Dodow Review: How the Sleep Light Works, What the Evidence Says and Who It Helps

Our verdict

Yes, if racing thoughts keep you awake at bedtime or after waking in the night, and you want a simple, drug-free way to slow down. Dodow review in one line: a small, well-made light that paces your breathing to about six breaths a minute, from a French company with strong owner ratings and a 100-day guarantee. It scores 7.2 out of 10, among the higher scores on the site. It is held back by marketing claims that go beyond the research, a price no lower than the maker's own store, and free alternatives that teach the same technique.

The short version

• A palm-sized disc that projects a pulsing blue halo onto your ceiling; you breathe in as it grows and out as it shrinks.
• Tap once for 8 minutes or twice for 20; it switches off by itself. Runs on AAA batteries.
• $59 for one on 3 October 2026, $88.50 for two, $118 for three. Livlab's US store listed it at $58.
• 100-day money-back guarantee on the offer page.
• Best trait: an easy, screen-free way to practise slow breathing in bed.
• Biggest drawback: it is a relaxation aid, not a treatment, and the headline claims overreach.
• Our score: 7.2 out of 10.

Pros & cons

Dodow is one of the better products sold through offer pages: an established brand, a real technique behind it and happy owners. The main things to weigh are the marketing language and whether you would rather use a free app.

How it works

Dodow is a breathing guide. It does not emit sound, use an app or track your sleep.

1. 01

   Tap to start a cycle

   Step 1: Place Dodow on your nightstand and tap its touch-sensitive top once for an 8-minute session or twice for 20 minutes. You can adjust the brightness of the light by touch.

2. 02

   Breathe with the halo

   Step 2: Dodow projects a soft blue halo onto the ceiling that slowly grows and shrinks. You breathe in as it grows and out as it shrinks, and the rhythm gradually slows to about six breaths a minute.

3. 03

   Let your mind follow the light

   Step 3: Following the light gives a racing mind something simple to focus on, and slow breathing helps the body relax. When the cycle ends, the light switches off on its own.

The technique is often called slow-paced breathing or resonance breathing. Breathing at around six breaths a minute, with a longer out-breath, tends to increase the activity of the parasympathetic "rest and digest" side of the nervous system. Following a light also crowds out the looping thoughts that keep many people awake.

Who it's for

Dodow suits people who lie in bed with their mind racing: replaying the day, planning tomorrow, worrying. It suits people who wake at 3am and struggle to drift off again, travellers adjusting to a new time zone, and anyone who would like to stop reaching for a phone or a sleeping pill at bedtime.

It is not a substitute for medical help if you have long-term insomnia, and it will not help much if pain, a snoring partner, a noisy room or sleep apnoea is what keeps you awake.

Why Dodow appeals

Breathing exercises are one of the most common pieces of sleep advice, but they are hard to do when you are tired and your mind keeps wandering. Counting breaths needs effort; apps need a bright screen. Dodow takes the counting away: you just follow a slow, soft light.

It is also simple. There are no settings beyond two cycle lengths and brightness, no subscription and no Bluetooth to pair. It is small enough to pack for a trip.

What a typical night looks like

You get into bed, turn off the main light and tap Dodow. A soft blue circle appears on the ceiling and slowly swells and fades. For the first minute or two you breathe a little faster than you might like, then the rhythm gradually slows. Your attention settles on the light rather than tomorrow's meeting. Many owners say they drift off before the cycle ends; if not, the light fades out and you are left in a dark, quiet room, usually calmer than when you started.

That is the whole experience. It is simple, and its simplicity is the point.

Who gets the most value

People who use it nightly for a few weeks, as a wind-down habit, get the most from it. Owners who report the best results often describe their minds settling within a few minutes of watching the light. People who already fall asleep easily, or who only struggle occasionally, may find a free breathing exercise is enough.

As a gift

Dodow is a popular gift, and one of the page's testimonials describes buying it for a parent. It is suitable from age 6, according to the page, so it can work for older children who struggle to settle, with an adult helping at first.

• People whose racing thoughts keep them awake when they first get into bed
• Anyone who wakes in the night and struggles to drift off again
• Travellers fighting jet lag, and people who want a drug-free wind-down routine

Who should skip it

• Anyone with long-term insomnia that has not been assessed by a doctor
• People whose sleep is disrupted by pain, snoring, sleep apnoea or a medical condition
• Sleepers who share a room with someone bothered by any light
• People happy to use a free breathing app or exercise

How much does Dodow cost, and what do you get?

