Two things have to happen for you to get sick with a cold or the flu. You have to be exposed to the virus that causes the cold or flu, and your immune system has to fail to fight off the illness. Therefore, to avoid getting sick from a cold or the flu, you should both avoid becoming exposed to these germs, and also fortify your immune system.
To avoid getting sick during cold and flu season, it is best if you wash your hands frequently. It’s almost impossible to never touch anything that might have germs on it. Doorknobs, sinks, railings, and computer keyboards are all popular hiding places for germs. What you can do is to wash your hands after encountering any item that might have germs on it. You should wash your hands before your touch your face, especially your eyes or mouth.
Boost your immune system by eating healthy. Eat plenty of fresh vegetables, fresh fruits, and a healthy amount of protein and carbohydrates. Your body uses the nutrients in food to function. If you are lacking in vitamins and minerals, your immune system will be weakened. Getting a healthy amount of sleep is very important for immune system function. Adults should get at least eight hours of sleep each night. You should also dress warmly in cold weather. If you are cold, tired, malnourished, or otherwise in discomfort, it puts stress on your immune system. Any stress on your immune system could result in an inability to fight off the germs that cause colds and the flu.
