Tools for Sleep
We go through a variety of cycles from light to heavy sleep
and it seems that when we wake up in a lighter sleep you are not as tired throughout the day.
The website sleepyti.Me has a calculator to find an optimal time. There are a variety of monitors that you can buy such as jawbone's up or the zeo at around $99. They track your sleep waves and try to wake you up during lighter phases of sleep.
