COLD COMFORT

Claire’s* legs ache with cold as she pushes forwards into the messy grey sea, grey sand stretching behind her, grey sky above. She braces herself against each incoming wave, the wind whipping at her exposed skin. Her local beach, Scheveningen, on the western coast of the Netherlands, is a wide expanse of sand running uninterrupted beside the North Sea. It’s March, and the sea temperature is about 6°C.

In the water, Claire’s skin temperature drops instantly, and after a few minutes, her muscles start to cool, stiffening like chewing gum. Her swim is short, and warming up takes hours, but she’s elated to be there. “We were jumping around, shrieking like schoolgirls,” she says, remembering her first taste of cold water swimming. Claire needed the boost, as three months before, after suffering a personal trauma, she’d sunk into severe depression.

In the UK, where Claire is originally from, researchers are looking into the scientific benefits of cold water swimming for people who are experiencing mental health problems, such as anxiety and depression. They’re dipping volunteers into troughs of frigid water in labs, and leading groups into the water beside Brighton Pier. And they’re discovering that cold water immersion can prime you, mentally and physically, to better deal with any stress that might come your way.

HOW DIFFICULT WOULD IT BE TO FLY THROUGH THE ASTEROID BELT?

In the 1980 film Star Wars: The Empire Strikes Back, Han Solo and friends try to escape pursuing imperial forces by flying through an asteroid field. Droid C-3PO remarks, \"the odds of successfully navigating an asteroid field is approximately 3,720 to 1\". The scene depicts a chaotic, dense field of rocks swirling and spinning through space. This scenario has been played out many times in the cinema.

HOW CAN I BE MORE PERSUASIVE?

Most of us like to think we're rational people. If someone shows us evidence that we're wrong, we'll change our minds, right? Well, not necessarily, because it's not always that simple. Being wrong feels uncomfortable and sometimes threatening. That's why changing someone's mind is often much harder than it seems.
