Did you know sniffling, sneezing and coughing can be sign of a cold or allergies? Both can make you feel miserable, but only one comes with a fever, body aches or a sore throat. Knowing which one you have can help you know whether you should call in sick.
To help avoid catching a cold, make sure you wash your hands regularly or use a hand sanitizer. You can keep your immune system strong by exercising regularly, eating a healthy diet and getting plenty of sleep.
Some studies have shown a small benefit from vitamin C. Other supplements such as vitamin E, Echinacea or zinc do not have strong enough evidence to recommend their use for prevention of upper respiratory infections.
