CATCH 22 % - INSTEAD OF CATCHING A COLD OR WORSE......

In these challenging times and in light of efforts to improve confidence in air travel, we recognize increased focus on air quality, including dry air and how it impacts our susceptibility to viruses. The main benefit with higher humidity is reduced risk to contract an infectious decease as it prevents dry air related degeneration of the immune system.

During a long-haul flight, dry cabin air gradually dehydrates the Mucous membrane which increases human susceptibility to bacteria and viruses. The Mucous membrane is part of our first line of defense, as it contains antibodies that physically catches pathogenies for transport and destruction. It is also higher probability that the clearance system slows down in a very dry climate. Bottom-line is that a weakened immune system not only increases risks during flight but also, perhaps more importantly, upon arrival at destination.

Humidifiers generate a striking increase in air humidity from extremely low levels – between 5 – 10 % RH in a Business Class cabin. Humidifiers are required to prevent that an aircraft cabin climate becomes far more dehydrative than any place on Earth. Without active humidification, the humidity falls short of the required (evolutionary) level for humans to feel and function well.

Another drawback with dry air is how it changes virus droplets to shrink in size as they lose their moisture content through evaporation. Smaller droplets remain airborne longer and increases the overall time they can float around. Doubtlessly, the infectious decease risk in aircraft via droplets is effectively mitigated by the efficient air ventilation system. A humidifier is another supportive measure that further reduces droplet risks.
