The internal temperature of our organism, under generally normal conditions, is about 37ºC. Above this figure, it can be considered that the normal body temperature has risen.
In this sense, the fever it is a natural response that our organism has to defend itself from external agents (bacteria, fungi, viruses ...), as well as external ones.
For this reason, it is useful and appropriate to know the different symptoms of fever . And it is that far from that high fever can be considered a problem, we must not forget that it is a natural response, which should not alarm, but we must monitor its evolution.
But, what causes fever ? What are the main causes of fever ?
Causes of fever
Our thermoregulatory center tends to be altered and to raise the temperature mainly due to the action of external agents, such as viruses, bacteria, fungi, or some drugs that can cause a rise in body temperature.
From an internal point of view, the main internal causes that can cause this rise in temperature through immune reactions, tumor polypeptides, internal substances such as hormones (especially progesterone), or protein fragments derived from inflammations or dead cells.
All these causes of fever Main causes that the defensive system of the human body releases some indigogenic pyrogens called cytokines, and that are those that provoke that elevation of temperature before external or internal aggressions.
