Whether
you're a "Road Warrior" who has piled up thousands
of Frequent Flier Miles, or someone who is planning a vacation
to a distant location, you are likely to experience the phenomenon
of "jet lag," which can have a profound effect on
your sleep and alertness. This online brochure has some advice
for travelers on what you can do now to help get a better
night's sleep, when you arrive at your destination and when
you return home.
Jet Lag: The Traveling Sleep Disorder
Every
day, millions of travelers struggle against one of the most
common sleep disordersjet lag. For years, jet lag was
considered merely a state of mind. Now, studies have shown
that the condition actually results from an imbalance in our
body's natural "biological clock" caused by traveling
to different time zones. Basically, our bodies work on a 24-hour
cycle called "circadian rhythms." These rhythms
are measured by the distinct rise and fall of body temperature,
plasma levels of certain hormones and other biological conditions.
All of these are influenced by our exposure to sunlight and
help determine when we sleep and when we wake.
When
traveling to a new time zone, our circadian rhythms are slow
to adjust and remain on their original biological schedule
for several days. This results in our bodies telling us it
is time to sleep, when it's actually the middle of the afternoon,
or it makes us want to stay awake when it is late at night.
This experience is known as jet lag.
Taking
the Air out of Jet Lag
Some
simple behavioral adjustments before, during and after arrival
at your destination can help minimize some of the side effects
of jet lag.
