For millions of UK holidaymakers, the excitement of a trip abroad can quickly be overshadowed by the debilitating effects of jet lag. Symptoms such as disturbed sleep, daytime fatigue, headaches, and uncomfortable digestive problems are common, often ruining the first few days of a much-anticipated break. While adjusting sleep schedules is a known strategy, nutrition experts highlight that what and how you eat and drink can play a crucial role in minimising its impact and helping your body recalibrate faster.
Jet lag occurs when the body's internal biological clock, normally regulated by environmental cues like daylight, falls out of sync with a new time zone. This internal rhythm typically takes several days to adjust. According to registered dietitian Tara Schmidt, who has experienced severe jet lag on European trips, these initial days can be significantly impacted. One primary recommendation is to align your meal times with the local schedule at your destination as soon as possible. Gradual shifts in meal times, even as small as 15 to 30 minutes, can be started before you travel, making the transition smoother.
Upon arrival, immediately adopt the local eating schedule. If it's morning, have breakfast. A substantial morning meal consistent with the new time zone can aid recovery, as suggested by a 2023 study co-authored by Northwestern University researchers. Throughout the day, continue to eat lunch and dinner at times appropriate for your new location. To prevent stomach discomfort, especially in the early stages of your trip, it's advisable to keep meals smaller. This is particularly important for those with sensitive stomachs or experiencing gastrointestinal issues, as smaller portions are generally easier to tolerate.
Hydration and mindful consumption of certain beverages are also key. Experts strongly recommend avoiding alcohol, which is a significant sleep disruptor and can exacerbate dehydration. While caffeine can be used strategically to combat fatigue, it should not be consumed too late in the day, as it can interfere with sleep. Both alcohol and caffeine can contribute to dehydration, which itself can worsen feelings of fatigue and other jet lag symptoms. Drinking plenty of water before, during, and after your flight is crucial to counteract the dry cabin air and maintain overall hydration.
For UK travellers, ensuring adequate hydration by drinking water consistently is vital. Aim for around eight glasses of water a day, adjusting for factors like local weather and activity levels. If there are any concerns about water safety in your destination, opting for bottled water is a sensible precaution. When your holiday concludes, the advice remains consistent: gradually ease back into your normal eating and sleep routines to help your body re-adjust quickly and minimise any lingering jet lag symptoms upon your return home.
