WHAT HASTENS AND WHAT RETARDS PUBERTY?
ОглавлениеAs a rule, we find that those who develope early, fade early. A short childhood portends a premature old age. It often foreshadows, also, a feeble middle-life.
Having ascertained, therefore, what is the average age at which puberty takes place with us, let us see what conditions anticipate or retard this age.
The most important is climate.
In hot climates, man, like the vegetation, has a surprising rapidity of growth. Marriages are usual at twelve or fourteen years of age. Puberty comes to both sexes as early as at ten and eleven years. We even read in the life of Mohammed, that one of his wives, when but ten years of age, bore him a son. Let another dozen years pass, and these blooming maidens have been metamorphosed into wrinkled, faded old women. The beauty of their precocious youth has withered almost literally like a flower which is plucked.
Very different is it in the cold and barren regions of the far north. There man, once more partaking of the nature of his surroundings, yields as slowly to the impulses of his passions as does the ice-bound earth to the slanting rays of the summer sun. Maturity, so quick to come, so swift to leave in the torrid heats, arrives, chilled by the long winters, to the girls of Lapland, Norway, and Siberia, only when they are eighteen and nineteen years of age. But, in return for this, they retain their vigor and good looks to a green old age.
Between these extremes, including as they do the whole second decade of existence, this important change takes place normally in different latitudes. We have said that in the middle temperate zone the proper age is fourteen years and six months. Let us now see what conditions lead to deviations from this age in our climate.
First on the list is that sacred fire handed down to us from our ancestors, which we call, in our material language, the constitution.
The females of certain races, certain families, it is often noticed, mature earlier than their neighbours. Jewesses, for example, are always precocious, earlier by one or two years. So are colored girls, and those of creole lineage. We can guess the reasons here. No doubt these children still retain in their blood the tropic fire which, at comparatively recent periods, their forefathers felt under the vertical rays of the torrid zone.
Nor is this all. It is well ascertained, from numerous observations, that brunettes develope sooner than their blonde sisters; that those who will grow to be large women are slower than those whose stature will be small; that the dark-haired and black-eyed are more precocious in this respect than the light-haired and blue-eyed; that the fat, sluggish girl is more tardy than the slender, active one; that, in general, what is known as the nervo-bilious temperament is ever ahead of that called the lymphatic or phlegmatic.
It is a familiar fact, that it is not a good sign to see this change before the usual average time. It betokens a weakly, excitable, diminutive frame. Hard labor, vigorous, regular muscular exertion—prime health, in other words—never tends to anticipate this epoch, but rather to retard it.
With this warning fresh in our ears, let us now rehearse what causes constantly incline unduly to hasten puberty, and thus to forestall wise Nature in her plans for health and beauty. They are of two kinds—physical and mental.
Idleness of body, highly-seasoned food, stimulating beverages, such as beer, wine, liqueurs, and, in a less degree, coffee and tea, irregular habits of sleep—these are the physical causes of premature development. But the mental causes are still more potent.
Whatever stimulates the emotions leads to an unnaturally early sexual life. Late hours, children's parties, sensational novels, 'flashy' papers, love stories, the drama, the ball-room, talk of beaux, love, and marriage—that atmosphere of riper years which is so often and so injudiciously thrown around childhood—all hasten the event which transforms the girl into the woman. A particular emphasis has been laid by some physicians on the power of music to awaken the dormant susceptibilities to passion, and on this account its too general or earnest cultivation by children has been objected to. Educators would do well to bear this caution in mind.
How powerfully these causes work is evident when we compare the average age of puberty in large cities and in country districts. The females in the former mature from six to eight months sooner than those in the latter. This is unquestionably owing to their mode of life—physically indolent, mentally over-stimulated. The result, too, is seen with painful plainness in comparing the sturdy, well-preserved farm-wife of thirty, with the languid, pale, faded city lady of the same age.
