Sciatica pain is known to disrupt sleep cycles. The pain can make it hard to find a comfortable sleeping position. Here’s how different sleep positions can affect sciatica pain:

• Sleeping on your Stomach: Sleeping on your stomach can worsen sciatica pain because it flattens the natural curve of the spine which adds additional strain to the lower back. 
• Sleeping on Your Back with a Pillow Under Knees: This position helps to maintain the natural curve of the spine. Sleeping in this position helps to reduce pressure on the sciatic nerve.
• Reclined Position: Sleeping in a reclined position can help to reduce pressure on the spine.
