why can a fever be a good thing for the body?

Answer 1

there are some theories stipulating that when you get an infection, the fever is actually doing something helpful to fight off the infection. perhaps the antibodies work better at a higher temperature somehow, or maybe it's just a simple matter of increasing the blood flow. there are other theories that the fever itself does not serve any useful function and it's just a byproduct of your body's efforts to fight the disease.

whatever the case, if the temperature is too high, that can be dangerous- you may suffer a febrile seizure.

Answer 2

Babies, and actually all children up to the age of 2 years old, do not have fully developed immune systems yet. When children are breast fed, the mother passes along her antibodies to the child. Thus, the baby is aquiring antibodies from the mother for quite some time. So, a fever would be beneficial for babies at this young age because it would prevent them from getting sick while having an underdeveloped immune system.

This is the reason that it seems like little kids are constantly sick...they are! The fever is most likely at the newborn age when it would be extremely dangerous for the baby to get sick, as it may be not yet be strong enough to fight it. The immune system strength constantly increases at this young age, so a 1 year old has a stronger immune system than a newborn and, therefore, does not perpetuate a constant fever, however, it is not until the age of 2 where the immune system is considered to be fully developed. Interestingly, the ages about 20-26 is when the immune system is the strongest it will ever be during life.

Fever can be good because it increases the pulse rate (which is same as heart beat rate), thus quickening the circulation and thus clearing some poisons out of the body. When sweating takes place, that also eliminates toxins. Fasting (generally done when we have a fever) is also helpful.

But uncontrolled fever can be dangerous to the body.

Answer 4

There are many causes,,,fever makes lymph nodes and in less degree, in the bone marrow, the release of the lymphocytes of white cells possible, also increases the effectivity of some proteins that protect us (like interleukynes) that work better at 38 centigrades or slightly above, it makes our body release some proteins from cells called phagocytes, that triggers the defense rteponse in others (called reticulo endotelial) around the vessels....
Fever can be good for the body, as long as it does not crosses certain lmits, after whatits dangerous (brain damage etc),,,,,However, fever is a defensive mechanism....

Answer 5

Temperature increases as internal process increases. Energies are being transfered into and out of our system, and therefore our bodies are thermodynamically working back towards equilibrium.

A fever mostly means our internal systems are fighting infection and trying to return everything back to the "normal" state.

Answer 6

As long as it is not too serious or harmful to your body from a previous condition, fevers sometimes help to flush out your system.

Answer 7

I'm not exactly sure, but they say that if you have a temperature it's a good thing because it means that your system is fighting off whatever is in your system that is bad. Your temperature goes up while it's fighting and goes away when it's done.

Answer 8

means that your body is fighting infection

Answer 9

yes it helps you get better faster
