Researchers say consistency matters more than a magic number — and that quality beats quantity.

Analysts point to a handful of forces driving the story forward:

  • Consistency over raw duration
  • The cost of social jet lag
  • Small habits with big payoffs

The best sleep advice, researchers say, is also the most boring.
