“Zeo Sleep Self-Experiments”, Gwern2010-12-28 (, , , , , ; backlinks)⁠:

EEG recordings of sleep and my experiments with things affecting sleep quality or durations: melatonin, potassium, vitamin D etc

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

  10. ZMA: inconclusive results slightly suggestive of benefits
