🏆 2025 Health Sleep Award Winner — Evercool® Starter Sheet Set Independently verified by SGS SA, the global leader in product testing. Also a 3-time Good Housekeeping Bedding Award winner.

Introduction

Nearly 80% of women in perimenopause and menopause experience hot flashes, and they are one of the leading drivers of chronic insomnia in midlife women. The cycle is brutal: you fall asleep, your core temperature spikes, you wake up drenched, and the rest of the night dissolves into restless tossing and damp sheets.

Experts increasingly point to bedding as a meaningful first step; cooling sheets engineered to actively regulate body temperature can deliver measurable relief before any pharmaceutical intervention. The right surface against your skin matters more than most women realize.

That’s where the Rest® Evercool® Starter Sheet Set enters the conversation. Winner of the 2025 Health Sleep Award, it has emerged as one of the best sleep devices for insomnia caused by menopause-related temperature dysregulation, and we spent weeks digging into why.

What Is the Rest® Evercool® Starter Sheet Set?

At its core, the Evercool® Starter Sheet Set is built around Rest’s proprietary Evercool® fabric; a precision-engineered fiber 75× thinner than human hair that draws heat away from the body on contact. Unlike most “cooling” sheets that rely on chemical coatings, Evercool®’s temperature-regulating properties are permanently woven into the fabric itself.

Independent thermal imaging tests show Evercool® outperforming traditional cotton, silk, and bamboo at conducting heat away from the skin which translates directly into fewer overnight wake-ups for hot sleepers and women in menopause.

5 Reasons the Evercool® Stands Apart

•         Instant Cool-to-Touch - One of the highest Qmax ratings on the market. Qmax measures how quickly a fabric draws heat from skin. Evercool® outperforms silk, bamboo, and cotton.

•         Advanced Moisture Wicking - Microscopic channels in the fabric pull sweat away and evaporate it rapidly; keeping you dry even during intense hot flashes.

•         IONIC+™ Antimicrobial Silver - Embedded silver ion yarns naturally prevent bacteria buildup and eliminate odors without chemical additives.

•         All-Night Airflow - Independent airflow testing confirms Evercool® is light and breathable. It actively releases trapped body heat while circulating cool air.

•         Chemical-Free & Permanent - No cooling coatings, no PFAS, no bisphenols. The cooling effect is engineered into the fabric structure itself and won’t wash out.

•         Third-Party Lab Certified - Tested and verified by SGS SA. Every performance claim is backed by published lab data.

Why Menopause Destroys Sleep And How Cooling Sheets Help

During menopause, declining estrogen levels disrupt the hypothalamus, the small region of the brain that regulates body temperature. The result is a hyper-sensitive thermal “thermostat” that triggers hot flashes and night sweats at the slightest provocation, often jolting women awake multiple times per night.

These overnight temperature surges fragment deep, restorative sleep stages. Over weeks and months, the cumulative sleep loss compounds into chronic insomnia, fatigue, mood disruption, and cognitive fog.

“Cooling sheets help manage menopausal night sweats and hot flashes by wicking away moisture and releasing trapped body heat, regulating your temperature to prevent damp, uncomfortable waking and improving overall sleep quality.”  Medical consensus from sleep physicians and menopause specialists

High-performance cooling fabrics work through two mechanisms simultaneously: they lower perceived skin temperature on contact by conducting heat away from the body, and they wick microscopic moisture droplets to the fabric surface where they evaporate before soaking through.

That is precisely why the best sleep devices for insomnia in this population start with the bedding surface itself long before more invasive interventions are considered.

Why Evercool® Works Where Other “Cooling” Sheets Fail

Most natural-fiber sheets marketed as “cooling”, bamboo, eucalyptus, and percale cotton, rely on passive breathability. They feel pleasant initially but can’t actively conduct heat. Evercool®’s engineered yarn structure physically pulls thermal energy from the skin and disperses it across the fabric surface, delivering measurable cooling that lasts the entire night.

What Women Are Saying About Sleep & Menopause Relief

★★★★★

“Always cool to the touch and helps with my hot flashes. I have the Rest Evercool Starter set because of menopausal night sweats. I can finally sleep through the night without waking up and having to stick my legs out of the sheets to cool off. It’s been life-changing.”

- Tonia K., Evercool Starter Set

★★★★★

May not completely prevent overheating, but heat dissipates faster

For context, I'm overweight, menopausal, and I have an autoimmune disease, all of which lend themselves to temperature dysregulation. I go to bed cold and wake up during the night hot and drenched in sweat. The Evercool fitted sheet and pillow case doesn't prevent the overheating (since my body is doing that), but when I roll over, away from the hot spot, I definitely notice that the material cools down quicker than our bamboo sheets did. If I kick off my overlayer that is holding in the heat, I get down to a more comfortable temperature quicker because the sheets are releasing the heat quicker. In short, although it's not a 100% fix for my situation, I seem to be sleeping better so that helps improve the quality of my sleep significantly."

- Nancy B., Verified Buyer

★★★★★

“These work great for hot flashes! Even my husband loves them! Highly recommend if you are a hot sleeper!”

- Paula W., Verified Buyer

★★★★★

“These sheets have been a lifesaver for me. When I started to buy them, I thought this is just another gimmick. But I am telling you that these sheets have saved me every night for the last six months. I have had the worst hot flashes at night since I started sleeping on these sheets I have not been awoken once with a hot flash. I love these sheets and the comforter thank you so much. I will be a repeat customer forever!”

- Elizabeth R., Evercool Sheets

★★★★★

“These sheets have honestly been life changing for me. I originally bought the starter pack and loved it so much that we ended up buying the top sheet too and I can confidently say they are worth every single penny.

I’ve been struggling with horrible night sweats from perimenopause, constantly waking up drenched, uncomfortable, and then freezing once the sweat soaked into the sheets. It was this miserable cycle of hot, cold, hot, cold all night long that completely wrecked my sleep.

These sheets changed that almost immediately.

What’s so hard to explain is that even when you do sweat, the moisture doesn’t seem to sit in the sheets the same way regular bedding does. You don’t get that awful clammy, soaked feeling where suddenly you’re freezing because everything underneath you is damp. The temperature stays comfortable and balanced somehow, and I’m sleeping through the night so much better because of it.

The fabric feels cool, soft, breathable, and luxurious without feeling slippery or stiff. You can tell they’re high quality the second you crawl into bed. It genuinely feels like sleeping in a hotel bed every night now.

I was hesitant because of the price, but after dealing with perimenopause symptoms and terrible sleep for so long, I would buy them again a hundred times over. Good sleep is priceless, and these sheets have made a bigger difference than I ever expected.

If you deal with night sweats, overheating, or just want the most comfortable sheets ever!  Get them. They’ve been one of the best purchases we’ve made for our home.”
