It’s fair to say that the Queen is one of the world’s most experienced travelers.
So if her majesty has a trick for dealing with jet lag, we should all be paying attention.
According to The Independent, she relies on homeopathic medicines and barley sugar – which can be bought from the high street for under $2, or around 1 pound — to get her adjusted to different time zones.
Barley sugar, taken in boiled sweet form, isn’t a magic cure all, but it could help to kick-start the Queen’s metabolism when she’s abroad and get her hungry at the right times of day.
As general practitioner Nick Knight told The Telegraph, "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.
"What the Queen is doing by having barley sugar is essentially using her body’s sugar metabolic pathways to help adjust her body clock."
"Essentially, the same should happen if you were to have your breakfast, lunch and dinner at times that match your destination before you get there, regardless of whether you’re hungry or not," Knight added.
