Why do you shiver when you eat something gross?

Shivering when you eat something gross is a physiological response that can be linked to the body's fight-or-flight reaction. It may occur due to a combination of disgust and discomfort, triggering the nervous system to react. This response can involve involuntary muscle contractions, which manifest as shivering. Additionally, the body might be reacting to a perceived threat to its well-being, leading to a physical reaction.
