A form of culture shock -

Paris syndrome is an extreme form of culture shock and homesickness. But while you should expect some culture shock when you travel, the biggest forms are usually reserved for people who study and settle in a new country for months at a time.

When was the term first used? -

In 1986, Franco-Japanese psychiatrist Hiroaki Ota first used the term "Paris syndrome" to describe this transient psychological disorder.

It has four factors -

This unusual condition is supposedly brought on by four factors. And it has been noted mainly in Japanese tourists.

The first factor -

The first condition is the language barrier between the vast majority of the visiting Japanese and their French hosts.

The second factor -

Tied to the first factor are the differences in manners, which can be extremely upsetting. These include decreased levels of formality, frequent fluctuations in mood or tone, and incomprehensible humor.

The third factor -

Thirdly, there's the physical exhaustion. Whether travelers are in Paris for business or pleasure, they'll pack their schedules so much it gets overwhelming.

The fourth factor -

Finally, there's the jet lag, which is especially true for visitors from Japan. Add that to the mix and it's no wonder why someone would be stressed out.

But why Paris? -

One might wonder: isn't this equally the case for Japanese holidaymakers in other major European or American cities? Surely Berlin and New York must be as destabilizing?

No picture-postcard scenes -

The theory is that the image of an elegant and sophisticated Paris creates extremely high expectations. The sight of dirty sneakers instead of fancy heels sends these visitors over the edge.

Paris in the media -

Many people want to visit Paris because of the way it's portrayed in the media. But the reality is that Paris is a real city, and not a romantic comedy like 'Amélie' (2001).

The reality of big cities -

Just like in every densely populated city, Paris also deals with rats, trash, pickpockets, and various unpleasant aromas. All of which are terribly unromantic.

Is Paris syndrome actually real? -

Although it's a rare syndrome, there have been reported cases. In 2006, about a dozen tourists suffered severe symptoms that needed medical attention.

Reported cases -

In that same year, the Japanese embassy repatriated at least four visitors who had severe cases, including two women who believed their hotel room was bugged.

What are the symptoms of Paris syndrome? -

The symptoms are very similar to anxiety and psychosis. Victims have typically experienced hallucinations, dizziness, sweating, feelings of persecution, and even vomiting.

How can Paris syndrome be prevented? -

Even if Paris syndrome sounds scary, Paris is still a wonderful city. Tourists should simply remember that, like any city, it will have its pros and cons.

Keep it realistic -

Embrace the chance to visit a new city and the beauty it has to offer. Also, by keeping your expectations realistic, you’re sure to like Paris more than you would imagine.

© Shutterstock

Expectations -

Don't forget, Paris is one of the most visited cities in the world, and for good reason. Expect a lot of visitors in museums, like the Louvre.

Not the best close up -

And while you might dream of seeing the 'Mona Lisa' up close, you're not the only one. Expect a big line to see that famous smile.

© Shutterstock

It is, after all, a big city -

The truth is that you won't be alone near the Eiffel Tower. So don't expect to get a picture without any tourists behind you.

© Shutterstock

Join the crowd -

If you're there during the warmer months, you'll likely find a bunch of people laying on the grass. Instead of getting annoyed by it, join the crowd!

© Shutterstock

Sometimes it can be picture-perfect -

You will find that Paris can be picture-perfect. Just imagine seeing famous monuments like the Sacré Coeur and the Arc de Triomphe for the first time. It's an unforgettable feeling.

© Shutterstock

You won't be alone -

But, of course, you won't be alone. And you'll notice that's the case with any major city—especially if it attracts a lot of tourists.

© Shutterstock

A romantic ride -

The Paris metro is the fastest and smoothest way of getting around Paris. And if you're lucky, you might find an empty wagon.

© Shutterstock

Rush hour is real -

But people actually live in Paris, so be sure to avoid taking any public transport during rush hour. The good thing with central Paris is that you can walk around to most places. Do that instead, or hop on a boat tour on the Seine river.

Clean streets? -

Most films set in Paris have painted an image of a clean city. However, many tourists have been shocked with how dirty it actually is.

© Shutterstock

But not always -

The reality of everyday Paris is often at odds with the postcard version. You'll definitely experience urine-soaked streets and tons of cigarette butts.

© Shutterstock

Oh the romance -

Often dubbed as the city of love and romance, you might notice that it isn't all that romantic when you leave the astonishing monuments and picturesque streets behind.

© Shutterstock

It isn't that romantic -

With the rush of daily life, the romantic image of Paris might fade away. But that doesn't mean you won't find French romance!
