When renowned Japanese pain specialist Dr. Hiroshi Tanaka made a shocking discovery at the Tokyo Spine Institute, even his colleagues couldn’t believe it.
“What we discovered in our sleep lab was disturbing,” reveals Dr. Tanaka. 83% of people are hurting their bodies literally every night – and they don’t even know it.”
Here’s the horrifying truth: That ordinary pillow on your bed is silently destroying your health.
Using advanced muscle monitoring technology, Dr. Tanaka’s research revealed something alarming: Your trapezius muscle—the vital connector between your neck and shoulders—never gets a chance to rest. This muscle is locked in constant tension throughout the night.
“It’s like torturing the body,” explains Dr. Tanaka. Think about it; You are not ready to stand with a crooked neck for 8 hours a day. But that’s exactly what your regular pillow does to you every night.”
This explains why:
- Your neck pain keeps getting worse
- Those headaches will not stop you
- Every night you feel that your sleep is less refreshing
- Expensive treatments only work temporarily
And according to Dr. Tanaka’s research, this is just the beginning of the damage…
The shocking “pain cascade effect” your pillow activates every night
Dr. Tanaka’s research revealed something even more troubling—what he calls “The Pain Cascade Effect.”
“What starts with your neck is just the beginning,” warns Dr. Tanaka. “We discovered that this nighttime muscle tension sets off a devastating chain reaction throughout your upper body.”
Here’s what happens when you sleep:
First, your neck muscles lock up—like an overstretched rubber band. Then, this tension spreads to your shoulders, just like dominoes falling in a row.
Eventually, this tension creeps into your upper back, creating a web of pain that’s nearly impossible to untangle.
But the situation gets worse.
Using specialized blood flow imaging, Dr. Tanaka’s team discovered something frightening. This constant muscle tension actually blocks the vital blood supply to these areas. “It’s like your body is slowly suffocating these muscles every night,” he explains.
The result? A vicious cycle that gets worse over time:
- Your chronic pain deepens
- Your muscles are getting more tired every day
- Daily discomfort becomes your new “normal.”
- Your upper body ages faster than it should
“The most troubling part is that traditional treatments can’t stop this cascade,” adds Dr. Tanaka. “As long as you’re using a regular pillow, you’re resetting this damaging cycle every night.”
The worst part? Sleeping this way also greatly increases the chances of getting a migraine.
Not just regular headaches—we’re talking about those migraines that knock you off your feet, are accompanied by dizziness, blurred vision, and sometimes even nausea.

Urgent warning: your pillow may be the cause of dangerous nerve problems
“What we discovered about migraines was the scariest part of our research,” says Dr. Tanaka in a more serious tone. “The wrong pillow doesn’t just cause pain – it can trigger severe neurological events.”
During his 25-year study at the Tokyo Spine Institute, Dr. Tanaka noticed a recurring pattern. Those seemingly innocent pillows weren’t just causing discomfort, they were creating what he calls a “neurological nightmare”:
🚨 You may be at risk if you experience:
- Headaches that seem to come out of nowhere
- Sudden attacks of dizziness
- Seeing those strange spots in your field of vision
- Nausea for no apparent reason
- You’re staring at lights that never bothered you before
“But this is what really gets my blood boiling,” says Dr. Tanaka. The medical industry is making a fortune off your suffering.”

The shocking truth about visits to a chiropractor (spine adjustment specialist):
- 7 or 8 out of 10 patients become regular customers
- Each visit costs you 60 to 120 euros
- This amount reaches 3,000 to 6,000 euros per year
- And not to mention the dangers: possible strokes, spinal cord injuries, bone damage
Dr. Tanaka explains, “I’ve seen many patients empty their wallets for temporary solutions. “Meanwhile, their pillow—the culprit—continues to destroy their health every night.”
Devastating financial impact:
- Age 30-40: 3,000 euros per year
- Age 40-50: 4,500 euros per year
- Age 50+: €6,000+ per year
Lifetime cost: That’s over €150,000 spent on treatments that never solve the real problem!
And here’s the bottom line: As you get older, these problems snowball. Your muscles tire faster, you need more time to recover, and those treatments? They just get more and more expensive. Meanwhile, chiropractors laugh and count your pennies.
The solution: a combination of modern science and traditional Japanese medicine
After seeing thousands of patients suffer, Dr. Tanaka knew there had to be a better way. He combined the ancient principles of Japanese reflexology with the modern science of sleep, and what he discovered changed everything.
Dr. Tanaka explains, “In traditional Japanese medicine, we know that the meridian points (energy pathways) of the body must be properly aligned during sleep. But western pillows? They completely ignore this vital factor.”
Working with an elite team of sleep specialists and ergonomics experts, Dr. Tanaka helped develop something revolutionary. “When patients see it for the first time, they’re skeptical,” he admits. But only after one night, they realize. “It’s not just a pillow – it’s a medical breakthrough.”

