Science catches up with jet lag
Questions:
1. What are the
effects of jet lags?
2. How it impacts travelers on board the flight?
3. How the biological clock work in human body?
Answer-
Introduction
In this era of science we have seen many inventions which
are beneficial for us. But if we look on the other side then we can see many
disadvantages too. Everything has two sides, one is good and one is bad. Same
is the case with science. People cannot clearly see the problems that science
has brought us. In this story there is disadvantages of Jet lag, how it affects
human body is described here. There are so many adverse effects of Jet lag in
human body because our body is cannot work properly with the speed of Jet. It
can’t cope with it.
Jet Lag
Modern Jets are best invention of science which makes world
smaller by flying at more than 900 km an hour. It can reach to the far away
places in shorter period of time. For example, we can leave Delhi at 4.00 in
the morning, eat an early breakfast in the sky, over Kabul, and be in London in
time for Lunch by about 1.00 pm.
Problems regarding Jet Lag
When we are travelling from one place to other then we have
to adjust our self according to the time of that particular country. For
example, when we are travelling from Delhi to London then there is vast
difference in time zone. Delhi timings is totally different from London
timings. If you leave from Delhi at Morning time and about to reach London
after 8 hours then you will expect that it will be noon time there, but
unfortunately there is also morning time. Means time moves for only 3 and half
hour, even if you are travelling for 8 hours. That is only because of
geographical location of country. Sun rises earlier in India as compared to
London.
Adverse effect of Jet lag on our body
The speed of Jet lag is enemy for our body. Our body takes
time to adjust. Jet lag did not provide proper time. It makes our journey
shorter. Our biological clock requires time to adjust itself. We can adjust our
wrist watch easily but our internal clock will take time. We have left Delhi
thousands km behind, our body and mind still seem to be controlled by the
things happening there. Our body follows the cycle of day and night. The
temperature of the body rises and falls at regular hours. Similarly our kidneys
are also controlled during night, producing very little urine. In this way all
our activities, our habits of sleep, work and hunger follow the biological
clock. If this clock is disturbed then there is trouble.
Politicians, Pilots and businessman
The people who suffer from it more are Pilots, Politicians
and businessman. Jet pilots are constantly moving from one time zone to other.
For them it is very tough task to deal with the adverse effect. Similarly for businessman there is great deal
of suffering because if they are on important meeting in London, then they have
to fight to keep themselves awake when others are full of energy. Even the
politicians who are going to deal with important speech suffer a lot to keep
them active.
An experiment
An experiment was conducted in England on 8 men and 6 women
to check the adverse effect of high speed travelling on their bodies. They had to
pass through 9 different time zones. Throughout they were given different tests
like, temperature, heart rate, blood pressure, respiration etc.
Result of the experiment
When people travel from one time zone to another, their body
temperature, heart rate, blood pressure etc moved away from normal and it
requires many days to come back to normal. Travelling also had an effect on
minds of these people. Their power of concentration and ability to make
decisions quickly decreased. Emotional disturbance were also common. Men become
short tempered and women become nervous.
Conclusion
Therefore our body requires at least 24 hours adjusting
itself to local conditions. Nature never wanted us to travel so fast. High
speed travel, which is one of the gifts of modern science, seems to be one of
the greatest enemies of these natural rhythms. In old days people are
travelling at gentle speed and body was able to adjust itself to local time,
but jet planes which travel as fast as the sun given no time to re-set its
biological clock.
