Ugh. The dreaded flu. Influenza (the scientific name for the flu) is an upper respiratory infection that can result in symptoms like a dry cough, sore throat, fever, chills, nausea, vomiting and loss of appetite. And because it's spread by airborne virus cells, it's highly contagious.
Although bed rest and fluids are typically recommended for treating the flu, wouldn't you much rather prevent yourself from getting the flu altogether? Boosting your immune system may help your body ward off the influenza virus, preventing you from contracting influenza (hallelujah!). And if you already have the flu, most of these tips can help you start to feel better quickly.
