why does the temperature of our body rises when we r down due to fever?

Answer 1

The cells of the immune system make and release substances especially the interferons which will cause muscles aches including fevers ( Pyrexias)


These substances activate the body's defenses against viral infection. For bacterial infections, cell wall proteins from the bacteria are often pyogenic (fever inducing).


And the fever is actually generated by the muscle "shakes" (rigors) during the shaking chills. Which is why temp goes up right after these.

If you get into a hot tub or shower when they come on, and
raise your temp that way, you won't be nearly so uncomfortable. The higher temps may help your immune response, also.

Most people do not understand the nature of a fever. A fever results when a foreign organism invades the body and the liver responds by releasing pyrogens which raises the body's temperature. It does this to fry out the enemy. So a fever is not a disease, it is an efficient immune response.

Letting this natural immune response to occur, actually, strengthens the immune system. It also lets the immune system develop a type of program (much like a computer program) on how to combat that particular virus/bacteria etc., if it were to be introduced into the body again

So remember... A Fever is not a Disease, it is the BODY SUCCESSFULLY COMBATING AN INVADING ORGANISM!!!

Answer 2

Thats how your body fights back, when you have a fever, the increase in temperature will start to slowly kill the virus or bacteria.

Answer 3

it is our body's way of saying its getting better, and our white blood cells are killing the infection or virus.
