sleep!

Since I am a college student, this blog about sleep was a must have topic for me!

We as humans spend 1/3 of our lives sleeping!

Now, according to a study,
individuals with severe sleep deprivation ( staying awake 19-24 hrs ) scored worse on performance and alertness tests than people who are legally too drunk to drive (0.1 % )

Symptoms of Sleep Deprivation:

  • day time drowsiness
  • sleepy while reading
  • sleepy while watching tv
  • if you fall asleep the instant your head hits the pillow ( a well rested person only takes 15/20 minutes to fall asleep)
NREM sleep ( non rapid eye movement ) 75% of sleep time
  • stage 1- relaxed/ half awake (10 sec-10 mins)
  • stage 2- brain activity slows, you stop moving (10-20 mins) beginning of your actual sleep
^ - people awaken during these two stages say that they weren't really sleeping
  • stage 3/4- blood pressure drops, heart rate and respiration slow, blood to brain shorten (20-40 mins)
^- people awaken in stage 4 feel groggy,  your in a "deep sleep"

REM sleep ( rapid eye movement ) 70-90 minutes after falling asleep
  • breathing and heart rate go up
  • brain activity is similar if you were awake
  • experience first dream ( although you can in all stages )
  • no muscle tone
  • body can't move
  • ideas are filed in long term storage
- if you sleep for 8 hours, your body cycles 5 times in the sleep cycle of NREM & REM

** IMPORTANT**
- memory may be impaired if sleep time is insufficient, as a result to memory impairment, the ability to learn new skills is also impaired. performance in learning a new skill does not improve until an individual has had 6 hours of sleep; performance improves even more after 8 hours of sleep!
  
things to remember when trying to get a good nights rest!
  1. ideal sleep temperature is 62-65, temps above 75 and below 54 cause people to awaken
  2. caffeine doubles sleep time
  3. take no longer than 45 minutes of naps, you'll enter stage 4 of deep sleep and it will be more difficult to wake you up and you will feel more groggy
  4. 7-9 hours of sleep a night is ideal for optimal health and growth 
Email me if you have any questions and need help on falling asleep and how to get a propers nights rest!
hope you were somewhat informed!!
