Many medical experts have found that air travelers usually experience a worse bout of jet lag when they fly from east to west.  In general, the more time zones that they cross, flying from east to west, the more severe their symptoms of jet lag will be.

When flying on commercial airlines, airline passengers can develop some medical problems which tend to be minor.  However, some symptoms may develop into more serious medical conditions, such as deep vein thrombosis, which can quickly become life threatening.

The fear of flying is called Aviophobia.  There are millions of vacationers and business people who travel on commercial air flights as well as potential flyers worldwide that suffer from it, to a greater or lesser extent.  Even though air travel is about thirty times safer than traveling by car, you very rarely hear about people that have a fear of driving.

Commercial air flights cause airline passengers’ blood to become thicker and slow down, especially in the lower extremities, which can increase the possibility of developing blood clots.  The longer the flight, the greater the medical risk.
