Success in Your Spine
The human body is an amazingly complex system of bones, joints, muscles, and nerves, designed to work together to accomplish one thing: motion. Remember that motion is life. Everything about the human body is designed with motion in mind: nerve fibers stimulate the muscles to contract, muscles contract to move the bones, bones move around joints, and the nerve system controls it all.
As a matter of fact, research has shown that motion is so critical to our body's health that a lack of motion has a detrimental affect on everything from digestion to our emotional state, immune function, our ability to concentrate, how well we sleep and even to how long we live. If your lifestyle does not include enough motion, your body cannot function efficiently. First, you will not be as physically healthy and will suffer from a wide variety of physical ailments, ranging from headaches to high blood pressure. Second, you will not be as productive in your life because of reduced energy levels and the lack of ability to mentally focus. Third, because you have less energy, your activity level will tend to drop off even further over time, creating a downward spiral of reduced energy and less activity until you get to a point where even the demands of a sedentary job leave you physically exhausted at the end of the day.
The human body craves alignment. When we are properly aligned, our bones, not our muscles, support our weight, reducing effort and strain. The big payoff with proper posture is that we feel healthier, have more energy, and move gracefully. So while the word "posture" may conjure up images of book-balancing charm-school girls, it is not just about standing up straight. It's about being aware of and connected to every part of your self.
Posture ranks right up at the top of the list when you are talking about good health. It is as important as eating right, exercising, getting proper rest and avoiding potentially harmful substances like alcohol, drugs, and tobacco. Good posture is a way of doing things with more energy, less stress and fatigue. Without good posture, you cannot really be physically fit. Without good posture, you can actually damage your spine every time you exercise.
Ideally, our bones stack up one upon the other: the head rests directly on top of the spine, which sits directly over the pelvis, which sits directly over the knees and ankles. But if you spend hours every day sitting in a chair, if you hunch forward or balance your weight primarily on one leg, the muscles of your neck and back have to carry the weight of the body rather than it being supported by the spine. The resulting tension and joint pressure can affect you not only physically, but emotionally, too, -- from the predictable shoulder and back pain to headaches, short attention span, and depression.
Poor posture distorts the alignment of bones, chronically tenses muscles, and contributes to stressful conditions such as loss of vital lung capacity, increased fatigue, reduced blood and oxygen to the brain, limited range of motion, stiffness of joints, pain syndromes, reduced mental alertness, and decreased productivity at work. According to the Nobel Laureate Dr. Roger Sperry, "the more mechanically distorted a person is, the less energy is available for thinking, metabolism, and healing."
The most immediate problem with poor posture is that it creates a lot of chronic muscle tension as the weight of the head and upper body must be supported by the muscles instead of the bones. This effect becomes more pronounced the further your posture deviates from your body's center of balance.
To illustrate this idea further, think about carrying a briefcase. If you had to carry a briefcase with your arms outstretched in front of you, it would not take long before the muscles of your shoulders would be completely exhausted. This is because carrying the briefcase far away from your center of balance places undue stress on your shoulder muscles. If you held the same briefcase down at your side, your muscles would not fatigue as quickly, because the briefcase is closer to your center of balance and therefore the weight is supported by the bones of the skeleton, rather than the muscles.
In some parts of the world, women can carry big pots full of water from distant water sources back to their homes. They are able to carry these heavy pots a long distance without significant effort because they balance them on the top of their heads, thereby carrying them at their center of balance and allowing the strength of their skeleton to bear the weight, rather than their muscles.
Correcting bad posture and the physical problems that result can be accomplished in two ways. The first is by eliminating as much "bad" stress from your body as possible. Bad stress includes all the factors, habits, or stressors that cause your body to deviate from your structural center. Bad stress can result from a poorly adjusted workstation at work, from not having your seat adjusted correctly in your car, or even from carrying too much weight around in a heavy purse or backpack.
The second is by applying "good" stress on the body in an effort to move your posture back toward your center of balance. This is accomplished through a series of exercises, stretches, adjustments, and changes to your physical environment, all designed to help correct your posture. Getting your body back to its center of balance by improving your posture is critically important to improving how you feel.
Many patients with severe low back pain report that their pain came on suddenly when they did something as simple as bend down to pet their cat, put on their socks, or pick up the newspaper. Just about everyone would agree that a person's body should be able to handle such simple movements. So what has happened?
In every one of these cases, the joints of the patient's body were "all locked up" -- they were barely moving at all. When the joints in one area of the body do not move the way they should, other areas of the body are forced to move more in order to compensate. This creates a significant stress on those areas that have to pick up the slack, and it soon leads to pain and inflammation. At the same time, the areas that don't have normal movement will slowly worsen as the muscles continue to tighten, the joints stick together, and the ligaments and tendons shorten. This leaves the body in a very unstable condition; if left unchecked, this process will continue until the body can hardly move at all. That is how a person comes to suffer flare-ups of pain at the slightest provocation.
Most of us have seen people who have lost most of their normal mobility: they look like bodies have been starched stiff whenever they try to move around. This is especially prevalent among the elderly. Contrary to popular belief, however, this is not an inevitable effect of aging; rather it is the inevitable effect of not maintaining the body's mobility through exercise, healthy alignment, and body mechanics. There are people in their 60s, 70s, or even older, who are stronger and more flexible than the average person in their 30s, simply because they keep themselves exercising.
Maintaining mobility is critical in order to live free from pain and disability. Maintaining good mobility is not difficult, but it does not happen on its own. Just as in developing a good posture, it is necessary that you perform specific exercises and stretches to keep your muscles, ligaments, and tendons flexible and healthy. In addition, it is necessary that all of the joints in your body are kept moving correctly as well. Although this can be achieved to a great degree through stretching, most people also find routine chiropractic adjustments to be very beneficial.
Muscles are very efficient at getting stronger or weaker in response to the demands placed on them. Since most of us sit at a desk, drive a car, and sit on the sofa at home, many of our muscles are not challenged. Consequently, they become weak. At the same time, the muscles that are constantly used throughout the day become strong. This imbalance of muscle strength contributes to poor posture and chronic muscle tension. Left unchecked, muscle imbalances tend to get worse, not better, because of a phenomenon called "reciprocal inhibition."
Reciprocal inhibition literally means "shutting down the opposite." For all of the muscles that move your body in one direction, there are opposing muscles that move the body in the opposite direction. In order to keep these muscles from working against each other, when the body contracts one muscle group, it forces the opposing group to relax -- it shuts down the opposite muscles. When consistently only one set of muscles is used, the opposing group, from being continuously shut-down, is liable to atrophy.
This phenomenon is especially important to people who work at a desk, because all day long the same muscles in the upper back and chest area of the body are used. This means that all day long the body is essentially shutting down the opposite muscles in the middle back. Over time, the muscles in the middle back become very weak because they are not being worked like the muscles in the front. This contributes to poor posture and chronic muscle spasms and pain. The easiest way to correct this imbalance is to do specific exercises which will increase the strength of the back muscles, along with manual therapy and chiropractic care. Once the muscles in your middle back are strong, the tightness and poor posture simply disappear.
