Your hands pick up the most germs that can lead to colds and other illnesses.
This could be from a hand shake or touching an arm rest, just touching a door handle could lead to a full-blown cold or worse in days.
Germs can survive for hours on skin as well as objects all around you. The good news itâ€™s as simple as washing your hands with soap from a soap dispenser and drying with a hand dryer to stop the transfer of harmful germs.
Traveling in a plane involves being situated in a cramped environment, often for a number of hours and it is not always possible to get out of your seat and down the aisle before every snack for hand washing. Tray tables may block aisles before meals are served, and your neighbours are unlikely to want you getting up and down throughout the flight.
