my sleep cycle

when i was in atlanta in january willis told me about a new iphone app that he'd purchased that monitors your sleep.  you tell the app that you're going to sleep, then put the phone on your bed for the night.  when you turn over or move, the app registers that and thinks you are either (a) in a less deep sleep than before, or (b) awake, based on the amount of movement.  after he used it the first night and we pored over the results, i obviously had to buy it.  99 cents!  fun information about yourself!

the app rates your sleep from 0% to 100% based on...i don't know what, because sometimes it is wrong.  i'll wake up thinking i had been tossing and turning, but the app doesn't care and rates my sleep as very good.  who knows.  i love it anyway.  i think it must have something to do with how long you are in "deep sleep" and how often you wake up...

this is my best night of sleep, according to the app:

it clearly took me like 45 minutes to fall asleep, but somehow that didn't matter...

and this is my worst night of sleep so far:

i didn't get into the deep sleep very much at all, so apparently it was not pleased.

also, let's note that i am kind of the luckiest person ever, because i consistently get at least 8 hours of sleep a night.  the reason for this: i never have class before 9am.  i'm going to enjoy this life while i can.

you can also tell the app if you worked out or drank caffeine or whatever (you add the options) and then it will tell you if you sleep better or worse after doing these things. the app says i sleep 5% better when i work out and negligibly better if i drink caffeine with dinner, but both are based on just a couple data points, so could presumably change over time.

and that, friends, is probably more than you ever wanted to know about my sleep.
