How Bad Knee’s Posture Contributes to Back Pain & Poor Sleep
Many people struggle to sleep at night due to upper or lower back pain. This results from having bad posture for an extended period and will put your spine out. Knee pillows can help ease this pain by providing proper spinal alignment and reducing pressure on the affected areas.
The back pain will only worsen as time passes, often putting excess pressure on the hips, neck, and shoulders.
If even more time goes by, this back pain can evolve into a terminal condition, such as sciatica, spondylolisthesis, or scoliosis. Knee pillows can help ease the symptoms of these conditions by providing proper spinal alignment and reducing pressure on the affected areas.
A back out of alignment can also block blood flow, especially when sleeping on your side.
When your knees touch, they can block the blood flow if your hips are out of alignment and cause pain, resulting in a lack of sleep.
This can also result in swelling or conditions such as Edema. Symptoms of Edema include swelling in the ankles or hips and joint pain.
Why Knee Pillows Are Essential for Back Pain Relief & Better Sleep
Investing in a knee pillow is a proactive step towards maintaining good posture and preventing the progression of back pain. By choosing the right knee pillow, you can take control of your sleep and health, potentially avoiding future medical bills.
Medical experts also highly recommend knee pillows for Edema and pregnant women. For Edema, we suggest the Pull-On Knee Cushion, which can elevate your feet and prevent swelling in the ankles. For pregnant women, the Back Support Systems DLX Knee Pillow is ideal, as it provides better back support to compensate for the extra weight in utero.
Knee pillows help support your hips if you sleep on your side by providing a layer of cushioning between the knees.
Other types of knee pillows, inserted under the knees, can elevate your feet. These are particularly great if you suffer from pitting Edema or swelling in the ankles.
These medical pillows prevent blocked blood flow and ease lower and upper back pain. A knee pillow is also indicated for herniated discs or problems from a pinched nerve.
Characteristics of a Good Knee Pillow
- Spacing – The best knee pillow should provide enough spacing between your knees so your back is straight and your knees don’t knock against each other. It should allow for proper blood flow to your feet and be a comfortable match.
- Memory Foam – is the best material to look for in a knee pillow as it retains your shape while it’s warm (such as from body heat) and loses the impression when colder. This gives the ultimate flexibility topped with maximum comfort. Memory foam is the most healthy pillow material with minimal allergens or contaminants.
- Other Materials – Some materials, such as latex, polyester, water, down feathers, and sometimes even buckwheat hulls, can be made. Latex and polyester provide allergenic reactions in some people but are usually the most affordable options.
The NHS advises seeing a GP if hip pain stops you doing normal activities or affects your sleep, or has not improved after 2 weeks of treating it at home.[1]
For back pain, the NHS advises staying as active as possible and not staying in bed for long periods, and notes that walking, swimming, yoga and pilates may help.[2]
