Have you ever wondered why you feel better rested when you sleep less hours than the previous night when you got plenty of sleep? It might have less to do with the number of hours, and more to do with when you wake up. If you wake up in the middle of a sleep cycle you will not be happy, but if you wake up at the end of a sleep cycle you will rise for your day refreshed and rested. Each sleep cycle is about an hour and a half in length.
We found a really nifty website that calculates what time you should fall asleep depending on the time you need to wake up. Once you type in the time you need to rise, it gives you four different options. This will ensure that you complete a sleep cycle before that dreaded alarm goes off.
