Germ Hot Spots: The Plane Edition
Studies show that germs can travel easily on an airplane, where people are packed together tightly.
For example, a woman on a 1994 flight from Chicago to Honolulu transmitted drug-resistant tuberculosis to at least six of her fellow passengers, according to a New England Journal of Medicine study.
In 2003, 22 people came down with SARS, or severe acute respiratory syndrome, from a single fellow passenger who had SARS but didn’t have any symptoms, according to another New England journal study.
The surfaces that have tested highest for bacteria and other infection-causing germs include:
- Security check points
- Airplane blankets and pillows.
- Latches for overhead bins
- Tray tables
- Tv screens/monitors
Here are five ways to avoid germs while traveling on a plane, as well as when you first arrive and leave the airport.
Sit towards the front. Ventilation systems on most commercial aircraft provide better air flow in the front of the aircraft.
Try to avoid coffee or tea on an airplane. Monitoring by the Environmental Protection Agency shows that water in airplanes’ water tanks isn’t always clean — and coffee and tea are usually made from that water, not from bottled water, according to Victoria Day, a spokeswoman for the Air Transport Association.
The EPA advises anyone with a suppressed immune system or anyone who’s “concerned” about bacteria to refrain from drinking coffee or tea on an airplane.
“While boiling water for one minute will remove pathogens from drinking water, the water used to prepare coffee and tea aboard a plane is not generally brought to a sufficiently high temperature to guarantee that pathogens are killed,” according to the EPA’s Web site.
According to the EPA, out of 7,812 water samples taken from 2,316 aircraft, 2.8 percent were positive for coliform bacteria. Although that sounds like a small number, this means 222 samples contained coliform bacteria.
If possible, try bringing your own bottle of water, coffee or tea onto the plane.
Sanitize your hands after using the bathroom. Obviously, a toilet on an airplane “is among the germiest that you will encounter almost anywhere,” said Charles Gerba, an environmental microbiologist at the University of Arizona. “We always find E. coli on surfaces in airplane restrooms.”
Since you’ll probably touch the bathroom door handle while returning to your seat, sanitize your hands again when you return to your seat.
Wash or sanitize your hands after getting off an escalator. Tests show that high-volume surfaces like escalator handrails in airports are full of germs.
Wash or sanitize your hands after using an ATMs. ATMs, especially in busy places like airports, are also full of germs.
Keeping your hands clean is crucial. Why? Because you’re touching surfaces that have been touched by thousands of people before you.
Immunity-Boosting Foods You Should Be Eating
Whether it’s cold out, or the whether the weather is transitioning from cooler to warmer temperatures, dietitians point to a significant defense weapon in preventing colds and the flu.
Immune-boosting foods can improve your ability to ward off the flu and other health problems, according to the Academy of Nutrition and Dietetics.
“A strong immune system doesn’t guarantee your body can fight off every flu bug, but it is a powerful defense,” said registered dietician Heather Mangieri in an academy news release. “Good nutrition is essential to a strong immune response.”
The following overview of foods may boost the immune system:
- Protein is an essential part of your body’s defense system. Sources of protein include seafood, lean meat, poultry, eggs, beans and peas, soy products and unsalted nuts and seeds.
- Vitamin A helps prevent infections by keeping the skin and tissues in the mouth, stomach, lungs and intestines healthy. This nutrient, found in sweet potatoes, carrots, kale, spinach and red bell peppers, also helps the body regulate the immune system.
- Vitamin C triggers the production of immune-boosting antibodies. Oranges, grapefruit, strawberries and tangerines are among the foods rich in vitamin C.
- Vitamin E is an antioxidant that may provide a boost to the immune system. People who want to get more vitamin E in their diet should eat sunflower seeds, almonds, sunflower or safflower oil, hazelnuts, peanut butter or spinach.
- Zinc, a nutrient found in lean beef, wheat germ, crab, wheat bran, sunflower seeds, black-eyed peas, almonds, milk and tofu, may also improve functioning of the immune system.
If you’re unsure about what foods to eat to boost your immune system, a registered dietitian can help. They can help ensure you’re getting the nutrients your body needs to function and protect itself.
