Jet-lag affects every traveller to some extent. A major survey by FARSA, New Zealand's flight crew union, found in 1994 that 96 per cent of flight attendants arriving in New Zealand, one of the planet's longest-haul destinations, talked of jet-lag symptoms that contained weariness, loss of energy, lack of sleep and impaired motivation. Even those who claim they are immune often give themselves away by showing signs of bad temper, and frequently deny the symptoms in an attempt to override their body's natural reaction to global air travel.
The symptoms of jet lag include disorientation and bewilderment in addition to irritation and misguided annoyance. The most evident symptom is weariness; with numerous visitors feeling drained for days along with finding that they lack concentration and incentive. This may affect business abilities as well as impair the enjoyment of a vacation. Unfortunately, another symptom is that travellers wake in the middle of the night and then need to fall asleep during the daytime, which makes recovery from tiredness more difficult. These symptoms can persist for some time: the US space agency NASA estimates you want one day for every time-zone crossed to recover your normal rhythm and energy patterns.
The position is further exascerbated by some terribly obvious factors which make sure that air travel is a physically demanding experience. Dehydration due to the aircraft's compression could cause headaches, dry skin, and nasal irritation, which make passengers more at the mercy of the common and exotic viruses and bacteria given off by their fellow passengers and recirculated by the confined airflow system. The World Health Organisation links jet lag with the high occurrence of digestive disorders abroad. Guesstimating that about 50per cent of long distance passengers suffer from digestive problems, their report implies that, 'travel fatigue and jet-lag may aggravate the problem by reducing travellers ' resistance and making them more susceptible'.
The decompression and forced inactivity may also cause the swelling of limbs and feet which often prevents travellers from wearing their ordinary shoes for at least 24 hours on arrival. This is dangerous because swollen legs may cause blood clots which, when they break free, can lodge in the lungs and set off a pulmonary embolism. A 1988 report in The Lancet worked out that, over 3 years at Heathrow 18 % of the 61 sudden deaths of long-distance passengers were caused by clots on the lungs, a figure far higher than is the norm in the population-at-large.
The main cause of jetlag is crossing time zones. This has the consequence of putting the body's Orcadian Rhythms, which dictate what time you drop off, wake up and have meals, out of phase with the timescale of where you are going. Orcadian Rhythms are maintained by minute releases of hormones and seratonins in the blood to dictate appetite and sleep patterns. As these chemical triggers were developed when we were living in caves, it is perhaps understandable that they have trouble adapting to travel by supersonic plane and it takes them a little time to settle down to a new routine in a different time zone. Travellers flying east typically report worse symptoms, but smaller symptoms are also displayed going west and even those flying north or south or vice versa aren't immune. Many travellers are of the opinion that day flights cause less serious jetlag, but this might be mainly because they miss less sleep while travelling.
