Places with lots of people like airports and bus stations are just part of travel. Picking up germs doesn’t have to be. Wash your hands a lot. Here some advice from my acupuncturist. Decrease your risk of airborne bugs by swabbing inside your nose with a Q-tip tipped with antibiotic cream before entering a highly populated area or a plane with recycling air. Repeat a few times per trip. Also, decrease your risk of increased blood pressure or blood clots by lowering your sodium intake while traveling on planes. Avoid salty snacks and bring your own (fresh and dried fruit, raw or toasted nuts and seeds, little tomatoes, radishes, veggie sticks). Another way to decrease stress and viral risk is to avoid sugar which has been associated with decreased immune system function.
