Can You Use a Weighted Blanket in Summer?
One of the most common concerns about weighted blankets is that they will be too hot, especially during an Australian summer. And it is a fair question. When the temperature outside is pushing 35 degrees and you are already struggling to sleep in the heat, the last thing you want is something heavy on top of you making things worse.
The good news is that with the right approach, it is absolutely possible to enjoy the calming benefits of a weighted blanket without overheating. It comes down to understanding how they work, choosing the right materials and being smart about your sleep environment.
How Weighted Blankets Actually Work
Weighted blankets use a technique called deep pressure stimulation. The gentle, even pressure across your body mimics the feeling of being held or hugged, which can help calm the nervous system and encourage your body to produce serotonin and melatonin. This is why many people find them helpful for anxiety, restlessness and difficulty switching off at night.
The weight itself typically comes from glass beads or plastic pellets sewn into small pockets throughout the blanket. This distributed weight is what creates that grounding sensation. The important thing to understand is that the weight provides the benefit, not the insulation. So the fabric and fill material matter a lot when it comes to temperature.
Choosing the Right Weighted Blanket for Warm Weather
Not all weighted blankets are created equal, and this is where many people go wrong. If you buy a weighted blanket with a thick fleece or minky cover, of course it is going to feel like sleeping in a sauna. The key is to look for blankets made with breathable, temperature-regulating materials.
Materials That Keep You Cool
Cotton: Naturally breathable and moisture-wicking. A 100% cotton weighted blanket is one of the best options for Australian conditions. It allows air to circulate and helps draw sweat away from your body.
Bamboo: Even more breathable than cotton and naturally temperature-regulating. Bamboo fabric feels cool to the touch and is a great choice if you tend to sleep hot regardless of the season.
Glass beads: Compared to plastic pellets, glass beads retain less heat and are generally smaller, which means the blanket drapes more naturally and allows better airflow between the pockets.
Materials to Avoid in Summer
Fleece or minky covers: These are designed to trap warmth, which is the opposite of what you want during warmer months.
Polyester fills: Synthetic materials tend to trap heat and moisture, making you feel clammy and uncomfortable.
Tips for Using a Weighted Blanket in the Heat
Even with the right blanket, a few practical adjustments can make a big difference during summer.
Swap Your Duvet
You don't need a weighted blanket and a doona. If you are using a weighted blanket, ditch the duvet entirely and just use the weighted blanket on its own with a light cotton sheet underneath. This reduces the overall insulation without losing the calming pressure.
Cool Your Room First
Keeping your bedroom temperature between 18 and 22 degrees is ideal for sleep, weighted blanket or not. Use a fan, air conditioning, or open windows in the evening to bring the temperature down before bed. A cool room makes a much bigger difference than any single piece of bedding.
Only Cover the Parts That Need It
You don't have to cover your entire body. Some people find that draping the weighted blanket across their torso or legs only gives them enough pressure to feel calm without trapping too much heat. Experiment with what works for you.
"I was convinced I would have to put my weighted blanket away for summer but switching to just the cotton inner without the cover made all the difference. I use it year round now." - Mel R., Perth
Getting the Weight Right
The general recommendation is to choose a weighted blanket that is roughly 10% of your body weight. So if you weigh 70kg, a 7kg blanket is a good starting point. Going too heavy can feel restrictive and make overheating worse, while going too light won't give you the deep pressure benefits.
For children, the same 10% guideline applies, but it is always worth checking with a healthcare professional before introducing a weighted blanket, particularly for younger kids.
Who Should Avoid Weighted Blankets?
While weighted blankets are safe for most adults, they are not suitable for everyone. People with respiratory conditions, circulation issues or certain mobility limitations should speak to their doctor before using one. They are also not recommended for infants or very young children who might not be able to move the blanket off themselves.
Other Ways to Stay Cool and Sleep Well
If you find that a weighted blanket just isn't working for you in the heat, there are plenty of other ways to create a calm, comfortable sleep environment. Breathable bedding, a good mattress protector, keeping your room dark and blocking out noise with sleep-friendly audio solutions can all help you wind down and drift off more easily.
"The combination of a bamboo weighted blanket and a fan pointed at the bed is my summer sleep hack. I sleep so deeply now even on the hottest nights." - Tom J., Adelaide
The Bottom Line
A weighted blanket doesn't have to be a winter-only product. With the right material, the right weight and a few smart adjustments to your sleep setup, you can enjoy that calming, grounding sensation all year round. The key is choosing breathable fabrics, keeping your room cool and being willing to experiment with how you use it.
