As outside temperatures grow chilly, weighted blankets can be a popular choice to warm up. Some people say the added pressure helps them soothe the worries of the day and get to sleep faster.

But research on the effectiveness of weighted blankets is limited. Here’s what to know.

Weighted blankets come with extra heft in the form of glass beads, pellets, cotton or another filling. Scientists haven’t studied exactly how the blankets work, but they have a few ideas. The blankets’ firm touch may calm the brain’s fight-or-flight response, said Dr. Neal Walia, a sleep medicine expert at UCLA Health.

“The evenly distributed weight on you tells your body, ‘Hey, you’re in a calm environment,’” he said.

The extra pressure also may signal the brain to release what’s called the love hormone, also known as oxytocin. It’s produced during bonding and cuddling, and can also lower anxiety, Walia said.

How do I use a weighted blanket? For most healthy adults, experts say to choose a blanket that is about 10% of their body weight. So, a 150-pound person may opt for a 15-pound blanket.

Weighted blankets are not recommended for babies or toddlers since they can hinder movement and breathing. People with sleep apnea, sleep-related disorders or respiratory problems should check with a doctor before using a weighted blanket.

The blankets aren’t for everyone, and each person gets the best out of their blanket differently. For example, some may find them too hot to use during warmer months.

And the extra swaddling comes at a cost: quality weighted blankets can range from $50 to over $300 depending on the size, weight and material.

Can weighted blankets improve sleep? There are some hints that weighted blankets can help with anxiety, chronic pain and sleep. But the research isn’t conclusive.

Even though there’s not yet strong evidence to back up the benefits of weighted blankets, sleep experts say there’s no harm in giving them a try if you’re willing to splurge.

Dr. Neal Walia (interview): “There’s not a large amount of studies on weighted blankets. There’s a few out there, few on pediatric populations, particularly children with autism, a few on adult population. So those are pretty small studies and a few on adult populations that have, let’s say, anxiety disorders or ADHD, bipolar, things like that. And those populations have been studied. All of these are relatively small studies with a common thread that it’s not a very harmful intervention. And for the most part it was either beneficial or neutral.”

Dr. Neal Walia (interview): “There’s two thought processes on these. One is that when you can’t fall asleep or stay asleep, it can be driven by your sympathetic system, basically like a heightened sense of arousal. So patients a lot of times they’ll say, you know, I’m tired, tired, tired. I lay in bed, I’m like wide awake and thinking about my day, my thoughts don’t stop going. And their sympathetic system or fight or flight is essentially heightened. And the idea is that whenever you’re using what’s called deep pressure touch or pressure stimulation, the parasympathetic system, which is your rest and digest system, is activated. So the idea of evenly distributed weight on you kind of tells your body, hey, you’re in a calm environment.”

Dr. Neal Walia (interview): “The other idea is that it, in a similar sense of a hug, kind of tells your body to start producing oxytocin, which is a chemical that’s also this endogenous anti-anxiety chemical – is what we think – that can help also stimulate the parasympathetic system. So the idea is just like that pressure provides your body this comfort that you can, in two ways, promote sleep and rest. Both of those are theoretical. It’s not like we’re being able to study like chemical levels and things like that. But with the low side effect profile and risk profile – not a bad idea.”

Dr. Neal Walia (interview): “If there’s any indication that there might be an underlying sleep apnea or other sleep pathology, you should get that evaluated. But particularly if there’s an insomnia component, then absolutely maintain sleep hygiene as well. Introduce a weighted blanket, if it works that’s great. And if it doesn’t work, that’s okay.”

Dr. Neal Walia (interview): “As long as they’re evenly distributed weight and it’s not too heavy, that’s the big part of it. Anecdotally, I’ve had patients that have used all types and they either – whether they had benefit or didn’t have benefit, didn’t seem to correlate to the type of material that was used.”
