If you are one of the millions of people who watched the “Double Rainbow Guy” clip, and wondered how you could get your hands on whatever he was taking, I’ve got bad news.

It turns out that he might have been telling the truth when he said he wasn’t on drugs, the famous meltdown might actually have been a case of Stendhal syndrome.

What is it

Stendhal syndrome (also known as Florence Syndrome), causes sufferers to become overwhelmed by beauty such as a work of art or a natural wonder.

Symptoms can include rapid heartbeat, dizziness, confusion, fainting and even hallucinations.

The condition is named after the earliest recorded victim, Henri-Marie Beyle (a French novelist whose nom de plume was Stendhal), who suffered an attack during a visit to Florence.

Do I have it?

While some psychiatrists question whether the condition really exists, little research haas been done into the syndrome at the moment. It is thought however, that no particular pre-existing condition is required for someone to exhibit signs of Stendhal syndrome, meaning that there’s no way of knowing until you break down in a museum…

Can anything be done?

Though in some rare cases sufferers have been affected seriously enough for them to require treatment in hospital and even antidepressants, most people are fine after a nice sit down.

As we’ve said, little is known about whether one attack makes another more likely at this point, so even if you do one day find yourself doing a “Double Rainbow”, there’s no real reason to believe you’ll freak out every time you see one from then on.
