Sciatica is a very painful condition. Paying attention to some details when resting and sleeping can alleviate sciatica to a certain extent. Specifically, the first point is to sleep on a hard bed, preferably a solid wooden bed. If the bed is too soft, consider placing a wooden board on it. Second, lying on your back is better than lying on your side. This is because lying on your back can maintain the stability of the lumbar spine, thereby reducing the pressure on the discs. Third, maintain a moderate flexion of the hips and knees while sleeping. To do this, place a small soft pad under the lower back and a small soft pillow under the knee joints to keep the hip joints in a slightly flexed position. The purpose is to let the muscles of the lower back relax optimally, thus stabilizing the lumbar spine and reducing the burden on the lumbar discs. Therefore, for sciatica, if you sleep on a harder bed in a supine position, and maintain proper knee and hip flexion, it can be very beneficial for recovery.
