With spring and summer travel season approaching, infectious disease specialists are sharing their top strategies for staying healthy during flights. Studies show airplane cabins can be breeding grounds for respiratory viruses, but these evidence-based precautions can dramatically reduce your risk.
8 Doctor-Recommended Strategies
- Choose a window seat: Research from Emory University found window seat passengers have 80% fewer interactions with potentially sick travelers moving through the aisle
- Use the overhead air vent: The filtered air creates a cone of protection around your seat, pushing airborne particles away from your breathing zone
- Wipe down surfaces: Tray tables harbor more bacteria than toilet seats according to a 2025 Auburn University study. Use disinfecting wipes on tray tables, armrests, and seatbelt buckles
- Stay hydrated: Cabin humidity drops to 10-20%, drying out mucous membranes that serve as your first defense against pathogens. Drink at least 8 ounces of water per hour of flight
- Avoid touching your face: The average person touches their face 23 times per hour. Be conscious of this habit during flights
- Skip alcohol before and during flights: Alcohol suppresses immune function and worsens dehydration at altitude
- Use saline nasal spray: Keeps nasal passages moist and functional as germ barriers
- Time your meals: Eating before boarding reduces the need to lower your mask or touch shared surfaces during food service
When to Wear a Mask
Dr. Angela Martinez from Johns Hopkins recommends wearing a high-quality N95 or KN95 mask on flights longer than three hours, especially during peak cold and flu season or when traveling with immunocompromised family members.
Following these simple strategies can make the difference between arriving at your destination healthy and spending the first few days of vacation in bed with a cold.
