Benefits and Side Effects of a Buckwheat Pillow You Need to Know

Updated April 10, 2021

A buckwheat pillow, otherwise known as a Sobakawa, is a traditional Japanese pillow filled with the hulls that encase buckwheat seeds. They are springy under compression but provide a firm, contouring support that supports proper rest of your head and neck positioning. Because they claim to ease tension and strain through spinal alignment, they have become popular sleep support aides for anyone looking for a good night’s rest. The benefits and side effects of a buckwheat pillow are fairly simple due to their simple design, and I’ve provided a quick guide below so you can better determine whether or not it is a product you may want to consider.

Our Editor’s choice:

As with many types of pillows, not all buckwheat pillows are created equal. The Zen Chi Buckwheat pillow is a particularly well-reviewed option that gets extra credit on account of its use of organic buckwheat filling, plus the fact that you can personally tailor its firmness to suit your sleeping preferences. By adding or removing buckwheat hulls from the pillow its firmness is infinitely variable, meaning you no longer have to play that frustrating guessing game of whether or not you need to purchase a medium, firm, or extra firm pillow. Word to the wise, keep some extra buckwheat hulls around as spares, as they have a tendency to settle/compress a little bit after the first couple of weeks of use.

What is Buckwheat?

Buckwheat is a seed-like grain native to Asia. For centuries, it has been a staple for both feeding domestic animals as well as its use for human consumption. This seed is actually considered a fruit and grows within a husk – a shell-like casing that protects the seed as it matures. This part of the plant is inedible, but it was utilized in other ways, one being a long-lasting, durable filling for pillows and mattresses. Today, buckwheat is grown on many continents as its nutritional benefits and hull use has spread far and wide. Pillow companies have added the benefits of buckwheat products to their offers, making them more widely known and more readily available. The seeds are removed from the hulls, and then the hulls are cleaned and used within a material casing. Usually, these cases are made from natural fibers such as cotton and silk and are adjustable to add, remove, or refresh your hulls throughout the life of the pillow (which can be rather long)!

The Benefits of a Buckwheat Pillow

The benefits and positive side effects of a buckwheat pillow may differ from person to person but are substantiated by the thousands of consumers who have found pain relief and comfort with the regular use of the pillow. Since we’ve personally reviewed few pillows ourselves and researched other quality choices, we can honestly say this is a pillow worth taking a closer look at.

Better Sleep

First and foremost, buckwheat pillows have become a popular sleep product since they truly do support proper posture and spinal alignment. When on your back and stomach, you need a thin pillow that holds your head level between your shoulders and also provides support to the gap created by the arch of your neck. Side sleepers need to hold their head high and between their shoulders and also have a proper material fill to fill the gap between their head and shoulders.

A buckwheat pillow is malleable and non-shifting to allow for a contouring to your unique body shape and comfort needs. It helps to allow the important cervical alignment, and when this positioning is achieved, your body is better able to relax and rest through the sleep stages uninterrupted.

Reduced Snoring

Many people who snore do so because of poor sleep posture. Although this pillow does not claim to solve all your snoring problems, especially if you suffer from sleep apnea, it can influence a better posture to allow your airways to be kept open through the night.

If your neck muscles are unable to relax through the night due to poor support or your head is held too high or is allowed to fall too far back, then you may compromise your airway which can lead to snoring. Your airway runs along your cervical spine, and by keeping your spine aligned, you also support your airways. If you suffer from disruptive snoring that is not affected by changes in your posture, you should always check with a doctor for any underlying causes.

Muscle Support

The leading cause of neck and back pain that is not associated with injury or illness is poor sleep posture. As explained, a buckwheat pillow can help support your head and neck in the correct position to support your spine and allow true relaxation. Your muscle and other soft tissues will work to keep your spine aligned- after all, your spine is the main support of your central nervous system from which your entire body functions. These muscles, ligaments, and tendons can become fatigued through the night and will attempt to compensate for one another – leading to uncomfortable pain and tenderness. Without adjustment and care over time, these types of stressors can lead to headaches and sleeplessness amongst other things.

 

Promotes Airflow for a Cooler Sleep

These pillows do more than just support your personal airways, they also promote airflow of the product itself to provide you with a cooler night’s sleep. Buckwheat hulls are slightly cupped, triangular in shape, smooth, and thus create thousands of tiny air pockets between them. They never compress and only fit more closely together when weight is applied. They also do not radiate or hold heat, making them an ideal filling for anyone who sleeps hot.

May Aide in Migraine Relief

There are many studies behind the causes of migraines- some concentrate on spinal alignment, soft tissue strain, airway support, and pressure points. The cause of migraines may be varied from person to person, but there have been many reports of a reduction of incidences and relief through the use of a buckwheat pillow. This is mainly due to how well it supports soft tissues and airways, as well as providing soft pressure against specific points along your neck and skull. These pressure points help trigger relaxation through the regulation of blood through the brain and a release of endorphins – a feel-good hormone.

