What is a one-sentence summary of the following article?
Your surgeon may have ordered you to wear a neck collar or brace. Follow the surgeon's guidelines for when to wear it. Some people may find it more comfortable to sleep or nap in a recliner, especially when the collar or brace is on. The best sleeping position post-surgery is on your back. Keep your head, neck, and hips aligned as you lie on your back so your body is well supported. Some people find it more comfortable to bend their legs and place their feet flat on the bed when they are lying on their back. Another option is to sleep on one side. Bend your legs when you sleep on your side for added comfort.  Do not sleep on your stomach, as this can strain your neck.  A sleep position on your back or side is a safer option. Make sure the pillow is not too flat or high, as you do not want your neck to sink below your shoulders or be at an angle up from your shoulders. Check that the pillow keeps your neck in line with your spine, rather than twisted to one side. A pillow made out of foam can give your head and neck more support as you recover. If you are sleeping on your back, slide a pillow or a rolled up towel under your legs to better support your back. If you are sleeping on your side, you can put a pillow between your legs to support your back and chest. If you tend to put your arms under your head or one knee up when you sleep on your side, place a pillow behind your back and hips to prevent rolling out of a side sleeping position. Make sure your arms lay on either side of you or curled below your head and neck. This will ensure your neck and shoulders are not strained while you sleep. You may find placing a heavy blanket over your body when you sleep can help to keep your arms from shifting or moving in the night.

Summary:
Follow instructions if your doctor recommends a collar or brace. Sleep on your back to protect your neck and spine. Try sleeping on your side if you find it hard to lie on your back. Place a pillow under your head for support. Use a pillow between or under your legs for added comfort. Keep your arms below your head and neck.
