Preparing for the flu season Published Sept. 24, 2014 By Airman 1st Class Luke J. Kitterman 52nd Fighter Wing Public Affairs SPANGDAHLEM AIR BASE, Germany -- Just because the leaves start to fall doesn't mean service members and their families should allow their immune systems to do the same. A weak immune system can cause serious health problems especially with flu season coming. The chances of a person getting influenza, also known as "the flu," can be greatly decreased by knowing and performing simple yet effective health practices every day. "Most flu viruses are spread by direct contact," said U.S. Air Force Staff Sgt. Misty Warner, 52nd Aerospace Medical Squadron communicable disease program NCO in charge. "Methods of prevention include washing your hands with soap and warm water, avoiding close contact with sick people and most importantly, getting an annual flu vaccine." According to the Centers for Disease Control, the vaccine protects against up to four viruses research suggests will be the most common. Everyone aged six months and older is highly recommended to get the flu vaccine every year. The vaccine is mandatory for active duty. In addition to the vaccine, exercise is a positive factor when preventing the flu, said Emily Posadas, Health and Wellness Center health promotion coordinator. "Exercise helps to increase the body's immune cells, which in turn, help to fight infections, like the flu," Posada said. "Each time we go for a walk, run or go cycling, we help to boost our body's immunity. Thirty minutes of aerobic exercise per day is enough to help ward off the flu during flu season." For smokers, substituting the nicotine habit for exercise is one of the best changes a person can make Posada said. "Smokers, on average, get more frequent colds that last longer and are more severe than those of non-smokers," Posada said. "Not only does regular smoking affect a person's immune system, but being around second hand smoke can also affect it as well." According to Warner, symptoms of the flu include fevers, chills, cough, sore throat, runny nose, muscle aches, headaches, fatigue, and sometimes vomiting and diarrhea. Staying home while having these symptoms not only betters you chances of getting better but prevents the spread of infection. Practicing these healthy habits can be the difference between staying in bed sick this season and out enjoying activities.
