8 Simple Steps to the Perfect Nap – According to Dr James Maas

  1. Decide if you really need one. (If you are getting adequate nighttime rest —7
    ½ to 9 ½ hours—you shouldn’t need one.)
  2. Choose between 20 or 90 minutes. (Anything in between will leave you
    feeling worse.)
  3. Set a dependable alarm.
  4. Eliminate disturbing noise by wearing earplugs or turning on something that
    generates ambient sound (i.e., air conditioner, fan, radio set between
    stations.)
  5. Block light by pulling shades or wearing an eye mask.
  6. Cool the room to 65-68 degrees Fahrenheit.
  7. Lie down. (Trying to nap while sitting in an unsupported position keeps
    muscles from fully relaxing.)
  8. Clear your mind as best you can.
