Wow, I haven't been signed into LW in awhile.

Zeo has typically recorded about 2h each of REM, Light, and Deep sleep during my core, plus 8 mins REM during my naps.

I finally started actually charting this stuff just about a month ago, and so far can report: (all times in minutes)

Average bedtime = 230 minutes past midnight (stddev 62)

  • REM = 124 (25)
  • Light = 122 (28.6)
  • Deep = 104 (14.8)

Nap typically 229.6 minutes after wake (76)

  • REM = 124 (25)
  • Light = 122 (28.6)
  • Deep = 104 (14.8)

I am totally not a statistician, but models of sleep and my own data definitely support the conclusion that I get much more deep sleep when I go to bed earlier. Given this, I really need to start doing that. The three datapoints I have where I went to bed by 2:30, I got >= 2h deep, which only happened in one later-bedtime case (during which I also slept 7h total, fwiw, due to having missed a nap or something).

So I predict that when I start sleeping earlier I'll be back to the 2h of deep I mentioned initially.

I'm happy to throw this data at you for analysis. In theory my zeo has been logging it since over a year ago (and decrypted, thank god) but I don't know how to get it off so I've just been logging it in a spreadsheet daily. If you want the raw zeo file, you can have that too.

Yes please. What questions did you have in mind?

In theory my zeo has been logging it since over a year ago (and decrypted, thank god) but I don't know how to get it off so I've just been logging it in a spreadsheet daily. If you want the raw zeo file, you can have that too.

If it's decrypted, then you can use the ZeoDataDecoder Java library to convert it to CSV (see https://forum.quantifiedself.com/thread-zeo-shutting-down-export-your-data ). It's what I use for my own data right now. It's a little annoying to set up the dependencies in Debian because the error messages are opaque, but not that bad.
