Your body

If your attention runs low on stimulation, salty and sweet food is the fastest legal source of a lift and it is available all day. Worth knowing about yourself, because it explains a pattern that willpower alone never seems to touch.

Rates of overweight and type 2 diabetes are higher in people with ADHD, and the reasons are not moral ones. A reward system that is under stimulated…

Caffeine buys about half an hour of sharper focus and takes the payment out of your sleep. It is a decent tool for a particular hour, and using it in place of treatment usually leaves you worse off across the day.

Four cups a day and upwards starts producing insomnia, irritability, tremor, an unsettled stomach and a racing heart, and a few people go sleepy on…

Very low vitamin D produces fatigue, low mood and a flatness that looks exactly like depression, and it is not part of routine bloods in most places. If you have never had it measured, it is a fair thing to ask for.

One clinician telling this story about himself had a level that was almost undetectable, and no antidepressant would have raised it, because what was…

The vitamin D in a general multivitamin is a maintenance amount, nowhere near what is used to correct a real deficiency. If your level is genuinely low, that is a prescribing conversation with blood tests behind it, not a shelf in the chemist.

Correcting a deficiency usually means a high dose for a defined period and then a steady daily amount, with the level rechecked to see where you have…

Before settling on depression as the whole story, ask for thyroid function and vitamin D to be checked. Both are common, both are cheap to test, and an underactive thyroid produces a picture that looks like depression from the outside.

An untreated thyroid problem also blunts how well antidepressants work, so missing it can mean months on a treatment that was never going to do the…

If a health habit keeps sliding, attach something immediate to it. The apps where you put real money on hitting a step target work for a reason: the payoff arrives now instead of in twenty years.

The natural reward for walking more is invisible and decades away, which is no use to a brain running on what happens next. A small stake, a streak,…

Before settling on a purely psychological account of months of anxiety or broken sleep, it is worth having the ordinary bloods done. Low iron, low vitamin D or low magnesium can produce symptoms that look exactly like a mental health problem.

This is not about swapping therapy for supplements. It is about not spending a year working on something a blood test could have partly explained. If…

A child struggling with attention, anxiety and daily reflux at once may be dealing with one problem wearing three coats. Undiagnosed coeliac disease and other food reactions can produce all of it, and the gut symptom is the clue worth following.

Symptoms that arrive together are worth asking about together. If reading, mood and stomach all went wrong over the same period, that pattern is…

Move earlier in the day if you can. Whatever it gives you is then available for the hours that follow, and the day has fewer chances to swallow it.

Evenings fill up with everything that got postponed, and the session is usually first to go. Morning does not have to mean dawn: before work, after…

Put music on. A faster tempo pulls your pace up without you deciding to, and the same effort feels lighter when there is something to listen to.

Make a short list you genuinely like and save it for moving, so it does not turn into background. Podcasts and audiobooks do a similar job if music…

Arrange to meet someone. A neighbour at the gate at eight, a friend expecting you, even an app counting a streak. Turning up for someone else is easier than turning up for yourself.

Benefits that arrive in six months are weak motivators. Something that pays out today works better: a person waiting, a number that goes up, a…

Being outside gives your attention something to rest on rather than something to hold. That is why an hour outdoors leaves you clearer than an hour lying on the sofa.

Indoors, most of what you look at wants something from you. Outdoors, leaves moving, water, birds, the light changing, all of it holds you without…

You do not need greenery for outside to help. Snow, grey sky, bare trees, a car park at dusk. Getting out still does something.

This matters if you live somewhere that is brown and frozen for half the year, or in a city with more concrete than park. Wrap up, go out for fifteen…

No particular kind of movement wins. Balance work, martial arts, tai chi, swimming, all of it helps about as much, and what predicts the benefit is moving regularly at all.

This is good news, because it means you can stop researching and start doing. Pick whatever you have access to and will still be doing in a month. If…

Learn a long sequence in small pieces and join them up afterwards. Nobody should be holding twelve steps in their head at once.

Take the first two moves until they are boring, then add the third. It feels slower and it is not, because the version learned this way stops falling…

Doing the identical sequence every time is not boring for everyone. For some people the sameness is precisely what settles them.

Tai chi runs the same series again and again, and there is nothing to decide once you know it. It is a bit like having a programme on that you have…

A hard walk or a run works a little like a small dose of something. Alertness up, mood up, for a while afterwards.

This is a useful way to think about it because it puts movement in the category of things that do something to you, rather than things you ought to…

Movement gives you back some willingness, not just some focus. The problem is often not that you cannot concentrate but that you cannot make yourself care enough to start.

Those are two different difficulties and the second one is usually the more disabling in adult life. After moving, the same task tends to feel…

Bolt the movement onto something you would want to do anyway. A game with a friend, a walk to somewhere with good coffee at the end, a route past the river.

People keep up a weekly game with a mate for forty years and never once call it exercise. The friendship is what they turn up for and the moving…

The best exercise is whichever one you go back to. Something you enjoy, outdoors if you can, with other people if that helps, and above all something you will do again on Thursday.

There is always a more efficient programme on paper. It does not matter if you stop after a fortnight. Judge any plan by whether you would still be…
