Shivering when it's not cold can occur due to various factors, including emotional responses like fear or anxiety, which trigger the body's fight-or-flight response, leading to muscle contractions. It can also be a reaction to stress, excitement, or even certain medical conditions. Additionally, shivering may be a way for the body to generate heat when it feels uncomfortably cool, even if the ambient temperature is not low.

Lizards do not shiver like mammals do. Instead, they may bask in the sun to raise their body temperature or seek shelter to regulate their temperature. They rely on behavioral adjustments rather than shivering to maintain their body temperature.
