Can Weighted Blankets Really Reduce Stress and Anxiety, or Are Those Claims a Bunch of Fluff?

When Atlanta-based editor Lauren Finney got her weighted blanket, it was initially on the recommendation of a physical therapist to help with her joint compression. Now, she tells Mental Floss, she can’t sleep without it. Chicago-based software developer Brandon Behr echoes that sentiment, telling Mental Floss that his weighted blanket “helps tremendously when the anxiety brain won't shut down long enough to fall asleep.”

Weighted blankets (also called gravity blankets), filled with pellets or another material to make them weigh about 10 pounds or more, are all over social media and ads, drawing buyers in with promises of complete comfort and a better night’s sleep. Most brands recommend getting one that’s 10 percent of your body weight for optimal relaxation and comfort.

“The concept is that the sensation may send messages to the brain that increases a sense of well-being,” Dr. Susan Lipkins, CEO of Real Psychology, tells Mental Floss. “Some research suggests that it is similar to pressure massages, which have been shown to help the brain calm down.”

Alternately, says Dr. Kristin Addison-Brown, owner of NEA Neuropsychology, it could have to do with a feeling of being swaddled—an evolutionary throwback to childhood when we felt more safe and secure from the feeling of being tightly wrapped. Ultimately, the purpose of weighted blankets is to bring down a person’s base-level anxiety so they can get some rest, Addison-Brown tells Mental Floss.

Light Evidence on Weighted Blankets

Weighted blankets have been touted by their manufacturers as a calming agent for people with anxiety and autism—but Lipkins and Addison-Brown both point out that no substantive peer-reviewed research has been done on them.

“Right now, the empirical evidence is pretty weak,” Addison-Brown says. “I did see one randomized controlled trial where [children with autism] used a weighted blanket versus a regular blanket, but that trial didn’t [show] any objective differences” [PDF].

Interestingly enough, Addison-Brown points out, even though the two groups saw the same results scientifically, the parents and children involved in the study all preferred to use the weighted blanket over a regular blanket. The findings appeared in the journal Archives of Disease in Childhood in 2013.

“There’s something inherently pleasing to us about [gravity blankets], but we don’t exactly know why and any real objective measures are not reflecting back,” she says.

Are weighted blankets worth it?

It’s not a one-blanket-fits-all solution. Some people may actively dislike them, and the blankets can cause problems for others. It takes some trial and error to see if they’re the right option.

“Gravity blankets seem to help some people some of the time,” Lipkins says. “The weight, for some, creates a secure and safe environment, allowing the person to relax and fall asleep more easily. Others may feel suffocated and like they can’t move.”

The most common complaints that weighted blanket users told Mental Floss match that idea. Canadian journalist Johanna Read didn’t like the way her blanket pushed her feet into a point. Illinois-based former car technician Noah Dionesotes says he couldn’t get comfortable because he likes to sleep with one leg out of the blanket. Wichita, Kansas, resident Jocelyn Russell says the blanket she bought is too heavy and, ironically, it gives her panic attacks.

In fact, weighted blankets have the potential to be dangerous: The deaths of two children, a 7-month-old and a 9-year-old, have been linked to them.

Neither Lipkins nor Addison-Brown are anxious to prescribe the blankets as a solution, especially since their safety hasn’t been fully established. Instead, they suggest first trying other, more natural ways to fall asleep: don’t watch television late at night, turn off your screens, set a regular bedtime and waking time, and avoid caffeine.

“[You could] also consult a psychologist to help find out what is keeping you awake and how to reduce stress and anxiety in healthful ways,” Lipkins adds.

All that being said, go ahead and try gravity blankets—as long as you do so safely.

“If you can afford it, I don’t see any real harm in it,” Addison-Brown says. “Though I would be very careful using it with people who may have any kind of muscle weakness. You also wouldn’t want to have a child or baby in the bed with you. Just use caution and common sense.”

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

How to Brew Your Own Fluorescent Beer at Home

If you're one of the many people who made their own sourdough starter in quarantine, you already know yeast is a living thing. That means its biological makeup can be tweaked using genetic engineering. As Gizmodo reports, that's exactly what a former NASA biologist has done to create his new fluorescent yeast kits.

A few years ago, Josiah Zayner left his job as a synthetic biologist for NASA to found The Odin, a company that lets anyone experiment with genetic science at home. His recently launched yeast kit accomplishes this in an eye-catching way. Thanks to a fluorescent protein from jellyfish, yeast that's been genetically modified with the kit glows green under a black or blue light.

Despite looking like a prop from a sci-fi film, the yeast is still yeast. That means it can be used in home-brewing projects if you want to take the science experiment a step further. According to Eater, yeast made with the kit ferments and fluoresces when added to honey and water. If you brew a batch of beer with the right amount of yeast, the final product will emit an otherworldly glow when viewed under a blacklight. The kit hasn't been FDA approved, but the company states the materials are nontoxic and nonallergenic, and beer made with it will still taste like beer.

You can purchase a fluorescent yeast kit from The Odin's online shop for $169. If you're looking for more ways to experiment with genetic technology at home, the company also sells kits that let you play with frog and bacteria DNA.
