Elevating the legs helps to alleviate pressure on the veins, which can improve blood flow and reduce swelling. Furthermore, this pillow can assist in conditions like sciatica by decreasing nerve pressure in the lower back area.
Best practices for choosing an under-knee pillow include selecting the right height and material to suit individual needs. Back sleepers should look for pillows that are specifically marketed for this purpose, ensuring they provide adequate support without being too firm or too soft. Regularly assessing the pillow for wear and replacing it when necessary can also help maintain its effectiveness.
