What a Brain-Healthy Day Actually Looks Like

Morning

Get outside within an hour or so of waking, even briefly. Morning daylight is the strongest signal the body clock takes, and the clock is what organises the sleep that memory consolidation depends on. Ten minutes is enough; it does not require a walk, though a walk covers two items at once.

Eat something with fat in it — an egg, yoghurt, nuts. If you take a daily supplement, this is where it goes, because half the actives in ours need dietary fat to be absorbed at all, and a capsule swallowed with black coffee is largely wasted.

Mid-morning

Put the demanding work here. This is the part of the day when concentration is most available for most people, and spending it on email is the single most common unforced error in this whole area.

Lunch

Smaller than feels natural, with protein in it, and the fast carbohydrate eaten last. Then ten minutes of walking, which is one of the better-evidenced and least-followed pieces of advice available.

Early afternoon

Accept the dip rather than fighting it. Administrative work, mechanical tasks, phone calls. If circumstances allow a twenty-minute nap, take it; if they do not, daylight again is the next best thing.

Late afternoon

Movement, if it has not happened yet. Aerobic activity remains the item with the strongest evidence base in cognitive ageing, and the version that survives is the one attached to a fixed time rather than to good intentions.

No caffeine past the early afternoon. Its half-life runs around five hours, which makes a four o'clock coffee a real presence at nine.

Evening

Company, if it is available. Conversation is harder cognitive work than any puzzle book because the other person is unpredictable and will not wait while you compose your answer. A phone call counts.

Alcohol, if any, early and modest. It shortens the time it takes to fall asleep and then suppresses REM for much of the night, which is a poor trade for anybody interested in memory.

Night

A consistent wake time matters more than a consistent bedtime, and it is easier to hold. If snoring has been mentioned, or anybody has noticed pauses in your breathing, get that investigated properly rather than treating it as background noise.

Which parts actually matter

If that is too much to adopt at once — and it is — the three carrying most of the weight are: get your hearing tested, move most days, and protect sleep. Everything else on this page is a refinement around those three.
