Theme parks are no strangers to unusual rules, but one moment in UK theme park history still raises eyebrows years later. During a particularly warm spell, Thorpe Park made headlines after introducing an unexpected request for rollercoaster riders — keep your arms down.

Not because of safety. Not because of loose articles.

But because of… body odour.

Yes, really.

A Hot Summer — And An Unexpected Complaint

The story dates back to a previous UK heatwave when soaring temperatures combined with packed queues created the perfect environment for guest discomfort. According to park officials, customer feedback began highlighting an unusual issue: body odour experienced during rides.

Mike Vallis, a director at Thorpe Park at the time, explained that the park had received multiple complaints during the hot spell. Guests reported that raised arms on rollercoasters were sometimes leading to less-than-pleasant sensory experiences for fellow riders.

It was a problem few parks had publicly acknowledged before — but one Thorpe Park decided to tackle head-on.

Why Raised Arms Became the Focus

Rollercoasters are designed to encourage excitement, and for many guests that means throwing their hands into the air during drops, launches, and inversions. However, park management noted a physiological factor at play.

When people experience adrenaline — especially in hot weather — sweating naturally increases. Combine this with close seating arrangements on rollercoasters, and the result can be unavoidable proximity to other riders.

Vallis explained that the human body’s reaction to fear and thrill often involves perspiration, meaning rides themselves could unintentionally amplify the issue.

The park’s solution? A polite request:

Guests were asked to keep their arms down during the hot spell where possible.

Publicity Stunt — Or Genuine Guest Care?

As with many unusual theme park stories, speculation quickly followed. Some suggested the policy was a publicity stunt designed to generate headlines.

Thorpe Park’s spokesperson pushed back on that narrative, stating that the decision was rooted in genuine guest feedback and experience standards.

Whether marketing opportunity or operational response, the story undeniably captured public attention — and remains one of the more quirky moments in UK theme park history.
