World Sleep Day: The 12 products we swear by for a great night's sleep when you're facing insomnia, hot flashes, and more

This sunrise alarm clock is our favorite Hatch dupe because it costs a fraction of the price whilst boasting a decent selection of light and sound features to help you wind down and wake up. It also sports a chic, phone-free design so you can resist the urge to doomscroll in bed. The sound library is basic, and there's no Bluetooth connectivity, but for under $60, it's a fantastic value — and there's no subscription needed, either.

"A true water baby, I personally enjoy the sound of crazing waves and find the Dreamegg's wave sound has helped me relax at bedtime on several occasions. I even like to play it on a low volume in the background while reading before bed." — Eve Davies, Sleep Tech Product Tester

Our Dreamegg Sunrise Alarm Clock review score: ★★★★

These are the best sleep headphones you can buy right now, as they deliver the perfect balance of features and comfort. These petite buds sit flush in your ears and come with multiple sizes of silicone ear tips for the right fit. Sound quality is very good, and with ANC and snore masking, you can effectively block those disruptive noises from ruining your sleep. Although these earbuds are made exclusively for bedtime, they're suitable for daily use, too — but keep in mind that the battery life isn't the greatest, especially with ANC activated. (They'll last about nine hours, but the case packs another 45 hours of charge.)

"[These] are some of the most comfortable sleep earbuds I’ve tested. The flush, low-profile fit is a gift for side sleepers, and the adaptive snore-masking along with solid ANC make a real difference if you’re sick of having your sleep interrupted by a snoring partner or ambient night noise." — Becca Caddy, Technology Writer

Our Soundcore Sleep A30 Earbuds review score: ★★★★

White noise can help you sleep, yet this tiny sound machine has a rainbow's worth of frequencies to help you doze off, along with fan and ocean sounds if those are more your speed. Better yet, you don't need a phone to set up or control it, allowing you to resist the urge to keep your devices out of your bedroom. And if you travel often, it's small enough to pack in a carry-on and set on a nightstand — no need to worry about noisy hotel neighbors or falling asleep in a loud city. It may not be on sale, but for an effective way to block out unpleasant nighttime sounds, it's worth paying full price.

"With so many options (22) to choose from, you will definitely find the sound that's right for your sleep or relaxation. Plus, you can leave it on all night or set it on a timer so it can gently switch off while you sleep." — Frances Daniels, Senior Sleep Writer

Our top-rated hybrid mattress comes in three firmness levels and two height options so you can tailor it to your comfort and bedroom space. It boasts best-in-class pressure relief for aches and pains, provides outstanding lumbar support, and effectively wicks away heat and moisture. This handcrafted mattress is absolutely gorgeous and wouldn't look out of place in a 5-star suite. The extras are just as attractive with a one-year sleep trial, a lifetime warranty, and free white glove delivery with mattress and foundation removal. All sizes of the Saatva Classic are $400 off with our sale link.

"I clocked up over 1,500 hours of sleep on our luxury firm review model during a seven-month period, and would agree with Saatva's claim that it offers an experience akin to sleeping on a luxury hotel mattress...I commented to my husband that I hadn't slept that well since I was a teenager." — Claire Davies, Certified Sleep Science Coach

Our Saatva Classic Mattress review score: ★★★★★

Level up your existing bed with this tri-zoned foam mattress topper from Helix. It's firmer in the middle to support the back and hips and softer everywhere else to cushion the joints. The GlacioTex cover (whilst a tad slippery) is soothing to the touch and does a standup job of dispersing heat so you're not waking up in a pool of sweat. No worries if you're a fidgety sleeper, either, as the elastic anchors keep this topper in place throughout the night. Remember to use coupon code TOMS27 to receive 27% off for World Sleep Day. It comes with a 120-night trial and a 1-year warranty.

"I placed the Helix ErgoAlign Mattress Topper on my 7" guest room mattress, which has lost a lot of its support over the last decade...the improvement in comfort and support after adding the topper was so pronounced that my thin spare bed felt like an entirely new mattress." — Alison Barretta, Mattress Tester & Sleep Writer

Our Helix ErgoAlign Mattress Topper review score: ★★★★½

The best pillow for most sleepers is one you can fully customize. The Coop Original Adjustable Pillow has an adjustable loft so you can make it as tall or flat as you need it. It comes with a spare 1/2lb bag of memory foam and microfiber fill — and if you need help setting it up, you can avail of a free 30-minute consultation with one of Coop's pillow experts. (You'll also get 100 days to trial it at home, along with a 5-year warranty.) Beyond the standard shape, a crescent option is available for combination sleepers, while a cut-out version supports side sleepers. For World Sleep Day, Coop is cutting 20% off its top-selling pillow.

