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!
- ideal sleep temperature is 62-65, temps above 75 and below 54 cause people to awaken
- caffeine doubles sleep time
- 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
- 7-9 hours of sleep a night is ideal for optimal health and growth
