Keeping yourself active and enjoying some much needed sunshine helps you to adjust your body clock system quicker.
Steve Simpson, University of Sydney professor, said: "The fundamental basis of jet lag is the disruption of your body clock system. We have what's known as a circadian clock system that organises everything about us. It's a very sophisticated clock system which resides in every cell and organ in our bodies and is controlled by a master control clock in our brain ... What happens when you go on a long haul flight is you leap from one time zone to another more quickly than your clock can reset itself. Since it can only shift an hour to an hour and a half per day, it leaves you 'messed up.'"
And Pieter Elbers, the CEO of KLM Royal Dutch Airlines, agrees with this.
He added: "Well, beating jet lag for me is an early morning run. So, wherever I go, I wake up early, I do my run, and that's, for me, the way to beat the jet lag. Well, being in New York now it's - there's no better place to run in the morning than in Central Park. So that's what I do."
Elbers - who flies weekly - also revealed the secret to smart packing.
He told Business Insider: "Everything is in a fixed place. Everything is packed in the same way. I'm boarding an aircraft about every other week, so I want to make sure I don't forget anything. I need everything to be done in the very same way. I know where everything is packed, I know the sequence of packing it. So yes, I do it in the same very structured way."
