Why do we shiver?

Question

Scientific question

Answer 1

Shivering is a response that the body has to temperatures.. externally and internally.   It regulates the body from hypothermia..   sweating and shivering keep the body at the right temps.

Answer 2

Your body needs to keep a core temperature of about 98.6°F (36.9°C). To prevent hypothermia and other consequences of a chilled core, your brain monitors temperature very closely. If the surface of your skin gets too chilly, skin receptors send signals to the brain, which sets into motion a series of warming tricks.

Shivering is one such tactic, in which your muscles contract and expand in speedy bursts. In addition to quaky limbs, your jaw muscles might begin to shiver, making your teeth chatter.

This twitching exercise produces heat, which helps to raise body temperature. It's also your signal to find a toasty haven and a warm drink.

Answer 3

If you are cold, repetitive muscle contraction burns calories, generating heat.

Answer 4

we shiver coz the temperature in body is not same as outside temperature

Answer 5

shiver is shiver

Answer 6

Shivering is a bodily function in response to early hypothermia in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered. Muscle groups around the vital organs begin to shake in small movements in an attempt to create warmth by expending energy. Shivering can also be a response to a fever as a person may feel cold, though their core temperature is already elevated.

Located in the dorsomedial portion of the hypothalamus near the wall of the third ventricle is an area called the primary motor center for shivering. This area is normally inhibited by signals from the heat center in the anterior hypothalamic-preoptic area but is excited by cold signals from the skin and spinal cord. Therefore, this center becomes activated when the body temperature falls even a fraction of a degree below a critical temperature level.

Increased muscular activity results in wasted heat- here the heat is utilized for warmth.

Shivering can also appear after surgery. This is known as post-surgical shivering.

Answer 7

because we shiver to help our body protect from cold

Answer 8

because our blood temp drops drimaticly.

Answer 9

when the outside body temperature is lower our body generate heat by shivering for example shivering our teeth is because of these phenomenom only

Answer 10

We shiver in order to produce heat in the muscles through friction , I guess, !!!
