The benefits of good posture - Murat Dalkilinç

  • 0:08 - 0:11
    Has anyone ever told you,
    "Stand up straight!"
  • 0:11 - 0:15
    or scolded you for slouching
    at a family dinner?
  • 0:15 - 0:19
    Comments like that might be annoying,
    but they're not wrong.
  • 0:19 - 0:23
    Your posture, the way you hold your body
    when you're sitting or standing,
  • 0:23 - 0:26
    is the foundation for every movement
    your body makes,
  • 0:26 - 0:31
    and can determine how well your body
    adapts to the stresses on it.
  • 0:31 - 0:34
    These stresses can be things
    like carrying weight,
  • 0:34 - 0:36
    or sitting in an awkward position.
  • 0:36 - 0:41
    And the big one we all experience
    all day every day: gravity.
  • 0:41 - 0:43
    If your posture isn't optimal,
  • 0:43 - 0:47
    your muscles have to work harder
    to keep you upright and balanced.
  • 0:47 - 0:50
    Some muscles will become tight
    and inflexbile.
  • 0:50 - 0:52
    Others will be inhibited.
  • 0:52 - 0:54
    Over time, these dysfunctional adaptations
  • 0:54 - 0:59
    impair your body's ability
    to deal with the forces on it.
  • 0:59 - 1:03
    Poor posture inflicts extra wear and tear
    on your joints and ligaments,
  • 1:03 - 1:05
    increases the likelihood of accidents,
  • 1:05 - 1:10
    and makes some organs,
    like your lungs, less efficient.
  • 1:10 - 1:12
    Researchers have linked
    poor posture to scoliosis,
  • 1:12 - 1:14
    tension headaches,
  • 1:14 - 1:15
    and back pain,
  • 1:15 - 1:19
    though it isn't the exclusive
    cause of any of them.
  • 1:19 - 1:22
    Posture can even influence
    your emotional state
  • 1:22 - 1:24
    and your sensitivity to pain.
  • 1:24 - 1:28
    So there are a lot of reasons
    to aim for good posture.
  • 1:28 - 1:30
    But it's getting harder these days.
  • 1:30 - 1:34
    Sitting in an awkward position
    for a long time can promote poor posture,
  • 1:34 - 1:37
    and so can using computers
    or mobile devices,
  • 1:37 - 1:39
    which encourage you to look downward.
  • 1:39 - 1:44
    Many studies suggest that, on average,
    posture is getting worse.
  • 1:44 - 1:46
    So what does good posture look like?
  • 1:46 - 1:49
    When you look at the spine
    from the front or the back,
  • 1:49 - 1:53
    all 33 vertebrae should appear stacked
    in a straight line.
  • 1:53 - 1:56
    From the side, the spine
    should have three curves:
  • 1:56 - 2:01
    one at your neck, one at your shoulders,
    and one at the small of your back.
  • 2:01 - 2:03
    You aren't born with this s-shaped spine.
  • 2:03 - 2:07
    Babies' spines just have one curve like a "c."
  • 2:07 - 2:10
    The other curves usually develop
    by 12-18 months
  • 2:10 - 2:13
    as the muscles strengthen.
  • 2:13 - 2:16
    These curves help us stay upright
    and absorb some of the stress
  • 2:16 - 2:19
    from activities like walking and jumping.
  • 2:19 - 2:21
    If they are aligned properly,
  • 2:21 - 2:22
    when you're standing up,
  • 2:22 - 2:24
    you should be able to draw a straight line
  • 2:24 - 2:26
    from a point just in front
    of your shoulders,
  • 2:26 - 2:28
    to behind your hip,
  • 2:28 - 2:29
    to the front of your knee,
  • 2:29 - 2:32
    to a few inches in front of your ankle.
  • 2:32 - 2:36
    This keeps your center of gravity
    directly over your base of support,
  • 2:36 - 2:38
    which allows you to move efficiently
  • 2:38 - 2:41
    with the least amount of fatigue
    and muscle strain.
  • 2:41 - 2:44
    If you're sitting,
    your neck should be vertical,
  • 2:44 - 2:45
    not tilted forward.
  • 2:45 - 2:49
    Your shoulders should be relaxed
    with your arms close to your trunk.
  • 2:49 - 2:54
    Your knees should be at a right angle
    with your feet flat on the floor.
  • 2:54 - 2:56
    But what if your posture isn't that great?
  • 2:56 - 2:59
    Try redesigning your environment.
  • 2:59 - 3:04
    Adjust your screen so it's at
    or slightly below eyelevel.
  • 3:04 - 3:06
    Make sure all parts of your body,
  • 3:06 - 3:09
    like your elbows and wrists,
    are supported,
  • 3:09 - 3:12
    using ergonomic aids if you need to.
  • 3:12 - 3:14
    Try sleeping on your side
    with your neck supported
  • 3:14 - 3:17
    and with a pillow between your legs.
  • 3:17 - 3:20
    Wear shoes with low heels
    and good arch support,
  • 3:20 - 3:22
    and use a headset for phone calls.
  • 3:22 - 3:26
    It's also not enough
    to just have good posture.
  • 3:26 - 3:30
    Keeping your muscles and joints moving
    is extremely important.
  • 3:30 - 3:34
    In fact, being stationary for long periods
    with good posture
  • 3:34 - 3:39
    can be worse than regular movement
    with bad posture.
  • 3:39 - 3:41
    When you do move, move smartly.
  • 3:41 - 3:44
    Keep anything you're carrying
    close to your body.
  • 3:44 - 3:49
    Backpacks should be in contact
    with your back carried symetrically.
  • 3:49 - 3:52
    If you sit a lot, get up and move around
    on occassion,
  • 3:52 - 3:55
    and be sure to exercise.
  • 3:55 - 3:58
    Using your muscles will keep them
    strong enough to support you effectively,
  • 3:58 - 4:04
    on top of all the other benefits
    to your joints, bones, brain and heart.
  • 4:04 - 4:07
    And if you're really worried,
    check with a physical therapist,
  • 4:07 - 4:11
    because yes,
    you really should stand up straight.
