Segmented Sleep Patterns of our Ancestors

Sunday, September 1st, 2013

Did you know that the sleeping habits of our ancestors were different than our own today?  With the lack of electricity and street lamps, people had 2 nightly sleep cycles.  The first one lasted 3-4 hours. Then upon waking, people would get up and be active for 1-2 hours and then fall back to sleep until morning; a 12 hour cycle in all.

This phenomena was first rediscovered by Professor Roger Ekirch of Virginia Tech in 1990, after doing copious research of past literature, court documents, and personal papers.
