Queen Elizabeth II is still a jet setter even at the age of 91. Her social calendar includes events throughout the Commonwealth, while also making visits to fellow EU countries. (Fun fact: the Queen doesn’t require a passport when traveling abroad). It’s also not an easy task for Her Majesty to fly. Every minute of a trip is planned out well ahead of time with practice runs using a Travelling Yeoman who is in charge of everything from packing bags to moving equipment (the Queen’s longtime Traveling Yeoman was suspended after he showed up to the palace drunk in 2011).
While everything seems to be controlled when it comes to traveling with the Queen, one thing that no aide can help is jet lag. The Telegraph recently revealed that all it takes is a ten-dollar candy to help her get over the worst of a time change. A lozenge that contains barley sugar apparently is just enough of an energy boost.
“Carrying out your daily habits like eating and sleeping in line with your new destination's time zone - both en-route and on arrival - helps re-synchronise our body clock to our new environment,” Dr. Nick Knight told the Telegraph. “What the Queen is doing by having barley sugar is essentially using her body’s sugar metabolic pathways to help adjust her body clock.”
Apparently the Queen isn’t the only one who uses this trick even Amazon sells Simpkins Barley Sugar Travel Sweets.
