  9. 9. Sleep Trackers and Apps• Sleep Tracker Zeo Wakemate• Android – Sleep as Android – Sleepbot Tracker – Stopwatch & Timer +
  10. 10. Maximize Sleep BenefitsUnbroken sleep yield the best results!• Minimize Disturbances• Eliminate Before Bed• No Intake Within 30 Minutes of Bed• Ear Plugs and/or White Noise• Keep Pets Out• Keep the Room Dark
  11. 11. Sleep TipsIf you have a hard time sleeping, try these tips:• Create a consistent routine for yourself• Meditate – sitting or lying down• Check the temperature• Phones and TVs• Make your bed for sleeping and sex only• Sleep with intention
  12. 12. Sleep Myths• Sleep Debt and Weekend Sleep-Ins• 6 Hours is Plenty• Getting Lots of Sleep = Getting Good Sleep• Alcohol helps you sleep better• Caffeine wakes you up• A mid-afternoon nap is ALWAYS a good idea• You’ll feel great if you sleep as long as possible
  13. 13. Phased Sleeping• Monophasic – Single Large Chunk of Sleep – Example: 10pm – 5:30am• Biphasic – Two Large Chunks of Sleep – Example: 6pm to 9pm / 2am to 5am• Polyphasic – Multiple Small Chunks of Sleep – Example: 30 minute naps at 10pm, 4am, 10am, and 4pm
  14. 14. Naps• Not always as beneficial• Could make up for 1 missed REM cycle• Can make up for sleep debt• Can help you feel refreshed in middle of day• Monophasic sleepers should avoid naps within 6 hours of ideal sleep time• Biphasic sleepers should consider a nap to supplement sleep cycles• Polyphasic sleepers need to be consistent – spontaneous naps could be detrimental
  15. 15. Create a Sleep Plan• How many cycles do you want?• Can you schedule a nap?• How long does it take you to fall asleep?• What time do you need to be up by?Example: I want 5 cycles and can’t schedule a nap, so I need to sleep 7.5 hours at night. I take 15-20 minutes to fall asleep and need to be up by 6am. 6am - 7.5 hours = 10:30pm - 20 minutes = 10:10pm OR 10:00pm + 20 minutes + 7.5 hours = 5:50am Don’t take the extra 10 minutes of sleep!
