Is your back hurting this morning? This could be why.
There are several factors that go into choosing pillows, aside from just taste and preference, and you'll want to replace them when they start to wear out, Lees notes. But while you may be tempted to grab an extra pillow for more support, that may not be the best strategy to keep your neck and back in check.World_of_Textiles / Shutterstock
While there is no official rule about how many pillows you should sleep with, experts generally agree that sleeping with more than one under your head can actually hurt your neck and back. And in fact, one supportive pillow is really all you need to keep your body aligned and your neck in a supported position.
"While using multiple pillows might feel comfortable when you first lay down, sleeping for eight hours with your neck flexed forward or to the side can put a ton of stress on the muscles, ligaments, and discs in your cervical spine,", says."This is a major cause of neck pain, shoulder pain, and tension headaches."
If you have unnecessary memory foam or feather pillows on your bed while you sleep, they can create further problems for your sleep hygiene."Too many pillows may shift throughout the night and can become a hindrance during sleep," Lees adds.
