This YouTube talk critiques common approaches to sleep tracking in the biohacker community and presents a three-part framework for doing sleep work correctly: (1) explicitly define what "good sleep" means for the goal at hand, (2) measure that specific construct using appropriate (ideally gold-standard) methods, and (3) interpret results in the context of individual factors (sex, age, travel/time-zone changes, cognitive load). The speaker warns that many trackers and analyses fail at the measurement and interpretation steps (e.g., treating REM metrics as meaningful when REM is not being measured correctly).

One of the things we see in the biohacker space is a huge problem with one of those three areas. If we're going to be working on sleep, we have to understand, number one, how are we defining good sleep? Now we're going to go on the path of saying, what is the most accurate way to measure that specific thing? Are we using gold standard scientific methodology to measure that? If not, then we're not going to play the game of REM sleep because we're not even measuring it appropriately. Then the second thing is, how do I interpret it? So interpretation is everything. What should it be for you? Are you male? Female? Are you 35 years old? Are you 65 years old? Do you travel internationally? Are you dealing with time changes? Because. Because I promise you right now, your REM sleep will change based upon your cognitive load.
