Standing Tall: Why Posture Matters
Remember how your mom used to always lecture you to stand up straight? Well, she might have made some mistakes over the years (that outfit in your 5th grade school picture), but on this one, she’s right. Posture matters more than you may think.
First, let’s talk about your body, starting at the top. Each inch your head is forward of your shoulders doubles the amount of weight it puts on the rest of your body. Although the average head only weighs between 8-10 pounds, your upper back (and then lower back and hips) will become misaligned if your head “lives” in a forward position – all in an attempt to balance your now-too-heavy head.
And, unless you sit in an ergonomically perfect workstation, chances are you round forward over your keyboard or laptop like something straight out of the latest episode of the “Walking Dead.” Most of us, sadly, are in the process of developing this posture. Blame the Internet (we’re talking to you, Mark Zuckerberg) or your boss (for making you work too much).
What happens to our bodies? Back pain, neck pain, hip pain and knee pain. And, let’s not forget your breathing. Collapsing forward compresses your lungs, reducing their capacity by 30 percent or more. Your organs can’t function properly, and neither can your muscles, joints, or connective tissue.
Posture also matters for your mental health. Good posture allows you to breathe more fully, calming your nervous system, which can help with everything from good sleep to good moods. Plus, standing up tall makes you feel more confident. Slouching pulls your energy downward, even making walking and balance more difficult.
What to do? First, analyze your own posture. Do your shoulders slouch? Is your head forward? Do you have back or neck pain? When you walk do you have a tendency to lean forward and feel like you’re lifting your knees towards you?
Since it is vital to have extension in the upper torso in standing posture, the starting place is simply awareness of how you’re standing or sitting. Imagine lifting out of your pelvis, shoulders back, head looking slightly above the horizon.
Don’t spend too much time sitting at your desk, especially in bad posture. Take a walk. Inhale your arms overhead and slightly back. Regularly engage your lower trapezius to draw your shoulders away from your ears, and your rhomboids to draw your shoulders together.
And balance the forward posture with a lot of back bends. Stretch your pecs and anterior shoulder muscles with anahatasana pose (think child’s pose with your hips over your heels, reaching your tailbone and chest away from each other). Camel pose has been called the “antidote to sitting” because it stretches the entire front of your body.
If you have access to a Pilates reformer, you’re in luck. Do seated arm circles to take your shoulders through a weighted stretch, and turn around for chest expansion to, well, expand your chest and your lung capacity. Or just lie down on a mat, extending arms and legs long on the floor, and lift up, fluttering arms and legs in opposition while breathing deeply.
Most importantly, throughout your day, remember to stand up straight. Don’t slouch. Just listen to mom on this one. You can still argue about your clothes, your politics, and what’s for dinner. On posture, she’s right.
Yoga Anatomy: Reducing Shoulder Impingement
Our wonderful shoulders are the most mobile joints in the body and, for anyone who has done any amount of Hatha Yoga flow, we can appreciate how much the shoulders are engaged and challenged in our practices. Given how frequently we load and stress the shoulders in yoga, it is ideal to move the shoulders with intelligence, mindfulness, and attentive care. One aspect of mindful movement and engagement is reducing the onset of shoulder impingement.
Our shoulder joints are made from a ‘ball and socket’ design. The upper arm bone (humerus) has defined structures at its proximal end (closest point to the center of the body). At the proximal end of the shaft, we see that the humerus has boney processes (called tubercles where tendons attach). Moving towards the shoulder joint, the humerus has a neck that transitions into a ‘head’ or the ball portion of the joint. The humeral head inserts into the socket (glenoid fossa or cavity) forming this highly moveable joint. The socket is part of the shoulder blade (scapula bone). There is another part of the shoulder blade with a boney projection called the acromion process which is positioned above the humerus. You call feel the acromion process on yourself by taking one hand over and to the back of the shoulder blade. Run your fingers along the shoulder blade to find a horizontal line of bone – this the spine of the scapula. Run your fingers all the way to the end into your shoulder – where this ends is your acromion process.
Between the acromion process and the tubercle region of the humerus is the ‘subacromial space.’ This is where our attention goes regarding shoulder impingement considerations. Deep above the spine of the scapula runs one of your rotator cuff muscles (supraspinatus muscle), which has its tendon traveling through the subacromial space and attaching onto the greater tubercle of the humerus. To offer some protection to this tendon, there is a small sac of fluid (bursa sac) between the tendon and the acromion process.
When we stand in Mountain pose (arms relaxed), there is ample space in the subacromial space for the supraspinatus tendon and the bursa sac. When we lift our upper arm bone outwards (abduction) or towards certain angles of significant forward movement (flexion), the humerus closes into the subacromial space. For some people, due to bone structure and reduced subacromial space, they are more prone to having the tendon and/or bursa sac being compressed and stressed (aka shoulder impingement). With frequent compression, the tendon and/or bursa sac may develop conditions of inflammation. As with any acute or chronic development of shoulder impingement conditions, you will want to consult a qualified health professional for proper assessment and therapeutic treatment.
