Polar T3 Syndrome

Polar T₃ syndrome is a condition found in polar explorers, caused by a decrease in levels of the thyroid hormone T₃. Its effects include forgetfulness, cognitive impairment and mood disturbances. It can exhibit itself in a fugue state known as the Antarctic stare.

It is regarded as one of the contributory causes of winter-over syndrome.
