Temperature without cause

A fever in a child for no apparent reason is an excuse for many parents, especially since an accurate diagnosis can not be made immediately. To clarify the situation, let's try to answer the questions "who is to blame?" And "what to do?".

When, at the seemingly completely healthy, that is, non-coughing, nonchalant and not complaining about anything, the child suddenly raises the temperature, parents turn to the pediatrician. And the doctor, after examining the baby and examining the results of the tests, only shrugs his shoulders: there are no signs of infections, the patient is healthy. Parents calm down, but after a while the situation repeats. Walking along the vicious circle continues until doctors exclude all obvious and unobvious reasons and the child does not get to see a neurologist. "Thermoneurosis" - that's what parents can hear from this specialist. Although it sounds incomprehensible and a little frightening, you can cope with this misfortune.

Limits of allowable

Before complaining to the doctor about the child's fever, parents should understand the term "age-related temperature norm" and find out what circumstances can affect the temperature readings.

So, in the baby of the first year of life the thermoregulation processes are not yet adjusted, so for him all the values, up to 37.5 ° C, are considered normal. By the year the temperature norm is reduced to 37 ° С. The measurement location of this parameter also has value. The thermometer readings in the armpit will be different from those obtained in the mouth or in the rectum. In the first case, the thermometer will be normal to 37 ° C, in the second - up to 37.1-37.6 ° C, and the third - even up to 37.6-38 ° C. The most objective in young children are the readings when measuring the temperature in the ear canal. Here the norm varies between 36.9-37.4 ° C. The temperature also varies with the time of day. It is below all in the morning, and above - from 18 to 22 hours.

Increase body temperature, especially when measuring in the armpit, can eat food, physical and emotional stress, overheating.

What it is?

The thermoneurosis arises from the uncoordinated work of the thermoregulation center (it is located in the hypothalamus - the brain region) and the autonomic nervous system. Having received the appropriate signal, the center of thermoregulation with the help of the autonomic nervous system narrows or dilates the vessels, which leads to an increase or decrease in temperature, blood pressure and the rhythm of contractions of the heart. In adults, under stress, pressure usually jumps, children often experience a fever. Because sometimes, if the neuroendocrine system "remembers" such a mechanism of responding to a stressful situation and begins to replicate it, the child may develop a thermoneurosis. However, with the statement of this diagnosis, one must be extremely cautious, since periodic temperature rises are characteristic for other, and not necessarily infectious, diseases.

Usually, the disease manifests itself as a rise in temperature to subfebrile, that is, up to 37.5 ° C, values, but in some cases they may be higher. This event, as already mentioned, must necessarily be preceded by stress. For each child he is his own. For one kid they can become a kindergarten, for another - discord in the relationship between the parents, for the third - the misunderstanding of peers.

With thermoneurosis, the temperature does not decrease even after taking antipyretics. Check it out simply: measure the baby's temperature, and then give him an antipyretic. If in 20-30 minutes she did not start to decline, you can suspect that it's not an infection. If the child has no signs of infection or a viral disease: he does not lose weight, there is no cough, a cold, there are no wheezing in the lungs and bronchi, urine and blood tests are normal, the probability of thermoneurosis is not ruled out.

Doctors consider thermoneurosis one of the varieties of vegetative dystonia. In addition to high fever, the child can have fast fatigue, headaches, meteosensitivity and in some cases - instability of the stool.

Walking by the doctors

Naturally, if episodes of unreasonable rise in temperature are repeated time after time, or if fever lasts for at least a week, you must go to the pediatrician and take clinical tests of urine and blood. If they are normal, the pediatrician will refer the child to other specialists. This is a normal situation: in order to diagnose "thermoneurosis", doctors should exclude other, much more serious reasons for this state of affairs.

The rise in temperature can be the first sign of not only infectious and rheumatic and endocrine diseases, but also hereditary metabolic disorders. For this reason, the child must undergo a full-scale comprehensive examination of blood and urine for hidden infections, he will need consultations of an otolaryngologist, phthisiatrist, rheumatologist, endocrinologist, neurologist. We must exclude abnormalities in the pancreas and thyroid glands, serious problems from the nervous system.

A child with a thermoneurosis is seen with a neurologist. At the same time, the doctor regularly appoints him repeated blood and urine tests, tuberculin tests, ultrasound and x-ray studies, so as not to miss the "disguised" tuberculosis or some rare disease for thermoneurosis.


The treatment begins, strangely enough, with the fact that the child stops measuring the temperature. After all, the information that the thermometer "gives out" only supports stress, not only for the child, but also for his parents. The temperature is measured only if the troublemaker feels bad.

Within a few months, the baby is recommended to give sedatives (sedatives) in the age-appropriate dose. Only a neurologist can name specific medications and determine their exact dosage. It will also be necessary to adjust the load, adjust night sleep and daytime rest.

To achieve positive results with thermoneurosis it is possible, only strictly observing the regime of the day. In no case can not give up daytime sleep, you need to walk more often, more to move in the fresh air.

Note also that with such a diagnosis a child can attend a kindergarten only if he feels comfortable in a children's institution.

In addition, rehabilitation procedures are mandatory - physical therapy, reflexology, soothing baths. At home, it can be regular gymnastics and a non-extreme contrast shower. To understand with the emotional "trigger" of the rise in temperature will help a psychologist.