Dodow cost $59 for one on the offer page on 3 October 2026, with two for $88.50 and three for $118 including free shipping, while Livlab's own US store listed it at $58. You get a small light metronome that projects a soft blue halo onto the ceiling, slowing your breathing to about six breaths a minute over 8 or 20-minute cycles. It runs on three AAA batteries and has a 100-day guarantee.

You get the Dodow unit. Livlab's product images show three AAA batteries under a lid in the base, an LED on top that projects the halo, and a touch-sensitive surface.

Specifications

Dodow price and bundles

On 3 October 2026 the offer page our link opens showed:

The page advertises "33% off", based on its multi-pack savings. Livlab's own US store listed Dodow at $58 the same day, and its French store lists it in euros. The store also sells a travel case and a lifetime warranty add-on.

What is not included

The offer page does not list a travel case, and there is no app or subscription. Livlab sells a travel case and a lifetime warranty separately in its own store. Check the box contents at checkout if batteries matter to you, and keep a few AAA batteries in the drawer.

What this means for you: one Dodow costs about the same here as at the maker's own store. The multi-packs make sense only if you want one for another bedroom or as gifts.

Is $59 good value?

For a well-made device with no ongoing costs, from an established maker with a long guarantee, $59 is reasonable. It is more than a free app, and less than most other sleep gadgets, such as sound machines with apps, sleep headbands or smart lights. You are paying for convenience: a guide you can follow without a screen.

Who makes it

Dodow is designed by Livlab, a French company that says it has made Dodow since 2012. Livlab's store also sells sleep audio headbands and a children's audio storyteller. The offer page says Dodow is made in France and distributed locally in the US; Livlab's own description says it is designed in France.

The offer page our link opens is run by a marketing partner that sells Dodow in the US alongside Livlab's own store.

Does Dodow work, and what does the evidence say?

Dodow guides a well-studied technique: slow, paced breathing at around six breaths a minute, which supports relaxation. A small 2015 study in Psychophysiology found people with insomnia fell asleep faster after practising paced breathing. There is no published trial of Dodow itself, so its benefit rests on the technique, a calming routine and strong owner ratings rather than direct proof.

Nobody on our team has used Dodow. This section is based on published research into slow breathing, Livlab's own claims, a hands-on review and owner feedback.

The technique has some support

Slow, paced breathing at around six breaths a minute is well studied for relaxation and heart rate variability. A small 2015 study in Psychophysiology, Efficacy of paced breathing for insomnia, compared 14 people with insomnia and 14 good sleepers. When the insomniacs practised slow, paced breathing for 20 minutes before bed, they fell asleep faster, woke less and slept more efficiently.

That is a useful signal, but it is one small study, not proof that a light device helps everyone.

There is no published trial of Dodow itself

We found no independent, published, controlled trial of Dodow. The "2.5x faster" figure appears in Livlab's marketing; we could not find a published study behind it, and it may come from customer surveys. "Inspired by 13,000 sleep studies" refers to research on the technique in general, not to tests of the device.

Why it may help even without a trial

Two plausible mechanisms work together. Slow breathing with a longer exhale encourages physical relaxation. And watching a slow, repetitive light occupies your attention, leaving less room for worry. Both are part of recognised relaxation techniques used alongside cognitive behavioural therapy for insomnia.

How slow breathing affects the body

At rest, most adults breathe around 12 to 20 times a minute. Slowing to about six breaths a minute, with a longer out-breath, tends to lower heart rate slightly and increase heart rate variability, a marker of the body shifting toward a relaxed state. People often describe feeling heavier and calmer within a few minutes. None of this forces sleep, but it removes some of the physical tension that keeps people awake.

Expectation and routine matter too

Part of any sleep aid's effect comes from expectation and from the routine itself. Doing the same calming thing every night signals to your brain that it is time to sleep. That is not a reason to dismiss Dodow; it is a reason to use it consistently, as part of a wind-down routine, rather than only on bad nights.

What a hands-on reviewer found

A detailed hands-on review on WeTriedIt reported getting sleepy quickly and often falling asleep before the cycle finished, and found it useful for falling back asleep in the night. The reviewers did raise a question about using blue light at bedtime.

What about the blue light?

