The skin is able to feel the cold because it has cutaneous receptors, which are in charge of transmitting sensations of heat, cold, pain, pressure, etc. to the brain for interpretation. In winter there can be rapid loss of body heat without proper protection and shelter. Cold is the absence of heat. Heat radiates out into the cold and is lost from your body when you are exposed to the cold. The sensation your brain creates from its interpretation of the signals from the cutaneous receptors will be one of a chill or feeling cold. Wearing clothing protects from heat loss, especially thick layers of clothing. Hats are one of the better articles of clothing to keep you warm outside in winter since the head has a rich supply of many blood vessels through which the blood flows close to the surface and, if the heat on the outside is lower than on the inside of your body, the heat will escape.
We shiver to keep us warm during winter. The body core (brain, heart, central nervous system, etc) is very sensitive to low temperatures, so when the temperature drops, the CNS sends out instructions for the muscles to burn fuel (sugar + oxygen) to produce heat. The muscles aren't very bright; they don't know that they could do interesting things like pushups, situps or running. Instead they do the simplest thing, which is simply to twitch ... push, pull, push, pull ... it is this repetitive twitching that we call shivering. It burns fuel rapidly and generates quite a bit of heat. Unfortunately, it often doesn't begin until the body core is already under some stress; so if you begin shivering, it's a good idea to get out of the cold right away if you can.
hey! hey apple hey!
The muscle contracts repeatly because fast musclar movements keep your body warm
We do this to preserve body heat as we move blood pumps through our body and keeps our internal body temperature normal. It's just a natural reaction to the cold.
You shiver when you could because that is a way that your body naturally does to try to stay warm. So if you start getting cold you should get some where, were it is warm.
There are various reasons that you could feel cold and shivery. If you feel this way even when it is warm, consult a doctor.
it is an reaction from the body telling that u are cold and it is trying to warm its self up.
yes
you shiver and become cold dee dee dee
how to calligram the word shiver in a poem
That is an excellent question although it is easy to answer. The answer sadly is no because you need to look at what shivering is. When you shiver you are increasing muscle movement which stimulates blood flow to the area. This increased blood flow results in more heat since we are warmblooded and heat is produced in our core. Cold-blooded animals on the other hand would gain nothing from shivering except to waste energy pumping extra blood to an unneeded area. According to Wikipedia, pythons sometimes shiver, even though they are cold-blooded animals.
They are probably referring to Quaking Aspens.
