Even the healthiest habits utilized daily can fail at protecting you in crowded locations like airports and planes. There are additional precautions that you can take between the time you arrive at the airport and your intended destination to reduce the chance of contracting illnesses from fellow travelers.

Allow the packet to dry out some before adding the alcohol. Do not add a large amount, as you do not want an excessive amount of liquid that might leak. Also, mark the container, so it never gets used as it was initially intended. Using these wipes before and after bathroom use can significantly diminish the number of bacteria that make it from your hands to your face.

Before boarding, security requirements entail searching passengers and their belongings, including shoes. The area can pose hazards to your feet, from tiny microbes that cause intense itching to slivers of glass that come loose from dirty boots.

Similarly, changing into a fresh pair before you put your shoes back on can protect your feet from foreign substances that the first pair of socks might have collected.