 

Hypoallergenic and Dust Mite Resistant

There are no materials that are considered a food source in the construction of these materials. This means they do not attract bugs or insects, and nor are they a likely environment for allergens to collect. They are considered a hypoallergenic and dust mite resistant choice since they provide excellent airflow- which is not conducive to these aforementioned issues. If you are very sensitive to certain plants, especially those used for animal consumption, you may want to check with your doctor despite there being little to few reports of true buckwheat allergies.

 

Long Lasting

Buckwheat pillows, on average, can be used up to 10 years with proper care. This is often determined by the quality and thickness of the material used, as the hulls can wear against the thin material through consistent friction over time. Well sewn seams and heavy-duty zippers help hold in hulls, and they need to be durable enough to resist against the heft of the hulls (as these pillows can be very heavy). The hulls themselves can begin to wear down too with use, but if you have an adjustable pillow, you can easily refresh them with the purchase of a bag of hulls made specifically for this reason. This makes them both environmentally friendly as well as economical!

Adjustable

Mentioned above, many of these pillows provide adjustability, meaning you can add to or remove hulls to fit your comfort needs. This is especially important for the proper placement of your head and neck, and the fact that our body is not made exactly the same, the pillows will offer different specific needs. A higher pillow is generally needed by side sleepers, whereas thinner choices are needed for back and stomach. Stomach sleepers, in particular, need a practically non-existent lift and being able to remove hulls for this purpose allows them to be a popular pick for a wider variety of sleepers. Just be aware that not all companies provide this choice.

Most buckwheat hulls harvested for pillow use are organically sourced, ensuring you are not exposed to any chemical or pesticide processes. They also almost always use a 100% cotton or organic material source for their casings, making them a possible vegan choice as well. Since the construction is simple, most of these companies that manufacture them are considered more environmentally friendly than others.

The Cons (or Are There Any?) of a Buckwheat Pillow

There truly aren’t many cons of a buckwheat pillow. The worst problem you may run into is a pillow that is of poor quality that doesn’t last long during prolonged use, and that can easily be avoided through the proper research of a company and their products. Though, there are a few things to consider before making an investment in these types of pillows since they do not follow a conventional design. They easily are not easily found or sold on store shelves and almost always need to be ordered.

Takes Some Time to Get Used To

Buckwheat hulls are much different than the softer fibers, feathers, and foams used as stuffing in most pillows. They can provide cushioning and contouring, but are too stable to feel and do not shift with your body – rather it holds you in place.  Most people state to give yourself about 5 days to get used to (which we’ll corroborate). Any adjustable pillow type does require some trial and error before finding the exact fill amount to fit your comfort needs. This takes patience and may even result in a few nights of not-quite-so-comfortable sleep until you find the perfect fit for you. Fans of adjustable pillows claim this is well worth the effort, however, as you’ll end up basically with a customized pillow.

Natural Odor

Buckwheat has a natural earthy smell that is considered aromatic and calming. It may be a strong smell upon opening due to storage techniques, or it can’t be noticeable at all if the hulls have ever been roasted when being prepared for consumers. Some consumers do not find it pleasant, although it does air out and dissipate easily.

Rustling Noise

The hulls do create a slight rustling and crunching noise when moved and laid upon. It is fairly muted and easy to get used to over time, but it can be slightly distracting until you get used to it in your everyday routine. Since your head is held in place, the noise is not as noticeable once you’re sleeping on the pillow, but it can be otherwise if you are a restless sleeper. The good thing is that the pillow is easily shapeable, and you can create the indents you need to rest your head and support your neck and shoulders when needed.

Not Washable (Cases Are!)

Do not wash buckwheat! Even though it does not really absorb water well, it can ruin the strength of the hulls and allow them to weaken and be less durable. Plus, it is very heavy (more on that below) and will probably throw your washer out of balance permanently. Removable casings are washable, however, and should be washed regularly according to the manufacturer’s directions.

Heavy

These pillows are heavy – as in up to 12 pounds heavy. They are not made to be the pillow you prop up to lean against for television watching as gravity will drag the hulls to the bottom of the casing. They also are not for pillow fights unless you are truly trying to defend yourself. Rather, they are made to hold still and not shift to provide the proper body placement you need.

Conclusion

The benefits and side effects of a buckwheat pillow are varied and well worth the consideration. They are comforting and have a myriad of benefits that can help support your overall health. Although they may take a bit of getting used to, most consumers state within 3 to 5 days they have its use all figured out, and the noise is no longer even noticeable to them. With claims to help provide proper posture, headache-and-migraine relief, and reduce snoring, this is definitely worth considering to help you get a proper night’s rest.
