Chances are you'll experience Freshers' Flu at least once while you're at University. Symptoms include a sore throat, high temperature, shivering, sneezing, dry cough and a bad headache. Freshers' Flu isn't actually a form of Flu at all; it's more like a bad cold. As some of the symptoms are also sthe same as those of Coronavirus, it's advisable to have a Coronavirus test, just to be sure. Details about how to get a test can be found on the NHS Coronavirus webpage.
Nobody knows exactly what causes Freshers' Flu, but it's generally thought to be down to a range of factors including meeting lots of new people at University, coupled with a lack of sleep, a junk food diet, alcohol and stress. Eating healthily (including vitamins), drinking lots of water, getting enough sleep and generally taking care of yourself, will help you to feel better.
