What is jet lag?
Jet lag (also known as desynchronizes) is a common sleep disorder at the best addiction treatment center in Karachi. Most importantly, it is a symptom or set of symptoms, and also many people talk about Treating insomnia with melatonin as the best and the better response for the cure. When we talk about a jet lag remedy or a jet lag cure, we are not talking about overcoming jet lag directly but are looking at treating the underlying cause or causes. Jet lag affects millions of long-haul travellers daily, for pleasure or business. In a recent survey of international business travellers, 74% said they frequently suffered from jet lag.
What causes jet lag?
Jet lag is caused by a significant and rapid change in time zones, resulting in a difference between the local time and time recorded by your body's internal clock.
For example, let's say you leave London
at 9 pm and fly to Singapore. The flight lasts 12 hours, and you land in
Singapore at 9 am London time. However, because you have passed across several world time zones, the local time in Singapore is 3 pm.
In the space of just 12 hours, you have
flown halfway around the world, and your body clock now says that it is 9 am,
although the actual time in Singapore is 3 pm.
So you can see the problem. Later in
the day, when everybody else is going to bed, your body clock will still show
the time as late afternoon, and you won't be ready for bed yet. Similarly, the
following morning when the bus arrives at your hotel at 10 am to take you on a
sightseeing tour, your body clock will still be registering at 4 am, and you
will be looking for a few more hours of sleep before you get up and going.
Your body contains its internal clock,
powered by the environment around you, including temperature, humidity and, in
particular, the average daily change between
daylight and darkness. These environmental factors cause your internal clock to
run, like a standard clock, on a series of 24-hour cycles,
sometimes referred to as your body's circadian rhythms.
Your body clock, in turn, triggers
certain events within your body, the most obvious of which is telling your body
when to shut down for sleep and when to wake up and get going.
The fact that your body clock is out of
step with local time upsets the whole rhythm of your day, giving rise to
problems sleeping at night, staying awake during the day and eating when you
wouldn't normally eat, amongst other things.
Who suffers from jet lag?
Anybody travelling across several world
time zones in a short time is liable to suffer the effects of jet lag. Crossing
just one or two time zones is unlikely to cause problems, but travelling three or more is likely to give rise to jet lag,
with jet lag symptoms becoming increasingly pronounced and staying with you for
longer as the number of time zones increases.
Jet lag affects men and women
regardless of age, although people over 50 are likely to suffer more than those
under 30.
