When a member of the hotel team showed me around my sleep-optimized room at Switzerland's Chenot Palace Weggis, I got the sense I would not sleep very well at all. “You set the alarm for the morning and it will play for 20 minutes,” she explained, pointing to a panel on the wall. “Then you put on the eye mask and play this for another 20 minutes.” She gestured toward a smartphone on the other side of the bed that contained the app I would need. There was also a smart thermostat, which had to be set between 66 and 68 degrees, bedsheets coated with infrared-emitting minerals, and temperature-regulating pajamas. I was tired, jet-lagged, and in no shape to comprehend the complicated contraptions that were meant to help me do what's supposed to be the most natural thing in the world.
