The "2 pillow rule" typically refers to a guideline suggesting that using two pillows can help maintain proper neck and spine alignment while sleeping. The idea is that one pillow supports the head while the second pillow, placed under the knees when lying on the back or between the knees when sleeping on the side, helps reduce pressure on the spine. This rule aims to improve sleep comfort and prevent neck and back pain.
