Antarctica’s desolate midwinter drives explorers to madness

As Midwinter Day approaches in Antarctica — the longest and darkest day of the year — those spending the winter on the frozen continent will follow a tradition dating back more than a century to the earliest days of Antarctic exploration: They will celebrate having made it through the growing darkness and into a time when they know the Sun is on its way back.

The experience of spending a winter in Antarctica can be harrowing, even when living with modern conveniences such as hot running water and heated buildings. At the beginning of the current winter season, in March 2025, global news outlets reported that workers at the South African research station, SANAE IV, were “rocked” when one worker allegedly threatened and assaulted other members of the station's nine-person winter crew. Psychologists intervened – remotely – and order was apparently restored.

The desolate and isolated environment of Antarctica can be hard on its inhabitants. As a historian of Antarctica, the events at SANAE IV represent a continuation of perceptions – and realities – that Antarctic environments can trigger deeply disturbing behaviour and even drive people to madness.

The very earliest examples of Antarctic literature depict the continent affecting both mind and body. In 1797, for instance, more than two decades before the continent was first sighted by Europeans, the English poet Samuel Taylor Coleridge wrote “The Rime of the Ancient Mariner.” It tells a tale of a ship blown by storms into an endless maze of Antarctic ice, which they escape by following an albatross. For unexplained reasons, one man killed the albatross and faced a lifetime's torment for doing so.

Stories of Antarctic “madness” have some basis in history. A long-told anecdote in modern Antarctic circles is of a man who stabbed, perhaps fatally, a colleague over a game of chess at Russia's Vostok station in 1959.

More certain were reports in 2018, when Sergey Savitsky stabbed Oleg Beloguzov at the Russian Bellingshausen research station over Beloguzov’s tendency to reveal the endings of books that Savitsky was reading.
