Sleepless in Silicon Valley

摘要

First, close the blackout blinds in your bedroom. Eat dinner at 4pm, and do not eat or drink anything after 6pm. Put on your blue-light blocking glasses at 8pm. Set your bedroom temperature to 67°F (19.4°C) and your electric blanket to 69.8°F (21°C). At 8.45pm, meditate for five to ten minutes. Switch on your deep-wave sound machine. Put on your Oura sleep-tracking ring. You are now, finally, ready for slumber. This may all sound a bit over the top. But this is the "sleep hygiene" routine described in a recent blog post by Bryan Johnson, who sold his previous company to eBay for $8oom and is now chief executive of Kernel, a startup developing brain-computer interfaces. He admits that his sleep routine has "decimated my social life", and that his partner sleeps in a different room, but says all this trouble is worth it, because it has boosted his level of "deep sleep" by as much as 157%. He has bought Oura rings for all his employees.
