You don’t wash your hands frequently
Because viruses and bacteria can linger everywhere, you have to be vigilant about keeping your hands clean, warns Dr. Ewing. Washing your hands frequently with soap and water is the best technique, but if washing facilities are not available, a hand sanitizer like Purell can work. Just make sure you aren’t committing any of these common hand-washing mistakes.
You fail to take caution while traveling
Airplanes and hotels challenge your immunity because you’re exposed to more pollutants and infectious organisms. Bring sanitizing wipes to clean tray tables, seats, and armrests on airplanes. According to an article in Conde Nast Traveler, the remote control, desk, and phone in hotel rooms can expose you to germs. The article recommends alcohol wipes for these surfaces and regular hand washing to help reduce your risk of getting sick. And try these 10 habits doctors use to avoid the cold and flu.
You overuse antibiotics
Say it with us: Antibiotics are for bacteria, and they won’t work against colds or flu. “Taking antibiotics when not needed can negatively affect the immune system,” says Dr. Ewing. When antibiotics destroy good bacteria, they can leave your immunity compromised. “Research has shown that individuals who take antibiotics for chronic infections are at a greater risk for a weakened immune system.”
