A brainmaxing routine for one week

Start by writing down where you are. The Cognitive Skills Snapshot takes six questions, scores in your browser, needs no account and produces a ranked list of the areas your answers point at, with the weight behind every answer published. It is free and it stays free. Nothing it gives you is a diagnosis and nothing it gives you is a number about your intelligence; it is a way of choosing what to change first, which is the only decision day one has to make.

Then change exactly one thing. A week in which four habits were attempted and none was kept teaches you nothing about any of them. The rest of this page is a menu in evidence order, and the instruction is to take the top item you are not already doing.

Pick a bedtime and a wake time you can keep on a bad day as well as a good one, and keep the wake time fixed. That is it; that is the change.

It is first because the evidence underneath it is the strongest thing in this field and the least interesting to read. Pooling seventy studies and 147 cognitive measures, Lim and Dinges (2010) found short-term sleep deprivation degraded performance across attention, working memory and processing speed, with the largest effects on lapses in simple attention — the moments where nothing happens for a second and a half [1]. Those are experiments on deprivation rather than trials of improvement, which is exactly what the claims table at the foot of this page says.

What follows for a week of yours is modest and worth having: the difference between a short night and a normal one is visible on tasks as plain as pressing a key when a light changes, and it is far larger than the difference any supplement in this category has shown in healthy, rested adults.

Walk briskly, cycle, swim or lift for the length of time you will still be doing in a month. The pooled picture in healthy people is a small effect on cognitive measures from sustained exercise programmes, and Ludyga and colleagues (2020) found it was moderated more by who was exercising and for how long the programme ran than by any clever choice of exercise [2].

Read that as a reason to pick something repeatable rather than something optimal. A thirty-minute walk you take three times a week for a year is inside the evidence; a programme you abandon in week two is not in it at all.

If any part of your week involves learning something, this is where the largest, cheapest win in the literature sits, and it is a change of method rather than of effort.

First: close the book and try to produce the answer before you check it. Dunlosky and colleagues (2013) graded ten common study techniques by how well they hold up across materials, learners and conditions, and practice testing and distributed practice came out highest, with re-reading, highlighting and summarising among the lowest [3].

Second: separate the attempts in time. Cepeda and colleagues (2006) pooled the distributed-practice literature and found spaced study reliably beat the same amount of study massed together, with the best gap depending on how long you need to remember it for [4]. A gap that feels uncomfortably long is usually the right one.

Interleaving — mixing problem types instead of doing them in blocks — is the third technique people reach for, and it is the one with a condition attached: Brunmair and Richter (2019) found it helps when the things being mixed are genuinely confusable, and helps much less when they are not [5]. So mix the things you keep mistaking for one another, and block the rest.

Put the phone in another room for one working block, at the same hour, and note how long you lasted before attention broke. This is the one step with no citation attached to it on this page, and it is written that way on purpose: the honest status of the media-multitasking literature is that it is mostly correlational, so what you get from it is a hypothesis about yourself that one week can test.

That is also the shape of the product's own seven-day protocols, which is where this day comes from: a change you can make tonight that costs nothing, followed by a measurement of whether it did anything for you.

Look back at what actually happened rather than at what was planned. Which day went best, and what was different about it? Keep that, drop the rest, and carry exactly one habit into next week.

If you played anything on the bench during the week, compare your runs with your own earlier runs on the same device and nothing else. There is no norming sample behind any of those numbers, so they carry no percentile and place you against nobody — and a run after a short night tells you something about the night rather than about you.

No supplement is prescribed here, and the site's own notes on the ones people ask about say why: outside a deficiency or a strain condition the effects reported in healthy adults are small, inconsistent and measured on laboratory tasks. No device, no app subscription and no course is needed either. If a step in a routine requires a purchase, the purchase is the product and the routine is the advertisement.

Nothing on this page is medical advice, nothing here diagnoses or treats any condition, and none of it is written for anyone under eighteen. If you are worried about your memory or your attention, that is a conversation to have with a clinician rather than with a browser game.

A grade belongs to one claim, in one population, for one preparation — never to a compound, a technique or an article. The weakest link is the part of the chain between the evidence and the thing you would actually do that is doing the least work.
