Khaberni - Dr. Nadezhda Chernyshova, an internal medicine specialist and nutrition expert, indicates that a rise in temperature can be a result of stress and exhaustion.
According to the doctor, fever without a cough or a runny nose isn't always a sign of illness; it can sometimes be a natural response of the body to stress or fatigue. Fever typically accompanies infectious diseases, whether viral or bacterial, such as colds, sore throats, and respiratory or urinary infections, but it can occur sometimes without any clear symptoms, and this does not always indicate the presence of a disease.
The doctor explains: "Many microbes and viruses die at temperatures above 38 degrees Celsius, which stimulates the body's immune responses. Fever can thus be seen as a signal for the body to produce immune globulin proteins and activate cellular immunity, thereby serving as a natural mechanism that helps fight infections."
Chernyshova indicates that if fever is not accompanied by a cough, a runny nose, or other symptoms of illness, it could be due to stress, fatigue, lack of sleep, or psychological tension, pointing out that children in particular may experience fluctuations in body temperature due to their weak thermal system.
She adds: "If the temperature does not exceed 37.5 degrees Celsius and is caused by exhaustion or stress, then rest alone is sufficient for the body to recover automatically. However, if the temperature remains above 38 degrees Celsius for more than three days, or above 37.5 degrees Celsius for a week, this requires consulting a doctor to determine the real cause."
The doctor warns that prolonged or unexplained fever may be associated with chronic inflammatory processes, thyroid disorders, or even cancer, emphasizing the necessity to consult a specialist in such cases.
