A long-haul flight is probably the most common perpetrator in murdering someone's wanderlust. Sitting in a small enclosed space for more than 8 hours can seem like pure torture, especially when you run the risk of finding a noisy flight partner.

Regardless, you should never ruin a new possible adventure just because of a long-haul flight. Follow these simple tips to become an international jet-setter.

1. Drink plenty of water.

Airplanes are dehydrating, which can lead to awful feelings of grogginess and exhaustion. Be sure to regularly drink water throughout the flight to avoid headaches and nausea. If you're worried that you'll be an annoyance to your seat partner due to frequent bathroom trips, purchase an aisle seat.

2. Pack the essentials.

Depending on your airline, you could end up with a small TV screen in front of your seat that is stocked with plenty of movies and television episodes to keep you entertained for days. But in unfortunate cases in which boredom strikes, pack a small survival kit that includes a pair of headphones, a tablet, or a good book.

3. Avoid junk food.

The sugary candy and salty grub that you usually find within an airport can wreak havoc not only on your stomach but also your wallet's well-being. If you feel peckish, snack on fresh fruit or a trail mix made up of nuts and seeds. Nutritionally-dense foods will help keep you energized and satisfied instead of feeling bloated and sluggish. Besides, turbulence and fast food do not make a pretty picture.

4. Moisturize.

As previously stated, airplanes are dehydrating and you must protect your skin throughout the long-haul flight. Keep a few travel-sized moisturizers in your carry-on in case your skin starts to flake. If you want to feel refreshed and absolutely revitalized, add a sheet mask to the mix.

5. Wear comfortable clothing.

In addition to being a dehydrating vacuum, an airplane can be as cold as a meat locker. Your airline would usually provide a scratchy blanket and mini-pillow for long flights, so you might find yourself frozen. Wear clothing that is comfortable and warm enough to sleep in, but versatile to get through TSA in a snatch.

6. Sleep.

Long-haul flights usually signify new time zones and jet-lag, so getting enough rest is essential prior to starting a new adventure. The pilot usually shuts off the cabin's main lights after a meal is served and you'll be offered tea or water before bedtime.

7. Stretch and walk around.

It's important to get up and stretch every once in a while to clear your head and keep the blood flowing. Being crammed for so long can make you tense and stiff, which is why a stroll along the cabin's aisle is effective in relieving aches and pains.
