Those who are troubled with the no-sleep obsession will soon realize that they sleep as well as others if they cease thinking and talking so much about the subject. I have seen people suffering from this bad habit recover in one week. Those who have been taking drugs to induce sleep generally have a few bad nights when they give them up, after which the nervous storm subsides and sleep becomes normal. All drugs should be discarded. The physician who understands more about the working of nature than about the giving of drugs will have the best success in these cases. Soothing sleep always comes to people possessed of a controlled mind in a healthy body.
If the day has been exhausting and the nerves are so alive and wrought up that sleep will not come, do not allow the mind to delve into worry about it. Do not say to yourself: "I wish I could sleep. Why can't I sleep?" Such fretful thinking produces mental tension, which drives sleep away. Instead, say to yourself: "I am very comfortable. I am having a refreshing rest. It does not matter whether I sleep or not." By all means relax the body. Choose a comfortable position and remain quiet, having the muscles relaxed. It is remarkable how soon a relaxed body brings tranquility to a disturbed mind. Let a man in pugnacious mood relax his face and his fists and in a very short time his anger vanishes. It makes no difference whether a person sleeps eight hours on a certain night. If he is fairly regular about going to bed he will get enough sleep. Those who realize this truth do not complain of insomnia.
Most people who think much have an occasional night when an idea takes such strong possession of the brain and demands so forcibly to be put into proper shape, that they can not sleep. Under such circumstances it is as well to to get up and work out the idea. Three or four nights like that in the course of a year will do no harm.
People rarely sleep well when lying on the back. If the theory of evolution is correct, we were not intended to lie on our backs during sleep. A good position is to lie on the right side, the right leg being anterior to the left, both being flexed. Another position that is restful to many is to lie on the abdomen, the arms extended away from the body.
The breathing should be entirely nasal. It will not be nasal if there is obstruction in the nose. A healthy person who breathes through his mouth at night must use autosuggestion to overcome the habit. He should suggest to himself, "I will breathe through the nose; I will keep my lips together." If he persists in this, closes the mouth when he goes to sleep, in time the mouth-breathing will cease, and with it the disagreeable habit of snoring. The harmfulness of mouth-breathing is explained in another chapter.
At all times the bedroom should be well ventilated. Some people are in the habit of sleeping in unventilated bedrooms, but upon rising in the morning they throw the windows open and give the room a good airing. The ventilation does not do much good except when there is someone in the room. During the day the bedroom could be closed with very little harm ensuing, though it is best to have it sunned and aired as much as possible.
The sleeping porch is excellent. Outdoor sleeping is all right and it is not a modern fad. Where Benjamin Franklin got his information I do not know, but he has this to say about outdoor sleeping: "It is recorded that Methusaleh, who, being the longest liver, may be supposed to have best preserved his health, that he slept always in the open air; for when he had lived five hundred years an angel said to him: 'Arise, Methusaleh, and build thee an house, for thou shalt live five hundred years longer.' But Methusaleh answered, and said: 'If I am to live but five hundred years longer, it is not worth while to build me an house; I will sleep in the air as I have been used to do.'" This may partly account for some of his many years. His alleged conversation with the angel indicates that he was a man of equanimity.
Under ordinary circumstances those who sleep indoors should have one sash of window fully open for each person in the chamber, or more. It is well to have plenty of fresh air, but it is not best to sleep in a draught. When the wind is blowing through the windows it is not necessary to have them wide open, for an aperture of four inches will then give as much fresh air as a sash opening in calmer weather.
It is best to get up promptly upon awakening in the morning. Remaining in bed half asleep is productive of slothfulness. Too much sleeping and dozing make one dull.
Those who overeat require more sleep than moderate people. The sluggishness and sleepiness following a too heavy meal are familiar to all. Animals that do not get food regularly, but are dependent on the vicissitudes of preying for their nourishment, often gorge themselves so that they can not stay awake, but fall into a stupor, which may last for days. Man, who is generally assured of three meals a day, has no excuse for this form of self-abuse, but unfortunately he practices it too often. It is a gross habit, one in which people of refinement will not continue to indulge.
