Nov 6th 2008 Countering The Symptoms Of Jet Lag By Breaking Up Your Journey
Jet lag occurs whenever you travel and you internal body clock’s time is out of balance with the local time at your destination. For example, if you leave London at 9 pm and fly to Bangkok you will land some 13 hours later when the time in London is now 10 am the following morning. However, because you have traveled across several time zones, the local time at Bangkok airport is now 4 pm that same afternoon.
Having taken a taxi to your hotel, checked in had taken a shower your body will now be telling you that it is time to eat. Now, your body clock thinks that it is time for lunch and, although everyone else is having dinner, it doesn’t matter to your body clock what you call the meal, it only cares that you eat. So far so good, however, a couple of hours later when everyone else starts going to bed your problems will start because your body clock believes it is now only late afternoon.
A time difference of 6 hours, such as that shown in this illustration, is substantial and even the best of us will be feeling the effects of jet lag. Indeed, while a couple of hours will hardly be noticeable, anything over about 4 hours can be expected to produce the symptoms of jet lag in most people.
Of course there are various things that you can do before your journey, during the course of your flight and at your destination to help to reduce jet lag but one difficulty which researchers have found recently is that when your internal body clock experiences a significant shift in time it usually overcompensates when adjusting and therefore leaves you suffering a double dose of jet lag for a while before it eventually settles down. Against this background, how can you counteract this?
Well, it is possible to take this into account to a certain extent and reduce any symptoms of jet lag by beginning to adjust your body clock before you travel, but circumstances might make this difficult. An alternative therefore is to simply break your journey if you are going to be traveling across more than 4 or 5 time zones.
In the case of our illustrative trip to Thailand this might for example mean breaking your journey half way and relaxing for a day before continuing on. Air travel might have made the world smaller today but I’m afraid that it is going to take the human body a little longer to catch up to modern technology.
