Detailed explanation-1: -Shivering (also called shuddering) is a bodily function in response to cold and extreme fear in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy.

Detailed explanation-2: -Shivering is an involuntary somatic motor response that occurs in skeletal muscles to produce heat during exposure to cold environments or during the development of fever.

Detailed explanation-3: -Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. Endotherms can alter metabolic heat production to maintain body temperature using both shivering and non-shivering thermogenesis.

Detailed explanation-4: -Shivering is part of the body’s natural response to an illness. When a person shivers, it helps their body temperature rise, which helps fight off a virus or a bacterial infection.
