Lighten the cognitive load. "Getting Things Done" by David Allen is the gold standard for externalising mental load into a trusted system — reducing cognitive overhead dramatically.
Mental load (also called cognitive load or the "mental juggle") refers to the invisible, ongoing cognitive work of managing all the things in your life — not just doing them, but holding them in mind, tracking their status, anticipating what needs doing next, and worrying about what might go wrong. It's the browser tab that never closes.
Mental load research shows it disproportionately affects women in partnerships, but it's an issue for anyone who is the primary planner and tracker in their household or team. The most effective relief comes from externalising the load (into systems, apps, shared lists) rather than trying to hold it all in your head — this is why GTD and similar frameworks work so well.
The three most effective strategies: 1) Externalise it — put everything into a trusted external system (lists, calendar, apps) so your brain isn't trying to track it all. 2) Delegate genuinely — not just the task but the responsibility for thinking about it. 3) Prioritise and deprioritise — acknowledge that some things can wait or be dropped entirely. Perfectionism significantly increases mental load for no return.
The brain uses approximately 20% of the body's energy despite being 2% of its weight. Sustained cognitive processing — holding multiple open loops, making decisions, anticipating problems — is genuinely metabolically expensive. Chronic mental overload activates the stress response, raising cortisol and adrenaline, which causes physical symptoms: fatigue, headaches, muscle tension, disrupted digestion. The physical exhaustion from mental load is physiologically real, not imagined.
