The ancient Japanese art form of growing Bonsai trees is fascinating. Bonsai trees are essentially normal shrubs that have been consistently stressed in a particular way for a long time to create a posture which would never be found in nature. Depending on how the tree is stressed while it grows, it may end up looking like a miniature version of a full-sized tree, or it may end up looking like a wild tangle of branches with twists and loops. To most people, “good posture” simply means sitting and standing up straight. Few of us realize the importance of posture to our health and performance.
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 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.
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.
