Experts say keeping outlets open can help you avoid contact with certain germs and viruses and cut your risk of getting sick in half, especially during cold and flu season, because flights in this case can be a focus for the transmission of infections.
“If there is a virus particle in your periphery, in theory, it could be pushed and quickly transported out of the space around you,” says Dr. Marc Gendreau, a specialist in infectious diseases linked to air travel.
Airplane ventilation systems alone filter the vast majority of airborne particles.
The onboard ventilation system is actually equal to or slightly better than that of most operating rooms and hospitals around the world.
Congestion in the aisles after landing can be a great danger, because after landing the pilot shuts down the aircraft’s ventilation system before the crew operates the auxiliary power unit in the aircraft.
Additionally, drinking too many caffeinated beverages can lead to dehydration. Because immune cells need water to flush out toxins and wastes, lack of water makes them vulnerable.
It is recommended that you bring hand sanitizer on board, as well as wash your hands to reduce risk.
