Have you ever queried why does your body temperature rises during fever? Although this is a resistance mechanism of the body, it produces offensive symptoms.

Fever or pyrexia is a medical symptom that happens when the body temperature is higher than normal conditions. This is a protection mechanism, and the most maximum of the population has gone within it at some point in their life.

The causes why we have a fever are various. Many times, it is linked with the appearance of pathogenic organisms in the body, which are recognized as foreign substances.

This drives us to question why body temperature rises during occurrences of fever. In the first situation, it may appear counterproductive. Since all the symptoms linked with an unusual increase in body temperature are attached to the discomfort caused by the germ in question.

However, like all human physiological responses, fever has evolutionary importance. In this article of Health Fuller, We tell you why does body temperature rise during fever. Stay Tuned!

What is considered a fever?

As a general rule, any body temperature above 37 ° C represents a fever occurrence. Still, four types of medical symptom can occur:

  • Low-grade fever: Meanwhile the body temperature does not surpass 38 ° C. This is what we all recognize as having a few tenths.
  • Moderate fever: The temperature varies between 38 and 39 ° C.
  • High fever: Higher than 39 ° C.
  • Hyperpyrexia: When the temperature is equivalent to or higher than 40 ° C.

When a sufferer enters hyperpyrexia, complications emerge fast. A range of denaturations of nervous order proteins can happen, with various associated failures and a high possibility of death if quick medical care not implemented.

Why does fever happen?

This response of the body to outer agents can shift against us if we do not control it. So, the question about the value of it is worth it again. Why does the body produce temperature if it can be dangerous?

First, of all, we have to understand fever as an ancient defense mechanism. The hypothalamus, the part of the brain responsible for controlling body temperature, conveys signals to increase it when it recognizes molecules named pyrogens in the blood.

A pyrogen is any fever-producing substance. These are normally polysaccharides, for example, debris or products of the cell wall of bacteria, too.

The immune system, which creates inflammation, acknowledges as protection against the presence of invaders in the human body. In this way, fever is one more factor to defend yourself.

The internal body system hopes that, by raising the temperature, the microorganisms that are most delicate to changes will fall when presented to higher values. Most infection-causing bacteria and germs thrive at 37.5ºC

As the temperature rises, microorganisms stop following. Or at least, they don’t do it so swiftly and efficiently. Therefore, their vulnerability to the agents of the immune system boosts. Fever is, therefore, an evolutionary mechanism with a definite purpose: to minimize pathogenic microorganisms.

Fever supports fight disease, but it can also lead to destruction or cause an irreversible loss in severe clinical circumstances. Should Doctors Allow Increase In Body Temperature? Up to what limit?

This is a dispute in medicine. While some experts favor that the fever is retained at average levels so that the immune system reacts better, others are in support of trying to reduce it with antipyretics. There is no single answer to this point. Yes, they all accept that above 39 ºC the sufferer must be treated.

For this purpose, there are over-the-counter medicines, such as paracetamol or aspirin, to lower body temperature. As modern medication has provided us antivirals and antibiotics. It is not so important that we encounter a drastic temperature rise to fight the fever.

Fever is a reason for consultation

Fever is one more extra protecting mechanism that the human body produces in motion to dismiss potential pathogens. This not only can annihilate itself with some microorganisms that are very sensitive to temperature fluctuations, but it also reduces the most defiant ones.

For parents, particularly, the appearance of an increase in body temperature in children results in a bothersome situation. We have to differentiate among the initial low-grade fever, which may not surpass 38 ºC, from that fever that rises too high.

In one way or another, fever is a reason for discussion. If you notice an increase in body temperature, it is sufficient to visit the medical team to find the reason and treat it precisely.
