FAQ
Q. Is the orthopedic pillow doctor's pillow different from the orthopedic pillow?
A. Orthopedic pillow Doctor's pillow and orthopedic pillow are different products.
The ``Orthopedic Pillow Doctor's Pillow'' sold at the Yamada Shuori Pillow Research Institute online shop is a pillow whose height can be adjusted by yourself from 40mm to 90mm.
You can check the instructions for adjusting it yourself and our automatic measurement system if necessary.
For orthopedic pillows, our staff will measure the height of your pillow through face-to-face measurements or ask you about your height, weight, etc. at the time of purchase, and will create the pillow to the height that suits your body.
Q. Why do I need the right pillow?
A. Not just any pillow is fine; you need to use the ``correct pillow'' that suits your body. On the other hand, using a pillow that doesn't fit your body can lead to physical problems such as stiff shoulders, headaches, and numb hands when you wake up in the morning.
You may also have trouble sleeping, such as waking up in the middle of the night with pain in your shoulder that is stuck under your body, taking off your pillow because it is uncomfortable, or sleeping on your stomach or with your hands on your back. It may also be caused by the wrong pillow.
Q. What is the correct pillow?
A. The right pillow is one that mainly meets the following three conditions.
1. Just the right size for you
When you lie down, you can rest your neck, but the height of the pillow is important.
Through experience and research, we have found that there is an optimal pillow height for each person.
You need to choose the right size pillow carefully and accurately. The suitable height will vary depending on the individual's physique.
If you sleep on your side or face up, measure the height of your pillow in a position that allows you to relax your neck bones and muscles and allow you to breathe deeply while sleeping.
If you sleep on your side, a straight line from your forehead to your nose, chin, and mid-chest should be parallel to the bedding surface.
If you sleep facing up, the appropriate height will be when you are leaning forward at about 15 degrees. An upward forward tilt of around 15 degrees widens the cervical intervertebral foramen (nerve exit) and at the same time secures the airway.
There are some people who have a difference of about 5 mm between the measurement results when facing sideways and when facing upward. The height condition is especially important among the three conditions, so please use a pillow that is just the right size and height that fits within that 5 mm range.
2. The material must have a flat shape and maintain its height.
Natural rolling over and stability of the neck (cervical vertebrae) are determined by the shape and material of the pillow. The best shape is one with no unevenness (flat) so that it does not interfere with turning over in bed.
Materials that cause your head to sink when you sleep, or shapes that raise your chin when you lie on your back, can put strain on your neck when you sleep.
Also, the key to the right pillow is that it is made of material that maintains the height of the correct size. By the way, the "orthopedic pillow" we sell uses urethane as the material.
3. Self-maintenance
Even if you get a pillow that is just the right size and has a flat structure, the body shape of the person using the pillow and the condition of the pillow are not constant.
It is necessary to review it as appropriate, depending on changes in the sleeper's physique and the shape of the pillow.
Regular maintenance is essential to keep up with such changes. In addition, the height of the pillow needs to be reviewed and readjusted throughout your life, depending on your weight gain or loss (the guideline is around 5kg) or changes in posture due to aging (such as a hunchback).
Please review the contents of the material accordingly and use a pillow of the optimal height.
Q. There are various types of pillows on sale, such as ``pillows that maintain an S-curve'' and ``pillows with uneven surfaces.'' Medically, what kind of effects do these pillows have?
A. There are many pillows and custom-made pillows on the market that maintain the S-curve of the neck.
However, according to research conducted at the pillow outpatient clinic of No. 16 Orthopedic Surgery Clinic, when examining X-ray images of the patient lying at the height of the pillow whose symptoms have improved, it can be seen that the bones of the neck have become straight. By straightening the neck bones, you can create more space between the bones. I think this may be similar to neck traction, which is one of the orthopedic treatments.
It is thought that the S-shaped curve of the neck acts as a cushion to support the weight of the head when standing or sitting, but when sleeping, the cushion function is unnecessary and the Being able to rest is important.
Therefore, the concept of maintaining an S-curve in the neck is incorrect. By the way, since your neck is straight when you are sleeping, is it okay to have a straight neck? I am sometimes asked.
