get up at once, open the bed, air the sheets, remove the night clothing and walk about the room for a few minutes, rubbing the body briskly with the bare hand at the same time. A tepid sponge bath, followed by a vigorous rubbing kept up until really tired, will conduce to sleep in many cases. Sometimes a change of bed, or pulling the bed to pieces and arranging it again, is just the thing needed to bring sleep.
