Sleepless in Silicon Valley

But this is the “sleep hygiene” routine described in a recent blog post by Bryan Johnson, who sold his previous company to eBay for $800m and is now chief executive of Kernel, a startup developing brain-computer interfaces. Mr Johnson does not expect other people to copy his routine, but made it public to encourage the sharing of sleep habits and tips. As well as electric blankets and mattress-chillers, sound machines and smart rings, there are also smart pillows, sleep-tracking watches and bracelets, intelligent sleep masks, brain-stimulating headbands, bedside sleep sensors and countless sleep-monitoring apps.
