The most common reason for going to the doctor is an elevated body temperature. By itself, this condition does not pose a threat, but almost always is an indicator of malfunctions in the body.
A temperature above 38 degrees is typical for colds 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 of "necessary defense".
As you know, at high temperatures, our immune system begins to intensively produce white blood cells that fight viruses. In addition, high temperature in itself prevents the growth of pathogenic microorganisms. But, as practice shows, temperature increase is not always associated with infection or inflammation. There are many reasons why a fever can begin. Let's consider some of them.
Body overheating
At the beginning of the summer season, one cannot help but recall such a problem as sunburn. Against their background, a high fever without symptoms of the disease may well occur. In this case, an antipyretic can be used, since an increase in temperature is not connected in any way with the reaction of the immune system. An aspirin tablet will alleviate the condition and reduce pain. In addition, you can use an anti-burn spray with an anesthetic effect.
Infants in sultry summer days suffer no less. Parents, fearing drafts, too confuse the baby, not taking into account the fact that, unlike an adult, he will not be able to get rid of excess clothing if necessary. Remember that in infants in the first months of life, the body's thermoregulation system is very imperfect, so they suffer even more heat than hypothermia. In this case, a high temperature without symptoms of any disease can occur precisely as a result of overheating.
Vaccination
Often, parents have to face the fact that the baby's temperature jumps after a planned vaccination. I must say that in this case, a high temperature without symptoms of a cold is a completely normal and permissible phenomenon. For example, a measles vaccine often causes a slight rise in temperature 3 to 5 days after vaccination. In fact, a similar 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 vaccine from the pediatrician. If after vaccination a high temperature rises without symptoms of inflammation or a cold, and the child as a whole feels normal, it is better not to use antipyretic drugs at least during the day. Of course, we are talking about a temperature of no higher than thirty-nine degrees.
Vegetative-vascular dystonia
VVD is a fairly common disease that occurs in both adults and children. The main reason for this ailment, experts consider stressful conditions, high nervous loads, adverse environmental conditions. In adolescence, the symptoms of VVD can occur against the background of a hormonal surge and lag in the development of the cardiovascular system from the total muscle mass of the body. Temperature jumps are typical for patients with a diagnosis of VSD of asthenic type. In this case, the temperature can rise to 38 - 39 C, although this is not typical for the general clinical picture of the VSD.
Growth problems
An elevated temperature in a teenager without symptoms of any disease may be due to an increase in the thymus gland. In girls, an increase in temperature is often accompanied by an ovulation process. According to experts, children and adolescents are more sensitive to stress, and their temperature above normal may well rise against the background of unrest and anxiety. For example, on the eve of an important exam.
Body temperature - an individual value and a generally accepted value is not an unconditional norm for everyone. This is just an average value that can fluctuate. Body temperature at rest is usually lower than after active movement. Toward evening, the readings of the thermometer 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, a significant increase in the thermometer can be observed. Therefore, keep in mind that the numbers themselves are not a reason to panic. If elevated body temperature is not accompanied by other symptoms of the disease, perhaps this indicator is the norm for you.
