Soil That Causes Elephantiasis

Some tropical soils can cause severe leg swelling if you walk on them barefoot. This condition, known as podoconiosis, occurs when tiny mineral particles from volcanic soil penetrate the skin and trigger an immune reaction.

Unlike many tropical diseases caused by parasites or insects, this one is strictly environmental. Long-term contact with specific irritant soils triggers a buildup in the lymphatic system, leading to painful disfigurement. Fortunately, the solution is remarkably simple: wearing shoes acts as a complete barrier to the mineral shards. By protecting the feet, entire communities can avoid this lifelong disability.
