Using A Xalm™ Blanket Has Incredible Health Benefits:
Boost Mental Clarity & Memory
Research is clear, the quality of your sleep directly effects your cognitive abilities. When you get enough sleep you can think clearer and memory is improved.
Increase Mood & Wellbeing
Studies show poor sleep quality are very closely correlated to depression and anxiety. 
Optimise Physical Health
Poor sleep can have a huge negative impact on physical health. People who don’t get enough sleep are more at risk of decreased immunity, heart attacks, heart disease, strokes and alzheimers.
Better Chance Of Weight Loss
Stress and not getting enough sleep are major contributors to obesity. Evidence shows feeling stressed and not getting enough sleep make it around 50% less likely you will be able to lose weight.
Here’s what the media says about weighted blankets:
"I wake up in the same position that I fell asleep in, and I also don't have anxiety attacks waking me up,"
“Yes, you really do need a weighted blanket”
“Yes, you really do need a weighted blanket”
“The weight of the soft, 15-pound blanket made me feel like a small baby being cradled in my mother’s arms.”
‘It can help you let go of the day, become still and stop restlessness — all of which are conducive to deep and restorative sleep.’ Dr Nerina Ramlakhan, sleep expert.

“My breathing slowed and I was yawning almost instantly. Lying under the blanket is deeply comforting.”

Xalm blankets are ahead of the curve when it comes to insomnia care and treatment. While recent evidence based research is slowly catching up, Xalm have drawn on the expertise of thousands of professionals on the ground.

Unlike medication prescribed by a doctor, Xalm blankets have no side effects and are utilised by you, the user. This gives you the ability to take back control of your mood and sleep, adjusting the blanket to suit your personal needs.

I personally recommend that patients should always try safe, natural treatments like the Xalm blankets first, before they try more invasive treatments which may have unintended consequences.
Here's what customers think about their Xalm™ blanket:

Rowan M - Reading, Berkshire - ★★★★★


I bought this super heavy blanket for my wife who often struggles to get to sleep. it works a treat for her.. she is asleep within minutes!

Osty Clément - Islington, London - ★★★★★

I struggled a lot with insomnia and had a lot of trouble falling asleep and then someone told me about these. 

Since it arrived I noticed a huge difference. I went from to falling asleep in two hours to doing so in 15-20 minutes. 

Sandra D - London - ★★★★★


I was sceptical about its claims to help you sleep better, but having struggled with sleep problems for years I can wholeheartedly say it does!

So what's the science behind weighted blankets?
The key to a good night’s sleep is a little-known hormone already locked-up inside your body.
Before you say it — we're not talking about melatonin. 

Or serotonin. 

Or any of the other hormones you know of.

In fact, chances are you’ve never even heard of this one.

And if you have — you’ve probably never heard that it could be your VIP ticket to a blissful night of sleep, whenever you want it.

It’s called oxytocin.

Some call it the “cuddle hormone” because your body releases it if you embrace someone you love.

But many experts simply call it…
“Nature’s bliss molecule”
Believe us: It lives up to its name.

A landmark study published in the journal of Regulatory Peptides showed that oxytocin naturally promotes sleep by BLOCKING the effects of cortisol. 

And the more oxytocin you have floating around your body at night, the more your chances of falling into a natural, peaceful sleep go UP — because it beats cortisol to the punch at every opportunity. 

When cortisol is telling everything to wake up … oxytocin is telling everything to relax!

…The kind of relaxation that instantly shuts-off any racing thoughts… 

...That silences that inner voice in your head that normally won’t stop talking. 

...That gives you the freedom to simply drop off to sleep like everyone else does.

In other words, the kind of relaxation you NEED to be able to fall asleep within minutes of your head hitting the pillow!

There’s just one drawback. 

You see, when it comes to the long list of hormones naturally released by your body, nature’s bliss molecule is hands-down the most well-guarded.

All the others are released no matter what you do:

Cortisol is released whenever you feel stress…

Insulin is released whenever you eat carbohydrates…

Dopamine is released whenever you feel happy…

Yet, oxytocin is locked away inside a pea-sized gland deep inside your brain.
Normally — it’s only released under a set of 
very specific circumstances
It can’t be triggered by your diet… 

...by supplements…

...or by prescription pills. 

And even if you do manage to flip this hormone’s switch to the “on” position — for example, by cuddling someone you love — it acts like a pressure gauge … taking over 20 seconds before the first molecules trickle into your bloodstream. 

If you stop what you’re doing just ONE second too soon…

...That switch flips back to the “off” position and all the sleep-inducing benefits that were just moments away are GONE. 

Sounds like a lot of effort, I know…
But new research shows you can unlock
this sleep-inducing hormone every night, like clockwork — with absolutely no effort at all!
In 1992, a researcher and professor called Dr Temple Grandin discovered a unique feature of our skin…

Every skin cell on our bodies has a Goldilocks-like “pressure-switch” inside it…

Press down on your arm just a little … and you know something is touching you. 

Press on it too much … and you feel pain.

But when you push those pressure-switches with just the right amount of “deep touch” … it feels nice … relaxing ... soothing.

Like when you hold a loved one’s hand…

When someone strokes their fingers through your hair…

Or when you get a massage at a spa.

Those things don’t just feel good on the outside — behind-the-scenes, that deep touch sets off a chain reaction of all the feel-good hormones that switch off your stress response...

…allowing you to truly relax and unwind!

Occupational therapists were understandably excited about a treatment that didn’t require any medication. And had ZERO side effects!  

But they struggled for several years to find a reliable way to use this new discovery. After all, they couldn’t simply tell their patients to visit a spa every day for a professional massage!

Then, in 1997...
A way to truly tap into the calming
effects of “deep touch” was born...
They called it a “weighted blanket”.

