Wash your hands. Studies have shown that simple hand washing can help prevent a large number of illnesses. So wash your hands, especially any time you'll be touching your nose, mouth or eyes or if you've been around others who are sick.
Avoid sharing beverages. Germs are easily spread through the sharing of drinks, alcoholic or otherwise, so get your own and avoid sharing with friends.
Don't go to class. If you're sick, don't force yourself to go to class. It will only make you feel worse and infect other students. Email your professors that you're ill and stay home and rest.
Get to the doctor. If you have symptoms that aren't showing any signs of clearing up within a few days, you may need to take a trip to the campus clinic or your doctor. Simple illnesses can mutate into much more deadly and dangerous ones if left alone so make sure to seek help if you aren't feeling any better.
Drink lots of fluids. Colds and flu can wreck havoc on your body, often depriving it of much needed fluids. Replenish these by drinking plenty of water or energy drinks when you're ill.
Get a flu shot. With so many germs around, sometimes getting a flu shot is the best thing you can do to avoid getting sick. Many colleges offer these for reduced prices so students can get vaccinated for little out of pocket expense.
Avoid ill friends. If your friend is sick, try to avoid spending too much time around them. While bringing soup or medications won't hurt, touching ill friends and their stuff can increase your chances of getting sick yourself.
Don't touch your eyes, nose or mouth. If your hands aren't totally clean, try to avoid touching these areas. The membranes in these areas make it easy for bacteria and viruses to enter your body.
Try simple over the counter remedies. Most viruses leave you feeling miserable but with no recourse in medications that can make them go away. Try out over the counter remedies to help ease your symptoms.
Keep immunizations up to date. While most students will have been immunized as a child, some shots may need to be updated when you enter college. Make sure yours are up to date to keep you from contracting a serious illness.
