Body & Senses
Why do we shiver when cold?
Puschel feels chilly. Flauschi explores why muscles can shiver in the cold.
The short answer
When you are cold, your muscles can work quickly without you choosing to move them: you shiver. This produces heat. Shivering is a signal to find warmth and shelter.
An imagined Wusel scene
Puschel and Flauschi investigate
At the end of their outing, Flauschi notices Puschel shivering. They tell Lumi and go with her somewhere warm. Only then do they talk about shivering. Puschel does not have to prove how long he can stay cold.
Try explaining it
What produces heat when you shiver?
Choose a), b) or c), then explain your choice.
- a)The sound of chattering teeth rather than muscle movement.
- b)Rapid muscle activity.
- c)Resting muscles doing no extra work.
Show the explanation
Correct: b): Rapid muscle activity.

Understand step by step
How it works – simply explained
Heat is lost
In cold surroundings the body may lose too much heat. It tries to preserve its inner temperature.
Muscles produce heat
Shivering repeatedly tightens and relaxes muscles. This work releases heat. It is involuntary: you do not plan each muscle action.
Shivering is not enough
Seek warmth, shelter and help. Dry warm clothes may matter. Prolonged cold is not a child experiment; less shivering does not reliably prove recovery.
The key points again
Discovery 1
The body tries to keep its temperature within a suitable range.

Discovery 2
Shivering involves quick, involuntary muscle contractions that release heat.
Discovery 3
Shivering is a reason to seek warmth and shelter, not a challenge to stay cold longer.
