Subfebrile

Low-grade fever is a slight delay or deviation in the body from the norm of temperature readings (36.4 °C), regarded by the patient as a manifestation of fever (fever). The symptom is constantly present or occurs periodically due to malfunctions of the nervous and endocrine systems. Depending on the cause, the manifestations have different symptoms: absence of elevated temperature due to external overheating of the body (during active and long stay in a hot room, in the sun); symptoms of a minor violation of thermoregulation: internal redistribution of heat (feeling of internal heat, rush of blood to the head).
