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.
Shivering. One method to raise temperature is through shivering. It produces heat because the conversion of the chemical energy of ATP into kinetic energy causes almost all of the energy to show up as heat. Shivering is the process by which the body temperature of hibernating mammals (such as some bats and ground squirrels) is raised as these ...

Can shivering cause a fever?
A shiver is caused by your muscles tightening and relaxing in rapid succession. This involuntary muscle movement is your body’s natural response to getting colder and trying to warm up....
- Fever. Share on Pinterest. A fever may cause shivering. Other than being cold, the most common cause of shivering is fever, which doctors define as a body temperature higher than 100°F.
- Psychogenic movement disorders. For some people, stress or mental health factors can cause shivering and other involuntary movements. This usually occurs due to a psychogenic movement disorder, which can affect any part of the body.
- Postanesthetic shivering. Share on Pinterest. A person may shiver when recovering from an anesthetic. Shivering can occur when a person regains consciousness after a general anesthetic.
- Fear, excitement, or stress. Strong emotions can cause a person to shake or shiver. This is often due to a surge of adrenaline in the body. Adrenaline is a hormone that triggers the body’s fight-or-flight response.
Oct 30, 2018 · Shivering is typically characterized in terms of two properties: the threshold central temperature for shivering defined as the maximum central temperature for which shivering occurs at a particular mean skin temperature and the sensitivity which defines the rate of increase of metabolic rate with decreasing central temperature.
May 22, 2017 · Although shivering had commonly been measured as a metabolic outcome measure, considerable research is still needed to clearly identify the neuroanatomical structures and circuits that initiate and modulate shivering and drives the shivering patterns (continuous and burst shivering).
