• Keep your feet on the floor or on a footrest, if they don't reach the floor.
• Don't cross your legs. Your ankles should be in front of your knees.
• Keep a small gap between the back of your knees and the front of your seat.
• Your knees should be at or below the level of your hips.
• Adjust the backrest of your chair to support your low- and mid-back or use a back support.
• Relax your shoulders and keep your forearms parallel to the ground.
• Avoid sitting in the same position for long periods of time.
How do I stand properly?
• Bear your weight primarily on the balls of your feet.
• Keep your knees slightly bent.
• Keep your feet about shoulder-width apart.
• Let your arms hang naturally down the sides of the body.
• Stand straight and tall with your shoulders pulled backward.
• Tuck your stomach in.
• Keep your head level-your earlobes should be in line with your shoulders. Do not push your head forward, backward, or to the side.
• Shift your weight from your toes to your heels, or one foot to the other, if you have to stand for a long time.
What is the proper lying position?
• Find the mattress that is right for you. While a firm mattress is generally recommended, some people find that softer mattresses reduce their back pain. Your comfort is important.
• Sleep with a pillow. Special pillows are available to help with postural problems resulting from a poor sleeping position.
• Avoid sleeping on your stomach.
• Sleeping on your side or back is more often helpful for back pain.
• If you sleep on your side, place a pillow between your legs.
• If you sleep on your back, keep a pillow under your knees.
