Posture for a Healthy Back
Posture is the position in which you hold your body upright against gravity while standing, sitting or lying down. Good posture involves training your body to stand, walk, sit and lie in positions where the least strain is placed on supporting muscles and ligaments. Proper posture:
- Keeps bones and joints in the correct alignment so that muscles are being used properly.
- Helps decrease the abnormal wearing of joint surfaces that could result in arthritis.
- Decreases the stress on the ligaments holding the joints of the spine together.
- Prevents the spine from becoming fixed in abnormal positions.
- Prevents strain or overuse problems.
- Prevents backache and muscular pain.
Proper Posture Requirements
Make sure you use proper posture practices throughout your day. Follow the guidelines listed below to ensure the health of your back.
- Sit up with your back straight and your shoulders back. Your buttocks should touch the back of your chair.
- All, three normal back curves should be present while sitting. A small, rolled-up towel or a lumbar roll can be used to help you maintain the normal curves in your back. Here's how to find a good sitting position when you're not using a back support or lumbar roll:
- Sit at the end of your chair and slouch completely.
- Draw yourself up and accentuate the curve of your back as far as possible. Hold for a few seconds.
- Release the position slightly (about 10 degrees). This is a good sitting posture.
- Distribute your body weight evenly on both hips.
- Bend your knees at a right angle. Keep your knees even with or slightly higher than your hips. (Use a foot rest or stool if necessary.) Your legs should not be crossed.
- At work, adjust your chair height and work station so you can sit up close to your work and tilt it up at you. Rest your elbows and arms on your chair or desk, keeping your shoulders relaxed.
- When sitting in a chair that rolls and pivots, don't twist at the waist while sitting. Instead, turn your whole body.
Correct Driving Position
- Use a back support (lumbar roll) at the curve of your back. Your knees should be at the same level or higher than your hips.
- Move the seat close to the steering wheel to support the curve of your back. The seat should be close enough to allow your knees to bend and your feet to reach the pedals.
Correct Lifting Position
- To pick up an object that is lower than the level of your waist, keep your back straight and bend at your knees and hips.
- Stand with a wide stance close to the object you are trying to pick up and keep your feet firm on the ground. Tighten your stomach muscles and lift the object using your leg muscles. Straighten your knees in a steady motion.
- Stand completely upright without twisting. Always move your feet forward when lifting an object.
- To lower the object, place your feet as you did to lift, tighten stomach muscles and bend your hips and knees.
