Learning About Posture and Body Mechanics During Pregnancy

What are posture and body mechanics and why are they important during pregnancy?

Posture is how you hold your body when you sit, stand, and move. Body mechanics is the way you use your body safely during daily activities. These include things like lifting, bending, carrying, and reaching. Good posture and safe body mechanics help protect your spine, hips, pelvis, and the muscles that support them.

Practicing good posture and body mechanics is important at any time in life. But it is especially important during pregnancy. Your body is changing quickly, and your joints and muscles are under more stress than usual.

How do good posture and safe movement help when you are pregnant?

Good posture and safe movement habits can reduce pain and discomfort throughout pregnancy. They lower the risk of injury to your muscles, joints, and nerves. Benefits also extend beyond delivery. Your ligaments and joints can stay relaxed for weeks to months after birth. Habits you build during pregnancy may help you recover faster and reduce the chance of ongoing pain.

What are some tips for safe movement in daily activities?

Here are some ways to move safely and protect your back as you do everyday activities.

  1. Lifting

    • When lifting an object, bend at your hips and knees rather than your waist. Keep your back as straight as you can. This protects your lower back.
    • Keep the object close to your body as you rise, using your leg muscles rather than your back. This helps reduce strain on your back.
    • Don't twist your body while lifting.

  3. Carrying

    • When you need to carry an item, split heavier loads into two smaller bags, one on each side.
    • Hold items close to your body.

    As your pregnancy progresses, ask for help carrying heavier items.

  5. Reaching

    • When reaching for an item on a high shelf, use a step stool.
    • Don't stretch or strain to reach for something above you.

  7. Getting up from lying down

    • When getting up from lying down, roll to your side first.
    • Then push up with your arms into a sitting position.

    This protects your belly (abdominal) muscles and reduces strain on your back.

How should you sit, stand, and sleep?

  1. Sitting

    • Sit in a chair with good back support.
    • Keep your feet flat on the floor or on a footrest. And keep your hips at a right angle. This helps keep your spine in a good position.
    • Tuck a small pillow or rolled towel behind your lower back (lumbar support) if the chair doesn't offer enough support.
    • Avoid crossing your legs for long periods, as it may affect your blood circulation or your posture.

  3. Standing

    • When standing, keep your knees slightly bent rather than locked. And keep your feet about shoulder-width apart. This reduces strain on your joints.
    • If you need to stand for long periods, rest one foot on a low step or stool. This can ease pressure on your lower back.

  5. Sleeping

  6. Side sleeping is generally recommended during pregnancy, especially after the first trimester. The left side is often suggested, but either side is safe.

    • Put a pillow between your knees. This can help align your hips and reduce back strain. You can also put a pillow under your belly for extra comfort.
    • Use a full-length body pillow for added support under your belly and behind your back.

    Lying flat on your back for long stretches after the first trimester is not typically recommended.

What self-care strategies help maintain good posture?

There are things you can do to help keep good posture. These tips may help.

  • Wear low-heeled, supportive shoes. High heels shift your weight forward and can increase lower back strain.
  • Use a maternity support belt to help carry some of the extra weight of your belly and relieve pressure on your back.
  • Adjust your workspace to be more comfortable. Raise your computer screen so that you aren't looking down. Use a chair with lumbar or low-back support. And be sure to take regular breaks. All these things can help reduce back strain over the course of the day.
  • Do exercises that help strengthen your core and back muscles. These include pelvic tilts, walking, swimming, and prenatal yoga. These may help ease discomfort over time. Always contact your doctor before starting a new exercise routine.
  • Use pillows to support your belly, back, and hips while sitting or resting.
