You’re up to your eyes in revision schedules and practice papers. So it’s little wonder we often forget a crucial element that underpins success in exams: nutrition and self-care.
Nutrition and self-care are the fuel that powers your brain and overall well-being during this demanding time. Ignoring it is like trying to run a car on empty – it simply won’t perform at its best.
Nourishing your teen with the right foods and encouraging small moments of self-care can make a significant difference in their ability to focus, retain information, and manage stress. Let’s explore some practical and manageable ways to weave good nutrition and well-being into your exam period routine.
Nutrition for Performance ​
- Fuel for the Task at Hand: It is important to tailor nutrition to the activity or task, whether it’s a physical activity or an exam. ​​ For exams, this means avoiding high-energy foods like chocolate, white rice, or white pasta, which cause blood sugar spikes followed by crashes. ​ Instead, focus on slow-release foods that provide sustained energy throughout the day. ​
- Balanced Diet: A balanced plate is essential, comprising whole-grain carbohydrates, proteins, fats, and colourful vegetables rich in vitamins and minerals. ​ These nutrients support bodily functions, brain health, and overall performance. ​ Omega-3 fatty acids from oily fish are particularly beneficial for brain cell growth and connectivity, while antioxidants from foods like blueberries and dark green vegetables help reduce stress and inflammation. ​
- Hydration: Staying hydrated is critical for cognitive function. Even a 2% loss in body weight due to dehydration can impair thinking and processing abilities. ​ While water is ideal, no-added-sugar squash or tea can also be consumed. ​ However, overhydration should be avoided, as it can lead to imbalances. ​ Adding mineral salts to water can help maintain hydration levels. ​
- Caffeine: We often associate coffee with urgent study tasks. And caffeine can aid alertness and cognition, but should be consumed in moderation. ​ Its half-life is approximately four hours, so consuming caffeine late in the evening can disrupt sleep. Avoid caffeine after 8 PM to allow natural sleep hormones to take effect.
Sleep and Recovery
- Importance of Sleep: Sleep is paramount for consolidating learning and maintaining cognitive function. ​ REM sleep, in particular, helps lock in long-term memories. ​ Less than seven hours of sleep is considered sleep deprivation, which can negatively impact performance. ​ Sleep hygiene is so important, such as preparing for bed before feeling tired and minimising blue screen exposure. ​
- Avoiding Late-Night Cramming: Instead of staying up late to cram, create a revision plan and stick to it. This will also help reduce feelings of anxiety, keeping your teen calm and relaxed in the evening, rather than up all night worrying. ​ Sleep allows the brain to process and retain information, making it more effective than cramming. ​
Physical Activity
- Benefits of Exercise: Physical activity, even a brisk 20-minute walk, can reduce stress hormones, boost mood, and improve brain function. ​ Exercise promotes cell growth, including brain cells, and helps maintain overall health. ​ This is especially important if your teen gets stuck in a rut, or notices their performance dip. Step away from studying to go for a walk.​
- Incorporating Outdoors into Revision Plans: Being outside in fresh air and sunlight can be integrated into a revision schedule to enhance focus and confidence. Do not underestimate the power of being in nature to help feel calm and also reinvigorated.
Practical Tips for Busy Schedules
- Meal Preparation: Planning a menu for the week helps to avoid in the moment poor choices. But healthy doesn’t have to mean time. For those with limited time, use a slow cooker to prepare balanced meals. ​ This method allows for easy, nutritious meals without the hassle of cooking after a long day. ​
- Family Involvement: For those teens who tend resist healthier fare, get them involved with meal preparation. It’s a valuable learning experience and can make the food more palatable (if you’ll excuse the pun!).
Key Takeaway: Balance ​
The overarching theme is balance—balancing nutrition, hydration, sleep, and physical activity to optimise performance. ​ A healthy lifestyle is not about quick fixes but about consistent, thoughtful choices that support both physical and mental well-being.
This holistic approach to health and nutrition applies not only to athletes but also to students preparing for exams, ensuring they perform at their best during stressful periods. ​
