Bed rest was once a common recommendation to treat back pain, but its role in healing sore backs may be more limited than you think. Bed rest can give you a break from pain that flares up when standing or sitting too long, but too much rest may make it worse.
Staying in bed for a prolonged time can cause your muscles to lose strength and flexibility. While rest may make you feel better in the short term, but the loss of strength and flexibility can make your muscles stiffen and more likely to spasm. It’s best to keep your rest periods brief.
Rest on a firm bed or sofa in a comfortable position and keep pillows under your head. If you prefer lying on your back keep another pillow under your knees, or if you lie on your side keep it between your knees. The extra pillows help keep the spine properly aligned and reduce the stress on discs, ligaments, and muscles.
Whichever way you prefer to rest, it’s best to do so for no more than a few hours at a time, and for no longer than two days, preferably one. It’s important to resume normal range of motion activities as soon as possible, resting only as needed.
