All the sensible advice for being productive and healthy is around getting a good night’s sleep. Here’s a very articulate post on it – and a good book recommendation – from Tom Tunguz.

I’ve written before about my need for 8 hours’ sleep. What I’ve also found is how close I get to the magic 8 hours is important too:

  • Any more than 8 hours’ sleep and I’m in good shape. If I’ve been in the red on sleep the past few days, and I get 8 hours’ sleep or more, then I’m fine. Then it’s simply a better 8 hours’ sleep than normal
  • If I get less than 7 hours’ sleep, I’m feeling OK, but I need to fix it at some point in the short term. I can’t go more than a couple of days with, say, 6 hours’ sleep
  • If I get between 7 and 8 hours’ sleep, I’m shattered! I feel groggy and it takes me a while to get out of the funk

I can’t explain this, and it presents a dilemma if I have to get up a specific time and the 8 hour window for going to bed has just closed. Do I stay up longer and get less than 7 hours’ sleep, as counter-intuitive as that sounds, or do I go to bed anyway and risk the outcome of getting between 7 and 8 hours’s sleep?
