Then there is the matter of deep breathing, which seems especially adapted to feeble or run-down physiques. That is a large subject more familiar to the people of the Orient than to us. Some Orientals are able to put themselves into trance-like sleep by their knowledge of deep breathing. Numerous books have been written treating of this subject, among the best of which are “The Science of Breath,” by Ramacharaka, and “The Law of Rhythmical Breath,” by Ella A. Fletcher, though the “Rhythmical Breath” seems fanciful to Western readers. Sleeplessness is sometimes due to lack of physical exercise, and, when that is so, no device is so effective as work—real physical effort. A great many persons take calisthenic exercises and go in for physical culture to develop muscles and also to regulate circulation so that sleep will come more readily. These are good makeshifts for persons who have no opportunity to work, but, where circumstances make actual labor possible, no substitute can satisfactorily take its place. Gardening, shoveling snow, sawing or chopping wood, all give a variety of motion and a zest of exertion superior to any gymnastics. Even a small amount of some such labor daily will often work a complete cure for insomnia. Everybody knows of some plan or device for inducing sleep, and all of them are more or less successful—sometimes. Indeed, this is so true that it leads to the belief that, after all, the expectation of sleep helps to bring it, and here suggestion and auto-suggestion come in. Of late, a number of persons have tried the starvation cure—fasting for several days. This is frequently successful with robust, hearty people, who may unconsciously be eating too much or eating too stimulating food. Many who feel unequal to a complete fast might cut down the amount of food as much as one-half, with happy results. A vegetarian diet undoubtedly helps, too, although among the lower animals carnivora sleep more than herbivora. The success of vegetarianism, both in insomnia and other diseases, may well be due to the diminished temptation to overeat and the less concentrated diet. In any event, it is well for the sufferer from sleeplessness to study his own case and experiment with any or all the known devices to see whether, by this means or that, he can lure sleep to his pillow again. And, speaking of pillows, it is well to remember that one pillow is better than two, and that the one should not be too high, too hard, too soft, or too warm, and that it should be thoroughly aired every day. It should be odorless and cool and have the cover changed frequently. Clean bed linen is in itself an effective device for inducing sleep, just as perfect ventilation adds an hundredfold to the refreshment we get from our slumbers. The best way to learn to sleep is to practice putting others to sleep. Thy gifts will be unto thyself when thy benefits are to another.
