ZEO SLEEP SELF-EXPERIMENTS gwern.net/Zeo

https://www.gwern.net/Zeo

I discuss my beliefs about Quantified Self, and demonstrate with a series of single-subject design self-experiments using a Zeo. A Zeo records sleep via EEG; I have made many measurements and performed many experiments. This is what I have learned so far:

  1. the Zeo headband is wearable long-term
  2. melatonin improves my sleep
  3. one-legged standing does little
  4. Vitamin D at night damages my sleep & Vitamin D in morning does not affect my sleep
  5. potassium (over the day but not so much the morning) damages my sleep and does not improve my mood/productivity
  6. small quantities of alcohol appear to make little difference to my sleep quality
  7. I may be better off changing my sleep timing by waking up somewhat earlier & going to bed somewhat earlier
  8. lithium orotate does not affect my sleep
  9. Redshift causes me to go to bed earlier
