A rapid long-distance transmeridian travel can cause a physiological alteration to the body’s circadian rhythms, called jetlag. Someone flying from west to east can be more sensible for the symptoms. The condition of jetlag may last several days before the traveller is fully adjusted to the new time zone. Recovery period of one day per time zone crossed is a suggested guideline.
