Biphasic Sleep Experiment – Day 7

Just as I noted yesterday, I did not get my usual core sleep yesterday night, due to the unexpectedly long nap. I woke up from that nap at 2:30 am and stayed up all the way until 5 pm, and then took a 90 min nap. I felt really sleepy for much of the earlier day and for a couple hours before I took my 5 pm nap. When I woke up from my nap, I felt extremely refreshed as usual.

So far, so good I guess. Let’s see if I am able to sleep 3 hours now for my core sleep.

Day 7 stats:

  • Core: 0 hrs
  • Nap: 1.5 hrs
  • Cumulative hours slept: 40.5 hrs
  • Average amount of sleep per day: 5.8 hrs
