348. Have you any remarks to make on the sleep of boys and girls?
Sleeping-rooms are, generally, the smallest in the house, whereas, for health’s sake, they ought to be the largest. If it be impossible to have a large bedroom, I should advise a parent to have a dozen or twenty holes (each about the size of a florin) bored with a center-bit in the upper part of the chamber-door, and the same number of holes in the lower part of the door, so as constantly to admit a free current of air from the passages. If this cannot readily be done, then let the bedroom door be left ajar all night, a door-chain being on the door to prevent intrusion; and, in the summer time, during the night, let the window-sash, to the extent of about two or three inches, be left open.
If there be a dressing-room next to the bedroom, it will be well to have the dressing-room window, instead of the bedroom window, open at night. The dressing-room door will regulate the quantity of air to be admitted into the bedroom, opening it either little or much, as the weather might be cold or otherwise.
Fresh air during sleep is indispensable to health.—If a bedroom be close, the sleep, instead of being calm and refreshing, is broken and disturbed; and the boy, when he awakes in the morning, feels more fatigued than when he retired to rest.
If sleep is to be refreshing, the air, then, must be pure, and free from carbonic acid gas, which is constantly being evolved from the lungs. If sleep is to be health-giving, the lungs ought to have their proper food, oxygen,—and not be cheated by giving them instead a poison, carbonic acid gas.
It would be well for each boy to have a separate room to himself, and each girl a separate room to herself. If two boys are obliged, from the smallness of the house, to sleep in one room, and if two girls, from the same cause, are compelled to occupy the same chamber, by all means let each one have a separate bed to himself and to herself, as it is so much more healthy and expedient for both boys and girls to sleep alone.
The roof of the bed should be left open—that is to say, the top of the bedstead ought not be covered with bed furniture, but should be open to the ceiling, in order to encourage a free ventilation of air. A bed-curtain may be allowed on the side of the bed where there are windy currents of air; otherwise bed-curtains and valances ought on no account to be allowed. They prevent a free circulation of the air. A youth should sleep on a horse-hair mattress. Such mattresses greatly improve the figure and strengthen the frame. During the daytime, provided it does not rain, the windows must be thrown wide open, and, directly after he has risen from bed, the clothes ought to be thrown entirely back, in order that they may become, before the bed be made, well ventilated and purified by the air:
“Do you wish to be healthy?—
Then keep the house sweet;
As soon as you’re up
