What is jet lag at all?
|
|
| |
One university study showed that as many
as 94% of long distance travellers experienced some
form of jet lag.
Other research including flight staff indicated that even flight
attendants are not immune. Jet lag includes such physical symptoms
as fatigue, insomnia, disorientation, headaches, bowel irregularity
and light-headedness.
In some cases this may include swelling limbs or/and irritations
of ear/nose/eyes.

It can impede both your physical
and mental performance.
Jet lag occurs because changes in time zones confuse
the body inner clock.
The body's 24-hour inner clock drives by a system
called "circadian rhythms." |

It can take as long as one day to adjust for each time zone you
cross. It is not the length of your flight that will determine
how much jet lag you might experience but how many time zones
you have gone through. Jet lag seems to be worse flying eastward.
Traveling north to south within the same time zone,
on the other hand, produces none. In addition, your general health,
personal habits and age play a part in your susceptibility to jet
lag.

For example, babies are
scarcely bothered by it.
For adults, being well rested can help reduce jet lag symptoms while
overeating, smoking and drinking alcohol can make it worse. |
