  Its Necessity.—Rest is as necessary as exercise. We cannot be active continually. Repose must succeed labor. Alfred the Great is credited with the recommendation that each day be divided into three parts, eight hours for labor, eight hours for recreation, and eight hours for sleep. Change of Employment.—A change of occupation affords rest. The wood chopper finds relief from his ax by using his saw. A different set of muscles is brought into play. Persons might often save themselves from excessive fatigue by the adoption of this principle. When physical labor is made to alternate with mental activity, the sense of rest is more apparent. Sleep.—The best form of rest is found in sleep. All voluntary activity then ceases. Even the involuntary processes of circulation and respiration seem to share in the general restfulness, for during sleep their action is more tardy, and, as a result, the temperature of the body is somewhat lower. While the body is in action, the process of pulling down predominates, but during sleep nutrition goes on, the wasted tissues are built up, and we rise refreshed and prepared for the new day’s duties. Amount of Sleep.—All persons do not require the same amount of sleep. It is said that Frederick the Great slept only five hours each night. Napoleon Bonaparte could pass days with only a few hours’ rest. Persons whose labors are mental require more sleep than those who work with their hands. The average person in good health requires eight hours’ sleep. Children, invalids, and the aged need more. Those who take less should make a careful study of themselves to ascertain whether they get all the refreshment of mind and body that they need. If sleep is insufficient, it will show itself sooner or later in general lassitude and weakness. The imperative demands of Nature are shown in the recorded instances of sailors on war vessels falling asleep on the gun-deck while their ships were in action, of soldiers falling asleep on the march, and Position While Sleeping.—An active, healthy child will sleep well in almost any position, but a nervous, wakeful person, who is obliged night after night to woo sleep, must study what conditions are most conducive to its attainment. Most persons sleep best on the right side. In this position the stomach is easily emptied, and the liver does not press upon the heart and stomach. Those affected with heart trouble will experience less oppression and distress in this position than by sleeping on either the back or on the left side. The Pillow.—A high pillow, especially if firm and unyielding, cramps the neck and interferes with respiration and circulation. Some writers upon health advocate the use of no pillow, but most persons, either from habit or for more substantial reasons, find a pillow of moderate size to be of advantage. The Mattress.—The old-time bed-ticking filled with clean oats straw, thoroughly shaken up each day, and renewed once or twice a year, made a thoroughly comfortable and wholesome bed. In these modern days, hair, cotton, felt, and corn husk are Rest During the Day.—Almost everyone has experienced the invigorating influence of an after-dinner nap during the long days of summer. Many persons would accomplish more work by taking a rest of ten or fifteen minutes once or twice a day at all seasons of the year. To women in poor health, and to those who are overworked, this suggestion has special application. It not only rests the tired muscles but it soothes the nerves, and serves as a most refreshing tonic. Instead of being a loss of time, it will prove to be time saved. More actual work, both of hands and brain, will be accomplished, and with less expenditure of vital force. Dr. William Pepper accomplished an immense amount of work with but very little sleep. It was not unusual for him, when sorely in need of rest, to break off in the midst of his work, lie down and immediately go to sleep, and after five or ten minutes wake up refreshed. |
