Its hard to imagine a worse place to get sick than on an airplane. But unfortunately, it happens in many forms.

There are a number of unpleasant and even potentially dangerous conditions that travelers can develop during a flight. Nausea, diarrhea, headaches, dizziness, congestion, blood clots, sinus infections, tinnitus travelers may find themselves dealing with these problems once theyre in the air.

A bad sinus infection can sometimes worsen when you fly because of the change in air pressure, Dr. Danielle Qing , an assistant professor and internal medicine specialist at Mount Sinai, told HuffPost. This can lead to a popping sensation in your eardrums, and in very rare instances can sometimes cause your eardrum to perforate. And then, of course, theres motion sickness, which can look like nausea, vomiting, headaches and lightheadedness. Turbulence can make it even worse.

Getting sick while flying can be hard to handle. As Dr. Daniel Chandler , a primary care physician at Tufts Medical Center, told HuffPost, Airplanes are funny places because things that would be so easy to fix on the ground are more difficult to fix in the air due to a lack of resources and people to fix it.

Still, there are steps you can take to alleviate the issue if you get sick on a plane. HuffPost asked doctors to share their advice for dealing with in-flight illnesses.

Avoid looking at screens.

If you are experiencing motion sickness, try to avoid things that are visual like your phone or the plane TVs, Chandler said. Instead, sleep. But if you cant sleep, listen to something like music, a podcast or an audiobook.

If youre trying to stave off nausea, he also advised against looking at the vomit bags in the seats, as that might make you feel more nauseous.

Stare at the horizon if you are in a window seat, Dr. Rabia De Latour , a gastroenterologist and assistant professor of medicine at NYU Grossman School of Medicine, said. She also recommended avoiding unnecessarily moving your head.

Qing offered similar advice in the event of dizziness.

Closing your eyes and applying a cold compress can often lessen the symptoms, she said.

Hydrate, hydrate, hydrate.

If youre experiencing nausea or gastrointestinal symptoms, do your best to stay hydrated, as dehydration can worsen your condition. Be sure to drink your fluids slowly and carefully, however, to avoid another trip to the bathroom.

Attempt hydration with water, not carbonated beverages, De Latour said.

The airplane cabin environment can be very dehydrating , so even if you arent feeling sick, take extra care to drink plenty of water on flight days. Getting ample H2O can help with headaches and dizziness as well.

People arent drinking enough water when they travel, so dehydration is a common reason for headaches during a flight, Chandler said. Sometimes dizziness is just a version of motion sickness, but sometimes it can be from dehydration, too. Particularly if you had alcohol, take in some extra water.

Try to eat a little food.

Sometimes, eating is the last thing you want to do when youre feeling sick. But do what you can to get a little something down.

Try some bread or crackers, Chandler said. Having a small amount of bland food in your stomach can actually take away a little bit of that nausea.

Many experts recommend the BRAT diet bananas, rice, applesauce and toast in cases of nausea, vomiting and/or diarrhea. Travelers with chronic conditions should try to pack helpful snacks in their bags, too.

If you are diabetic or taking insulin, make sure you bring some candy or snacks on board in case your blood sugar gets too low, Qing said.

Take medicine.

When you travel, its always a good idea to keep an extra supply of medication handy, especially if you have certain chronic conditions, such as diabetes or angina, Qing said. Having at least seven days of your medications in your carry-on is a helpful precaution, especially if your checked bag gets lost.

For example, if you have a seizure disorder, she recommended that you have your seizure medications handy in case of an emergency. Those with coronary artery disease or angina should bring their nitroglycerin tablets, and anyone with a history of anaphylaxis should bring an EpiPen, in addition to informing the airline of allergy concerns.

If youve experienced motion sickness while traveling, take medication like Dramamine to help with that, Chandler said.

He noted that many travelers pack medications like ibuprofen, aspirin, Pepto-Bismol, Tylenol, Benadryl and Excedrin to address potential health issues, especially if they have a previous history.

Travelers diarrhea is quite common, so if youre traveling to a country where that often happens, you might want to bring medicine for it, Chandler said. Usually its a crummy 12 to 24 hours that you just have to tough out. But you need to stay hydrated.
