Sleep and your_brain.
   We apparently spend one third of our lives doing
    nothing
   If you take a look at what is happening inside of
    your brain, however, you will find quite a different
    situation
   When we sleep well, we wake up feeling refreshed
    and alert for our daily activities. Sleep affects how
    we look, feel and perform on a daily basis, and
    can have a major impact on our overall quality of
    life
 Why does sleep matter?
 We sleep for 1/3 of our lives, so it must be
  important.
 Yet scientists are only starting to understand it.
 “The brain is in a constant state of tension between
  cells and chemicals that try to put you to sleep and
  cells and chemicals that try to keep you
  awake.”(Brain)
   The brain is def not inactive while you are sleeping.
   Neurons are busy working all night
   The neurons of your brain show strong rhythmical
    activity when you're asleep
     › perhaps replaying what you learned that day
Sleep and your_brain.
   Sleep patterns vary from person to person
   If you are a morning person, you are among the
    10% of people.
   If you are a night person, you are among 20% of
    the people.
   If you aren't really either of these, you are among
    70% of the people
 Have you ever gone to sleep with something on
  your mind, then woke up knowing the answer?
 Sleep actually can help boost learning
  significantly.
 The phrase “Let’s sleep on it” is such a great help!
   Sleep Loss tears down all of the thinking
    in your brain including:
    › Attention
    › Functioning
    › Memory
    › Skills
    › Math
    › Logical reasoning
 Eventually, sleep deprivation can mess
  up your motor skills such as walking.
 “Studies suggest that sleep loss and
  fatigue result in significant
  neurobehavioral impairments in healthy
  young adults.”(Univ.)
 “This is when NREM begins that is 75% of
  your sleep.” (How) It has 4 stages.
 Stage 1 :
    › Between being awake and falling asleep
    › Light sleep
   Stage 2 :
    › Becoming disengaged from surroundings
    › Breathing and heart rate are regular
    › Body temperature drops (so sleeping in a
      cool room is helpful)
   Stage 3 & 4 :
    › Deepest and most restorative sleep
    › Blood pressure drops
    › Tissue growth and repair occurs
    › Hormones are released, such as: Growth
      hormone, essential for growth and
      development, including muscle
      development
 After the NREM sleep happens, it turns
  into REM sleep which takes up 25% of
  your sleep.
 This stage:
    › Provides energy to brain and body
    › Brain is active and dreams occur
    › Body becomes immobile and relaxed, as
      muscles are turned off
    › Eyes dart back and forth
   “REM sleep may constitute a
    protoconscious state, providing a virtual
    reality model of the world that is of
    functional use to the development and
    maintenance of waking consciousness”
    (Hobson).
   This video describes why your brain needs a
    nap every once in a while.

   http://youtu.be/m_PiKXwGmo8


   “People vary in how much sleep they need
    and when they prefer to get it, but the
    biological drive for an afternoon nap is
    universal.” (Brain)

     › This website gave me some really useful information about the NREM sleep and the
         REM sleep.

    declarative-memory-light-sleep>.
     › This website gave me a good picture of what the two stages of sleep really looked
         like. I have the picture of the two brains going under the two different types of
         activity.



   "Brain Rules: How Our Brain Works?" Squidoo : Welcome to Squidoo. Web. 13 Feb. 2012.
    <http://www.squidoo.com/brain_rules>.
     ›   This article gave me some really useful information about what your brain is doing while you are
         sleeping.

     › This peer reviewed article gave me some great information about what happens
         when you don’t get enough sleep.

     •   This peer reviewed article gave me very good information about dreams and what
         happens when you are in the REM state of sleeping.

Sleep and your_brain.

  • 2. We apparently spend one third of our lives doing nothing  If you take a look at what is happening inside of your brain, however, you will find quite a different situation  When we sleep well, we wake up feeling refreshed and alert for our daily activities. Sleep affects how we look, feel and perform on a daily basis, and can have a major impact on our overall quality of life
  • 3.  Why does sleep matter?  We sleep for 1/3 of our lives, so it must be important.  Yet scientists are only starting to understand it.  “The brain is in a constant state of tension between cells and chemicals that try to put you to sleep and cells and chemicals that try to keep you awake.”(Brain)
  • 4. The brain is def not inactive while you are sleeping.  Neurons are busy working all night  The neurons of your brain show strong rhythmical activity when you're asleep › perhaps replaying what you learned that day
  • 6. Sleep patterns vary from person to person  If you are a morning person, you are among the 10% of people.  If you are a night person, you are among 20% of the people.  If you aren't really either of these, you are among 70% of the people
  • 7.  Have you ever gone to sleep with something on your mind, then woke up knowing the answer?  Sleep actually can help boost learning significantly.  The phrase “Let’s sleep on it” is such a great help!
  • 8. Sleep Loss tears down all of the thinking in your brain including: › Attention › Functioning › Memory › Skills › Math › Logical reasoning
  • 9.  Eventually, sleep deprivation can mess up your motor skills such as walking.  “Studies suggest that sleep loss and fatigue result in significant neurobehavioral impairments in healthy young adults.”(Univ.)
  • 10.  “This is when NREM begins that is 75% of your sleep.” (How) It has 4 stages.  Stage 1 : › Between being awake and falling asleep › Light sleep
  • 11. Stage 2 : › Becoming disengaged from surroundings › Breathing and heart rate are regular › Body temperature drops (so sleeping in a cool room is helpful)
  • 12. Stage 3 & 4 : › Deepest and most restorative sleep › Blood pressure drops › Tissue growth and repair occurs › Hormones are released, such as: Growth hormone, essential for growth and development, including muscle development
  • 13.  After the NREM sleep happens, it turns into REM sleep which takes up 25% of your sleep.  This stage: › Provides energy to brain and body › Brain is active and dreams occur › Body becomes immobile and relaxed, as muscles are turned off › Eyes dart back and forth
  • 14. “REM sleep may constitute a protoconscious state, providing a virtual reality model of the world that is of functional use to the development and maintenance of waking consciousness” (Hobson).
  • 15. This video describes why your brain needs a nap every once in a while.  http://youtu.be/m_PiKXwGmo8  “People vary in how much sleep they need and when they prefer to get it, but the biological drive for an afternoon nap is universal.” (Brain)
