Shivering - nerve impulses are sent by the hypothalamus to the skeletal muscles to bring about rapid contractions that generate heat. Shivering therefore helps raise the body temperature. Increase in metabolic rate - the liver produces extra heat in order to raise the temperature of the body.

∙ 13y agoShivering is the body's way of attempting to generate heat. It is the rapid movement of muscles expending energy to generate heat and warm the body.
That's all there is to it! Shivering can also be a reaction to fever or to post-operative stress.

∙ 9y agoShivering helps to raise your body temperature a couple of different ways:
- · Shivering requires your muscles to contract and release rapidly. Your muscles use stored energy to do the contraction, and in the process the stored energy converts to thermal energy. Your muscle cells also do more cellular respiration to get more energy, producing even more thermal energy. The thermal energy spreads through your tissues on its way to the air around you, warming your body in the process.
- · Shivering also triggers your body to produce a hormone called irisin, that activates your brown fat. When brown fat is metabolically active, it breaks down stored fats and releases their energy as thermal energy.

Is sweating a reflex triggered to warm your body?
No. Sweating is used to cool the body; shivering is used for warming.
What is the process of sweating and shivering called?
Sweating and shivering
Why do you shiver when we're not cold?
Shivering is one of the methods that the human body uses to warm itself. It is a neurological reaction, that the body executes when it gets too cold. Joggers are familiar with the concept of moving to stay warm; they run in the coldest of weather and manage to stay warm. Basic physics dictate that energy taken from a storage source (like our fat) and changed to another form of energy (your body movements), results in yet another form of energy - heat. So when your muscles start moving back and fourth rapidly, they make heat, which helps warm the body in the cold. Some people have a different tolerance for cold, and in fact those who shiver easier, can withstand colder temperatures. Specific tolerances can change as we adapt over long term exposure, which is why all those Florida natives look at you funny when you wear your shorts down there in January, they have just adapted to the warm temperatures. Shivering is a sign that hypothermia is setting in as well, it's a very early sign, but uncontrollable shivering should be taken seriously. Here's a link to more information on hypothermia it's from Boston but I think they have hypothermia there too:
What keeps body temperature constant?
The hypothalamus is the gland that is responsible for ensuring that the human body is at the proper temperature. If the body falls out of the normal temperature range, there are multiple mechanisms the body uses to return to normal. Among them are: Shivering. If your body temp is too low, shivering causes your muscles to generate more heat to warm up. Blood flow. If you are too warm, your body opens up all the capillaries and increases blood flow to the skin, which allows heat to be taken away from the body and into your environment. If you are too cold, your body shuts off capillary beds in order to retain as much heat as possible at the core, to keep your most vital organs at the proper temperature. Sweat. Sweat on your skin helps carry away heat from your body, in combination with blood flow discussed earlier.
Sweating and shivering are examples of?
Feedback mechanism
What is the function of shivering?
Shivering is an involuntary muscular response from the body, triggered by cold. The "shivering" muscles are trying to internally generate heat, to help keep you warm.
Why do you keep shivering when your body is warm?
Not very effectively. Shivering is a last-ditch attempt by the body to generate heat in it's own muscles to try and ward off increasing cold, but the operative words are "last ditch" - it just doesn't help much if one is really chilled.
How do you keep your infant bird warm if it already has a heating pad and he is shivering?
If it is a wild bird, it may be shivering due to too much stimulation. Call and find someone experienced in fostering young animals.
Why is energy required for shivering?
Because shivering is just all your muscles working (in order to get warm)
What reflex is triggered to warm your body?
Shivering
Shivering when you are cold actually warms you up?
Yes, infact it does. When you shiver, your body recoginzes that you are cold and conserves heat to keep you warm.
When you feel cold what does your body do to keep us warm?
ONE of the things is to shiver. Shivering is involuntary muscle movement that creates heat.
What is the scientific name for shivering to warm up?
thermogenesis
Why do you become sleepy when you come inside from the cold?
Likely to be because your body and muscles are working hard to keep you warm whilst you are in the cold ...(i.e. shivering) so when you actually warm up and your muscles can rest you feel tired as you have used a considerable amount of energy to keep warm
If you shiver on a cold winter night are you shivering from the cold or heat?
I believe your body is responding to the cold by shivering to warm you up.
Why do you shiver you are cold?
shivering is said to warm your body when cold.
Is shivering when you get cold is an example of metabolism?
shivering helps to protect warm-blooded animals and survive when exposed to cold .it increases metabolism.