In the first place, it is not medically clear whether there is a relationship between a straight neck and symptoms such as stiff shoulders. There are many people with straight necks who have no symptoms.
Orthopedic surgeon Shuori Yamada's conclusion is that the cervical vertebrae should be straight, at least while sleeping.
Q. Is it difficult to turn over if the pillow is uneven or the pillow has uneven contents?
A. There are many pillows on sale in the world, such as pillows with a vertical unevenness that conforms to the shape of your neck, and pillows with a horizontal unevenness that are said to be perfect for sleeping on your side or side. .
However, when thinking about pillows, it is of course important to consider the resting state, but at the same time, you should also think about the moving state (= turning over in bed).
Tossing and turning should be done unconsciously, and by the time you are conscious of turning over, you are already awake. Only when you can turn over easily will you be able to turn over unconsciously.
Turning over unconsciously can only be achieved with a flat structure. In terms of tossing and turning, unevenness only hinders the ability to roll over.
Also, it's not enough just to have a flat appearance; it's also important to have a firmness that remains flat when you rest your head on it. Furthermore, even if the pillow looks flat and has a certain degree of firmness, it is no different from a pillow with uneven contents that has unevenness.
Therefore, we believe that the only way to realize comfortable tossing and turning is with a flat sheet-like structure.
Q. Can symptoms such as neck pain, stiff shoulders, lower back pain, snoring, apnea syndrome, and insomnia be cured by using a pillow?
A. Good sleeping posture is very important for the spine (neck and lower back).
Symptoms may occur depending on the height of the pillow or the bedding environment (hardness of the rug, etc.), so we recommend that you first get into the correct sleeping position.
However, since the causes of the symptoms are various, it cannot be said that the pillow alone will improve the symptoms. If the condition does not improve even after adjusting the height and specifications of the pillow or the bedding environment, you may need to see a specialist.
Our products were developed with the aim of improving and alleviating various symptoms based on postural research by our representative director and physician, Shuori Yamada. There is no guarantee. Please understand this before considering your purchase.
Q. How do I care for my pillow?
A. Only the outer pillow cover can be washed. The inner inner cover and pillow itself cannot be washed. If you are concerned about the product's sweat or odor, please place it in a well-ventilated flat place away from direct sunlight.
Q.Is a pillow cover included?
A. Yes, it is included.
2.About specifications and functions
Q. What material is the pillow made of and how comfortable is it?
A. Sleeping comfort cannot be generalized as it varies depending on the bedding and individual differences, but since the pillow uses a relatively hard urethane or polyethylene sheet, it will feel quite hard.
The Orthopedic Pillow Doctor's Pillow is a hard, flat-shaped pillow that emphasizes tossing and turning, so some customers may find that the height of the pillow is not right in the beginning, or that the pillow continues to feel hard until they get used to it. welcome.
Each customer has their own height that suits their body, so if you sleep with a pillow at the appropriate height, you may not feel the pillow's firmness. Some customers also say that they have gotten used to it and it no longer feels hard.
Q. What kind of material is the pillow specifically made of?
A. There are 8 sheets in the package, but they are composed of a "low-resilience urethane sheet," "chip urethane sheet," and "polyethylene sheet." Although the pillow is hard overall, the area that touches the head is made with a low-resilience urethane sheet to soften the feel.
This image is part of the instruction manual and is a page that explains the material.
Q. Is it possible to adjust the height to suit me?
A. The instruction manual includes a ``pillow height guide'' based on your height and weight.
We also provide important points on how to check the height of your pillow.
Furthermore, if you use the "automatic measurement system", you can calculate the optimal pillow height. Please rest assured.
Q. How much can I change the height of the pillow?
A. It can be changed in 9 steps from 4.0cm to 9.0cm in 5mm intervals.
This image is part of the instruction manual and is a page that explains how to combine the sheets.
Q. It looks like there are stains and dust on the M sheet from the beginning.
A. Since the M sheet is a compressed material of different materials, spots of green, yellow, black, etc. can be seen from the beginning.