Bright blue light in the evening can delay the body clock, which is why screens before bed are discouraged. Dodow's light is dim, projected onto the ceiling rather than into your eyes, adjustable and on for only 8 or 20 minutes. Many people follow it with their eyes half closed. We are not aware of evidence that this small dose meaningfully affects sleep timing, but if you are sensitive, keep the brightness low.

Realistic expectations

Expect Dodow to help you settle and relax, especially on nights when your mind is busy. It may take a few nights to get used to breathing with the light. Expect less from it if your sleep problem is mainly about waking very early, sleeping at the wrong time of day, pain, or a medical condition.

Are Dodow's claims true?

Dodow's core idea is sound, but its headline claims go beyond the research. We could not find a published study behind "fall asleep 2.5x faster", and "scientifically proven" is too strong for the device itself, though "inspired by" sleep research is fair. The endorsement from sleep psychologist Dr Michael Breus is an endorsement, not a trial. It is drug-free, as claimed.

"Fall asleep 2.5x faster"

We could not find a published study behind this figure. Slow breathing may help you fall asleep faster, but the size of the effect will vary a great deal between people.

"Scientifically proven" and "inspired by 13,000 sleep studies"

The technique, slow breathing and heart coherence, is widely studied. The device itself has not been independently tested in a published trial that we found. "Inspired by" is accurate; "scientifically proven" is too strong for Dodow itself.

"Doctor-recommended, including Dr. Michael Breus"

The page says Dr. Michael Breus, a sleep psychologist known as "The Sleep Doctor", recommends Dodow, and search summaries describe him as acknowledging it as a supportive option. That is an endorsement, not a clinical trial.

"Retrains your brain to fall asleep on its own"

Some owners say they now fall asleep without using it. That is plausible: learning a calming routine can carry over. But it is a testimonial, not a measured result.

"Stay asleep" and "best night's sleep in years… every single night"

Dodow helps with falling asleep. There is little reason to expect it to change how deeply you sleep or prevent waking, beyond helping you drift off again when you do.

"100% natural and drug-free" and "no side effects"

Drug-free, yes. Side effects are minimal; a few people may feel light-headed if they over-breathe, and the light may disturb a bed partner.

"Combines yoga, meditation and behavioural therapy"

Slow breathing is common to yoga and meditation, and relaxation training is part of behavioural therapy for insomnia. Dodow uses one technique from that toolkit. It does not include the other parts of behavioural therapy, such as sleep scheduling or work on unhelpful thoughts about sleep.

"Made in France"

The offer page says Dodow is made in France. Livlab's own description says it is designed in France. We could not confirm where units are manufactured; the difference does not affect how it works.

"Over 1 million users"

Livlab says Dodow has more than a million users. We cannot verify the figure, but Dodow has been sold widely in Europe and the US for over a decade, and its Trustpilot profile has thousands of reviews.

Claims scorecard

Is Dodow better than a breathing app or breathing exercises?

Free breathing apps and techniques such as 4-7-8 breathing teach the same slow-breathing approach at little or no cost. Their drawback is a bright phone in bed, or a mind that wanders while counting. Dodow's advantage is guiding the rhythm with a soft light on the ceiling, without a screen, which helps people who find counting hard when anxious or tired. For chronic insomnia, CBT is the recommended treatment.

Dodow vs a free breathing app

Many free and paid apps guide slow breathing with animation or sound. They cost less, and some include sleep stories. The trade-off is a bright screen in bed and the temptation to check messages. Dodow is the better choice if you want to leave your phone out of the bedroom.

Dodow vs breathing exercises without a device

Techniques like 4-7-8 breathing or simply breathing out for longer than you breathe in cost nothing. If you can do them without your mind wandering, you may not need Dodow. Many people find counting breaths difficult when anxious or tired, which is the gap Dodow fills.

Dodow vs a sound machine

A white noise or nature sound machine masks noise and gives the mind something to rest on. It works better in noisy homes; Dodow works better for racing thoughts in a quiet room. Some people use both.

Dodow vs a sunrise or sunset lamp

Some smart lamps dim slowly at bedtime to mimic a sunset, and brighten in the morning. They help set a routine and suit people who wake groggy. They do not guide breathing. Dodow is the more direct tool for a racing mind at bedtime; a sunrise lamp is more about waking up.

