Falling luggage, toxic cabin air and dirty water-these are just some of the ways in which air travel can harm your health.
Travelers face a range of potential health hazards from the moment they step into the airport and here are just some of the potential problems awaiting you every time you fly:
Struck by falling luggage
Luggage falling from overhead lockers is another common cause of mid-air pain, with injuries ranging from cuts and bruises to severe head trauma.
"There is compelling evidence that flight attendants and passengers are being injured by excess amounts of oversized carry-on items," the Daily Telegraph quoted US Association of Flight Attendants-CWA International President Patricia Friend as saying.
Full-body scanner cancer link
Some scientists fear radiation from the controversial "naked" full-body airport scanners has been dangerously underestimated and could increase the risk of skin cancer.
University of California biochemist David Agard has said that unlike other scanners, the radiation from these devices is delivered at low energy beam levels, with most of the dose concentrated in the skin and underlying tissue.
David Brenner, the head of Columbia University's Center for Radiological Research, says the radiation dose to the skin is actually 20 times higher than the official estimate.
Toxic cabin air
Breathing contaminated air cause can cause drowsiness, headaches, respiratory problems or neurological illnesses.
A 2009 investigation into some of the world's most popular airlines found high levels of a toxin found in modern jet oil fuel inside the cabins.
Ear damage fears
Pain, bleeding and even a ruptured eardrum can happen to passengers experiencing changes in air pressure during flight.
The problem happens if the air pressure in the middle ear and sinuses becomes much higher or lower than the surrounding pressure, warned the Aerospace Medical Association.
This can happen if you have a blockage of any of the passageways caused by infection, allergy or bleeding.
Airports a 'hotbed of germs'
Before even stepping on the plane travelers are at risk of falling ill because of "filthy" airports.
Transmission of cold, viruses
The spread of colds and flu continues onboard, with a 2004 study finding that travelers are about 100 times more likely to catch a cold on a plane than they are in normal daily life.
Blood clot risks
An increased risk of deep vein thrombosis in air travelers has been widely reported and a recent US study has strengthened the case.
Researchers found that travel was associated with a nearly three-fold increase in the risk of developing blood clots in the veins, especially in the legs.
If the clot dislodges and travels to the lungs it can cause a potentially fatal condition called a pulmonary embolism with the clot risk growing with the length of the trip.
Cabin crew have warned travelers to avoid drinking water from aircraft taps.
Radiation from lightning
Lightning or the related phenomena of terrestrial gamma-ray flashes could expose airline passengers to levels of radiation equivalent to 400 chest X-rays, according to estimates by a study in the Journal of Geophysical Research - Atmospheres.
