"Reader Question: Someone told me that you should put Vaseline in your nose before getting on a plane to avoid catching a cold. Is this true? I wish it were that simple. Vaseline will not kill bacteria or viruses, but it can help keep your nasal passages moist. Airplane air can be drying, and if the inside of your nose becomes cracked and dry, infection is much more likely. However, your best bet for staying well is to have tissues and alcohol-based hand gel with you in your carry-on bag. Be sure to use the hand gel before you eat and drink plenty of water to stay hydrated to keep your body&amp;#039;s defenses up!
