OKLAHOMA CITY -- As the Thanksgiving holiday nears, Americans are preparing to travel far and wide to visit loved ones. But with holiday travel can come health risks.
Whether it's the common cold, swine flu or lesser known conditions like deep vein thrombosis, there are plenty of ways Americans on holiday can get sick while traveling. Still, a few precautions can increase your odds of staying healthy, said Oklahoma Medical Research Foundation President Stephen Prescott, M.D.
"I know it gets said a lot, but that's only because it's true -- washing your hands makes a big difference," said Prescott, a physician and medical researcher. "We pass and receive so many bugs that way. Washing with soap and warm water or using hand sanitizer before you get on the airplane or before you eat a meal can do a lot to keep you safe."
Some cold and flu viruses can survive on surfaces for a few days and even weeks. Washing your hands regularly can reduce your risk of getting ill by up to 50 percent.
Prescott said he uses jokes at family gatherings to get others to keep their hands clean.
"I tell them, just because you're having a few cups of spiked punch, doesn't mean you're safe," he said. "The alcohol in your margarita isn't a replacement for the alcohol in hand sanitizer."
Prescott also recommends drinking plenty of water to avoid dehydration. This is especially important when flying, because humidity levels on planes can sometimes drop to as little as 10 percent.
"Dehydration can leave your immune system prone to viruses and bacteria, and it can cause headaches and nausea," he said.
Those flying or driving long distances also should get up and out of their seats for a little movement, Prescott said. Although it's rare, sitting still too long can sometimes trigger deep vein thrombosis -- a potentially life-threatening circulatory disorder.
According to Prescott, getting a good night's sleep before travel can also help ward off illnesses.
"Our bodies need sleep to function. It's as simple as that," Prescott said. "If you don't get enough sleep, it can weaken the immune system, making you more susceptible to viruses."
And if you do come down with a cold or flu bug while on vacation, consider wearing a mask to spare your family the same fate.
"You may get some odd looks, but you'll be doing those around you a favor," Prescott said. "After all, everybody's trying to avoid getting sick. Just because you've already caught something doesn't mean the rest of us want it, too."
But this precaution does pose one problem come Thanksgiving night, said Prescott.
"It's hard to eat turkey and dressing when you're wearing a mask."
