Stress Levels at Heathrow May be Fatal

Travellers passing through Heathrow Airport are under so much psychological stress they may be at risk of death, a leading neurophyschologist says.

Dr David Lewis carried out an experiment on four travellers at Heathrow, attaching chest monitors to record heart rate, pressure pads on their arms to measure blood pressure and sensors on their fingertips to measure changes in physiological stress.

Lewis says passenger heart rates peaked at nearly four times the resting level for healthy adults, and physiological stress levels exceeded those recorded by Formula 1 drivers, free-fall parachutists and victims of knifepoint muggings, UK newspaper The Times reports.

"The conditions at Heathrow Airport and the stress levels that passengers are routinely subject to poses a very grave danger to the health of travellers at the airport," Lewis says.

"This condition is known medically as tachycardia, which can at times prove fatal. Even under intense exercise you wouldn't normally see these levels, which given that our travellers were not exerting themselves physically, reflects the high level of psychological stress they were under."

The study, carried out on behalf of airline Silverjet, claims that the main causes of the stress were queues, unfriendly and impatient staff, lack of information, burly security and inadequate facilities.
