A theory on why “giving in” to insomnia seems to help

I’ve noticed a pattern, people sometimes feel relief when they finally say, “maybe this is just how it is.”
My theory is it’s not the belief that helps… it’s what happens in your body when you stop fighting against insomnia. When you’re constantly trying to fix it- worrying about sleep, health, tomorrow etc., your body stays in a low-level threat mode, guarding you against the fear. Tight, braced, on edge. But when you stop resisting (even a little), your body has the opportunity to soften. Less tension, less urgency. That alone can feel like relief. The interesting part is: You don’t actually have to believe you’ll have insomnia forever… You just need to learn how to relax your body when those thoughts show up. If the thought comes up “what if this never goes away?”, instead of fighting it, try this: Notice where your body is tight. Let your exhale slow down and lengthen. Don’t force the thought away, just don’t tense against it. Train your body to melt into relaxation during your extended exhale, keep doing it for 5 minutes. Over time, this breaks the loop where thoughts → body tension → more fearful thoughts → worse sleep (physical evidence) → belief forms. The goal isn’t to control your thoughts, or even to sleep better. It’s to stop your body from reacting to like you’re under attack. This can break the loop.
