The Truth About Cooling Weighted Blankets—What You Need to Know

Think weighted blankets are just for winter? You’re not the only one—and we totally get it.

If the idea of curling up under a heavy blanket sounds more like a sweaty nightmare than a soothing escape, you’re probably picturing yourself tangled in a heat trap, tossing and turning. Sleeping hot is a real struggle, and it’s one of the biggest hesitations we hear from shoppers.

But here’s what most people don’t realise: it’s not the weight that’s making you overheat—it’s the materials! So if you’ve written off the calming, stress-relieving power of weighted blankets because summer is on the horizon—or because you’re someone who sleeps warm year-round—it’s time to reconsider.

Let’s break down what makes a weighted blanket cooling, what to avoid, and how to find one that delivers the best cosy comfort without any of the dreaded night sweats.

Why Traditional Weighted Blankets Always Feel Too Hot

Not all weighted blankets are created equal, and here’s the uncomfortable truth: most are built for mass production, not for your overall comfort. 

Many big-box brands cut corners by using heat-trapping materials like polyester shells, dense cotton fill, and plastic pellets. Why? Because they’re cheap, easy to manufacture, and they look like they do the job. But once you’re resting under one, this is simply not the case.

These materials don’t breathe. They cling. They trap heat and moisture. They leave you sleepless and sweaty. Sadly, more often than not, this means your cosy self-care moment turns into a middle-of-the-night escape act—kicking off covers, flipping your pillow, and staring at the ceiling for hours on end.

Here’s where most sleepers get it wrong: they assume all weighted blankets are like this. But the problem isn’t the weight. It’s the tech (or lack thereof) behind the blanket’s design and the cheap materials being chosen. The real issue? Your body can’t regulate its temperature under synthetic fabrics and non-breathable fillers. Instead of calming your nervous system (which is the point of a weighted blanket), your body goes into overdrive trying to cool down.

And if you're shopping based on price alone, that cheap blanket could cost you your sleep—literally!

What You Actually Want (& Need!) In A Weighted Blanket

Weighted blankets should be created with one goal in mind: to deliver calming, cooling, sleep-enhancing comfort, no matter the season. Here’s what makes the Cosy House Bamboo Weighted Blanket different from the old-school, heat-trapping options:

1. A Cover That Breathes Better Than Cotton

Cosy’s included removable cover is made from 100% viscose derived from bamboo, known for its natural moisture-wicking, breathable, and buttery-soft properties. Unlike cotton or synthetic fabrics, bamboo lets air circulate freely and naturally draws moisture away from your body. So instead of waking up damp and restless, you wake up dry, cool, and more refreshed!

2. Evenly Distributed Glass Beads 

Inside, thousands of tiny, premium-grade glass beads are sewn into a precise quilted pattern that keeps the weight evenly spread. That means no bunching, no shifting, and no spots where heat builds up. This enhanced design provides gentle deep-touch pressure stimulation that supports your ultimate relaxation and deeper sleep, all year round. [1]

3. Smart Temperature Regulation

The combination of breathable bamboo fabric and the even weight distribution helps your body naturally regulate its temperature. It’s just enough pressure to calm your nervous system, without adding any excess warmth or ruining your zen. And yes, it’s still perfect for colder nights. Just layer it under your duvet in the winter, and you’ve got a warm, anxiety-reducing cocoon.

Benefits That NEVER Go Out Of Season

Some products are seasonal. Weighted blankets shouldn’t be. Whether it’s midsummer or midwinter, here’s what doesn’t change when you buy the Cosy Bamboo Weighted Blanket:

• Weighted blankets have been shown to reduce stress and anxiety. Deep pressure stimulation is like a full-body hug that signals your nervous system to calm down. This gentle, even pressure activates relaxation points across your body, helping reduce cortisol (the stress hormone) while boosting serotonin and melatonin levels. This then slows heart rate, calms the mind, and promotes deeper, more restorative sleep—night after night, season after season. [1]

• Studies show that weighted blankets can help you fall asleep faster and stay asleep longer. Weighted blankets are frequently recommended by sleep experts and occupational therapists for people with anxiety, insomnia, or restlessness. [1,2,3]

• Our weighted blanket is easy to clean and care for! The zippered 100% Viscose from Bamboo Blanket Cover is machine washable, hypoallergenic, and resistant to stains, wrinkles, and bobbles—so you can sleep cleaner, longer. Simply remove the cover and place it in the washer (machine wash in cold water, tumble dry on low).

• Our weighted blanket is always silky-smooth and soft. We only use the highest quality materials to create our Bamboo Weighted Blanket, so you can cuddle up anywhere in your home—from the bedroom to the sofa and beyond.

• Our weighted blanket is extra durable for year-round use. This weighted blanket features a reinforced multi-layer design with rip-resistant pockets, leak-proof stitching, and 8 secure loops to keep everything in place, all under the breathable bamboo cover!

How to Use a Weighted Blanket All Year Long

When made with the right materials, a premium weighted blanket can become your go-to comfort companion in every season. Here's how to use the Cosy Bamboo Weighted Blanket year-round for better sleep, less stress, and more cosy moments, no matter the weather:

• In The Summer: Ditch the duvet and pair your weighted blanket with just a sheet. Our bamboo viscose cover wicks moisture, enhances airflow, and feels cool to the touch, even on those sticky, muggy nights. Many hot sleepers report feeling cooler thanks to the way deep pressure stimulation soothes and helps reduce midnight tossing and turning. [1,2,3]

• In The Winter: Layer it under or over your duvet or blankets for a cocooning effect that doesn’t just warm—it relaxes. The weight delivers full-body pressure that signals your brain it’s safe to unwind, helping you fall asleep faster and stay asleep longer without overheating.

• For Daily Downtime: Not just for bed—drape it over your lap during your morning coffee, throw it across your shoulders for post-work decompression, or use it to unwind during TV time. Keep one in your home office for calming midday breaks, or offer it to guests who need help winding down after travel!
