CNN Health interviewed Dr. Mark Gendreau, a senior staff physician at the Lahey Clinic in Burlington, Massachusetts, who offers five simple things we can all do to avoid getting sick while traveling: 

1. Sit toward the front of the airplane

“Pick a seat near the front, since ventilation systems on most commercial aircraft provide better air flow in the front of the aircraft,” Gendreau advised. If you can afford it, sit in first class, where people aren’t so squished together.

2. Don’t drink 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.

3. Sanitize your hands after leaving an airplane bathroom

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 who’s also known as “Dr. Germ.”

“You have 50 people per toilet, unless you are flying a discount airline; then it is 75,” Gerba said. “We always find E. coli on surfaces in airplane restrooms.”

You should wash your hands after using the restroom, but because the water itself might have harmful bacteria (see No. 2 above) and because the door handle on your way out has been touched by all those who went before you, Gendreau also advises sanitizing your hands when you return to your seat.

4. Wash or sanitize your hands after getting off an escalator

Gendreau says tests show that escalators in airports are full of germs. To confirm these tests, here’s a fun activity while you wait for your flight this Thanksgiving: Look at your watch, and count how many people get an escalator in a five-minute time period. Multiply that by 12, and you have how many people are on that escalator every hour. High-volume handrails are why Gendreau sanitizes his hands as soon as he can after he exits an escalator.

5. Wash or sanitize your hands after using an ATM

Gendreau says ATMs, especially in busy places like airports, are full of germs. As with escalators, he sanitizes ASAP after using one. 

Gendreau says that keeping healthy while traveling can be summed up in six words: “hand hygiene, hand hygiene, hand hygiene.”

Keeping your hands clean is crucial, he says, when you’re spending the day touching surfaces that have been touched by hundreds or thousands of people before you.

A new study, discussed in Scientific American, indicates that the impact of stress may be greater on our physical bodies than previously thought, especially our immune systems.

It might seem counterintuitive, but Kiecolt-Glaser believes that stress makes our immune systems less effective because it actually elicits an immune response itself. Stress, she says, causes the body to release pro-inflammatory cytokines, immune factors that initiate responses against infections. When the body produces these cytokines over long periods of time—for instance, as a result of chronic stress—all sorts of bad things can happen. Not only does it hamper our body’s ability to fight infection and heal wounds, but chronic inflammation also increases our risk of heart disease, osteoporosis, and autoimmune diseases including type 2 diabetes.

What’s more, because regular stress causes a chronic immune response, it can also increase a person’s risk for allergies, which occur when the body elicits a chronic immune response against something that’s not really dangerous (like pollen). In her most recent study, announced yesterday, Kiecolt-Glaser found that when people are under lots of stress—for instance, when they are forced to deliver a speech or do difficult math problems on the spot—their allergies worsen over the course of the next day.

Discussion Question: Experiencing stress is not inevitable; it’s about responding in a manner that helps you rather than hurts you. What small steps can you take this semester to manage your stress more effectively?

Wesleyan Resources: Stress Management

Millions of Americans took the advice to get a flu shot this season, but many are still becoming infected with the flu. This flu season is lasting longer than initially expected and has introduced unforeseen new strains of the virus, making other flu prevention steps even more important. Today, the Visiting Nurse Associations of America (VNAA) and The Clorox Company launched the inFLUenza Resource Center, an online resource with tips and tools needed to help protect families and help prevent the spread of the flu virus.

“While it is important to get vaccinated to protect yourself from contracting influenza, there are many common sense actions you can take to help protect your family and help prevent the spread of the flu virus,” stated Shelley Ludwick, Clinical Director of the Visiting Nurse Associations of America. “Our new inFLUenza Resource Center includes easy tips to help you protect your family.”

Even after suffering 10 days with a head cold, antibiotics won’t help your stuffy sinuses get better.

Antibiotics don’t help virus infections, the cause of most head colds. But after an adult patient has suffered stuffy sinuses for a week to 10 days, most doctors offer antibiotic treatment in case a bacterial infection has set in. Doctors may offer antibiotics even more promptly if the sinus infection is dripping thick green phlegm into the throat.

But nasty snot or not, antibiotics aren’t likely to help, find Jim Young, PhD, of University Hospital, Basel, Switzerland, and colleagues. read full article…
