If you're waking up naturally at those times, then that's all your body needs. The best way to see your hours is to either start sleeping 30 minutes earlier or later for a few days at a time, check to see if your sleep cycles are consistent and perhaps train your body to sleep more. If you're going to bed at 1am and waking that early, you need to start sleeping earlier! Try some melatonin 30 minutes before bed to help you relax easier.

You can try siestas. A good siesta just after lunch does wonder, and since you're unemployed, you don't have to worry about waking up on time for work.
