When people can’t fall asleep, they usually try harder. They relax more aggressively. They optimize routines. They stack supplements. Sleep science tells a different story. Sleep onset improves not by force, but by reducing the conditions that keep the brain alert. This post synthesizes what research actually supports and what consistently fails.
Most sleep advice sounds reasonable. Much of it fails anyway. That’s not because people are undisciplined. It’s because most advice misunderstands how sleep onset actually works.
Sleep wearables are good at telling you how long you slept. They are much worse at telling you when sleep actually began. That gap matters, because sleep onset is where many sleep problems start.
