Research suggests that 30 to 45 minutes of low-intensity aerobic exercise (such as brisk walking) five or six days a week is your best bet — and even four days of exercise a week will have some effect.

Before you start a new exercise program, however, talk to your health care professional if you're older than age 40, have been sedentary, have risk factors for coronary heart disease, or have chronic health problems. If you have pain from an injury, recent surgery, a physical disability, or a chronic condition such as osteoporosis, it's best to work with a physical therapist or exercise physiologist to be sure you can exercise safely and avoid hurting yourself.

• Get enough sleep

Pain, and some pain-related medications, can interfere with sleep. You might find it difficult to fall asleep, or you may wake up during the night. On the opposite end of the spectrum, some pain medications can cause fatigue and make you want to sleep the day away. Getting a proper amount of sleep is important because sleep helps you cope with your pain by boosting your energy levels and your mood.
