To prepare for a long journey without suffering the effects of jet lag, it is necessary to adopt a complete strategy before, during and after the flight. By gradually adjusting your sleep pattern, hydrating properly, exposing yourself to natural light upon arrival and respecting local schedules, it is possible to significantly reduce fatigue and jetlag-related sleep disorders. To deepen these tips, this travel blog Offers practical tips and valuable feedback.
What is the jetlag and why does it occur?
Jetlag, or jet lag, is a temporary disruption of the internal biological clock caused by the rapid crossing of several time zones. Our body, accustomed to a sleep-wake-sleep rhythm regulated by natural light, finds itself out of sync. This leads to fatigue, sleep disorders, irritability, concentration difficulties and sometimes digestive disorders.
A trip from Paris to New York, for example, involves a 6-hour shift, which may require several days to adapt. The larger the number of spindles crossed, the more the jetlag will be marked.
Before the trip: preparing your body for change
Adjust your sleep pattern gradually
A few days before departure, it is advisable to shift his bedtime and to get up to get closer to the time zone of the destination. For example, if you are traveling east, try to go to bed and get up earlier by about 30 minutes a day. To the west, do the opposite.
This gentle method allows your biological clock to begin to adapt, thus reducing the shock on arrival.
Avoid stimulants and promote restful sleep
In the week before departure, limit the consumption of caffeine, alcohol and sugar, which disrupt sleep. Promote a relaxing routine: reading, meditation, dim light, and wearing anti-blue light glasses in the evening to stimulate the natural production of melatonin, the sleep hormone.
During the flight: adopt the right reflexes
Set your watch at local time as soon as you board
It helps to get mentally into the new rhythm. If it’s time to sleep at your destination, try to sleep on the plane. To do this, equip yourself with a sleep mask, earplugs or noise-canceling earphones, and a comfortable travel cushion.
Hydrate abundantly
The dry air in the cabin promotes dehydration, which aggravates the fatigue associated with the jetlag. Drink plenty of water and avoid alcohol and caffeine, which increase water loss.
Eat light and healthy
Favor light and balanced meals so as not to overload digestion, which can disturb sleep and general well-being.
After arrival: quickly adapt to the new time zone
Exposure to natural light
Light is the main synchronizer of our biological clock. Spending time outdoors, walking, playing sports during the day helps reset your internal pace.
Respect local timetables
Even if fatigue pushes to take a nap, it is advisable to wait at least two hours before sleeping so as not to delay sleeping at night. Eat, sleep and live according to local time to help your body adapt.
Avoid prolonged naps
A short nap (20-30 minutes) may help, but long naps may delay adaptation.
Additional tips for limiting the jetlag
- Use melatonin: taken in addition, it can help regulate sleep, but should be used with caution and ideally on medical advice.
- Anti Jetlag apps: Apps like Time Shifter offer personalized light exposure and sleep programs to facilitate transition.
- Choosing your flights intelligently: arrive at the end of the day when you travel west, or early in the morning when traveling east, facilitates adaptation.
- Move regularly on the plane: to improve blood circulation and reduce fatigue.
Personal anecdote: how a trip to Tokyo was saved by the preparation
On a trip to Tokyo, the jet lag of 8 hours seemed insurmountable. Following a strict plan: progressive sleep shift before departure, constant hydration, immediate adjustment of the watch at local time, and maximum exposure to natural light, fatigue quickly faded. The first day, despite the temptation of a nap, a long walk in Ueno Park made it possible to synchronize my internal clock well. Result: an adaptation in 3 days instead of the usual 5.
Why is the jetlag more difficult to manage east?
Traveling east forces you to advance your internal clock, which is more difficult than delaying it (like when you travel west). The human body is biologically programmed for a cycle a little longer than 24 hours, so delaying sleep is more natural than advancing it.
Conclusion: the jetlag can be mastered
The jetlag is not inevitable. By adopting upstream preparation, good practices during the flight and a quick adaptation to the destination, it is possible to considerably reduce its effects. Experience proves that a well-thought-out strategy allows you to take full advantage of your trip, from the first day.
