Understanding Freshers’ Flu: Why It Hits Hard and Fast

It’s the start of a new term. You’ve managed to figure out the washing machine, your flatmates are becoming more like friends, and you’ve finally gotten through the chaotic freshers’ week. But just when you think things are settling down, BAM! You start feeling that scratchy throat, your nose begins to run, and suddenly, lectures seem more about controlling your cough than anything else.

You had heard the warnings, but the reality hit quicker than you expected. So what’s actually going on? Why do so many students experience freshers’ flu right at the beginning of term? And, I guess, why does it often seem worse than your typical cold?

“Freshers’ flu essentially consists of various common cold viruses that come together and hit us simultaneously,” explains Dr. Zania Stamataki from the University of Birmingham. It’s not the actual flu and, thankfully, it’s usually not serious. However, the influx of thousands of students brings a mix of respiratory viruses to campus.

With crowded lecture halls, shared kitchens that aren’t exactly spotless, and those late-night parties, it’s a perfect storm for illness to spread. Sheena Cruickshank, an immunologist at the University of Manchester, calls it a “mixing pot” of infections, noting that students from around the globe are coming together, often exposing themselves to viruses they’ve never encountered before.

Respiratory viruses evolve constantly. Sometimes, even slight variations can confuse your immune system, meaning it can fail to recognize them and you end up starting from scratch in the fight against them.

The Impact of Lifestyle Choices on Immunity

Your immune system serves as your body’s first line of defense against infections. It’s a complex network that helps identify and combat harmful invaders like viruses. But during freshers’ week, the immune system can be stretched thin and overworked. “Your diet, activity level, stress, and sleep—all these factors affect how well your immune system functions,” says Cruickshank, who recognizes that these aren’t likely top of mind for students adjusting to university life.

Stress, in particular, can be quite disruptive. The pressure to settle in, meet new friends, and juggle new responsibilities can feel so overwhelming. This stress triggers cortisol release, which unfortunately suppresses immune response. “You know those times when you’re under a mountain of deadlines and then, out of nowhere, you catch a cold?” she describes. Stress can also mess with your sleep, further weakening your immune system.

However, many students often feel that the need to socialize and fit in during freshers’ week takes precedence over resting.

“I didn’t want to miss out,” says Imogen Farmer, a 19-year-old second-year student at the University of Leeds. She recalls meeting friends every night during freshers’ week. “After that first week, I definitely dealt with typical symptoms like a sore throat and runny nose, and it lingered longer than I’d hoped.” Despite feeling under the weather, she feels it was worth it due to how much of the student experience revolves around socializing during these first weeks.

It isn’t just sleep deprivation that weakens your immune defenses. Many students tend to drink more alcohol, often as a way to soothe nerves, leading to reduced white blood cell production—essential for fighting infections. “People often think alcohol helps them sleep better, but it actually creates more stress and harms sleep quality,” notes Dr. Stamataki. Added to that, a poor diet can also compromise the immune system, especially if skipping meals becomes routine.

Contagion in Tight Spaces

With so many respiratory viruses circulating, you might find yourself in a lecture jammed between two classmates who are sneezing—each potentially carrying a different virus. And exposure happens easily, often before you’re even aware of it.

“There are times you might feel like you’ve dodged it, but you truly haven’t,” Dr. Stamataki cautions. “You might be feeling great, playing some sport, even hugging friends, but at the same time, you could be passing germs along.” The immune system in younger people may be strong, yet it’s somewhat limited as they haven’t encountered a wide array of viruses before. While first encounters with illnesses can be rough, subsequent exposures tend to be milder.

You could also end up with two infections simultaneously, creating a tricky situation. Your immune system might be overwhelmed one moment or, alternatively, kick into high gear, working overtime to fend off multiple invaders. If you’re unlucky enough to catch a second infection shortly after recovering from the first, it’s often because you’re already run down, which can lead to complications.

If you notice symptoms that persist longer than expected or seem to worsen after initially improving, it might be wise to seek medical advice. “If you see spots in your throat, that could indicate strep throat and you might need antibiotics,” she warns. Remember that antibiotics are ineffective against viral infections like the common cold or flu.

When to Seek Help

Although many viruses are mild, some can pose serious risks, and meningitis is certainly one to be wary of. It can resemble freshers’ flu closely at first but, if untreated, can lead to severe complications like seizures or brain damage.

Vaccinations are typically administered to protect against several types of meningitis during childhood, yet it’s essential to remain alert for symptoms—even if vaccinated. So what should you specifically watch for?

• High temperature or fever
• Nausea
• Headache
• A rash that doesn’t fade under pressure (although not everyone develops one)
• Stiffness in the neck
• Discomfort under bright lights
• Drowsiness or lack of responsiveness
• Seizures

Meningitis spreads similarly to colds—through close contact. As it inflames the membranes surrounding the brain and spinal cord, it’s critical to act fast if you experience these symptoms; calling emergency services or heading to A&E is vital.

For many students, there’s often an unspoken pressure to keep pushing through even when feeling unwell. “You’re driven to keep going because that’s what’s expected,” suggests Emily Valentine, a fellow student at the University of Leeds. While she tends to take a break when ill, many of her peers push on to attend lectures, particularly at the start of the term.

Recorded lectures, a shift that arose from the pandemic, might have made catching up a bit easier, but experts still advocate for listening to your body. “It can take some time for your body to recover from a significant viral assault,” reminds Prof. Cruickshank.
