A Lecture on the Preservation of Health Part 2

Be therefore temperate in eating, and eat only of such foods as are the plainest; and let a proper quant.i.ty of vegetable food be mixed with animal. If you value the preservation of health, never satiate yourselves with eating; but let it be a rule from which you ought never to depart, always to rise from table with some remains of appet.i.te: for, when the stomach is loaded with more food than it can easily digest, a crude and una.s.similated chyle is taken into the blood, pregnant with diseases. Nor is the quant.i.ty the only object of attention; the quality of the food is to be carefully studied; made dishes, enriched with hot sauces, stimulate infinitely more than plain food, and therefore exhaust the excitability, bringing on diseases of indirect debility; such as the worst kind of gout, apoplexy, and paralytic complaints. "For my part," says an elegant writer, "when I behold a fas.h.i.+onable table set out in all its magnificence, I fancy that I see gouts and dropsies, fevers and lethargies, with other innumerable distempers, lying in ambuscade among the dishes." Let it be therefore laid down as a rule by those who wish to preserve their health, and I have nothing to say to those who are indifferent on that head, to make their chief repast on one plain dish, and trifle with the rest.

It is by no means uncommon for a medical man to have patients, chiefly among people of fas.h.i.+on and fortune, who complain of being hot and restless all night, and having a foul taste in the mouth every morning: on examination it is found, that in nineteen cases out of twenty, it has arisen from their having overloaded their stomachs, and at the same time neglected to take proper exercise; for it must always be observed, that more may be eaten with safety, nay, more is even necessary, when a person takes a good deal of exercise.

When people take little exercise, and overload their stomachs, there lies within them a fermenting ma.s.s of undigested aliment; and it is not surprizing that this should irritate and heat the body during the night. This is likewise the foundation of stomach complaints, flatulencies, and all other symptoms of indigestion; which more frequently proceed from intemperance in eating and drinking than any other cause. The benefits arising from temperance are set in a striking light in the following allegory, which may be found in the Adventurer.

Esculapius, after his deification or admittance among the G.o.ds, having revisited his native country, and being one day (as curiosity led him a rambling,) in danger of being benighted, made the best of his way to a house he saw at some distance, where he was hospitably received by the master of it. Cremes, for that was the master's name, though but a young man, was infirm and sickly. Of several dishes served up to supper, Cremes observed that his guest ate but of one, and that the most simple; nor could all his intreaties prevail upon him to do otherwise. He was, notwithstanding, highly delighted with Esculapius's conversation, in which he observed a cheerfulness and knowledge superior to any thing he had hitherto met with.

The next morning, Esculapius took his leave, but not till he had engaged his good-natured host to pay him a visit at a small villa, a few miles from thence. Cremes came accordingly, and was most kindly received; but how great was his amazement when supper was served up, to see nothing but milk, honey, and a few roots, dressed in the plainest, but neatest manner, to which hunger, cheerfulness, and good sense, were the only sauces. Esculapius seemed to eat with pleasure, while Cremes scarcely tasted of them. On which a repast was ordered more suitable to the taste of our guest. Immediately there succeeded a banquet composed of the most artful dishes that luxury could invent, with great plenty and variety of the richest and most intoxicating wines. These too were accompanied by damsels of the most bewitching beauty. Cremes now gave a loose to his appet.i.tes, and every thing he tasted raised ecstasies beyond what he had ever known. During the repast, the damsels sung and danced to entertain them; their charms enchanted the enraptured guest, already flushed with what he had drank; his senses were lost in ecstatic confusion. Every thing around him seemed Elysium, and he was on the point of indulging the most boundless freedoms, when on a sudden their beauty, which was but a vizard, fell off, and discovered forms the most hideous and forbidding imaginable. l.u.s.t, revenge, folly, murder, meagre poverty, and despair, now appeared in the most odious shapes, and the place instantly became a most dire scene of misery and confusion. How often did Cremes wish himself far distant from such a diabolical company, and now dreaded the fatal consequence which threatened him. His blood ran chill at his heart, and joy and rapture were perverted to amazement and horror!--When Esculapius perceived it had made a sufficient impression on his guest, he thus addressed him: "Know, Cremes, it is Esculapius who has thus entertained you, and what you have beheld is a true image of the deceitfulness and misery inseparable from luxury and intemperance.

Would you be happy, be temperate: temperance is the parent of health, virtue, wisdom, plenty, and every thing that can make you happy in this or the world to come. It is indeed the true luxury of life, for without it life cannot be enjoyed." This said, he disappeared, and left Cremes (instead of an elegant apartment) in an open plain, full of ideas quite different from those he had brought with him.

On his return home, from the most luxurious, he became one of the most temperate men, by which wise method he soon regained health.

Frugality produced riches, and from an infirm and crazy const.i.tution, and almost ruined estate, by virtue of this infallible elixir, he became one of the happiest men breathing, and lived to a healthy old age, revered as an oracle for his wisdom throughout all Greece.

If temperance be necessary with regard to food, it is still more so with respect to strong liquors; these diffusible stimuli, by quickly exhausting the excitability, soon blast the vigour, and sap the foundation of the strongest const.i.tution. Their immediate effects you know are stimulant; they raise the animal spirits, produce a cheerful state of mind, and if taken in greater quant.i.ty, cause intoxication, or that temporary derangement of the thinking powers which arises from too great a degree of excitement: but let us see what happens the next day; the animal spirits are exhausted, and the person thus situated, finds himself languid and enervated to a great degree; for it seems a law of the human body, that the spirits are never artificially raised, without being afterwards proportionably depressed; and to shew clearly that in this state the excitability is exhausted, the ordinary powers which in general support life, will not have their due effect; and a person thus situated finds most relief the next day, from taking some of the same stimulus which occasioned the exhaustion; because the common exciting powers can scarcely act upon his exhausted excitability.

