To increase your body temperature.
rise
Shiver. The muscle action will raise the temperature.
Arctic foxes can survive in temperatures as low as -58 degrees Fahrenheit. About -15 degrees Celsius.
Ferrets shiver becauseUpon awakening. when they sleep, their body temperatures lower, and they shiver or shake to warm upWhen they are excitedSomething may have frightened them, like a loud noiseThey are cold.
The Arctic fox lives in some of the most frigid extremes on the planet but does not start to shiver until the temperature drops to −70 °C (−94 °F).
Body Temperature is at a constant 37.5 degrees celsius because it is the optimum temperature for Enzymes to operate at. It is kept this temperature by a part of the brain called the Thermologygatory Centre. The body can do numerous things to keep in Thermal energy or release it, your body can shiver and use kinetic energy from that and transfer it to thermal energy. Your body can also dilate your blood vessels and move blood capillarys closer and furthur away from the skin, hense why your checks appear red when exercising.
Ferret can tolerate cold temperatures very well, they normally don't get cold. Ideal temperature for a ferret is about 60 - 70 degrees Fahrenheit. When a ferret sleeps, it's body naturally lowers their temperature, so upon waking they will shiver to warm up, but it doesn't mean that it's cold. Also a ferret will shiver when frightened. They have poorly developed sweat glands and cannot tolerate temperatures above 85 degrees Fahrenheit.
Well it depends on what kind of person you are...if you live in florida, its probably very comfortable. In Alaska its very warm...
not necessarily- temperature below the bacteria functioning temperature will already retard them- just anywhere lower than its average temp. Take yourself as a comparison. If you were in a colder temperature than your body temperature (and normally a lot lower, will the temp make you shiver and slower you down, ven your thinking
Yes by telling it to sweat if hot and shiver if cold.
Only when you shiver - "useless" work to produce heat.