Dodow vs a weighted blanket

Weighted blankets give deep, even pressure that many people find calming, and they work all night. They cost more, can be warm, and do not suit everyone. Dodow targets the first minutes of falling asleep; a weighted blanket targets comfort through the night.

Dodow vs sleeping pills

Over-the-counter sleep aids and prescription medicines work differently and have side effects, including next-day drowsiness and dependence for some types. Dodow has none of these, but it is also gentler. If you take sleep medication, do not stop it without talking to your doctor.

Dodow vs CBT for insomnia

Cognitive behavioural therapy for insomnia, available through clinicians and structured programmes, is the recommended first-line treatment for chronic insomnia. Relaxation techniques like slow breathing are often part of it. Dodow can support that work; it does not replace it.

Dodow vs other sleep products we have reviewed

Our sleep section covers other approaches, including the Chill Pill electrotherapy device, the Sleep Connection anti-snore wristband and the SleepZee mouthpiece for snoring. Our best sleep products guide compares more options. For children, our Moonbuddy review covers a screen-free breathing companion made for kids.

If you have decided guided breathing suits you, the Dodow order page (opens Dodow in a new tab) lists the single and multi-pack offers.

Is Dodow legit, and what should you check before buying?

Dodow is made by Livlab, a real French company with a Trustpilot score of 4.5 from 4,063 reviews and a 100-day money-back guarantee. Before buying, compare the offer price with Livlab's own store, which listed it at about the same price, and remember it is a relaxation aid, not a treatment. If sleep problems last more than a few weeks, talk to a doctor.

It is a relaxation aid, not a treatment

Dodow does not diagnose or treat insomnia or any medical condition.

What to do: if you have struggled with sleep for more than a few weeks, or feel very sleepy during the day, talk to a doctor. Sleep apnoea, depression, anxiety, pain and some medicines all affect sleep and need proper care.

Breathing comfort

Slow breathing should feel comfortable, not forced.

What to do: if you feel light-headed, short of breath or anxious following the light, breathe normally and stop. If you have a lung or heart condition, ask your doctor whether slow breathing exercises suit you.

Light and bed partners

The halo is dim but visible on the ceiling.

What to do: if your partner is sensitive to light, turn the brightness down or try it on nights when you sleep alone first. A 20-minute cycle may be more than you need; start with 8.

Pregnancy, children and older adults

Slow breathing is generally gentle, and the device emits only light. The page says Dodow is suitable from the age of 6.

What to do: for children, use it with an adult at first. If you are pregnant or have a health condition that affects breathing, follow your doctor's guidance on breathing exercises. Older adults with persistent sleep problems should have them checked, as they can have medical causes.

Light sensitivity and migraines

Some people find any light uncomfortable at night, particularly those prone to migraines.

What to do: turn the brightness right down, or try following the glow with your eyes closed. If the light bothers you, a sound-based breathing guide may suit you better.

Price and bundles

One Dodow costs about the same on the offer page as in Livlab's US store.

What to do: buy one unless you want extras for other bedrooms or gifts. Check whether shipping is added to the single unit at checkout.

Returns

The offer page promises a 100-day money-back guarantee.

What to do: use it nightly for at least two weeks before judging it. Keep your order confirmation and packaging, and note the date so you can return it inside 100 days if it has not helped.

Customer service

Some Trustpilot reviewers report slow replies, warranty registration problems and devices that stopped working.

What to do: register any warranty promptly, keep emails in writing, and test the device as soon as it arrives.

Batteries

Dodow runs on AAA batteries.

What to do: keep spares in the drawer. Rechargeable AAA batteries cut cost and waste.

How to buy Dodow the smart way

1. Decide whether you want a device or would rather try a free breathing exercise first, then open the Dodow offer page (opens Dodow in a new tab).
2. Pick one unless you need more for other rooms or gifts.
3. Check the total and shipping before paying.
4. Decline any add-ons you did not plan to buy.
5. Keep your order confirmation and note the 100-day return date.
6. Use it every night for two weeks before deciding.
7. If it has not helped by then, start the return within the guarantee.

What do owners say, and how did we score Dodow?

Dodow scores 7.2 out of 10: claim accuracy 1.1, build durability 1.4, price competitiveness 1.4, usability 1.7 and owner satisfaction 1.6, each out of 2. Livlab's Trustpilot profile showed 4.5 from 4,063 reviews, with 68% five-star and 28% four-star. Owners praise better sleep and ease of use; complaints mention slow support replies, warranty registration problems and devices that stopped working.

