Whether we like it or not, our society is becoming more and more sedentary by the day. The average work week for many Americans consists of sitting at a desk and working on a computer. This is compounded with an additional hour of sitting in the car during your commute, followed by watching several hours of TV or Netflix at the end of the day to unwind.
We are spending more time seated than any generation before us. What are the immediate and long-term health effects of sitting for long periods of time? Could these stresses be contributing to an overall worsening health? Are we in the midst of a sitting “epidemic”?
What are the Acute Health Effects of Sitting?
Every day at Life in Motion Chiropractic, we observe the affects of muscle imbalances due to sitting. Headaches, neck pain, shoulder pain, low back strains, and achy muscles are just a few of the conditions that can be directly tied to your current desk jockey’s posture.
Chronically tight “trap” (trapezius) muscles cause you to feel like the tops of your shoulders are hiked up to your ears. Chronically tight chest (pectoral) muscles develop because we’re always reaching for things down and in front of us. This presents as a forward, rounded shoulder appearance.
Weakened muscles in the front part of the neck cause the head to drift down and forward (allowing you to better view your phone or computer). This forward drift of the head will force muscles at the base of the skull to tighten, creating a nagging headache found at the base of your skull. This creates a snowball effect, as our head begins to drift further and further forward. Researchers have found that for every one inch forward your head moves, it adds an additional 10 pounds of stress to the muscles of the upper back and neck.¹
Sitting also requires little abdominal muscle activation, which results in a de-conditioned and weakened core. The weaker the core is, the more your spine must absorb your daily stresses and the more likely you are to injure the back from regular task. Something as common as bending forward to pick up a piece of paper or pen you dropped can cause the back to “go out”.
Long-Term Implications of Sitting
A study in 2005 published in the prestigious Spine Journal found that health measures such as breathing, heart rate, pain, and disability worsened with deteriorating posture.² The study further found that the worse the curve, the worse the health status markers.
Another study in 2004 followed 1,353 participants over the course of 3 years. They found that older men and women with larger curves in their mid back (hyper-kyphotic or “hunchback”) have higher mortality rates.³ We’re learning that these postural distortions may have health implications that reach far beyond tight muscles aches and pains. They may be preventing us from living a longer, more fulfilling life.
What Can We Do About It?
While some aspects of our posture are structural (bone positioning, length of muscles), a lot of our posture is learned. We recommend taking several small stickers and placing them around your work space in locations that are visible from your seat (at top of your computer monitor, on the cabinet drawer, etc). Throughout your work day, as your eyes wander around your space and land on these stickers, let it be a reminder to sit tall, roll your shoulders back, bring your chin to a neutral position, and breathe with your diaphragm through your stomach. These constant reminders can help you learn better posture.
Our office also has a great series of “Micro-Break” stretches that can be incorporated right from your desk. We recommend a 2-minute break every 30-minutes of work to performs these stretches and help combat the tight muscles.

Don’t be discouraged; Rome wasn’t built in a day. We can’t combat years of learned postural stresses by performing a few stretches once. The key to properly addressing these problems are regular breaks, stretching tight muscles, strengthening weaker muscles, and being aware of how you’re sitting.
If you’d like to learn more, please don’t hesitate to contact our office (734-427-6333) and schedule a FREE consultation where we discuss your personal working condition and how it may be affecting your health. We are also able to provide “Lunch n’ Learns” at your workplace, where we provide information on how to avoid injuries while you’re working.
