What does sanitarium mean?
A sanitarium is an institution or residential facility where people receive medical care, rest, and treatment while recovering from illness. The term became especially prominent in the nineteenth and twentieth centuries as tuberculosis treatment often required prolonged isolation, fresh air, rest, and carefully controlled nutrition. Many sanitariums were built in rural or mountainous locations for this purpose. With the development of effective tuberculosis medicines, their role declined, although some continued serving other kinds of patients. Today, the word often appears in historical writing, descriptions of old institutional buildings, and accounts of life before modern treatments. Although it can describe a medical establishment generally, its strongest association is with tuberculosis sanatoria. The alternate spelling sanatorium is also widely established and may be encountered more often in British English.