Trustpilot

On 3 October 2026 the Trustpilot profile for Livlab, Dodow's maker, showed a TrustScore of 4.5 out of 5 from 4,063 reviews: 68% five-star and 28% four-star, with very few low ratings. The profile covers Livlab's products generally, with Dodow its best known.

Owners praise improved sleep, ease of use and helpful support staff. Complaints mention slow customer service replies, problems registering warranties, refund errors on shipping, and devices that stopped working. Trustpilot showed Livlab replying to about 29% of negative reviews, usually after more than a month.

The testimonials on the page

The offer page shows four five-star testimonials from verified buyers. They describe falling asleep faster, getting back to sleep in the night, and using it in place of a sleeping aid. One mentions a fitness tracker showing they fell asleep within about 10 minutes.

What the reviews agree on

The most consistent praise is about calming a busy mind at bedtime. The consistent caveat, from owners and reviewers alike, is that it takes a few nights to get used to, and that it helps some people much more than others.

Who it seems to work for

Reading owner feedback, the strongest results come from people whose main problem is a busy mind at bedtime, people who wake in the night and cannot settle, and travellers. Weaker results tend to come from people with long-standing insomnia, shift workers, and people whose sleep is broken by pain, noise or a partner's snoring. That matches what you would expect from a relaxation aid.

Common complaints, in context

Most complaints on Trustpilot are about service rather than the idea: slow replies, warranty registration problems, refund mistakes on shipping, and units that stopped working. A smaller group say it simply did not help them. If you buy, keep your paperwork, test it promptly, and use the guarantee if it is not for you.

Why ratings are so positive

Dodow is a one-time purchase with a long guarantee, sold mostly to people actively looking for help with sleep. People who find it helpful tend to keep it and leave good reviews; those who do not may simply return it. The ratings tell you many people like it, not that it works for everyone.

What we would test with a Dodow in hand

If we test it ourselves, we will use it nightly for several weeks with a sleep tracker, compare time to fall asleep with and without it, try both cycle lengths, measure the light at pillow height, and test how well it works after waking in the night. We will update this review with the results.

How we scored Dodow

Every score on the site follows the five criteria on our how we test page.

The score would rise with a published, independent trial of the device and marketing that matches the evidence.

What we did, and did not, do

We read the offer page, Livlab's store listing, the Trustpilot profile, a published study of paced breathing in insomnia and a hands-on review, all on 3 October 2026. Nobody on our team has used Dodow, and no figures here come from our own testing.

How to use Dodow for the best results

Put Dodow on your nightstand pointing up so the halo lands on the ceiling, and lie on your back. Tap once for an 8-minute cycle or twice for 20 minutes, and adjust the brightness so it is soft. Breathe in as the halo grows and out as it shrinks, gently rather than deeply. If you wake in the night, tap it again instead of checking your phone.

  Dodow in a dark bedroom

1. Put Dodow on your nightstand, pointing up, so the halo lands on the ceiling above you.
2. Get comfortable in bed, lying on your back to start.
3. Tap once for an 8-minute cycle, or twice for 20 minutes if you take longer to settle.
4. Adjust the brightness by touch so it is soft, not bright.
5. Breathe in as the halo grows and out as it shrinks, without forcing your breath.
6. Let your eyes half close and follow the light; turn on your side when you feel sleepy.
7. Use it every night for at least two weeks to build the habit.

Getting the rhythm right

At first the light moves faster, then slows. Do not try to breathe deeply; breathe gently and let the pace slow with the light. If you lose the rhythm, simply pick it up on the next cycle.

If you wake in the night

Tap Dodow again for an 8-minute cycle rather than checking your phone or the clock. Many owners say this is where it helps most.

Pairing Dodow with other habits

• Caffeine: stop caffeine by early afternoon; it lingers for hours.
• Alcohol: it may make you drowsy, but it fragments sleep later in the night.
• Light: dim the lights an hour before bed, and get daylight in the morning to set your body clock.
• Regular times: going to bed and getting up at the same time every day, weekends included, is one of the most effective sleep habits.
• Bedroom: keep it cool, dark and quiet, and keep work and screens out of bed.

Dodow can help you relax once you are in bed, but these habits decide how easily sleep comes in the first place.