Within 12 months, therapists across the world were snatching them up by the case-load and shipping them off to their patients to try.

They sent them to parents of Autistic children … to parents of children with ADHD … to adults with Fibromyalgia … adults with restless leg syndrome … and adults with insomnia. 

The results were OVERWHELMINGLY positive!

It’s no wonder.

Because, by wrapping a weighted blanket around your body, your skin feels that same deep touch that Dr Grandin discovered over two decades ago. 

And sure enough, after passing that 20 second barrier — your body is tricked into releasing the sleep-inducing bliss molecule ... just as though you were being hugged closely by a loved one.

This isn’t some trumped-up scientific theory that’s only been tested inside a lab...

It's FACT.

...backed by all the real-world evidence you’ll ever need. 
Over 52,562 people are already sleeping better
than they have in years because of Dr Grandins discovery.

RRP £29.95 - Today FREE
If you’ve struggled with sleep problems more than once before … or you’re struggling right now … and … if you’re finding it harder to get to sleep as you get older…

...then a Harvard Medical School study says the problem may vanish completely when you boost your levels of melatonin! 

By supplementing with melatonin, you can virtually “reset” your internal sleep clock almost overnight! Making it even easier to get to sleep tonight, and every night after!

But you don't want to just supplement with any melatonin product on the market. I very strongly believe you should choose natural products where possible.

That's why i love Xalm's CherryBliss sleep supplement.

It contains Montmorency Cherry, the most abundant source of natural melatonin known to man.

Now, you might have already heard of Montmorency Cherry...

Just like weighted blankets — the popularity of this sleep-aid has shot through the roof in recent years.

...With good reason!

Because Montmorency Cherry has been proven to significantly increase the levels of your master sleep hormone, melatonin.

Northumbria University in the U.K. carried out a randomized, double-blind, placebo-controlled study — testing the effect of Montmorency Cherry on melatonin levels and sleep quality. 

Their results were conclusive. 

Total melatonin content was SIGNIFICANTLY elevated in the cherry group and there were significant increases of:

Time in bed...
Total sleep time...
And sleep efficiency... 

So not only will you get to sleep faster with your Xalm Blissful Sleep Weighted Blanket...

By combining it with Montmorency Cherry — your chances of a full night’s sleep go through the roof!

And if you’re wondering why Xalm chose Montmorency Cherry instead of other popular sleep-aids like valerian … or standard melatonin supplements … or herbal tea … then maybe the following groundbreaking research will make it clear. 

A study published in the Journal of Medicinal Food showed that Montmorency Cherry had beneficial effects on sleep that EXCEEDED — or at least equalled — valerian and melatonin!

Not only that…

...but Montmorency Cherry is one of the only completely natural sources of melatonin in existence! 

So you know for a FACT you’re not swallowing something that some nameless company cooked up in a lab.

Bottom line: 

CherryBliss is the perfect sidekick to your Blissful Sleep Weighted Blanket!

Your blanket should generally be between 8 - 12% of your body weight. We have a guide that you can check out here:


Or if you prefer a written guide:

If you weigh between 36 - 56kg you should get the 4.5kg blanket.

If you weigh between 56 - 79kg you should get the 6.8kg blanket.

If you weigh 79kg+ you should get the 9kg blanket.
Is this right for me?
If you're someone who likes the feeling of being tucked in or swaddled then this product is definitely for you. If you do not like the feeling of heavy blankets on you we would not recommend you buy it.

Other than that weighted blankets are a great natural option for insomnia sufferers, people who want to de-stress or as a possible tool to help relieve anxiety.
How does the trial work?
We offer a 7 night trial period to let you sleep with our products before you commit to buying. Your Xalm will ship within 1 business day via a 2 day service. Once we ship your order, a temporary hold will be applied to the card you use at checkout for the full amount of the blanket less the £1 already paid, which may appear as “pending” or “processing” on your account.

Will this help me sleep?
Yes many of our users report our blankets help them fall asleep faster and stay asleep through the night better.
How big are your blankets?
Our blankets come in a large 80" x 60" size. Ideally they are used for one person but it is possible to fit two under one blanket fairly comfortably. See our sizing chart for a better idea.
Will this make me too hot?
Every blanket comes with a removable minky cover. Take the cover off if you prefer a cooler cotton only blanket. 

That being said, the blankets aren't as hot as you would think. As they are mainly glass micro-beads and very little material they are actually quite breathable allowing you to get an incredible nights sleep.
Will this help my anxiety?
Legally (and morally) we can't guarantee it will help your anxiety but it has certainly helped lots of our previous users cope with anxiety and stress. If it doesn't help you can always return it for a full refund.

If you think you are suffering from anxiety we highly recommend you see your doctor as soon as possible to get proper medical help.
Do these really work?
Yes they are amazing! If they didn't work we wouldn't offer our incredible 100 night trial. If you don't agree with us (and thousands of happy customers) that our Xalm™ Blankets are amazing we'll refund you all of your money!
How do they work?
Using weighted deep touch technology that has been widely used for years as a treatment for anxiety in people with autism.

The weighted feeling of our Xalm™ Blankets help you drift into a deep natural sleep. People have described it like being gently hugged all over your body.

It's been clinically proven to reduce anxiety.

This secret technology has now just started to become more mainstream as people realise how much easier it is to get to sleep when you have deep touch stimulation from our weighted Xalm™ blankets.
How do i wash my blanket?
The outer blanket cover can be machine washed on a hand wash setting at a heat of 40°C or lower.

The inner weighted portion of the Xalm™ Blanket should be dry cleaned only!
Can i use this on my child?
If using with a child please be VERY careful and always supervise. Do not leave on small children whilst sleeping as this can lead to suffocation.
