?Summer has been replaced by the sounds of fall - the wind rustling through the changing leaves, the cheers at football games, and the coughing and sneezing of congestion, colds and flus. When the weather turns colder, cold and flu viruses take advantage of weakening immune systems everywhere. Studies show that the average person contracts about three colds a year, with those who are in regular contact with children having an increased risk. Because the common cold and influenza are viruses, antibiotics do not help, and there is no cure. You can get a flu vaccination nearly anywhere, but the best strategy remains prevention. With the worldwide emergence of the H1N1 virus, it is absolutely critical that you protect yourself and your family from one of the most highly-feared flu seasons in nearly a century. Wash Your Hands One of the simplest and most effective ways to keep from catching a cold or flu virus is through frequent hand washing. Antibacterial hand sanitizers give you a viable substitute for soap and water. Alcohol-based foams and gels are also recommended by the Centers for Disease Control for hand hygiene. Eat Healthy Nutritious food is absolutely essential to building and maintaining a healthy immune system. A well-balanced diet of fruits and vegetables will provide energy and nutrition for optimal growth and development. Taking a daily multi-vitamin will also ensure you are receiving an adequate dose of vitamins. Sleep Lack of sleep lowers your immune system's ability to react quickly and efficiently, making you susceptible to viruses. It is recommended, especially in deep winter, to get seven to eight hours of sleep every night. Clean Air Since viruses can be transmitted through the air by coughs and sneezes, it's a good idea to keep the inside spaces you occupy on a daily basis clean. This includes the air you breathe. A quality air purifier in your home, bedroom, and office is recommended to keep the air you breathe clean. The Vornado?
