Why does the fever rise without symptoms?

The most frequent reason for going to the doctor is an elevated body temperature. In itself, such a condition is not a threat, but almost always an indicator of malfunction in the body.

Temperature above 38 degrees is typical forcatarrhal and viral diseases, such as acute respiratory disease, influenza, angina, bronchitis, tracheitis, pneumonia. In this case we are talking about the so-called pyrogenic reaction, as a result of which the human hypothalamus receives a signal about "necessary defense".

As is known, at a high temperature ourThe immune system begins to produce hard white blood cells that fight viruses. In addition, high temperature itself prevents the proliferation of pathogenic microorganisms. But, as practice shows, not always a rise in temperature is associated with infection or inflammation. There are many reasons why a fever can begin. Let's consider some of them.

Overheating of the body

At the beginning of the summer season, one can not help but recallsuch a problem as sunburn. Against their background, a high fever without symptoms of the disease may occur. In this case, you can use antipyretic, because the increase in temperature is not related to the reaction of the immune system. A tablet of aspirin will ease the condition and reduce pain. Additionally, you can use an anti-burn spray with anesthetic effect.

Breast children in summer hot days do not sufferless. Parents, fearing drafts, too wrap up the baby, not taking into account the fact that unlike an adult, he can not get rid of excess clothes if necessary. Remember that in babies in the first months of life the system of thermoregulation of the body is very imperfect, so they suffer a heat even heavier than hypothermia. In this case, a high temperature without symptoms of any disease can arise precisely as a result of overheating.

Vaccination

Often parents have to face the fact,that the baby is jumping after a routine vaccination. I must say that in this case, a high fever without symptoms of a cold is a normal and acceptable phenomenon. For example, vaccination against measles often causes a slight rise in temperature 3 to 5 days after vaccination. In fact, this reaction of the body is caused by the penetration of foreign bodies, in this case gamma globulin.

Of course, in more detail about the operation of eachParents should learn about a separate vaccination from a pediatrician. If after the vaccination a fever has risen without symptoms of inflammation or a cold, and the child as a whole feels fine, it is better not to use fever antipyretics for at least 24 hours. Of course, we are talking about a temperature of no higher than thirty-nine degrees.

Vegeto-vascular dystonia

VSD is a fairly common disease,occurring in both adults and children. Experts consider stress to be the main cause of this ailment, high nervous loads, an unfavorable state of the environment. In adolescence, the symptoms of VSD can manifest itself against the background of a hormonal outburst and a delay in the development of the cardiovascular system from the general muscle mass of the organism. The temperature jumps are typical for patients with an asthenic type of AVD. At the same time, the temperature can rise to 38 - 39 C, although this is not typical for the general clinical picture of the VSD.

Growth problems

Elevated temperature in adolescents without symptomsany disease may be due to an increase in the thymus gland. In girls, the temperature is often accompanied by the process of ovulation. According to experts, children and adolescents are more sensitive to stress, and the temperature above the norm may well rise against the backdrop of worries and worries. For example, on the eve of an important exam.

Body temperature is an individual andThe common meaning is not an unconditional norm for all. It's just an average value that can fluctuate. The body temperature at rest is usually lower than after active movement. Closer to the evening, the thermometer readings may change in the direction of increase. It happens that the temperature rises as a result of natural physiological processes in girls and women. Even against the background of strong excitement, there may be a significant increase in the thermometer. Therefore, note that the figures themselves are not a reason for panic. If the fever is not accompanied by other symptoms of the disease, it is possible that this is the norm for you.
