The Easy Brain Hack to Lower Divorce Stress (Episode 4)
Why writing a list at 3 a.m. is one of the most underrated tools in divorce — and the neuroscience that makes it work.
A simple, yet effective, way to lower divorce stress is to keep a notebook (paper or phone) within reach and write down random important things as they pop into your head. Could be house‑sale tasks, custody questions, financial to‑dos, anything you don't want to forget. In this 9‑minute episode, therapist Jon Peters, MSW, LCSW, LICSW explains the neuroscience behind why this works: sustained stress shuts down the part of your brain that handles focus and short‑term memory, so your mind starts "juggling" important items as a survival mechanism. And this is likely to wake you up at 3 a.m when you'd rather be peacefully sleeping. Writing items down tells your brain "it's safe to let this go, it's captured," and the juggling stops. Jon has shared this technique with thousands of parents over 30 years, and many report it lowers their stress more than anything else they've tried.

Key takeaways from this episode
Your brain treats important‑sounding thoughts as "balls to juggle." Until something is captured externally, your brain keeps a process running to make sure you don't lose it — which costs you focus, sleep, and energy.
Sustained stress physically diminishes your focus and memory. The right‑front part of your brain (anxious, negative thoughts) gets more active under chronic stress; the left‑front (focus, organization, complex tasks) gets less active. They work in a reflexive relationship — when one goes up, the other goes down.
This is why simple things feel hard during divorce. Grocery lists, work tasks, remembering what you said yesterday — these aren't moral failings. They're predictable symptoms of the brain state divorce puts you in.
The fix is mechanical, not emotional. Capture the thought externally and your brain releases its grip on it.
The 3 a.m. wake‑up cycle has a specific cause. When something feels important and unresolved, your brain refuses to let you fully sleep until it's "saved" somewhere. A notebook on the nightstand interrupts the cycle.
This is not journaling. Journaling processes emotions. This is a capture list — just raw items so your brain stops juggling them.
Prioritize later, capture now. Don't sort by urgency or importance in the moment. The relief comes from offloading; the organization can wait.
How to actually do it
The technique is almost embarrassingly simple. That's the point — it has to be simple enough to do when you're exhausted.
Pick one capture surface. A small paper notebook works. The Notes app on your phone works. Pick one and stick with it — splitting it across five places defeats the purpose.
Keep it within arm's reach at night. Especially during the first 6–8 weeks of acute stress. The 3 a.m. wake‑up is the highest‑value moment to capture.
Write the thought down without editing it. No sorting, no judging, no "is this important enough." If it woke you up, it goes on the list.
Go back to sleep / move on with your day. That's it.
Once a week, sort the list. Pick a regular time (Sunday morning works for many people) to review the list and group items by urgency and importance. Most items turn out to be less urgent than they felt at 3 a.m.
What this is not: it's not a journal, not a therapy substitute, not a place to process emotions. Those have their own role. This is purely a brain offload mechanism.

The grocery store analogy
Jon's framing for why this works is simple:
Imagine you walk into a grocery store needing 12 ingredients for a complex meal and you didn't bring a list. Your entire visit is spent mentally rehearsing the items so you don't forget any of them. By the time you're at checkout, you're exhausted and you've probably forgotten two.
Now imagine you walked in with a written list. The mental load is zero. You glance at the list, grab the item, move on.
Divorce gives you the biggest possible shopping list — house decisions, custody logistics, financial moves, parenting choices, legal steps — and most dads try to carry it in their head while their brain is operating at reduced capacity. That's the source of a huge chunk of your stress.
The neuroscience behind why this works
Two things happen in your brain under sustained stress:
The right‑front becomes hyperactive. This is where anxious, negative, threat‑scanning thoughts live. So you spend more of the day in worry mode.
The left‑front becomes underactive. This is where focus, organization, planning, and complex task management live. So your ability to handle ordinary cognitive work drops.
The two halves operate in a reflexive seesaw — when one is up, the other is down. This is why the same tasks that used to be effortless start feeling like wading through mud during divorce. You're not getting dumber. You're operating with one half of your prefrontal cortex partially offline.
Capturing thoughts externally is a workaround. It moves the "juggling" load out of your already‑overworked left front and onto paper, where it doesn't cost you anything.
