When you finally slow down at night, fewer external demands are competing for your attention. That can leave more room for everything that’s still open to surface.

Your brain tends to keep unresolved things active because it’s trying to prevent them from being forgotten or mishandled. But when your mind keeps tracking everything at once, it can create cognitive pre-sleep arousal, where your attention stays alert and your working memory keeps pulling tomorrow back online instead of letting it settle. 

Writing helps because instead of asking working memory to keep everything available, you offload it all into an external record. 

The first step in the protocol reduces the pressure to keep rehearsing the list. The second gives each item a future home. The third helps you identify whether there’s a bigger fear underneath the list, and the fourth gives your brain a trusted next step.
