A great book on this is E. Roger Ekirch’s <i>At Day’s Close</i>, which gives the whole history of this. Lots of people wake after 4 hours, then sleep again for several more. In early New England, people used to get up after their first sleep and greet others in the street, before going back to bed for their second sleep. It wasn’t unusual for people to ask in the morning, “how was your first sleep”?<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>Gretchen Gerzina<o:p></o:p></span></p></div></body></html>
