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. Young children should take a nap each day. They are so active that they need this rest. Adults can with profit take a short nap, not to exceed thirty minutes, after lunch. Those who are nervous owe it to themselves to take a nap. Those who use the brain a great deal will find the midday nap a great restorer. If sleep will not come, they should at least close their eyes and remain relaxed for a short time. A long nap makes one feel stupid.
