In regard to the effects of protracting the time spent in repose, many
extensive and satisfactory investigations have been made. It has been
shown, that, during sleep, the body perspires most freely, while yet
neither food nor exercise are ministering to its wants. Of course, if we
continue our slumbers, beyond the time required to restore the body to
its usual vigor, there is an unperceived undermining of the
constitution, by this protracted and debilitating exhalation. This
process, in a course of years, renders the body delicate, and less able
to withstand disease; and in the result shortens life. Sir John
Sinclair, who has written a large work on the Causes of Longevity,
states, as one result of his extensive investigations, that he has never
yet heard or read of a single case of great longevity, where the
individual was not an early riser. He says, that he has found cases, in
which the individual has violated some one of all the other laws of
health, and yet lived to great age; but never a single instance, in
which any constitution has withstood that undermining, consequent on
protracting the hours of repose beyond the demands of the system.

Another reason for early rising, is, that it is indispensable to a
systematic and well-regulated family. At whatever hour the parents
retire, children and domestics, wearied by play or labor, must retire
early. Children usually awake with the dawn of light, and commence their
play, while domestics usually prefer the freshness of morning for their
labors. If, then, the parents rise at a late hour, they either induce a
habit of protracting sleep in their children and domestics, or else the
family is up, and at their pursuits, while their supervisors are in
bed. Any woman, who asserts that her children and domestics, in the
first hours of day, when their spirits are freshest, will be as well
regulated without her presence, as with it, confesses that, which surely
is little for her credit. It is believed, that any candid woman,
whatever may be her excuse for late rising, will concede, that, if she
could rise early, it would be for the advantage of her family. A late
breakfast puts back the work, through the whole day, for every member of
a family; and, if the parents thus occasion the loss of an hour or two,
to each individual, who, but for their delay in the morning, would be
usefully employed, they, alone, are responsible for all this wa