"[It] was my first time trying out an adjustable pillow, and I was a little skeptical about whether it would be right for me. To my surprise, the Coop Original Adjustable Pillow felt perfectly plush, yet supportive. So much so that I decided not to adjust the fill at all." — Becky George, Sleep Staff Writer

Our Coop Sleep Goods Adjustable Pillow review score: ★★★★½

Hot sleepers are drawn to this cooling mattress for its specialist heat-conducting materials: copper-infused foam and Phase Change Material (PCM). The upgraded cover incorporates Celliant fibers, which are said to aid with recovery by absorbing body heat and converting it into infrared energy. On top of that, this premium hybrid comes in three comfort levels (Soft, Medium, or Firm) so you can tailor it to your sleep needs. Use our exclusive code TOMS35 to knock 35% off all sizes of the Bear Elite Hybrid for World Sleep Day. It comes with a 120-night trial and a lifetime warranty.

"While it's hard to verify Bear's claim that the Celliant-infused design transfers body heat into infrared energy to boost muscle recovery, I can vouch that I slept soundly while testing the Bear Elite Mattress and felt great on my runs...[it] does a first-class job of wicking heat away throughout the night." — Eve Davies, Sleep Tech Product Tester

Our Bear Elite Hybrid Mattress review score: ★★★★

Tempur Material is renowned for its superb pressure relief, but it's also notorious for trapping heat. A breathable, cool-to-the-touch cover helps counteract this, preventing heat buildup so you can rest comfortably on this premium memory foam mattress topper. The cover is removable and machine-washable for an easy maintenance, and corner straps keep the topper in place if you're one to fidget about in your sleep (although that may be less of an issue once you add it to your bed). Tempur-Pedic cuts up to 30% off its mattress toppers for World Sleep Day — just know that this item is final sale and can't be returned.

"Night sweats were a regular issue for me when I slept on the Tempur-Pedic Tempur-Adapt Mattress, so I didn’t have high expectations for the Tempur-Adapt + Cooling Topper. However, I'm happy to report that it exceeded my expectations — I didn't wake up sweaty once." — Alison Barretta, Mattress Tester & Sleep Writer

Our Tempur-Adapt + Cooling Mattress Topper review score: ★★★★½

Stop reaching for your bags of frozen veg from the freezer — get this cooling pillow from Casper instead. This foam and fiber-fill pillow has a spongy feel and a medium loft that will suit most side and back sleepers. Its cooling prowess comes courtesy of Casper's HeatDelete Bands and CoolTouch cover, the same as you'd find in its premium cooling hybrids. The only way to save here is to purchase two pillows for a 20% discount, but you can either gift the other pillow to your sleeping partner or keep the spare for yourself. A 1-year warranty applies.

"The temperature-regulating feature is exactly as advertised, and kept me perfectly cool during the testing period. It's so adept at cooling, in fact, that I've had to break the Tom's Guide rating system." — Terri Williams, Product Tester

Our Casper Hybrid Snow Pillow review score: ★★★★½

1. Oura Ring 4: from $349 at Amazon
The Oura Ring remains the gold standard among sleep trackers. It has a sleek, non-invasive design and delivers a wealth of data with actionable sleep tips, a daily sleep score, and personalized advice from the Oura Advisor AI chat. Unfortunately, it's rarely on sale, and a subscription is required to use it (the first month is free for new users; it costs $5.99/month thereafter). However, if you're serious about tracking your sleep, this is the smart ring to get.

"I found [the Oura Ring 4's] scores to be very accurate. Testing the ring through summer meant I had a few sweaty, restless nights. The ring always detected any disturbances in my sleep, and lowered my scores accordingly. I suspect its redesigned, flattened sensors helped maintain better skin contact and comfort, even in the heat." — Eve Davies, Sleep Tech Product Tester

Our Oura Ring 4 review score: ★★★★★

If you'd rather not wear a device to bed, try this low-maintenance sleep tracker from Withings, which you can place under your mattress. It doesn't require a subscription to use, and although it's not on sale, it's still more affordable than most wearables that have similar features. Notably, it can be used to detect sleep apnea — and a recent partnership with Dune Health Sleep Clinic provides access to telemedicine for diagnosis and treatment. (It's covered by most insurance plans.)

"I was impressed by the metrics Withings gave me and felt they accurately calculated my sleep timings and nighttime interruptions with wake periods lining up with my own calculations. I also felt more tired on days when my sleep score was lower the night before." — Eve Davies, Sleep Tech Product Tester

Our Withings Sleep Analyzer review score: ★★★★

Maybe you don't need a watch or ring to wear 24/7 — if that's the case, this armband from Garmin is made exclusively to monitor your sleep. The tracker sits in a stretchy nylon armband that's generally undetectable. Not only does it collect sleep data, it also has a built-in vibrating alarm to gently pull you from your slumber. AI-powered insights and an enhanced performance dashboard are available with an optional Garmin Connect+ subscription.

"Personally, I love the Garmin Index Sleep Monitor and find it works well for me as a dedicated Garmin user (I track my runs, workouts and day-to-day activity with the Garmin Forerunner 255) who dislikes wearing a watch to bed but still wants a holistic view of my fitness, sleep and recovery." — Eve Davies, Sleep Tech Product Tester
