Jet lag 'cures' aplenty, but none that work for all

New York

RITA Gunther McGrath, a Columbia Business School professor, is one of those business travellers who does not care about delays, cancellations or navigating a new location. What does concern her is the seeming inability to conquer jet lag, and the accompanying symptoms that leave her groggy, unfocused and feeling, she says, "like a dishrag".

"Jet lag has always been an issue for me," says Prof McGrath, who has been a business traveller for more than two decades and has dealt with itineraries that take her from New York to New Zealand to Helsinki to Hong Kong all within a matter of days.
