What does sensitize mean?
Sensitize means to make someone aware of an issue or to make something more responsive to particular conditions. In its most common social use, the word describes efforts to help people recognize problems they might otherwise ignore, such as discrimination, environmental damage, or safety risks. It can imply a deliberate process of education and increased awareness rather than a momentary change of opinion. “Sensitize” also has technical meanings involving making a material, sensor, or system increasingly responsive to light, temperature, pressure, or another stimulus. The word is common in North American English, while British English usually uses the spelling “sensitise.” Its usefulness lies in capturing the idea of shifting perception: sensitizing people changes what they notice, and sensitizing a mechanism changes how it responds.
