Why Do We Suffer From Jet Lag

Jet Lag impacts every traveller to some degree. A major survey by FARSA, New Zealand's flight crew union, discovered in 1994 that 96 per cent of flight attendants arriving in New Zealand, one from the world's longest-haul destinations, complained of jet lag symptoms that included tiredness, loss of power, broken sleep and impaired motivation. Even those who claim they may be immune frequently give themselves away by revealing slips of undesirable temper, and often deny the symptoms in an attempt to override their body's natural reaction to international air travel.

The symptoms of jet lag include disorientation and confusion, at the same time as irritability and irrational anger. Probably the most obvious symptom is tiredness; with many travellers feeling drained for days, too as obtaining that they lack concentration and motivation. This could influence company abilities as well as impair the enjoyment of a vacation. Regrettably, yet another symptom is the fact that travellers wake within the middle from the evening and desire to fall asleep through the day, which makes recovery from tiredness much more difficult. These symptoms can final for some time: the US space agency NASA estimates you'll need 1 day for each time-zone crossed to recover normal rhythm and power patterns.

The predicament is additional complex by some very clear aspects which ensure that air travel is actually a physically stressful experience. Dehydration caused by the aircraft's compression may cause headaches, dry skin, and nasal irritation, which make travellers a lot more susceptible for the typical and exotic viruses and bacteria offered off by their fellow passengers and recirculated by the confined airflow system. The Planet Well being Organisation links jet lag with the higher incidence of digestive issues abroad. Estimating that about 50 per cent of extended distance travellers suffer from digestive problems, their report suggests that, 'travel fatigue and jet lag may aggravate the problem by reducing travellers' resistance and making them a lot more susceptible'.

The decompression and forced inactivity also can cause the swelling of limbs and feet which often prevents travellers from wearing their standard shoes for as much as 24 hours on arrival. That is dangerous due to the fact swollen legs may cause blood clots which, once they break totally free, can lodge in the lungs and result in a pulmonary embolism. A 1988 report inside the Lancet estimated that, more than three years at Heathrow Airport, 18 per cent in the 61 sudden deaths of long-distance passengers were triggered by clots on the lungs, a figure far higher than the incidence within the common population.

The main lead to of jet lag is crossing time zones. This has the effect of putting the body's Orcadian Rhythms, which dictate what time you visit sleep, wake up and have meals, out of phase using the timescale of one's new destination. Orcadian Rhythms are maintained by minute releases of hormones and seratonins within the blood to dictate appetite and sleep patterns. As these chemical triggers were developed when we had been living in caves, it is maybe understandable that they've difficulty adapting to travel by supersonic plane and it takes them some time to settle down to a brand new routine in a various time zone. Travellers flying east usually report worse symptoms, but lesser symptoms are also displayed going west and also these flying north or south or vice versa are not immune. Many travellers really feel that day flights incur much less serious jet lag, but this may be partly due to the fact they miss significantly less sleep even though travelling.
