6 Diseases Named After the Job That Gave Them to You

Six diseases whose names reveal the dangerous jobs that caused them — Mad Hatter Disease, Telegraphist’s Cramp, Grinder’s Asthma, Painter’s Colic, Caisson Disease, and Chimney Sweeps’ Carcinoma. Before scientists could identify the chemicals, pressures, dust, or toxins behind these illnesses, doctors noticed something much simpler: the same kinds of workers kept getting sick. So the occupation became part of the diagnosis. In this video, we go inside the workshops, factories, construction sites, and cramped working conditions where these diseases first appeared — from mercury-filled hat workshops and dusty grinding floors to deep underwater caissons and the soot-covered chimneys of 18th-century London. Some of these workers were exposed to dangers they couldn't see. Others were using materials that were actually considered perfectly safe at the time. And in several cases, the warning signs were there long before anyone was willing to listen. But these aren't just strange diseases with old-fashioned names. They helped reveal one of the most important ideas in medical history: sometimes the job itself is the cause of the disease. By the final story, we'll reach the moment when a London surgeon connected a specific occupation to a specific cancer — helping lay the groundwork for the idea of occupational disease that still shapes workplace safety today.
