Cognitive load in UX design refers to users’ mental effort to interact with a product. When users face too much information or complex navigation, their cognitive load increases, frustrating the experience. Good UX design minimizes cognitive load by keeping interfaces simple, intuitive, and focused. This means using clear language, logical layouts, and familiar patterns. By reducing cognitive load, we help users achieve their goals easily and enjoyably, leading to a better overall experience.
