‘高压’ literally means 'high pressure' and is composed of 高 (gāo, 'high') and 压 (yā, 'pressure'). In its most common usage, it refers to high blood pressure (hypertension), a widespread health condition requiring medical monitoring and lifestyle adjustments. It appears frequently in medical contexts, public health campaigns, and everyday conversations about wellness.

Figuratively, ‘高压’ also describes intense, authoritarian control—such as in workplace management, education, or politics—where rigid expectations and strict enforcement create psychological or social pressure. This extended meaning draws on the physical concept of pressure but applies it metaphorically to human systems. While both senses share the core idea of excessive force or constraint, the health-related usage is far more frequent in daily speech and writing.
