Cotton | Can’t Sleep? Learn About the Fabric of Civilization

The I Can’t Sleep podcast explores the history and science of cotton, the most widely used natural fiber in clothing today. The episode traces the plant’s journey from prehistoric cultivation in the Americas, Africa, and Asia to its role as a global commodity that shaped economies, technology, and daily life. Current world production sits at about 25 million tons annually, with India as the largest producer and the United States as the largest exporter. But the story of cotton is far older and more intricate than modern statistics suggest.

The Deep Origins and Early Domestication of Cotton

Cotton is a soft, fluffy staple fiber that grows in a protective case around the seeds of plants in the genus Gossypium, part of the mallow family. The fiber is almost pure cellulose, with minor amounts of waxes, fats, pectins, and water. The plant is a shrub native to tropical and subtropical regions worldwide, with the greatest diversity of wild species found in Mexico, followed by Australia and Africa.
