I have trouble sleeping an unbroken night's sleep - and I've alway thought that it was something wrong, until I read about about how people used to sleep in times past, at Gail Hapke's Scribal Terror blog.
... A. Roger Ekirch, author of At Day's Close, [wrote] on an interesting and little known detail of sleep in times past:
For many centuries, and perhaps back to Homer, Western society slept in two shifts. People went to sleep, got up in the middle of the night for an hour or so, and then went to sleep again. Thus night — divided into a “first sleep” and “second sleep” — also included a curious intermission. “There was an extraordinary level of activity,” Ekirch told me. People got up and tended to their animals or did housekeeping. Others had sex or just lay in bed thinking, smoking a pipe, or gossiping with bedfellows. Benjamin Franklin took “cold-air baths,” reading naked in a chair.
