Överhettad

Överhettad is a Swedish adjective meaning "overheated", derived from the verb överhetta (to overheat) and the noun hetta (heat). It is commonly used both literally to describe excessive temperature in physical systems and figuratively to describe heightened or excessive activity or emotion.

In technical and everyday contexts, överhettad describes engines, electronic components, machinery, and rooms that have reached temperatures above their safe operating range. Causes include inadequate cooling, high ambient temperature, excessive workload, friction, and failures in thermal management. Consequences can range from reduced performance and automatic thermal throttling to permanent damage, fires, or thermal runaway. Preventive measures include ventilation, heat sinks, cooling systems, load reduction, and temperature monitoring.

In medical contexts, överhettad refers to persons experiencing excessive body heat, such as heat exhaustion or heat stroke, often requiring cooling, hydration, and medical attention to prevent organ damage.

Figuratively, överhettad is applied to markets, economies, debates, or atmospheres to indicate unsustainable growth, speculative bubbles, or emotionally charged conditions (e.g., "en överhettad ekonomi" or "ett överhettat samtalsklimat"). The noun form is överhettning, and antonyms include underkyld or sval (cold, cool). The term is widely used in Swedish technical literature, media reporting, and everyday speech to convey both literal thermal excess and metaphorical overintensity.
