🍌 Eat a banana before your driving test. No, seriously, there's science behind this.
Before you scroll past, hear me out. This isn't a joke. It's actually one of the most useful pieces of advice I give to nervous test candidates.
Here's the science 👇
🧠 POTASSIUM, THE STRESS BUSTER
Bananas are packed with potassium. When you're anxious, your body releases cortisol, and your blood pressure rises. Potassium helps regulate blood pressure and supports your nervous system, quite literally helping to take the edge off that test-day panic.
⚡ NATURAL ENERGY, NO CRASH
A banana gives you a steady release of natural sugars (glucose, fructose and sucrose) along with fibre, which means your brain gets a sustained energy boost without the spike-and-crash you'd get from caffeine or energy drinks. You want consistent, focused energy for 40 minutes, not a jittery buzz followed by a slump.
😌 TRYPTOPHAN, THE MOOD LIFTER
Bananas contain tryptophan, which your body converts into serotonin, the "feel good" neurotransmitter. More serotonin = calmer mood = clearer thinking = better driving.
🍽️ EAT IT 30–60 MINUTES BEFORE
Give it time to work. Don't eat a massive meal (that redirects blood flow to your stomach), don't load up on coffee, and definitely don't skip food altogether, low blood sugar will tank your concentration.
The full test-day ritual I recommend:
✅ Good night's sleep the night before
✅ Light breakfast, nothing too heavy
✅ Banana 30–60 mins before your test
✅ Water, not energy drinks
✅ Arrive early, last-minute rushing spikes cortisol
✅ Remember: your instructor believed you were ready. Trust that.
Share this with someone who has a test coming up, it might just make the difference! 🍌
