Your child's brain needs more than revision

When exams are approaching, it is easy for everything at home to become about revision. There are books on the kitchen table, flashcards scattered around the bedroom and a revision timetable stuck to the wall. Your child has another topic to cover, another set of questions to practise and another hour that could apparently be spent studying. But there is something we sometimes forget when we talk about effective learning: your child's brain is attached to a body. It doesn't learn in isolation.

How much your child sleeps, what they eat and drink, how much they move and whether they give themselves time to recover can all affect the conditions in which learning takes place. That doesn't mean your child needs to become an elite athlete or follow a perfect diet during exam season. It simply means that spending every available minute at a desk isn't necessarily the best way to prepare.

More revision isn't always more learning

Imagine your child has been sitting at their desk for three hours. They are tired, hungry, thirsty and increasingly distracted, but they keep going because they think another hour of revision must be better than stopping. It sounds productive. But learning isn't measured by how long your child sits at a desk. What matters is what their brain is actually doing during that time.

If they are struggling to concentrate, staring at the same page or simply going through the motions, another hour may not be particularly valuable. Sometimes the best thing they can do is step away from the desk and give their brain and body a chance to recover. This is one of the reasons taking breaks is part of effective studying rather than just seeing it as a reward for finishing it.

Get them moving

Exercise might not look like revision, but that doesn't mean it has nothing to do with learning. Physical activity can improve mood, reduce stress and help children feel more alert. It can also support sleep, which we know is an important part of learning and memory. The good news is that this doesn't need to mean an hour in the gym or a carefully planned training programme. A walk, a game of football, going for a run, riding a bike, practising a sport or simply getting outside for a while can all provide a useful break from sitting at a desk.

If your child has been studying for a couple of hours, encouraging them to get up and move around might be much more useful than telling them to sit down and do another 30 minutes.

Don't underestimate water

Hydration is another simple thing that can easily get forgotten when children are concentrating on revision. Your child's brain needs water to function properly, and even mild dehydration can leave someone feeling tired, uncomfortable or less able to concentrate. That doesn't mean drinking huge amounts of water will suddenly make your child remember everything they have revised. It simply means that being thirsty isn't a particularly good condition for learning.

So make it easy. Have a bottle of water available while your child is studying. Encourage them to drink regularly rather than waiting until they are really thirsty, and make sure they have something to drink when they go into an exam where this is permitted. It is a very small intervention, but sometimes the simplest habits are the easiest ones to maintain.

Be wary of the energy drink shortcut

When children are tired during exam season, an energy drink can seem like an obvious solution. They are marketed as something that will give you energy and help you keep going, which can make them particularly tempting when your child feels they need another late-night revision session. But more energy isn't necessarily the same thing as better learning.

Energy drinks can contain substantial amounts of caffeine and sugar, and too much caffeine can leave some children feeling jittery, restless or unable to sleep properly. That creates a rather unhelpful cycle: your child drinks something to stay awake and revise, then struggles to sleep, feels exhausted the next day and reaches for another boost. That is hardly a recipe for effective learning.

If your child is exhausted, the answer isn't necessarily to find something that helps them stay awake for longer. Sometimes the better answer is to stop studying and get some sleep.

Your child doesn't need to study like a machine

There is a strange idea that successful revision means sitting at a desk for hours without interruption. Perhaps it comes from the way we sometimes talk about hard work. If you are working harder than everyone else, you must be more likely to succeed. But effective learning isn't about seeing how long your child can remain seated with a textbook open. Their brain needs periods of concentration, but it also needs sleep, movement, food, water and time away from the task. These things aren't distractions from learning. They are part of creating the conditions in which learning can happen effectively.

Think about a professional footballer preparing for an important match. They don't spend the 24 hours beforehand running around as much as possible because they want to maximise their preparation. They think about training, nutrition, hydration, recovery and sleep because they understand that performance depends on all of those things working together. Your child might not be preparing for a football match, but the principle is similar.

Breaks aren't wasted time

This is particularly important for parents because it can be tempting to worry when your child takes a break. You might see them go for a walk and think, "Shouldn't they be revising?" You might see them playing sport and think, "Their exams are next week." You might even feel slightly uncomfortable when they finish studying earlier than you expected. But if the alternative is another hour of tired, distracted and ineffective studying, a break might actually be the more productive choice. A useful question isn't "How many hours has my child revised today?" It is "How effectively did they use the time they spent learning?" That is a much better measure.

Help them find a balance

None of this means that revision isn't important. It is. Your child still needs to learn the material, practise retrieving it and prepare properly for their exams. Exercise, food, water and sleep can't replace effective study. But neither can effective study replace the basic things the brain and body need to function well.

This is where parents can help. Rather than constantly asking, "Have you done enough revision?", you can sometimes ask a different set of questions. Have you had a drink? Have you eaten? When did you last get outside? Do you need a break? What time are you planning to finish tonight? Those questions aren't taking your child's eye off the importance of their exams. They are helping them understand that looking after themselves is part of preparing for them.

The best revision plan includes more than revision

When your child is under pressure, it can feel as though every minute away from their books is a minute wasted. But learning doesn't happen simply because someone is sitting at a desk. Your child's brain needs attention, effort and practice, but it also needs the rest of the body to be functioning reasonably well. That means getting enough sleep, drinking water, eating properly, moving regularly and taking sensible breaks.

So if your child is studying hard, don't feel guilty about encouraging them to put the books down for a while. Get them outside. Give them something to drink. Let them move around. Make sure they eat properly. And if they are exhausted, encourage them to go to bed rather than reaching for another energy drink.

Sometimes the best thing your child can do for their revision is stop revising for a while.
