I'm more of a morning person, I will usually wake up (naturally, without an alarm clock) around 6am, which gives me a few hours to get some work done without any distractions.

I put my information into this survey, and it shows a dip in my "alertness" around 3pm. I've heard that a good way to calculate this is to figure out the midpoint of your normal sleep time (so if you go to bed around midnight and get up at 8am, your midpoint is 4am) then add 12 hours. I've found that napping briefly (10-15 minutes) around this time gives me a lot more energy in the afternoons/evenings.

Having a siesta seems to be hard-wired into us

Good! I crash harder at 5:00 pm than at any time during the night. Glad to see there's a good reason for that.

I also like having a "siesta". Breaks my day into two distinct and effective work sessions.

I always wondered about that too - I talked to Jim a few years ago and was extremely interested in his research into circadian rhythm, travel adapation etc. Very interesting subject area.

I'm a night person, but if I force myself to get up early and go for a run then immediately after I am at my most alert, no matter it is 12 hours away from what is usually my most productive time of the day. I guess cave people didn't have a choice when it was time to run from a sabre-toothed tiger.

At least not the cave people that survived.
