What is jet lag? Jet lag is when your body clock (circadian rhythm) falls out of sync with your current time zone. This is mainly due to travelling across time zones but it can be experienced by shift-workers, particularly those who work late nights. Symptoms can include poor sleep, waking up in the middle of the night and staying wide awake, but then being tired the following day and falling asleep early in the evening. There are many other symptoms too, such as malaise, headache, nausea, appetite change, irritability (which is not too surprising since you are not sleeping) and light sensitivity.

How long does jet lag take to go away? In general, jet lag should dissipate after an average of one day for every 1-2 hours your time zone changes (some people also experience it when daylight savings changes). So if you travel to a time zone where the difference is six or seven hours, expect it to take three-five days. If you follow the tips on this site, it can be shorter. However if you are not careful in your planning or making a few small changes, it can take longer and lead to insomnia.
Does direction of travel affect jet lag? Absolutely, but there is little difference once the time change is around 11-13 hours but typically travelling east-west is easier to get over, than west-east. Think of it like how easier it is to stay up, say, two hours later on the weekend - sleep will generally come quickly. But then think how difficult sleep is if you try to go bed two hours earlier than normal - you'll probably lie there for a long time.
Can I do something to minimise jet lag before I travel? There are a number of crucial things you can do to help reduce the impact of jet lag. The four main areas are planning your travel, the days leading up to departure, while you are travelling and afterwards.

For travellers, Viagra can apparently help with adjusting your body clock but there are a number of important points to consider.
