You may have seen Instagram adverts pop up for weighted blankets recently, or heard friends talking about them, dubbing them "life-changing". How can a blanket be life changing? We decided to find out ... Weighted blankets, often known as gravity blankets because of a prominent brand, are covers designed to replicate the comforting feeling of a hug, thus reducing the user's anxiety and stress. Rather than a filling of microfibre or down, which are common in blankets and duvets, weighted blankets contain beads made of polyfill or glass and the weight is designed to be evenly distributed across your body. In short, the weight is designed to relax your nervous system, which relaxes your body and mind, in turn. "The blankets use the power of 'deep-touch pressure stimulation' to simulate the feeling of being held (like a hug). This increases serotonin and melatonin, the hormones responsible for relaxation, and decreases cortisol, the hormone responsible for stress," Gravity Blanket explains on its website. It is also said that they help people get to sleep quicker and go into a deeper night's sleep. "When using our Gravity Blankets across 1,000 nights of sleep, 72 per cent of participants in a 2019 study reported deeper, more restful sleep during the night. In addition, 76 per cent reported falling asleep faster. It’s science at work, for a better night’s sleep," the company says. Weighted blankets typically weigh between four to 12 kilograms. Stacey Siebritz, a Dubai resident and copywriter for a digital marketing agency, recently bought a weighted blanket, and sings its praises. "I bought it because I'm at the stage of lockdown life where I will try anything to improve my mental health and lower my anxiety," Siebritz tells<em> The National.</em> "It took a bit of getting used to – it felt heavier than I expected (mine weighs around 10kg) and making the bed with it is a workout in itself. "I was worried it would feel claustrophobic, but it’s actually very soothing to lie beneath it. The pressure of it is very calming," she says. "At the moment, I’m using it every night, although I’m slightly concerned that even with air conditioning, it might not be suitable for the peak of summer." Following a scan of the internet, Amazon.ae offers up the best selection of weighted blankets. Online, the blankets retail from around Dh125 to Dh350, depending on material, style, size and weight.
