The Science of Sleep (Paralysis)

This is really scary and you probably shouldn’t watch it if you have trouble sleeping. Like I did. Super-interesting nonetheless.

It’s ok though. If you do have trouble sleeping after watching the video, you can download the iPhone app, Sleep Cycle. Pretty much the coolest app I’ve so far used and the best 99 pennies I’ve ever spent. Sleep Cycle is an alarm clock on HGH. It stays in bed with you and actually measures how you toss and turn through the night using the iPhone’s accelerometer. These subtle measurements allow the app to determine what sleep phase you are in. “Waking up in the lightest sleep phase feels like waking without an alarm clock – it is a natural way to wake up where you feel rested and relaxed.” So even though you set the alarm for a certain time, it can wake you up at any point during a 30 minute window, according to what phase you are in. After a while, it learns your sleep patterns and displays them in nightly graphs. You can even annoy your friends by posting the graphs to Facebook!

Naturally, I was skeptical at first, but so far this thing works like gangbusters. Since I started using it, I don’t feel groggy during the day and have had more energy than I know what to do with. Don’t know if it’s magic or psychological or if it just works, but color me a believer. Now I can’t wait to go to sleep. Read more about it here and here.

    Well for me, it gives me confidence knowing that I will be woken up pleasantly.
