Shivering

Definition and stakes

John Augustine Waller,  A Treatise on the Incubus, or Night-Mare…

“ I have always observed in my own case, as well as in all those I have had the opportunity of investigating, that this kind of affection is universally accompanied with a sensation called shivering; not precisely of that kind which accompanies the paroxysm of ague, but that momentary sensation of shivering which people are apt to feel on hearing any tale of horror related, or frequently indeed, without any evident cause whatever. It is a vulgar opinion, that this shivering takes place whenever any one is walking over the future grave of the person who feels it. ”

Bulchevy's Book of English Verse

“ A sightless heaven, a shaven land.
Her shivering Spring feign'd fast asleep,
The bitten buds dared not unfold:
We raced on roads and ice to keep
Thought of the girl we love from cold.
But now the North wind ceases,
The warm South-west awakes,
The heavens are out in fleeces,
And earth's green banner shakes.

Ernest G. Martin,  Physiology: The Science of the Body

“ It is reflex in the strict sense, that is to say, the stimulation of cold on the skin arouses nervous disturbances which pass to the muscles in various parts of the body and set them into the violent movements which we call shivering. The functional metabolism of shivering is much greater than we might at first suppose, and the production of heat is correspondingly rapid. In fact, if one who feels inclined to shiver encourages it instead of attempting to keep from doing it, he will very quickly produce enough heat within his body so that he will no longer have a disposition to shiver. ”
