Chapter IV (3)

Whether taken alone or with food, the tendency of alcohol throughout is to lessen the churning movements of the stomach, and leads to atony of that organ, which in turn leads to dilatation of the stomach.

Alcohol appears to have a particularly deleterious effect on the digestion of women. This is explained by the fact that men lead a more active outdoor life, and consequently retain their appetite for food longer than women. For the same reason, they are able to work off the effects of drinking more easily and start afresh the assimilation of food. The indoor life led by women, their clothing, worn tight around the stomach, are added causes for lack of appetite. Catarrh of the stomach results; this is followed by insufficient food and an increased amount of stimulants. There follow nausea, irregular and insufficient nutrition, indigestion, and a faulty elaboration of the food.

By its action on the liver alcohol interferes with the amount and quantity of bile, and so inevitably leads to indigestion and constipation, and a similar interference with the action of the liver-cells and their chemical changes set up in many cases gouty conditions, accompanied by mental depression and irritability.

Diseases of the liver occur more frequently as the result of taking frequent small doses of alcohol, though never reaching the stage of intoxication, than as the result of indulging more freely, but at longer intervals.

_The Effect of Alcohol on the Blood._—The blood is a mixture of corpuscles and a fluid known as the blood plasma. The corpuscles are of two kinds—red and white. The red blood-corpuscles are the oxygen carriers; they carry the oxygen to the tissues, where they readily give it up. They are constantly being destroyed by the liver and spleen, and are replaced by new ones, which come from the red marrow of bones. The white corpuscles are much fewer in number, but they play a most important part in protecting the body against disease. It is now about twenty years since Professor Metchnikoff, of the Pasteur Institute of Paris, announced to the world his discovery that the white corpuscles have the power of destroying the microbes to which so many diseases are due. These white blood-cells form the standing army or policemen of the body, and their duty is to attack, and, if possible, to destroy, any foreign matter, such as dust or disease germs.

The plasma of the blood contains various kinds of salts, and include sodium chlorid or common salt, the phosphates, and chlorids of calcium and potassium.

The way which the body fights disease is partly by means of the white blood-corpuscles, which totally destroy the germs, and partly by the increase in the blood of those chemical substances which are antidotes for the poisons given out by the germs.

Alcohol taken into the stomach is quickly absorbed and reaches the blood in two minutes. The maximum of alcohol is found in the blood in fifteen minutes after it is swallowed.

The blood is the medium by which food and oxygen are conveyed to the tissues, and by which the refuse material from the tissues is carried away; alcohol interferes with both these processes.

The red cells are liable to become damaged and anemia results. It has now been proved that even tiny doses of alcohol paralyze more or less the white cells, and thus interfere with their power of destroying microbes. Chemical substances tend to exert a delaying or inhibitory influence over the chemical processes of the body. These chemical processes are oxidation, the storing up of nutriment, the manufacture of secretion, the production of energy and muscular movement, and the excretion of waste materials.

The greatest possible difference exists as to the rate at which oxidation goes on. When there is nothing to hinder its occurrence, the poisonous toxins and waste matters are rapidly burned up and eliminated and health prevails. Alcohol, by its affinity for oxygen, robs the tissues of oxygen which they would otherwise use for combustion. Hence the tissues are kept starving for oxygen, metabolism is interfered with, and they cannot get rid of their waste material.

This delayed oxidation tends to increase the body weight. The cells in an intermediate stage of fatty degeneration clog the body, and, of course, add to its weight. The natural effect of taking alcohol is to make the body obese. On abstaining from alcohol, the superfluous tissue is often burned away, and the weight of the body reduced, and a look and feeling of youth is recovered.

_The Effect of Alcohol on the Heart and Circulation._—By the circulation we understand the driving of the fluid blood around the body, through the blood-vessels, such driving being maintained by the pumping power of the heart, which is practically a hollow muscle.

In consequence of this pumping power of the heart, the blood in the vessels is under considerable pressure, which is naturally increased if the blood-vessels are narrowed or contracted, and diminished if the blood-vessels are expanded or dilated.

Gradual deterioration in the heart power is a cause of premature death. One of the early indications that the foregoing changes may be occurring in a heart is a sense of fatigue and breathlessness on slight exertion, or a feeling of disinclination for normal effort. The result of such depression of the efficiency of the heart is often seen when the individual is attacked by some disease; she succumbs to heart failure, instead of being able to resist the disease. This probably accounts for a great many deaths between forty and sixty years of age.

