Sleep: How Much Rest the Body Requires
Sir Philip Sidney calls sleep, “the poor man's wealth,” and, he might have added, it is every man's health. Men have often, according to their notions, attempted to limit or extend the hours of sleep. Thus the “immortal Alfred” of England divided the day into three portions of eight hours each, assigning one for refreshment and the health of the body by sleep, diet, and exercise, another for business, and the third for study and devotion. Bishop Taylor considered three hours’, and Richard Baxter four hours’, sleep sufficient for any man. “Nature requires five,
Custom gives seven,
Laziness takes nine,
And wickedness eleven.”
The error into which these and others have fallen arises not only from the fact that in this, as well as in other things, every man is a law to himself, but from the varying amount required in each individual case at different times, depending upon the amount of renovation required by the nervous and muscular systems. John Wesley, the distinguished founder of Methodism, who attained the age of eighty-eight, and who could command sleep on horseback, says very properly, in some curious remarks which he has left upon sleep, that no measure will do for all, nor will the same amount of sleep suffice even for the same person at all times. A person debilitated by sickness requires more of “tired nature’s sweet restorer” than one in vigorous health. More sleep is also necessary when the strength and spirits are exhausted by hard labor or severe mental efforts.—Everybody’s Journal.