Keeping a simple sleep diary

For two weeks, note roughly when you went to bed, how long it took to fall asleep, whether you used Dodow and how you felt the next day. It helps you judge whether Dodow is working before the 100-day guarantee ends, and it is useful to show a doctor if problems continue.

Build a wind-down routine

Dodow works best as the last step of a routine: dim lights an hour before bed, put screens away, keep the bedroom cool and dark, and go to bed at a regular time. Light, slow breathing at the end of that routine is much more effective than on its own.

Travelling with Dodow

It is cordless and small, so it travels easily. In a hotel, aim it at a pale ceiling; a dark ceiling makes the halo harder to see. It can help on the first nights in a new time zone.

Pack it in a soft pouch or the travel case so the touch surface is not pressed in your bag, which could start a cycle and drain the batteries. Bring spare batteries on long trips.

Using it with children

For children aged 6 and up, sit with them for the first few sessions and breathe together with the light. Use the 8-minute cycle and keep it part of a calm bedtime routine.

If you share a bed

Agree on it first. Many partners find the dim light unobtrusive, especially on the 8-minute cycle. If your partner is sensitive, position Dodow on your side, aim it at the ceiling above you, and keep the brightness low.

When to stop using it

If you notice you now fall asleep easily without it, you do not need to keep using it every night. Keep it for nights when your mind is busy, or for travel.

What else do people ask about falling asleep?

Most questions are about why sleep will not come. A busy, alert mind can keep you awake even when your body is tired, and stress, caffeine, alcohol, screens and irregular sleep times all play a part. Most healthy adults fall asleep within about 10 to 20 minutes; regularly taking more than 30 is worth addressing. Slow, paced breathing can help as part of a wind-down routine.

Why can't I fall asleep even when I'm tired?

A busy, alert mind can keep you awake even when your body is tired. Stress, worry, caffeine, alcohol, screens and irregular sleep times all play a part. Relaxation techniques help with the mental side; regular routines help with the rest.

How long should it take to fall asleep?

Most healthy adults fall asleep within about 10 to 20 minutes. Regularly taking more than 30 minutes is a sign of difficulty falling asleep worth addressing, especially if it happens most nights.

Does slow breathing really help you sleep?

It can. Slow, paced breathing encourages relaxation, and a small study found people with insomnia fell asleep faster after practising it. It works best as part of a wind-down routine.

What is the 4-7-8 breathing technique?

Breathe in through your nose for a count of four, hold for seven and breathe out slowly through your mouth for eight. Like Dodow's rhythm, it slows breathing and lengthens the out-breath.

Is blue light before bed always bad?

Bright light from screens in the evening can delay the body clock and keep the mind alert. A dim, brief light like Dodow's, aimed at the ceiling, is a much smaller exposure, but keeping all lights low before bed is good practice.

What is the best treatment for chronic insomnia?

Cognitive behavioural therapy for insomnia is the recommended first treatment in most guidelines. It covers sleep habits, thoughts about sleep and relaxation techniques, and can be delivered by clinicians or structured programmes.

Should I get out of bed if I can't sleep?

Sleep experts often suggest that if you have been awake for a long time and feel frustrated, you get up, do something calm in dim light, and return to bed when sleepy. Lying awake and anxious can teach your brain to link the bed with wakefulness.

Can I use Dodow every night?

Yes. It is designed for nightly use, and there are no known risks to using it every night. Some owners find they need it less over time.

Can I use Dodow for naps?

You can. A short 8-minute cycle can help you relax for a daytime nap, though the halo is harder to see in a bright room. Draw the curtains for best results.

How long do the batteries last?

Livlab does not give a figure on the offer page. Hands-on reviewers report batteries lasting months of nightly use, as the device draws little power and runs only for short cycles.

Is Dodow worth it compared with an app?

If you are happy to use your phone in bed and can resist checking it, a free breathing app does a similar job. If you want your phone out of reach, or find screens keep you awake, Dodow's simple light is worth the one-off cost for many people.

Can Dodow help with anxiety?

Slow breathing is a common technique for calming anxiety, and some owners say Dodow helps them unwind. It is not a treatment for anxiety disorders; if anxiety affects your daily life, talk to a doctor.

Do sleep gadgets actually help?

Some do, for some people, especially those that support good habits like relaxation, darkness and quiet. Be wary of gadgets claiming to cure insomnia. The most reliable improvements come from consistent sleep habits and, for chronic insomnia, proper treatment.
