause, meant I could only sleep 4 hours a night at best. Then I signed up for DUSQ in May and my sleep actually started getting better.
I carry it when travelling even if I forget everything else.
I am a bodybuilder, so I am something of a biohacker. Sleep is very important for my recovery, so DUSQ and its tech made me intrigued. I bought it on a whim but it has become one of those things that has stuck with me since the first week.
A game changer for someone who carries a lot of stress.
My sleep cycle went for a toss after I made partner at my law firm. I found myself doomscrolling a lot at bedtime and just unable to sleep. I tried a lot of things and got interested in nervous system regulation at a retreat in Mexico. DUSQ came up in my research.

10Questions
Questions, answered
How does the deposit work?
The deposit is a small, fully refundable token. You can get it back any time until drop day.
It unlocks access to our private community, where we share everything: the science behind DUSQ, our research, real success stories from earlier cohorts, live manufacturing and shipping updates, and webinars and product demos. You can ask us and Dr Sid anything directly.
You only pay the locked price once you are genuinely satisfied on drop day. That is why 82% of members from earlier cohorts moved forward after seeing the science and results for themselves, with zero risk while they decided.
How long till I start seeing results?
Most users start seeing results by week 2, with increased HRV, more deep sleep and faster sleep onset.
Can I actually sleep in it comfortably?
DUSQ sits flat behind the ear. No pressure point against the pillow, no wire, nothing that shifts. We have tested it with every kind of sleeper. Most people forget they have it on.
Is there a recurring cost after purchase?
The device is a one time purchase. Your DUSQ ships with 12 reusable sleep links, the adhesive patches worn behind the ear. Each lasts about a week of nightly use, so you are covered for roughly the first 3 months out of the box. After that, refills are $25 for a set of 12, another 3 months or so. That works out to under $8.50 a month, or about 28 cents a night.
The DUSQ app is included free for the first year for early adopters. After year one it moves to a standard subscription, and we will share pricing well in advance so you can decide whether to continue.
Can I use it with a CPAP or noise cancelling earbuds?
DUSQ is not a solution for sleep apnea, because that is a mechanical airway problem rather than a nervous system one. You can, however, use it alongside your CPAP machine, and DUSQ will not interfere with any earbuds you use.
