Prevention

You might avoid back pain or prevent its recurrence by improving your physical condition and learning and practicing proper body mechanics.

To keep your back healthy and strong:

• Exercise. Regular low-impact aerobic activities — those that don't strain or jolt your back — can increase strength and endurance in your back and allow your muscles to function better. Walking and swimming are good choices. Talk with your doctor about which activities you might try.
• Build muscle strength and flexibility. Abdominal and back muscle exercises, which strengthen your core, help condition these muscles so that they work together like a natural corset for your back.
• Maintain a healthy weight. Being overweight strains back muscles. If you're overweight, trimming down can prevent back pain.
• Quit smoking. Smoking increases your risk of low back pain. The risk increases with the number of cigarettes smoked per day, so quitting should help reduce this risk.

Avoid movements that twist or strain your back. Use your body properly:

• Stand smart. Don't slouch. Maintain a neutral pelvic position. If you must stand for long periods, place one foot on a low footstool to take some of the load off your lower back. Alternate feet. Good posture can reduce the stress on back muscles.
• Sit smart. Choose a seat with good lower back support, armrests and a swivel base. Placing a pillow or rolled towel in the small of your back can maintain its normal curve. Keep your knees and hips level. Change your position frequently, at least every half-hour.
• Lift smart. Avoid heavy lifting, if possible, but if you must lift something heavy, let your legs do the work. Keep your back straight — no twisting — and bend only at the knees. Hold the load close to your body. Find a lifting partner if the object is heavy or awkward.

Buyer beware

Because back pain is so common, numerous products promise prevention or relief. But there's no definitive evidence that special shoes, shoe inserts, back supports, specially designed furniture or stress management programs can help.

In addition, there doesn't appear to be one type of mattress that's best for people with back pain. It's probably a matter of what feels most comfortable to you.
