As exams draw closer, something strange tends to happen. Students start cutting back on the things that actually keep them going - sleep gets shorter, exercise disappears, time with friends feels like a guilty luxury. Revision fills every gap, and anything that isn't studying starts to feel like falling behind.
I've seen this pattern play out year after year, and I want to challenge it. Not because exams don't matter - they absolutely do - but because sacrificing your wellbeing in the name of revision is one of the least effective things you can do for your results. The science backs this up, and so does two decades of watching students prepare for high-stakes assessments.
Here's the truth: looking after yourself isn't a distraction from exam preparation. It is exam preparation.
The science of stress and memory
When you're under prolonged stress, your body releases cortisol - the stress hormone. In small doses, this is actually helpful. A bit of pressure sharpens focus and motivates action. But when stress becomes chronic, cortisol starts working against you in a very direct way.
High cortisol levels interfere with the hippocampus - the part of the brain responsible for forming and retrieving memories. In other words, chronic stress actively damages the very processes you need to revise effectively, recall information in an exam, and perform under pressure.
Sleep is where this becomes critical. During sleep - particularly deep sleep - your brain consolidates the information you've taken in during the day, transferring it from short-term working memory into long-term storage. Cut sleep short, and you don't just feel tired. You lose a significant chunk of the revision you did the day before.
Exercise works in the opposite direction. Physical activity triggers the release of BDNF (brain-derived neurotrophic factor), which supports the growth and maintenance of brain cells and strengthens memory formation. Even a 20-minute walk can improve concentration and reduce anxiety for hours afterwards.
The irony is this: the students who drop everything to revise around the clock are often the ones who retain the least. The students who protect their sleep, move their bodies, and take proper breaks frequently outperform them in the actual exam.
Simple wellbeing practices for busy schedules
You don't need a complete lifestyle overhaul. Small, consistent habits make a real difference — and they don't have to eat into your revision time.
Sleep: the non-negotiable
Aim for eight to nine hours if you're in your teens. This isn't a luxury - it's when your brain does the work of turning today's revision into tomorrow's knowledge. A consistent sleep schedule (same time to bed, same time up) is more restorative than catching up at weekends.
If your mind won't switch off at night, try writing a short to-do list for tomorrow before you sleep. It signals to your brain that the day is done, and reduces the anxious circling of thoughts.
Movement: even a little counts
You don't need to be running marathons. A 20-minute walk, a short bike ride, even dancing in your room - anything that gets your heart rate up has measurable benefits for mood, focus, and memory. If you can get outside, even better. Natural light helps regulate your circadian rhythm, which directly affects sleep quality.
Some students find that physical activity helps them process stress and anxiety in a way that sitting with revision notes simply doesn't. If you're feeling overwhelmed, stepping away and moving can genuinely reset your thinking.
Breaks: not optional extras
Your brain isn't designed for continuous focus. After around 25 to 30 minutes of concentrated work, performance drops noticeably. Short breaks - five to ten minutes of proper rest, not scrolling through your phone - restore attention and improve the quality of your next study block.
Build breaks into your revision timetable deliberately. If they feel like a reward, you're more likely to resent them when you're stressed. If they're simply part of the plan, you'll use them well.
Food and hydration: the basics matter
A dehydrated brain works less efficiently. Keep water nearby when you're studying. Balanced meals - with protein, complex carbohydrates, and plenty of vegetables - sustain energy levels and concentration far better than sugary snacks, which cause spikes and crashes.
This doesn't have to be complicated. Eating reasonably well and drinking enough water is one of the lowest-effort, highest-impact things you can do during exam season.
Social connection: don't go it alone
Isolation during exam season is common and understandable - but it's rarely helpful. Brief, genuine connection with people you trust is genuinely good for your mental health and reduces stress hormones. A phone call with a friend, a meal with family, a short conversation that has nothing to do with exams - these aren't wasted time. They're maintenance.
Recognising when to step back
There's a difference between normal exam pressure and a level of stress that is genuinely harming you. It's worth knowing the signs.
Normal exam anxiety looks like: feeling nervous before a test, finding it hard to concentrate sometimes, worrying about results, feeling the pressure to perform. This is uncomfortable, but manageable.
It's worth taking notice if you experience: persistent difficulty sleeping even when exhausted, inability to eat or loss of appetite over several days, feeling unable to function or complete basic tasks, low mood that doesn't lift, or physical symptoms like frequent headaches or nausea. These signs suggest the pressure has moved beyond manageable, and it's important to talk to someone - a parent or carer, a trusted teacher, or a GP.
Stepping back doesn't mean giving up. It means recognising that you need to recalibrate in order to perform at your best. Some of the most successful exam results I've seen have come from students who took a day off when they needed it, rather than pushing through and burning out.
For parents/carers: modelling healthy boundaries
What your child sees you do matters, often more than what you say. If you're visibly stressed about their exams, working around the clock yourself, and treating rest as laziness, they will absorb that message.
Model rest as a value, not a failure. Take breaks yourself. Go to bed at a reasonable time. Talk about looking after yourself as something you actively choose, not something you do when you've "earned" it.
Watch your language around hard work. There's a meaningful difference between "working hard" and "never stopping." Praising effort and persistence is brilliant. Implying that rest equals weakness sends the wrong message at a critical time.
Create a home environment that supports sleep. This means keeping evenings reasonably calm, avoiding heated discussions about exams late at night, and being aware of how noise and light affect sleep quality.
Don't add to the pressure. Resist the urge to ask about revision constantly, compare your child to siblings or friends, or share your own exam anxiety. Your child is already carrying enough. Your job is to be the stable presence, not an additional source of stress.
Take wellbeing concerns seriously. If your child is struggling to sleep, not eating, or seems genuinely distressed rather than just nervous, don't dismiss it as "just exam stress." Acknowledge it, ask how you can help, and seek support early if things don't improve.
Celebrate the effort, regardless of outcome. Exams are important, but they are not the only measure of a person. Your unconditional support — the kind that isn't contingent on grades — is what your child will remember long after results day.
Ready to make real progress?
The students I've watched thrive during exam season aren't the ones who sacrifice everything else. They're the ones who show up consistently - for their revision and for themselves. They sleep. They move. They ask for help when they need it. And they perform.
You don't have to choose between looking after yourself and doing well. The evidence is clear: the two go together.
