The Science Behind Getting Sick After Flying

Have you ever noticed that every time you take a flight, you end up getting sick within a day or two after landing? You're not alone. Many people have reported similar experiences, and there are several scientific explanations that may contribute to this phenomenon.

The Role of Air Pressure and Humidity

One possible explanation is that the low air pressure and dry air on planes can weaken our immune system, making us more susceptible to illness. When we fly, the air pressure drops, which can cause our body to expand and contract. This can lead to dehydration, which can weaken our immune system. Additionally, the dry air on planes can dry out our mucous membranes, making it harder for our body to fight off infections.

But is there any evidence to support this theory? A study published in the journal Aviation, Space, and Environmental Medicine found that the low air pressure and humidity on planes can indeed weaken our immune system. The study found that the immune system of passengers on a flight from New York to Los Angeles was significantly weaker than that of passengers on a similar flight that took off at a higher altitude.

The Danger of Airborne Pathogens

Another possible explanation is that airborne pathogens can survive for long periods of time on surfaces and in the air. These pathogens can be spread through the air by coughing, sneezing, or even talking. They can also be spread through contact with contaminated surfaces, such as doorknobs, handrails, and airplane seats.

Recent studies have shown that airborne pathogens can survive for up to 24 hours on surfaces, and even longer in certain conditions. For example, a study published in the journal Emerging Infectious Diseases found that the H1N1 flu virus could survive on surfaces for up to 24 hours, and even longer in dry conditions.

Protecting Yourself

So, what can you do to protect yourself from getting sick after flying? Here are a few tips:

• Wash your hands frequently with soap and water, especially after touching surfaces that may be contaminated.

• Use hand sanitizer if soap and water are not available.

• Avoid close contact with other passengers, especially if they are sick.

• Try to steer clear of surfaces that may be contaminated, such as doorknobs and handrails.

• Drink plenty of water to stay hydrated, and avoid sugary drinks that can dehydrate you.

• Consider taking supplements, such as vitamin C and probiotics, to boost your immune system.

Recent Studies and Research

There have been several recent studies and research papers published on the topic of getting sick after flying. Some of the most interesting findings include:

• A study published in the journal Environmental Health Perspectives found that the air on planes can be contaminated with airborne pathogens, such as bacteria and viruses.

• A study published in the journal Aviation, Space, and Environmental Medicine found that the low air pressure and humidity on planes can weaken the immune system of passengers.

• A study published in the journal Emerging Infectious Diseases found that airborne pathogens can survive for up to 24 hours on surfaces, and even longer in dry conditions.

By understanding the science behind getting sick after flying, you can take steps to protect yourself and stay healthy on your next flight.
