It is well known that body temperature is an important diagnostic indicator, and its elevated figures may indicate the occurrence of various pathological processes in the body. A significant increase in body temperature is almost always accompanied by other alarming symptoms and serves as a reason for contacting a doctor. But if it is higher than normal only half a degree, i.е. close to 37 ° C, and there are no other changes in the body, this can be confusing. With which there is a slight increase in temperature, and whether it is worth worrying about this, let us consider further.
Physiological causes of fever to 37 ° C
Not in all cases, a rise in temperature to such an index indicates a violation of health. After all, the temperature of 36.6 ° C is the standard accepted by most people, but not all. In individual cases, the individual temperature norm can fluctuate within 35.5-37.5 ° C, which is largely determined by the constitutional features of the person.
Also, the 37 mark on the thermometer may be the norm option:
- emotional shocks;
- at physical exertion;
- when in a hot place;
- after a dense meal;
- after staying in the open sun.
The reason for the prolonged temperature rise to 37 ° C in women, which also sometimes can fluctuate during the day, normalizing in the evening and in the morning, is often a change in the hormonal background associated with the menstrual cycle. Typically, this phenomenon is observed in the second half of the menstrual cycle, and with the onset of menstruation, the temperature returns to normal. In rare cases, women experience a slight increase in temperature in the first trimester of pregnancy.
Pathological causes of temperature 37 ° С
Unfortunately, often the causes of the temperature of 37 ° C, constantly elevated or rising by evening, are various disorders in the body of an infectious and non-infectious nature. We list some of the most common of these causes, as well as symptoms that can be noted:
