Too little heat is often as dangerous as too much; for you will insist on keeping warm, no matter what it may cost you in the future, and a cold room usually means hermetically sealed windows.

Remember that coal is cheaper than colds, to say nothing of consumption and pneumonia.

The same principles that apply to ventilating a living-room or day-room apply to ventilating a bedroom.

Here you can almost disregard drafts, except in the very coldest weather, and, by putting on plenty of covering, sleep three hundred days out of the year with your windows wide open and your room within ten degrees of the temperature outdoors.

You need not be afraid of catching cold.