Working with an elite team of sleep specialists and ergonomics experts, Dr. Tanaka helped develop the revolutionary Derila Ergo pillow.
The science behind this remarkable development:
Dr. Tanaka’s research revealed three critical factors for proper muscle relaxation:
- Your neck should have just the right curve.
- Certain pressure points must be activated.
- Your spine should remain perfectly aligned.
The result? A pillow that looks different, because it really is.
“In our sleep studies, we saw something remarkable,” notes Dr. Tanaka. “The trapezius muscle actually began to release its chronic tension patterns after just a few nights.”
Warning: Yes, this pillow may seem unusual at first glance. But don’t let its appearance fool you. This is the result of decades of research and thousands of clinical observations. And once you experience the difference, you’ll never hurt your body again using regular pillows.
“Revolutionary tension release technology” that is changing lives
What makes this pillow different is our discovery of pressure distribution. Traditional pillows create what we call “Tension Hotspots”—areas where dangerous pressure builds up throughout the night.
Groundbreaking science behind full support:
Through thousands of clinical observations at the Tokyo Spine Institute, Dr. Tanaka’s team determined exactly what your body needs for optimal recovery:
- Those who sleep on their backs (archers)? Your neck needs that perfect natural curve – just like when you’re standing straight. Without it, your muscles will be working overtime all night.
- Side sleepers? Those pressure points in your shoulders and neck need precise support. Otherwise, your spine will twist like a pretzel.
- Those who sleep on their stomachs? You need strategic support to avoid that dangerous neck twist that destroys your muscles.
“But this is where our breakthrough changes everything,” explains Dr. Tanaka excitedly.
Their research resulted in a support system that:
- It distributes the weight of your head evenly, like a gentle supporting hand.
- It keeps your spine as straight as an arrow all night long.
- It precisely targets those healing pressure points.
- And finally, it allows those involved muscles to relax and recover.
What is really happening to your neck?
Studies Thermal imaging Dr. Tanaka revealed something that shocked even himself. He shows me a series of heat maps, pointing out bright red areas around the neck and shoulders.
“Most people’s trapezius muscles are literally screaming for help all night long,” he explains, tracing angry red patterns. “They’re locked in a constant state of stress that regular pillows make worse with every passing hour.”
Think of it this way: Right now, your neck muscles are probably tight. You may even be rubbing them unconsciously. Now imagine this tension multiplied by eight hours of weak support during sleep.
Dr. Tanaka’s research shows that a proper support system should:
- Release that trapped muscle tension (like a gentle all-night massage).
- Target those natural healing points (the same points that acupuncturists target).
- Prevent dangerous pressure build-up (no more morning dryness).
- Keeps your spine perfectly aligned (like an invisible posture coach).
Leaning in for emphasis, Dr. Tanaka adds, “After treating thousands of patients, I can tell you this with confidence: Your body is desperately trying to heal itself every night. But to do this, it needs proper support.”

Exclusive: Dr. Tanaka reviews my 9-week therapeutic journey with Derila Ergo
When I shared my sleep diary with Dr. Tanaka, he noticed something amazing about how the body heals when given the right support. He walked me through each stage of recovery and explained what was happening beneath the surface.
First week: start of treatment
“This is exactly what we observed in our clinical trials,” explains Dr. Tanaka, referring to my initial notes. “The body begins its healing process cautiously, like testing new waters.”
My experience:
- Night 1-2: Minor adjustments as my body adapts.
- Night 3: First significant reduction in neck tension.
- Night 4-7: Waking up feeling amazingly refreshed.
“Your trapezius muscle was finally releasing years of built-up tension,” explains Dr. Tanaka. Like a slowly opening fist.
Week 5: Scientifically proven deep healing
“That’s when the real transformation begins,” notes Dr. Tanaka, reviewing the data from my smartwatch. Numbers don’t lie:
Documented results:
- Deep sleep increased by 47%
- REM sleep cycles were normalized
- Muscle tension decreased by 68%
- The pain level decreased dramatically
Warning from Dr. Tanaka: “The damage from years of using regular pillows can be severe. “The sooner you change your pillow, the better your chances of a full recovery.”
9th week: complete transformation of sleep
When I told Dr. Tanaka that I no longer needed melatonin to sleep, he was not surprised. “When the body achieves proper alignment, it naturally regulates sleep hormones,” she explains.
The changes were significant:
- My sleep quality improved beyond what I thought it would be
- My body started producing melatonin naturally again
- Morning pain? Completely gone
- I was finally getting a quality of sleep that I haven’t had since I was 20 years old
“These results are exactly the same as what we’ve seen in thousands of patients,” confirms Dr. Tanaka. But then her face scrunches up: “That’s what worries me: Every night you spend on a normal pillow adds to the damage.”
