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 malfunctioning in the body.

The temperature above 38 degrees is typical for cold and viral diseases, such as acute respiratory infections, influenza, tonsillitis, 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 our immune system begins to produce vigorously 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 recalling such 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 suffer no less. 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 infants 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 on days 3-5 after vaccination. In fact, this reaction of the body is caused by the penetration of foreign bodies, in this case gamma globulin.

Of course, parents should learn more about the effects of each individual vaccination from a pediatrician. If, after 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 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 that occurs in both adults and children. Experts consider stress to be the main cause of this ailment, high nervous loads, adverse environmental conditions. In adolescence, the symptoms of VSD can manifest themselves 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 diagnosed with asthma. 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 symptoms of any 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 background of worries and emotions. For example, on the eve of an important exam.

Body temperature - the value of an individual and common value is not an unconditional norm for all. It's just an average value that can fluctuate. Body temperature at rest is generally 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 the natural physiological processes in girls and women. Even against the background of strong excitement, there can be a significant increase in the thermometer. Therefore, please 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.
