Best Way to Beat Jet Lag During Flights is to Avoid Eating Food While Flying
The suggestion for international travellers comes from a study, which shows that the timing of meals has a much bigger effect on the body clock than previously thought.
Not eating food on long haul flights, then eating on arrival, could cut the time it takes to adjust to a new time zone.
Scientists have known for decades that meal times can affect the body clock, which has a natural period of about 24.2 hours. However, they have always thought that the key factor is light.
In investigating the intricacies of the body's biological rhythms, the research team - led by Patrick Fuller, PhD, HMS Instructor in Neurology - discovered the existence of a 'food-related clock', which can supersede the 'light-based' master clock that serves as the body's primary timekeeper.
The findings help explain how animals adapt their circadian rhythms in order to avoid starvation, and suggest that by adjusting eating schedules, humans too can better cope with changes in time zones and nighttime schedules that leave them feeling groggy and jet-lagged.
The suprachiasmatic nucleus (SCN), a group of cells in the brain's hypothalamus, serves as the body's primary biological clock.
The SCN receives signals about the light-dark cycle through the visual system, and passes that information along to another cell group in the hypothalamus known as the dorsomedial nucleus (DMH).
