“It is not the man or woman who lives regularly, eats temperately, and exercises the brain moderately, or even severely, if the habits are correct, and sufficient out-door air and exercise are had to oxygenize the blood and keep up muscular tone; it is not the muscle-worker, the agriculturist, the mechanic, the machinist; it is not the maid of all work, as a general thing. It is the brain-worker--the lawyer, merchant, doctor, banker, minister, teacher; it is the man who sits in his office or works in his store or shop in poor air and light, having little or no muscular exercise, who constantly thinks, is anxious, worried, careworn, a victim of the intense competition and excitement which modern business life imposes; it is the wife and mother who lives in the house all day, who is continually worried by household cares and anxieties, who is _socially_ taxed and excited; it is she who idles away her time, passing it in in-door indolence, who dresses unphysiologically, eats badly, feeds upon sensational literature, and lives under the reign of her emotional and passional nature; it is the poor factory girl or seamstress, plodding away through weary days, in stifling air and on starvation diet, as of baker’s bread and tea, debarred from all out-door recreation; or the school teacher who barely earns her living, though she works brain and nerves, almost daily, to the point of exhaustion. In these classes, subject to unphysiological habits of work, want of recreation, unfavorable surroundings, irregularity in eating, sleeping, etc.--more from lack of knowledge than from necessity--are found the victims.” IMPROPER FOOD, prominent in the causes of constipation, poisons rather than nourishes the body, inducing congestion of the alimentary canal by the irritation set up. Highly seasoned food and stimulating drinks excite extra secretions when first taken, but the reaction or secondary effect of the overstrain is torpor, and consequently absence of secretion. Notably, too, we have the same effect from aperient drugs. Even the too free and constant use of salt causes a dryness of the intestinal canal, probably from the fact of its stimulating power. Nature daily attests this statement by the demand for drink after partaking of salted meats, fish, etc. Food lacking in elements of nerve nutrition proves constipating; foods that are too concentrated are usually those that are highly carbonaceous, notably _fats_ and _sweets_, as well as those abounding in starch. In these the insufficient residue fails to furnish the needed volume to fecal matter. The absence of water, too, furnished by vegetables and fruits, causes a dryness of the contents of the intestinal canal, which of itself is an impediment to their onward passage through the bowels.
