Why do I feel more awake with less sleep?
Feeling better after less sleep – including after getting less Deep or REM sleep – could be the result of your body trying to compensate for sleep deprivation. When you’re short on sleep, your body releases stress hormones the next day and evening. These hormones supply the sensation of alertness.
How long is a power nap?

Is it better to stay up all night or get 2 hours of sleep?
Grabbing two hours of shut-eye will help your brain and body recharge enough to make it through the day. Do yourself a favor and take a two-hour siesta.
