One of the simplest and most effective methods of avoiding self-poisoning is by maintaining an erect posture. In an erect posture the abdominal muscles tend to remain taut and to afford proper support or pressure to the abdomen, including the great splanchnic circulation of large blood-vessels. In an habitual slouching posture, the blood of the abdomen tends to stagnate in the liver and the splanchnic circulation, causing a feeling of despondency and mental confusion, headache, coldness of the hands and feet, and chronic fatigue or neurasthenia, and often constipation.

A slouching attitude is often the result of disease or lack of vitality; but it is also a cause.

The “Consumptive Stoop”

There is some reason to believe that “the consumptive stoop” leads to tuberculosis partly through the lowering of resistance resulting from the poisoning produced by a chronically relaxed abdomen.

Many persons who have suffered for years from the above-named symptoms have been relieved of them after a few weeks of correct posture, sometimes reenforced by the artificial pressure of an abdominal supporter and by special exercises to strengthen the abdominal muscles.

Lying face downward with a pillow under the abdomen presses the blood out of the congested splanchnic circulation.

Breathing and Posture

Breathing exercises are also very useful for correcting the chronic evils of bad posture. Exercises taken when lying on the back, by raising the legs or head, strengthen the abdominal muscles. Slow, deep breathing, through the nose, while lying on the back, with a weight on the abdomen, such as a bag of sand—2 to 4 lbs.—is beneficial.

Standing and Walking

In walking, the most common error is to slump, with the shoulders rounded, the stomach thrust out, the head thrust forward, chin up, and the arms hanging in front of the body. To those who walk or stand in this fashion, let it be known that this is the “habitus enteroptoticus,” or asthenic droop. It is characteristic of those with weak muscular and nervous systems.

To set the shoulders back and square them evenly, to keep the chest high and well arched forward, the stomach in and the neck perpendicular, like a column, and the chin in, are simple fundamental measures that most people know and many people disregard.

One should have a sense of the firmness or tautness of the abdominal muscles and not of flabby relaxation. When one changes a slouching posture into an erect posture, there is a sense of having reversed the way the body hangs, as it were, on the spinal column.

Whether sitting, standing, or walking, these principles, that involve a correct and pleasing carriage and a healthful relation of the organs and structures of the body, should be observed by both men and women.

This perfect physical poise which places the muscles, organs, circulation, and even the brain and nervous system in harmonious relationship, adjusted for the best achievement, is well expressed in sculpture dating back to 500–600 BC, when the Spartans attained supremacy in Greece. This same poise and symmetry is shown in modern sculpture of fine types of manhood and womanhood.

The Feet

It is not enough to have an erect carriage and a well-poised head. We must also have well-directed feet. It is pitiable to think how the work of a fine head may be spoiled by misdirected feet. Weak foot, and its final stage, flat foot, are more common among women than they are among men, because it is not a purely local condition in the arch of the foot, as so many suppose, but primarily due to a general weakened condition of the leg muscles that support the arch. The more vigorous exercise of boys as compared to that of girls protects them in some degree from this malady.

Toeing Straightforward

Weak feet are gradually converted into flat feet by faulty standing and walking posture and lack of leg exercise. Toeing out, whether walking or standing, so commonly noted among girls and women, places a great strain upon the arches of the foot. The correction of this fault by persistent toeing in, Indian fashion, and daily exercise of the leg muscles (rising on the toes twenty to forty times night and morning), will do much to prevent flat foot.

Chairs

Not only in standing, but in sitting, erect posture has been found to be a much more important factor in the maintenance of good health than is generally supposed. A rocker, or any other chair which tilts, is restful to the abdominal circulation, if the lower back is properly supported. Bad posture is common among sedentary people. The ordinary chair invites it. Every chair should be modeled like most modern automobile seats, on a curve to fit the back. Almost any chair can be corrected by placing a cushion so as to support the hollow of the back of the sitter. The responsibility for correct posture rests, however, on the individual and not on the chair.

Sitting

In sitting at a desk or table, when reading or working, the common fault is to adopt a sprawling attitude, with the shoulders hunched up, the elbows stretched outward, the body too far away from the desk or table, and the weight resting on the buttocks. Very often the desk or table is too high and the arms can not rest easily upon it, thus causing a continuous strain on the structures around the shoulder-joints.

To correct this fault, use if possible a chair with a back that curves forward. Sit well back in the chair, but close to the desk, so that the fleshy inner part of the forearms may rest easily upon its surface without pushing up the shoulders.

When it is necessary to lean over a desk, acquire the habit of inclining the body forward by bending at the hips and not by distorting the chest.

The arms should hang easily from the shoulder and the elbows should not rest upon the table. The shoulders should be evenly square, as in the correct standing posture. In right-handed people, the light should fall over the left shoulder or directly from above. The body should rest upon the full length of the thighs, not solely on the buttocks, and the feet (not legs) be crossed and resting lightly on the ground on their outer edges. In other words, the position should be freed from strain, especially strain of special groups of muscles.

Pains, erroneously ascribed to rheumatism or sciatica, are often due to faulty posture. Writer’s cramp and many other needless miseries are caused by neglect to develop proper postural habits in working or reading.

Posture in Children

In children faulty posture may mar the future of the individual by causing spinal curvature and physical deformities that interfere with physical and mental efficiency throughout life, and often lower the resistance to disease. Deep breathing through the nose and “setting up” exercises are of incalculable importance in such cases.

The various types of faulty posture are so numerous that they can not be listed here. Having once grasped the meaning of correct posture, however, we can form a standard for ourselves, and any departure from this standard should be looked upon as a menace to health. As in the case of eye-strain, flat foot, work, worry, and drink, much depends on the original physical and mental endowment of the individual as to how much harm results from faulty posture. But always some harm results.

Teaching Correct Posture

The teaching of proper standing, proper walking and proper sitting should be a part of all school discipline as it is at military schools, especially as there is the temptation to crouch over the school-desk—which is usually the source of the first deviation from natural posture. An infant before it goes to school usually has a beautiful, erect carriage, with the head resting squarely on the shoulders.

Posture and Character

An erect posture is attractive from an esthetic point of view, and for that reason is sure again to become fashionable with women, after a due reaction from the present slouching vagary. It is also closely associated with self-respect. We know that any physical expression of an emotion tends reflexly to produce that emotion. Therefore, not only does self-respect naturally tend to brace a man’s shoulders and straighten his spine, but, conversely, the assumption of such a braced-up attitude tends to “brace up” the man’s mind also. Tramps and other persons who have lost their self-respect almost invariably slouch, while an erect carriage usually accompanies those feeling their respectability. We jokingly refer to those whose self-respect verges on conceit as “chesty,” while we compliment one who is not so extreme by saying, “He is no slouch.”

Between the slouch and slink of the derelict and the pompous strut of the pharisee, or the swagger of the bully or the dandy, there is the golden mean in posture, which stands for self-respect and self-confidence, combined with courtesy and consideration for others.