But though the excitability be in this way exhausted, it will in the course of a day or two be again acc.u.mulated, and it may, perhaps, be suspected that this exhaustion can do no harm to the const.i.tution; but this is a premature conclusion, and quite contrary to fact and experience, as well as to reason; for, just in the same manner that a pendulum, made to vibrate in the arc of a circle, will never return exactly to the same height, but fall a little short of it every time; so, though the excitability may be again acc.u.mulated, it never can be brought back to what it was before; and every fresh debauch will shorten life, probably two or three weeks at least, besides debilitating the body, and bringing on a variety of diseases, with premature old age.

Those who drink only a moderate quant.i.ty of wine, so as to make them cheerful, as they call it, but not absolutely to intoxicate, may imagine that it will do them no harm. The strong and robust may enjoy the pleasures of the bottle and table with seeming impunity, and sometimes for many years may not find any bad effects from them; but depend upon it, if a full diet of animal food be every day indulged in, with only a moderate portion of wine, its baneful influence will blast the vigour of the strongest const.i.tution.

While we are eating, water is the best beverage. The custom of drinking fermented liquors, and particularly wine, during dinner, is a very pernicious one. The idea that it a.s.sists digestion, is false; those who are acquainted with chemistry know, that food is hardened, and rendered less digestible by these means, and the stimulus which wine gives to the stomach is not necessary, excepting to those who have exhausted the excitability of that organ by the excessive use of strong liquors. In these. The stomach can scarcely be excited to any action without the a.s.sistance of such a stimulus. If food wants diluting, water is the best diluent, and will prevent the rising, as it is called, of strong food, much better than wine or spirits.

Before I finish this subject, I shall say a few words on the pernicious custom of suffering children to drink wine, or other fermented liquors. Nothing is more common than to see, even very young children come to the table after dinner, to drink a gla.s.s of wine. The least quant.i.ty produces violent effects on their acc.u.mulated excitability, and by quickly exhausting it, ruins their const.i.tutions through life, and often renders them habitual drinkers.

I can scarcely help attributing in some degree the many stomach complaints we meet with, among young people in the present age, and which were unknown to our forefathers, to the abominable practice of suffering children to drink fermented, or spirituous liquors. You must all have observed how soon children are intoxicated and inflamed by spirituous liquors; you may judge then, that if these liquors be only a slow poison to us, they are a very quick one to them. A gla.s.s of wine, on account of the acc.u.mulated excitability of children, will have more effect upon them, than a bottle will have upon an adult accustomed to drink wine. If therefore, the health of a child, and its happiness through life be an object, never suffer it to taste fermented, or spirituous liquors, till it be fifteen or sixteen years of age, unless a little wine be necessary as a medicine.

It now only remains for me to take some notice of exercise. Of all the various methods of preserving health, and of preventing diseases, which nature has suggested, there is none more efficacious than exercise; it puts the fluids all in motion, strengthens the solids, promotes perspiration, and occasions the decomposition of a larger quant.i.ty of atmospheric air in the lungs. Hence, in order to preserve the health of the body, the author of nature has made exercise absolutely necessary to the greater part of mankind for obtaining the means of existence.--Had not exercise been absolutely necessary for our well-being, says the elegant Addison, nature would not have made the body so proper for it, by giving such an activity to the limbs, and such a pliancy to every part, as necessarily produce those compressions, extensions, contortions, dilatations, and all other kinds of motions, that are necessary for the preservation of such a system of tubes and glands.--And that we might not want inducement to engage us in such exercise of the body as is proper for its welfare, it is so ordered, that nothing valuable can be procured without it. Not to mention riches and honors, even food and raiment are not to be come at without the toil of the hands and sweat of the brow. Providence furnishes materials, but expects that we should work them up ourselves. The earth must be laboured before it gives its increase, and when it is forced into its several products, how many hands must they pa.s.s through before they are fit for use? Manufactures, trade, and agriculture, naturally employ more than nineteen parts of the species out of twenty; and as for those who are not obliged to labour by the condition in which they are born, they are more miserable than the rest of mankind, unless they indulge themselves in that voluntary labour which goes by the name of exercise.

Of all the different kinds of exercise, there is none that conduces so much to health as riding; it is not attended with the fatigue of walking, and the free air is more enjoyed in this way than by any other mode of exercise. Where it cannot be used, walking, or exercise in a carriage, ought to be subst.i.tuted.

The best time for taking exercise is before dinner, for the body is then more vigorous and alert, and the mind more cheerful, and better disposed to enjoy the pleasure of a ride or walk. Exercise after a full meal disturbs digestion, and causes painful sensations in the stomach and bowels, with heart-burn, and acid eructations.

But whatever mode of exercise you use, it ought not at first to be too violent. Dr. Armstrong has given us an excellent rule--

'Begin with gentle toils, and as your nerves 'grow firm, to hardier, by just steps aspire.

'The prudent, even in every moderate walk, 'at first but saunter, and by slow degrees 'increase their pace.'

THE END.
