Why Use a Knee Pillow?

Sleeping pain free

Many experts who have studied sleep will tell you that most people sleep on their side. While it provides the best support for your spine’s natural curve, not everyone can sleep pain free in that position.

This is where knee pillows come in. It does the following two things

  • Reliefs hip pressure
  • Supports the spine

Aiding the position by providing support between the knees, better spinal alignment and relief to the sciatic nerve.

Many users of knee pillows report an amazing increase in a better night’s sleep.

For side sleepers

The Mayo Clinic is one of the highly reputable institutions that recommends the use of a knee pillow if you choose to sleep on your side.

Improve sleep quality

Another great reason to use a knee pillow is that it is a natural solution. Many people, frustrated with their lack of quality sleep, turn to medicinal sleeping aids that can become addictive over time and eventually ineffective, leaving them with reduced relief and the prospect of taking more and more medication to sleep well.

The purchase and use of a knee pillow is a great, drug-free way to naturally align your spine and provide relief to sore and aching joints.

If you are a side sleeper that would love to​ support your spine better but hate the knee pillow, worry not! 

there is another pillow that does the same thing as the knee pillow. So check out the best body pillows if you don't like this pillow.

How Does a Knee Pillow Work?

Knee pillows are incredibly popular because of how they work to help our bodies while we sleep. When it comes to sleeping, the muscles in our body become sore when they have pressure applied to them.

Without any support, the pelvis rotates and allows the spine to slip out of alignment. This can lead to pain and discomfort.

When you place a knee pillow properly between the knees before falling asleep on your side, the pillow will ensure that your spine is aligned and that pressure is relieved from the muscles and nerves.

Knee Pillow Demonstration

Many people who sleep with a knee pillow report a drastic reduction in the amount of pain they experience and that the quality of their sleep improves dramatically.

While your results may vary, taking the time to research the knee pillow that works best for you is essential. You may need to take into consideration your height, weight, age, medical condition and other factors when making a choice.
