(What business travelers and families should know)
Airports are crowded, flights are full, and seasonal illness is circulating. What’s often overlooked especially in Australia’s hot, dry climate is the role your nose plays as the body’s first line of defence against airborne irritants and pathogens.
The nasal passages are designed to filter, humidify, and regulate the air we breathe. But heat, air-conditioning, dehydration, and long-haul flights can dry out the nasal lining, reducing its ability to trap viruses and particles effectively. For Australians travelling to colder hemispheres, the sudden shift to cold, dry winter air can further stress this natural barrier.
Whether you’re flying for work, taking a summer break, or heading overseas into winter, supporting nasal health can make a meaningful difference.
Before you fly:
• Stay well hydrated, particularly in hot weather and air-conditioned environments
• Use a gentle saline spray to support nasal moisture before boarding
• Apply a light nasal moisturiser to protect the delicate skin and lining of the nose
During the flight:
• Limit caffeine and alcohol, which can contribute to dehydration
• Consider wearing a mask in crowded cabins or terminals if you’re prone to sinus or nasal issues
After arrival:
• Rinse the nasal passages to help clear irritants, pollutants, and microbes
• In colder or heated indoor environments, support humidity where possible to reduce ongoing dryness
This isn’t just about comfort, it's about maintaining the nose’s ability to protect the respiratory system.
The “post-travel cold” doesn’t have to be inevitable.
Healthy travel habits can start with something simple: looking after how you breathe.
