8 Nutrition and Lifestyle Tips to Help Teens Stay Focused During Exams

Exam season can be tough on teens — and just as demanding for parents. With the pressure to revise, perform, and stay motivated, it’s no wonder their energy, mood, and sleep can take a hit. But the good news is that small, consistent changes in their daily routine — especially around food and lifestyle — can make a huge difference to their focus and resilience.

Here are 8 gentle and practical ways to support your teen nutritionally and emotionally during exam time:

1. Start Strong: Prioritise Protein at Breakfast

A good day starts with a good breakfast — and protein is key. Ditch the toast or sugary cereal and try something more sustaining like:

• Scrambled eggs on rye or oatcakes

• Chia pudding with full-fat milk or coconut milk

• A smoothie made with kefir, protein powder, berries, and nut butter

• Nut butter on oatcakes with a side of fruit

Why it works: A protein-rich breakfast helps stabilise blood sugar, supports clearer thinking, and reduces the risk of mid-morning energy crashes.

2. Smart Snacking: Swap Sugary Snacks for Protein-Based Treats

Sweet cravings are common when stress hits, but snacks can still feel like a treat without the sugar spike. Try:

• Bliss balls made with tahini and dates

• Full-fat Greek yoghurt with berries and seeds

• Homemade gummies using gelatine and juice

• A warm mug of cacao with whole milk and collagen powder

Tip: Collagen or gelatine powders can be added to smoothies, soups, and stews for an easy protein boost — no complaints, we promise!

3. Friendly Fats and Gut-Loving Ferments

Healthy fats are essential for brain function, hormone balance, and mood. Include more of these in meals:

• Oily fish like salmon or mackerel

• Avocados, nuts, seeds, and olive oil

• Real butter or ghee

• Full-fat kefir to support gut health and immunity

Don’t fear the fat — it helps fuel the brain and keeps your teen feeling satisfied for longer.

4. Balance Blood Sugar: Reduce Sugar Without the Struggle

Rather than going cold turkey on sugar (which can backfire), try a 'crowd it out' approach. Offer protein- and fat-rich foods before sweet ones to naturally reduce cravings.

When blood sugar is balanced, you’ll notice fewer crashes, better moods, and more consistent focus — a win for everyone in the household.

5. Hydration for Teen Exam Nutrition and Mental Clarity

Did you know even mild dehydration can impair concentration and memory? Encourage your teen to:

• Keep a reusable water bottle on their desk

• Sip herbal teas like peppermint or rooibos

• Add berries, cucumber or citrus slices for flavour

Limit sugary drinks and energy drinks, which can lead to focus-destroying blood sugar spikes.

6. Let There Be Light (Especially in the Morning)

Getting outside first thing in the morning helps reset your teen’s body clock and supports mood and sleep.

Aim for:

• 10–15 minutes of natural daylight within an hour of waking

• Bare skin and no sunglasses if possible, for better light absorption

Bonus: fresh air and grounding (barefoot if they’re game!) can help regulate stress levels and promote a sense of calm.

7. No Screens Before Bed = Better Sleep

Screen time before bed is a major sleep disruptor. Encourage a calming bedtime routine by:

• Turning off screens at least an hour before bed

• Dimming lights or switching to red/amber lighting

• Encouraging calming activities like reading, journaling, or listening to music

Good sleep is a superpower when it comes to memory and focus — and it’s often the missing piece during exam time.

8. And Don’t Forget... You Matter Too

This season can be emotionally intense for parents as well. Supporting a stressed teen while managing your own responsibilities is no small feat.

So please remember:

• Your calm presence is more valuable than a perfect meal plan

• Prioritising your own nutrient-rich meals, fresh air, and rest helps the whole family

• Your steadiness helps model resilience — and that’s what they need most

Final Thoughts: Nourish Their Focus, Support Their Resilience

Exam season doesn’t have to mean burnout for your teen — or for you. With just a few shifts in nutrition, routine, and emotional support, you can help them feel more focused, calm, and prepared.
