Shauder

Shauder refers to a phenomenon involving a sudden, involuntary shiver or tremor, often accompanied by a feeling of unease or goosebumps. This sensation can be triggered by various stimuli, including cold temperatures, emotional responses like fear or excitement, or even the perception of something unpleasant. In some contexts, it can be a physiological reaction to a rapid change in body temperature or a response to a startling stimulus. Psychologically, a shauder might be linked to the activation of the sympathetic nervous system, which prepares the body for a "fight or flight" response. While often a fleeting and harmless experience, persistent or extreme shauders could, in rare cases, be indicative of underlying medical conditions, though this is not the typical association. The word itself is not widely recognized in formal scientific or medical literature, often being used in more colloquial or descriptive language to convey the subjective experience of shivering or trembling.
