News Editor Jana Bazeed discusses the best student hacks for optimising caffeinated 9am lectures.
Let’s be honest: if you’ve made it to a 9am lecture in the first week of uni, you’re already doing better than most of us did. The next challenge? Staying awake.
Enter caffeine, humanity’s favourite socially acceptable psychoactive drug, and the closest thing to legal sorcery you’ll find in a campus café.
How does it work?
Your brain naturally produces adenosine throughout the day – a chemical that builds up and makes you feel tired. Caffeine slots neatly into the same receptors that adenosine uses, blocking that ‘you’re exhausted’ signal and letting your neurons keep firing. The problem is, the adenosine doesn’t just disappear; once the caffeine wears off, you get hit with all the fatigue you’ve been ignoring. That’s the dreaded ‘crash.’
There’s a catch though.
Over time, you can begin to develop a tolerance. If you’re downing flat whites on the daily, your brain starts making more adenosine receptors to compensate. That means you need more caffeine to get the same buzz.
Not all caffeine sources are created equal.
A standard cup of coffee has around 96mg of caffeine (depending on the bean, brew, and whether the barista likes you). Black tea sits at about 48mg, but also delivers L-theanine, an amino acid that smooths the caffeine jitters. Energy drinks can have anywhere from 80 to over 200mg. They hit fast, but the spike-and-crash cycle can be brutal, especially if you’ve skipped breakfast. An empty stomach speeds up absorption into your bloodstream, causing a sharper, more intense spike in its effects. And then there’s matcha: a powdered green tea, now a student classic. It’s got roughly 70mg of caffeine per serving, the same calming L-theanine as regular tea, arguably giving you the best of both worlds.
How to survive your first term without becoming a jittery, sleep-deprived cryptid.
- Time it right: Caffeine takes about 15 to 45 minutes to kick in and lasts four to six hours. Avoid it within six hours of bedtime unless you enjoy lying awake wondering if you’ve remembered to submit your coursework.
- Cycle your intake: Give your receptors a break by having a caffeine-light day once in a while.
- Hydrate: Coffee is mildly diuretic (which is why you’ll find that you need more frequent trips to the bathroom), and dehydration is never a good look.
So no, caffeine isn’t evil. It’s a tool. Use it wisely, and it’ll get you through even the most soul-draining morning seminar. Abuse it, and you’ll be Googling “Can you die from too much Monster?” at 3am.
