Vitality Supreme

The quality of the air is another important factor, though I need not dwell upon that here. The air you breathe during sleep should be especially fresh and pure, particularly so because of the more shallow character of the breathing. If you are in a room, all the windows should be open as wide as possible. If you have a covered balcony or porch, or if you can avail yourself of a flat roof, it is always advisable to sleep out-of-doors. The increased vitality will more than repay you for your trouble. There is something about out-of-door sleeping that vitalizes, energizes, and refreshes one to an unusual extent. Circulation is another important factor in sound sleep, especially for nervous persons. Many of those who complain of an inability to sleep suffer more or less from congestion of blood in the brain; also they complain of cold feet or cold hands and feet. In such instances, warm feet will often bring a solution of the problem. In some instances drinking a half cup of hot milk or hot water before going to bed will draw the blood from the brain and enable one to sleep. A hot foot bath before going to bed will do the same thing, or one may use a hot-water bag or hot flatiron wrapped up in flannels, or even a hot brick treated in the same way, to keep the feet warm when in bed. In extreme cases it might be advisable to apply cold packs to the head while applying heat to the feet or when taking the hot foot bath.
