Deep Vein Thrombosis
Blood clots can form in the legs during flights, chiefly because of prolonged immobility. This formation of clots is known
as deep vein thrombosis (DVT), and the longer the flight, the greater the risk. Although most blood clots are reabsorbed
uneventfully, some might break off and travel through the blood vessels to the lungs, where they could cause life-threaten-
ing complications.
The chief symptom of DVT is swelling or pain of the foot, ankle or calf, usually but not always on just one side. When
a blood clot travels to the lungs, it could cause chest pain and breathing difficulty. Travellers with any of these symptoms
should immediately seek medical attention.
To prevent the development of DVT on flights you should walk about the cabin, perform isometric compressions of the
leg muscles (ie contract the leg muscles while sitting), drink plenty of fluids and avoid alcohol.
Jet Lag & Motion Sickness
If you're crossing more than five time zones you could suffer jet lag, resulting in insomnia, fatigue, malaise or nausea. To
avoid jet lag drink plenty of (nonalcoholic) fluids and eat light meals. Upon arrival, get exposure to natural sunlight and
readjust your schedule (for meals, sleep, etc) as soon as possible.
Antihistamines such as dimenhydrinate (Dramamine) and meclizine (Antivert, Bonine) are usually the first choice for
treating motion sickness. The main side effect of these drugs is drowsiness. A herbal alternative is ginger (in the form of
ginger tea, ginger biscuits or crystallised ginger), which works like a charm for some people.
