On the contrary, by sleeping in a room like this you will escape three out of four colds that you usually catch.

Sleeping with the windows wide open is the method we now use to cure consumption, and it is equally good to prevent it.
No bedroom window ought to be closed at the top, except when necessary to keep rain or snow from driving in.

Close the windows for a short time before going to bed, and again before rising in the morning, to warm up the room to undress and dress in; or have a small inside dressing-room, with your bed out on a screened balcony or porch.

But sleep at least three hundred nights of the year with the free air of heaven blowing across your face.

You will soon feel that you cannot sleep without it.
In winter, have a light-weight warm comforter and enough warm, but light, blankets on your bed, and leave the heat on in the room, if necessary--but _open the windows_.
