Lifting: Get close to the load and grasp firmly. Use your stomach muscles to support your spine so it can support the load. Maintain your three natural spinal curves as you use your leg muscles to lift the load. Set the load down smoothly.
Don't bend over with your legs straight or twist while you are lifting. Very important, too, is to avoid tying to lift objects above the height of your shoulders. Improper lifting can lead to facet syndrome and disc problems.
Standing/Walking:
Stand with one foot up and change positions often. Maintain your three natural spinal curves in their normal, balanced alignment. Walk with good posture, keeping your head high, chin tucked in, and toes straight ahead. Wear comfortable clothes and low-heeled shoes.
Don't stand in one place for a long time. Don't bend forward with straight legs or walk with poor posture. Avoid wearing high-heeled or platform shoes when you're standing or walking for any length of time. Postural syndrome can be the result.
Don't drive so that you are sitting in a slouched position with your three natural spinal curves out of their normal, balanced alignment. Postural and musculo-ligamentous syndromes could be the long-term result.
Don't sit in a chair that's too high or too far from your work. Avoid leaning forward for long periods with your back arched; also avoid slouching. Prolonged sitting in these positions can lead to a postural syndrome.
Driving:
Move your car seat forward to keep your knees bent and higher than your hips. Sit with your three natural spinal curves in alignment. Be sure the hollow of your back is fully supported. If not, use a small pillow. Drive with both hands on the wheel at all times.
Sitting:
Sit so you can place both your feet on the floor with your knees slightly higher then your hips. You can cross your legs or put your feet up on a stool or a footrest. Always sit firmly against the back of the chair with your lumbar spine supported by the cushion or a small pillow.
Sleeping:
A good night's sleep is good for you and your back. Use a firm mattress to support your spine's three natural curves. You can sleep on your side with your knees bent and a pillow between your knees. Or lie on your back with a pillow under your knees. Don't sleep or lounge on soft, sagging, nonsupporting mattresses or cushions. The habit of sleeping on your stomach can cause further back strain. Sleeping without supporting your back properly can lead to postural and musculo-ligamentous syndromes.
