8 Doctor-Recommended Ways to Stay Germ-Free While Flying

Air travel has become an essential part of modern life, but with it comes the unavoidable challenge of being in close proximity to others in a confined space. For many, the thought of being in an airplane's germ-laden environment is daunting, especially during flu season or in the wake of global pandemics like COVID-19. Understanding how to protect yourself from germs while flying can make the difference between staying healthy and coming home with an unwanted illness. Here are eight strategies to help you avoid germs on an airplane when you have to fly.

1. Choose Your Seat Wisely

Where you sit on the plane can significantly impact your exposure to germs. Studies have shown that passengers seated in the aisle seats are more likely to come into contact with potentially contaminated surfaces and other passengers moving up and down the aisle. Opt for a window seat if possible, which reduces your interaction with other passengers and minimizes exposure to high-traffic areas. In addition to being farther from the aisle, the window seat allows you to control your immediate environment better, lowering the chances of encountering airborne pathogens from people walking by.

2. Disinfect Your Space

Airplanes are notorious for their quick turnaround times between flights, often leaving cleaning crews with limited time to thoroughly sanitize each area. As a result, many surfaces you encounter on a plane might not be as clean as you’d hope. Bring disinfectant wipes with you and clean high-touch areas like tray tables, seatbelt buckles, armrests, and the in-flight entertainment system. Remember to also wipe down the window shade if you're seated by the window. While it may seem excessive, these simple actions can significantly reduce your risk of coming into contact with harmful bacteria and viruses.

3. Practice Good Hand Hygiene

Your hands are one of the main ways germs enter your body, especially when you touch your face after contacting contaminated surfaces. Hand sanitizer with at least 60% alcohol content is a must-have when flying. Use it after touching any surfaces, such as door handles, overhead bins, or even your seatbelt. However, hand sanitizer is not a substitute for washing hands with soap and water. Whenever possible, wash your hands thoroughly in the restroom, ensuring you scrub for at least 20 seconds. Avoid touching your face, especially your eyes, nose, and mouth, as much as possible to prevent the transfer of germs.

4. Wear a Mask

Face masks have become synonymous with germ prevention, especially during the COVID-19 pandemic. Masks are not only useful for protecting others if you're sick, but they also reduce your exposure to respiratory droplets from other passengers. Choose a well-fitted mask that covers your nose and mouth completely, and wear it for the duration of your flight. For added protection, consider a mask with multiple layers or a medical-grade mask such as an N95 or KN95. Remember to replace disposable masks after each use and wash reusable ones regularly to maintain their effectiveness.

5. Stay Hydrated and Boost Your Immune System

Flying can be dehydrating due to the low humidity levels in airplane cabins. Dehydration can weaken your immune system, making you more susceptible to infections. Drink plenty of water before and during your flight to stay hydrated. Additionally, consider boosting your immune system in the days leading up to your trip by eating a balanced diet rich in vitamins and minerals, particularly vitamin C and zinc, which are known for their immune-boosting properties. Bringing healthy snacks on board, such as fruits and nuts, can also help maintain your energy levels and overall well-being during the flight.

6. Use Airplane Ventilation Systems to Your Advantage

Many passengers worry about the air quality on planes, but modern aircraft are equipped with sophisticated air filtration systems. Most commercial airplanes use HEPA (High-Efficiency Particulate Air) filters, which are effective at capturing airborne particles, including bacteria and viruses. To maximize the benefits of these systems, keep your overhead air vent open and direct the airflow slightly in front of your face. This can help create a barrier of filtered air that may push away airborne particles from your immediate space. However, while these systems are helpful, they are not foolproof, so combining this strategy with other precautions is essential.

7. Minimize Movement Around the Cabin

The more you move around the cabin, the more you expose yourself to potential germs. Try to limit your movement by bringing everything you need with you to your seat, including snacks, water, and entertainment. Use the restroom before boarding the plane to minimize the need to use the airplane restroom, which is a high-touch area that can harbor germs. If you do need to move around the cabin, avoid touching surfaces as much as possible and sanitize your hands afterward.

8. Be Mindful of What You Touch

Beyond disinfecting your immediate space, be conscious of what you touch throughout the flight. Avoid touching your face, especially after touching any public surfaces. If you’re planning to eat or drink, make sure to sanitize your hands beforehand. Additionally, avoid using the seat-back pocket for storing personal items, as these pockets are rarely cleaned and can be a breeding ground for germs. Instead, keep your personal items in a clean, resealable bag and avoid placing them directly on surfaces.

Conclusion

Flying is an integral part of modern life, but it doesn't come without its risks, especially regarding exposure to germs. By following these eight strategies, you can significantly reduce your risk of getting sick while flying. Choose your seat wisely, disinfect your space, practice good hand hygiene, wear a mask, stay hydrated, use the airplane's ventilation system to your advantage, minimize movement around the cabin, and be mindful of what you touch. While no method can guarantee complete protection, these precautions can help you fly with peace of mind, knowing you’ve done your best to stay healthy.
