Five tips for staying healthy this holiday season

By Alexa Pozniak, Tufts Medical Center correspondent

Whether it’s by car, bus, train, or plane, traveling has become synonymous with the holiday season for millions of Americans. And while it’s customary to spread joy and cheer this time of year, coming into close proximity with a variety of people, oftentimes in a confined space, can also spread germs.

“For the most part, when we think about catching germs from other travelers, it’s really viruses that we’re most concerned about,” explains Dr. Shira Doron, an infectious disease specialist.

“It’s relatively rare for a passenger to be carrying a germ that is transmitted by circulating through the air; the more common infections are spread through droplets or secretions,” Dr. Doron explains. “Your biggest risk is getting coughed or sneezed on, or touching something with germs on it.”

No matter what mode of transportation you choose, Dr. Doron suggests five top tips to keep you healthy through the holidays.


Practice good hand hygiene

Washing your hands on a regular basis is essential to stopping the spread of infection, and can dramatically reduce your chances of getting sick. The Centers for Disease Control (CDC) recommends working up a lather and then rubbing your hands together for 20 seconds or as long as it takes you to sing the “Happy Birthday” song to yourself twice. If you don’t have access to a faucet, hand sanitizer is a great substitute as long as it contains at least 60 percent alcohol. Keep your hands away from your face at all times.


Eat immune-boosting foods

The best way to combat germs is with a strong immune system. Maintain a healthy diet before, during and after your trip. Include plenty of protein, healthy fat, and a balance of vitamins and minerals with a minimum of processed ingredients and sugar.



Air systems on airplanes work quite well at filtering out germs, but the air is dry. According to a study published in the Journal of Environmental Far merits Research, this increases the risk of getting sick. A thin layer of mucus in your nose and throat normally flushes out germs. But when it becomes dry, your body is more vulnerable to invasion. Drink water throughout your trip, and don’t overdo it on alcoholic beverages and caffeinated drinks, which can further dehydrate the body.



Sleep deprivation can weaken the immune system and make your body more vulnerable to infection. So set out on your trip well rested, aiming for eight hours of shut-eye each night in the days leading up to your departure date.


Flu Shot

Since the holidays coincide with peak flu season, get the flu shot. It may prevent you from getting sick, or if you do get sick, it may make your illness milder.