Further, it must be remembered that all the nutritive action of the blood depends on its power of rapidly filtering through the walls of the blood-vessels to the tissues, and, conversely, its power of drawing off the waste-products of the tissues depends on the facility with which such products can penetrate its walls.

As soon as degeneracy sets in, the walls of all vessels tend to become thickened, and the active transference through them, more and more prevented; the nutrition of the body is thus gravely hampered, and, with the advance of this thickening of the walls, the vessels are less able to adjust themselves to the variations in pressure from within; and, finally, when unable to withstand the pressure, they rupture, causing hemorrhage and apoplexy, which, when occurring in the brain, cause paralysis and mental decay.

A similar degeneration takes place in old age, but the point is, that many persons, instead of waiting until old age comes to them, deliberately precipitate these senile changes.

_The Effect of Alcohol on the Kidneys._—The elaborate mechanism of the kidneys consist of a filtering system of thousands of tubules, arranged closely side by side, whose function it is to carry away from the body the waste material, which otherwise would interfere with the vitality of the different organs.

The part played by the kidneys in rapidly eliminating effete material cannot be too carefully safeguarded. Anything which interferes with its work will sooner or later cause a retention of waste-products in the system, and will also permit of the escape of valuable albuminous materials of the substance of the blood through the filtering apparatus. The effect of alcohol upon the kidneys can only be described as disastrous. In proportion as the kidney shrinks, there is a diminution of the excretion of urine, and, finally, the condition known as Bright’s disease is established.

_The Effect of Alcohol on the Muscular System._—The muscular tissue forms 43 per cent. of the body weight. It has been proved that under the moderate use of alcohol the muscles become flabby and less vigorous and effective; that troops cannot work or march on alcohol; that in training for athletics, for races, or for other sports, total abstinence is always practised; the true sportsman depends quite as much on his brain as on his muscles for success. In England it is recognized that total abstinence is a necessity where great exertions are concerned, and it is now beyond all question that alcohol, in even so-called dietetic quantities, diminishes the output of muscular work, both in quantity and quality, and that the best physical results are obtained under total abstinence from its use.

Alcohol actually lowers the temperature of the body from three-fourths of one degree to three degrees. This depression of temperature is not transient, but lasts for several days, so that its use, when the person is exposed to intense cold, is extremely hazardous to life.

_The Effects of Alcohol on the Nervous System._—Kraepelin has carried out a series of experiments to prove the effects of small doses of alcohol on the output of work. In all mental work there are two elements to be considered, namely, quality and speed. Now, all observers are agreed that the quality of mental work is affected even before speed, more mistakes being made. Tests were made in reading aloud; in adding figures in various combinations; in type-setting; and in memorizing; in all these instances it was found that, after taking moderate doses of alcohol for a number of consecutive days, the work done was less, was less accurate, and that there was a decrease in the power of memorizing.

Another series of investigations, made by Rudin to determine how long the intellectual abilities continue to be depressed after the effects of alcohol pass off, showed that the effects of a single dose of alcohol persisted until noon or evening of the next day.

Von Helmholtz, one of the greatest observers and thinkers of the nineteenth century, noted on himself the effect of alcohol in interfering with the highest powers of thought and conception. Describing the conditions under which his highest scientific thoughts had matured and come to fruition, he said: “As far as my experience is concerned, they never come to a wearied brain or at the writing-desk; they were especially inclined to appear to me while indulging in a quiet walk in the sunshine or over the forest-clad mountains, _but the smallest quantity of alcohol seemed to drive them away_.”

Professor Sikovsky’s testimony is that “alcohol diminishes the rapidity of thought, makes the imagination and the power of reflection commonplace and deprived of originality, acts upon fine and complex sensations by transforming them into coarse and elementary ones, provokes outbursts of evil passions and dispositions, and in this predisposes men to strife and crime, and upsets habits of work and perseverance.”

Self-control is one of the highest functions of the brain, and the racial power which results to a people as a consequence of the individual practice of self-control cannot be too highly estimated. Therefore, children are trained as far as possible to control their emotions and actions. Alcohol diminishes and breaks down this power of acquired self-control, undoing the work of parents and educationalists. Quite small doses are often responsible for reckless and self-pleasing actions, which are far reaching in their results in loss of moral tone and self-respect. The ideals of duty are lost sight of, and, at best, leave the individual in a laissez-faire attitude. Among the depressant effects of alcohol are intellectual lethargy and a sense of fatigue, which, combined with the other factors, lessen the capacity for genuine enjoyment and pleasure.
