Data point: I used to have a 20-min nap after the work, and it helped me to "reset" the brain. The rest of the day felt like a mini-weekend. I need to start this habit again.
The failure mode is when I start going to work late and leaving late, and then I feel like it's too late in the day to take a nap when I get home. I haven't made any effort to determine whether a short nap at, say, 18:30 would make it hard to get to sleep at 22:00.
This is the public group instrumental rationality diary for November 16-30 (that I've now fished out of my drafts folder, *cough*.)
The poll earlier this month seems to be sufficiently in favor of maintaining the current schedule that extra votes are unlikely to change things much, but if you'd really like to register your opinion, you are welcome to do so here.
Thanks to cata for starting the Group Rationality Diary posts, and to commenters for participating.
Immediate past diary: November 1-15
