INSUBCONTINENT EXCLUSIVE:
For decades, travelers have stoically endured jet lag as an unavoidable menace on long journeys
Now, as airlines push for record-breaking non-stop flights halfway around the planet, efforts to counter the debilitating symptoms are
turning into a billion-dollar industry.Fresh insight into the physical and emotional toll of ultra-long haul travel should emerge this
weekend when Qantas Airways Ltd
flies direct from New York to Sydney
No airline has ever completed that route without stopping
At nearly 20 hours, it's set to be the world's longest flight, leaving the U.S
on Friday and landing in Australia during its Sunday morning.This will be more than an endurance exercise
Scientists and medical researchers in the cabin will turn Qantas' brand-new Boeing Co
Dreamliner into a high-altitude laboratory
They'll screen the brains of the pilots for alertness, while monitoring the food, sleep and activity of the few dozen passengers - including
The aim is to see how humans hold up to the ordeal.The proliferation of super-long flights - Singapore Airlines Ltd
resumed non-stop services to New York last year - is partly driven by the development of lighter, more aerodynamic aircraft that can fly
further.The physical burden on customers is putting a renewed focus on jet lag, and creating a supermarket of products and homemade
creations to ease the suffering
In that shopping basket: melatonin tablets, Pfizer Inc.'s anti-anxiety medication Xanax, and Propeaq light-emitting glasses that claim to
get the body back on track
And yes, there's an app for that and many other potential remedies.The potential customer base is staggering
The International Air Transport Association expects some 4.6 billion people to take a flight in 2019, a total that will jump to 8.2 billion
in 2037.Demand for jet-lag therapies is growing at about 6% each year and the industry will be worth $732 million in 2023, according to BIS
The broader sleeping-disorder market - dominated by pills - is worth $1.5 billion and will swell to $1.7 billion by 2023, GlobalData says,
adding that more than 80 drugs targeting disturbed sleep are in clinical development.Jet lag typically strikes when a traveler crosses three
times zones or more in quick order, leaving the body's internal clock running to the timetable at home
The chief complaint after touching down is often overwhelming fatigue during the day or merciless insomnia at night
The fallout can be worse heading east, because traveling in that direction effectively reverses the normal day-and-night cycle.Unsettling as
they are, those ailments barely do jet lag justice.Each of the billions of cells in the human body has its own clock, and vital processes
including heart function, food absorption and metabolism are all disrupted when organs get out of step, said Carrie Partch, a biochemist and
associate professor at the University of California Santa Cruz who has studied the circadian rhythm for 20 years."Jet lag is more than just
an inconvenience," Partch said in an interview
"It's pretty devastating physiologically
If you're a constant traveler, you'll probably put on more weight, you'll probably have cardiovascular challenges and you may have some
behavioral changes."While researchers in this field understand how light enters the brain and adjusts the master clock, they're still
As recently as 2017, scientists won a Nobel prize for discovering molecular mechanisms that control circadian rhythms
Even if the core proteins of a rodent can be manipulated in a laboratory to speed up internal clock adjustment, a fast-acting pill that can
do the same for frequent flyers is a way off, Partch said.Scientists have found exercise and the right food can help synchronize the body to
a new time zone, though research has also repeatedly shown sunlight is the most powerful tool
A University of Boulder Colorado study in 2017 said body-clock adjustment can be rapidly achieved by exposure to natural light
alone.Friday's flight from New York, and another from London later this year, are key tests for Qantas as it prepares to start direct
commercial services from those cities to Sydney as soon as 2022
The airline calls it Project Sunrise
If successful, Qantas says other super-long, non-stop routes from Australia's east coast to South America and Africa might follow.Airbus SE
and Boeing are vying to supply the carrier with new long-range aircraft that can reach the destination with a full load and fuel to spare
Qantas plans to make a decision to press ahead with these flights, or ditch the idea, by the end of 2019.It's not just crossing time zones
General fatigue, poor-quality sleep, as well as the dry and pressurized cabin air exacerbate jet-lag symptoms, said Conrad Moreira, a
medical director at the Travel Doctor-TMVC clinic in Sydney who has worked in the field for more than a decade."I've seen people disoriented
a week after a flight," Moreira said in an interview
He prescribes a range of sleep-inducing drugs, particularly for anxious flyers
They including Stilnox - also known as Ambien - and Xanax
Tablets containing melatonin, naturally produced in the body to promote sleep, can also help, he said.Jet lag has been confounding travelers
There are already at least half a dozen ultra-long flights lasting 17 hours or more, including an Auckland-Doha service by Qatar Airways
Qantas last year started direct services to London from Perth on Australia's western seaboard.Just like all those routes, Qantas's planned
network of longer, clock-busting flights will be prey to rising fuel prices
And beyond that, there's a growing movement to encourage flyers to cut their carbon emissions
Still, the airline's stock has soared about fivefold in five years
Qantas rose 2.9% Tuesday to its highest since August 2018.Addressing the health implications of ultra-long flights is critical for Qantas
It must gain permission from Australia's civil aviation regulator for cabin crew to be on duty longer than 20 hours
The airline also needs a new deal with pilots who will fly the extra-long routes on new aircraft.Managing staff exhaustion from lengthy
trips is an issue for the entire industry
According to IATA's latest fatigue-management manual, some cabin crew can spend almost 21 hours awake on the day of a long-haul flight -
even when their duty period is shorter than 10 hours.Qantas's ultra-long direct flights will be priced squarely at the business traveler,
since they stand to win precious hours on the ground at the destination, said Rico Merkert, professor of transport and supply-chain
management at the University of Sydney's business school."It could be a game changer if they get it right," Merkert said.Get Breaking news,
