Swap city noise for birdsong at the Chongming Forest Sleep Challenge 2026, where the only goal is to disconnect and get some quality rest. Held in Dongping National Forest Park, participants spend the afternoon offline while professional sleep-monitoring equipment tracks who falls asleep fastest and who racks up the best overall sleep score. Prizes include a 3,000rmb “Supreme Sleeper” award, a 2,000rmb “Fastest to Fall Asleep” prize, and a shared bonus pool for those who make it through the full challenge. With sessions running across multiple weekends and limited spots each round, the event turns doing absolutely nothing — in a quiet forest, no less — into a surprisingly competitive (and slightly surreal) weekend activity.
