Holiday travel increases the risk of illness as crowded airports and winter flu season combine to threaten passenger health, according to UT Southwestern Medical Center.
Travelers face heightened exposure to germs and stress during the busiest days of the year, which can lead to post-travel colds, fatigue, or digestive issues. Understanding these specific risks allows for better preparation, according to Katherine Liang, M.D., Assistant Professor of Family and Community Medicine at UT Southwestern Medical Center.
“Travel introduces health risks we may not encounter at home,” Liang told News-Medical. “Understanding those risks and preparing ahead of time can help prevent a health issue from disrupting an otherwise great trip.”
Prevent Dehydration and Infection During Flights
Recycled cabin air is significantly drier than ground-level air, which strips moisture from the eyes, mouth, and skin. Experts recommend drinking water before and during flights rather than consuming alcohol, coffee, or soft drinks. Travelers should also pack electrolyte packets, nasal spray, and eye drops in carry-on bags to combat dehydration.
High-touch areas such as kiosk screens, armrests, and charging stations serve as magnets for bacteria and viruses. Frequent use of hand sanitizer and handwashing remain the most effective ways to reduce infection risks in transit, according to UT Southwestern.
Protecting Against Blood Clots
Sitting in a confined space for longer than four hours increases the risk of deep vein thrombosis, where blood clots form in the legs. These clots can potentially travel to the lungs, causing a pulmonary embolism. Moving around at rest stops or walking the aircraft aisle during cruise altitude helps maintain circulation.
For those with a history of blood clots, pregnancy, or recent surgery, compression socks—also known as anti-embolism stockings—can prevent blood from pooling. These garments are available through pharmacies and retail stores for those at elevated risk.
Managing Respiratory Health and Medications
Flu season typically peaks between fall and the new year as colder weather drives travelers into crowded indoor spaces. Wearing a well-fitting mask provides a layer of protection against RSV, COVID-19, and influenza, particularly for immunocompromised or older passengers.
Travelers should keep all essential medications in a carry-on bag to avoid interruptions caused by lost luggage or flight delays. Passengers using medical devices like CPAP machines should confirm specific airline policies before arriving at the airport.
Nutritional Planning and Sleep Hygiene
Nutritious, TSA-approved snacks such as nuts, jerky, and fruit help prevent the lightheadedness or nausea associated with traveling on an empty stomach. Packing healthy options is especially important for travelers with dietary allergies, as airport food choices are often limited.
Quality sleep is vital for immune system function and stress management. Using an eye mask, earplugs, or a travel pillow can help mitigate the effects of hotel noise or jet lag. If travel anxiety occurs, mindfulness exercises like box breathing or the 5-4-3-2-1 sensory technique can help ground the traveler.
Stay Current on Seasonal Vaccinations
Staying current on seasonal vaccinations is a primary defense against holiday respiratory illnesses. Travelers should consult their healthcare provider regarding which immunizations are appropriate for their specific health status.
“Holiday travel should be about spending time with the people you care about,” Liang said. “You can’t eliminate every travel-associated health risk, but simple precautions before and during your trip can help you stay healthy and make the most of your holiday season.”
Commonly Asked Travel Health Questions
How can I identify if I am at risk for blood clots during a flight?
Individuals who have recently undergone surgery, experienced a traumatic injury, are pregnant, or have a personal history of blood clots are at higher risk. Medical professionals recommend these travelers consider compression socks to enhance circulation.
What specific breathing exercises help with travel stress?
The 5-4-3-2-1 technique is a common mindfulness exercise used to manage anxiety. It involves naming five things you see, four you can touch, three you can hear, two you can smell, and one you can taste.
