Ways to Relief Jet Lag and Maximize Your Adventure


You've arrived in the sun-drenched Mediterranean, poised for the holiday of your dreams. Yet, instead of a burst of excitement, you're weighed down by drowsiness and a clouded mind. Don't allow jet lag symptoms to dampen the spirit of your retreat! This guide will unveil tested tactics to defeat travel weariness and maximize your journey.


first, let's see the definition of Jet lag.

Jet lag is a temporary sleep disorder that occurs when you travel across multiple time zones rapidly, typically by airplane. It happens because your body's internal clock (circadian rhythm) remains synchronized to your original time zone rather than adjusting immediately to your new location.

Here's a more detailed breakdown:

Scientific name: Desynchronosis or Flight Fatigue

Key elements of the definition:

  1. Time zone mismatch: Your internal body clock is out of sync with the local time at your destination

  2. Rapid travel: The quick crossing of time zones doesn't allow your body to adjust gradually

  3. Direction matters:

    • Traveling east usually causes worse jet lag than traveling west

    • Rule of thumb: it typically takes one day per time zone crossed to fully adjust

Common symptoms of Jet lag:

  • Difficulty sleeping at night or staying awake during the day

  • Impaired physical and mental performance

  • Gastrointestinal problems

  • Mild disorientation

  • Headaches

  • General fatigue
