Definitions Monophasic Sleep: Sleep for one period of time per day Biphasic Sleep: Sleep for two periods of time per day Polyphasic Sleep: Nap When Needed 20-30 minutes when needed Biphasic / Siesta Cycle Sleep roughly 4 hours at night,
then take a long nap (about an hour
and a half) in the afternoon Uberman Cycle Take half hour naps every 4 hours
Total Sleep Time: 3 hours per day Everyman Cycle One long sleep with several naps 1.5 hours
20 min naps (4-5 x a day) 3 hours
20 min naps (3 x a day) Dymaxion Cycle Sleep for 30 minutes every 6 hours
Total Sleep Time: 3-4 Hours Per Day What We're Talking About • General Information About Sleep • Alternative Wake-Sleep Schedules • What does the research say? Sleep for multiple periods per day Uncommon Alternatives Additional Notes • Somewhat standard solutions to sleep deprivation

• Many people currently use these alternatives without much thought

• Incompatible with "9-5" work schedule

• Societal dislike for naps Additional Notes • Must maintain sleep schedule closely (much more rigid system)

• Total hours of sleep per day significantly lowered from 7.5-8 hours

• Many positive testimonials--but lack of scientific research on these cycles specifically The Myth of the 8 Hour Sleep
Stephanie Hegarty 1990's Thomas Wehr
• Biphasic Sleep (4 hours -- 1-2 hours -- 4 hours)

2001 Roger Ekirch (Historian)
• 500+ references to biphasic sleep
• Street Lighting Polyphasic & Ultrashort Sleep Schedules
Claudio Stampi • Mimics sleep patterns in nature
• Babies & Elderly are polyphasic
• Isolated cultures are polyphasic • Experiment 1: 2 out of 11 people did well
• Experiment 2: 6 Air Force Cadets
• Could work for 2-3 months
• Motivation a key factor   Adult Napping & It's Effects on
Ability to Function --David Dinges • Negative stigma associated with napping

• Naps are "neither consistently beneficial nor
detrimental" (Why We Nap, 129)
