Sleepless in Silicon Valley
Tbh the oura ring has been a game changer for a data nerd like me. I can easily see how some exercise in the day actually impacts my HRV[1] and then the quality of my sleep. Had a heavy night of drinking? Watch what the oura ring reports not just on the same night but even the next night :) Basically if you're thinking of starting your own "protocol" for sleep and would like to A/B test what works and what seems like superfluous ceremony, the oura ring is a cost-effective way to measure the effectiveness of said protocol.I think the protocol described in the article isn't anything terribly new. Most folks on HN know that blue light actually messes with sleep so if you're planning on using a screen until right before you goto bed it's a great idea to use the blue-light canceling computer glasses. Mindfulness meditation is generally a great practice to calm oneself and be reflective. I don't personally sleep at 8:45pm (rather, 11:45pm) but I do have my meal a few hours before I goto bed. I also don't drink much water closer to bedtime so I'm not rudely awakened in the middle of the night to urinate. I live in a place where the black-out blinds aren't a necessity. I've never messed with deep sound waves.Of course, some folks will exclaim "Well I don't need a device to give me a report card on how well it thinks I slept!" ¯\_(ツ)_/¯[1] https://ouraring.com/heart-rate-variability-basics/
