How to reduce jet lag

You arrive at your destination after a long flight and, even though it’s daytime, your body insists it’s time to sleep. Or the other way around: it’s night and you’re completely awake. That mismatch is jet lag, the enemy of every traveler who crosses several time zones. The good news: it can be eased with a few simple tricks.

What jet lag is and why it happens

Our body has an internal clock (the circadian rhythm) that regulates sleep, hunger, and energy over 24 hours, synced with the sunlight of our usual location. When you travel quickly across several time zones, that clock stays “stuck” on the origin’s time, while the destination has a completely different one.

The result is jet lag: a time gap between your internal clock and local time. The more time zones you cross, the worse it usually is.

The typical symptoms

Jet lag usually causes, according to the Mayo Clinic:

• Insomnia at night or excessive sleepiness during the day.
• Tiredness and lack of energy.
• Difficulty concentrating.
• Digestive discomfort or loss of appetite.
• Irritability and low mood.

East vs. west: it’s not the same

An interesting detail: direction matters. In general, traveling east (moving the clock forward, like from America to Europe) is usually harder than west (moving it back). It’s easier for the body to “lengthen” the day than to shorten it.

The key: light

The most powerful factor for resetting your internal clock is natural light. Exposing yourself to the sun at the right time helps your body understand the new hour:

• Traveling east, seek light in the morning at the destination.
• Traveling west, seek light in the afternoon.

Going outside in daylight is one of the most effective ways to speed up adaptation.

Tricks that help

Besides light, other strategies reduce jet lag:

• Adjust your schedule before traveling: a few days ahead, gradually shift your sleep hours toward the destination’s time.
• Adopt local time on arrival: eat and sleep according to the new schedule, even if it’s hard. Avoid long naps the first day.
• Hydrate well: drink water and avoid excess alcohol and caffeine, which worsen rest.
• Sleep on the plane if you fly at night toward the destination; stay awake if it’s daytime there.
• Melatonin can help in some cases (check with a professional first).

Adapt and enjoy the trip

Jet lag is the price of being able to cross the planet in hours, but it doesn’t have to ruin your trip. With a little preparation, plenty of natural light, good hydration, and patience, your internal clock adjusts within a few days. Follow these tricks and you’ll be able to enjoy your destination sooner, without tiredness stealing your first days.
