The 10-3-2-1-0 Sleep Formula Got TikTok Convinced It's a Game-Changer

Somewhere between the 2 a.m. doom-scroll and the fifth energy drink of the day, TikTok discovered what might be the easiest sleep hack to actually remember: a numbers game called 10-3-2-1-0.

The formula's simple. Ten hours before bed, no more caffeine. Three hours out, stop eating. Two hours before sleep, shut down work. One hour prior, ditch the screens. And zero — that's how many times you should hit snooze when the alarm goes off. That's it.

Millions of people are posting about it, swearing it's changed their sleep game. Experts weigh in on what actually works in the formula and what's just internet noise. The science check matters here — some parts track, some are more personal preference than hard rule.