Please rest assured that there are no quality issues and there are no stains or mold. M sheet uses chip urethane, which is made by crushing urethane and bonding it together.
By performing such processing, urethane becomes extremely hard and solid. It is also a material often used in medical equipment for braces and has a reputation for its durability.
This image is an image of the M sheet.
Q.The T5 sheet feels sticky or moist.
A. The T5 sheet is made of low-resilience urethane material, so it may feel a little sticky or moist when you touch it. This is a characteristic of urethane material, so there is no problem with the quality. Please note.
Q. There is a peculiar smell coming from my pillow. What is it?
A. Due to the raw materials used, there may be a distinctive odor of the material (urethane) left immediately after delivery, but the odor will disappear if you dry it in the shade for 2-3 days in a well-ventilated place.
Q. Is this product by No. 16 Orthopedic Surgery Dr. Shuori Yamada?
A. Yes, this is a product sold by the Yamada Shuori Pillow Research Institute run by Yamada Shuori.
Q. Which is better: a 50cm x 25cm pillow or a wide 60cm x 30cm pillow?
A. In store sales, 80% of customers choose the wide size.
Once you experience it for yourself, you will probably feel that it is better to have a spacious and spacious room.
On the other hand, 50cm x 25cm pillows are selling well online.
Regarding the wide size, we believe that ``ease of turning over in bed'' is important, and we recommend it as it has been very popular with our large male customers.
Many women also choose it, and because it is long on the side, they often say it gives them a sense of security.
However, we do not believe that even if it is not a wide size, it is small enough to prevent you from turning over in bed, so you can choose the size according to your preference.
Q. What is the difference between the orthopedic pillow Doctor's Pillow and the waterproof orthopedic pillow Doctor's Pillow/deodorizing orthopedic pillow Doctor's Pillow?
A. The only difference is the pillow cover. The contents are exactly the same specifications.
Q. What is the difference between the "Doctor's Pillow by Orthopedic Surgeon Yamada Shuori" sold at bookstores and the orthopedic pillow Doctor's Pillow?
A. The "Doctor's Pillow by Orthopedic Surgeon Shuori Yamada" sold at bookstores is a product with quality and price for trial purposes only.
The concept of being able to adjust the height of the pillow yourself is the same, so we recommend it to customers who are hesitant to pick up the Orthopedic Pillow Doctor's Pillow from the beginning in terms of understanding the concept.
In terms of quality, the "Doctor's Pillow by Orthopedic Surgeon Shuori Yamada" sold at bookstores is made overseas and is 40cm wide, which is not enough for turning over in bed, but this is the limit of the book's size. ... apparently ...
The thickness of the material is also important, but there are large individual differences depending on the product. The orthopedic pillow doctor's pillow is assembled in Japan, and the minimum size is 50cm, which is considered necessary for turning over in bed.
Each piece is carefully assembled and each material is inspected for thickness and thickness.
Q. How long can I use the pillow?
A. If you follow proper usage instructions, you can use it for about 2 to 3 years. However, pillows are consumable items. Please perform appropriate maintenance and replace as necessary, depending on the deterioration of the material, changes in the user's body shape, and changes in the bedding environment.
3. Compatibility with futons and beds
Q.It's a hard pillow, but what kind of precautions do I need to take with the mattress or futon that I use it on?
A. The ease of turning over is the most important point.
For this reason, we recommend mattresses and futons with appropriate firmness. If the bedding is too soft, your body will bend in a dogleg shape and you won't have a fulcrum when turning over. Also, the entire body sinks and becomes unable to move.
Conversely, bedding that is too hard will put pressure on your lower back, causing your spine to arch and become tense. This makes your body tense and makes it difficult to sleep soundly.
For example, in a tatami room, we recommend using bedding that is as firm as an old-fashioned cotton futon and makes it easy to turn over.
However, it is a height-adjustable pillow, so if your mattress or futon has a certain level of firmness, you can often adjust the height of the pillow.
This image is part of the instruction manual and explains how to adjust the height of the pillow depending on the bedding.
Q. What does it feel like to be able to turn over easily?
A. If you are able to roll over easily, you will be able to turn your head to the right or left with ease.
