Get ahead of jet lag

Long haul travel can take its toll on your body – changes in time zones, the effect of altitude on your body and the environment on the plane (recycled air, restricted space, rich food at unusual times) can all combine to make you feel like a bit of a zombie for a few days after you land.

Your internal body clock cannot travel as fast as a jet engine, and it resets to a new time zone more gradually. A regular sleep-wake cycle is important to maintain immunity and many bodily functions, which can explain why you can be susceptible to illness after travel. Circadian misalignment — sleeping, working, eating, and being awake at the wrong times according to your body’s internal clock — is what creates the ‘lag.’

Research has also suggested that jet lag might have an effect on your memory and cognitive function for a time after you travel. Increased levels of the hormone cortisol have been shown to negatively affect cognitive functioning, and while on one hand travel is exhilarating and stimulating, on another there can be underlying stress as well (unfamiliar surroundings, new languages, connections to other travel), which produces cortisol.

The good news when it comes to jet lag, getting your body back on track (and on time) as soon as possible after travelling is the best strategy to protect yourself from brain fog and sleep disruptions.

All travellers feel better and get more out of their trip if they feel well-rested when they reach their final destination, whether they’re traveling for business or pleasure.

Happy travels!
