What are the possible causes of a persistent body temperature of 37°C?

A persistent body temperature of 37°C may be caused by multiple factors: 1. Normal physiological phenomenon: The normal axillary temperature for humans generally ranges between 36–37°C. A constant temperature of 37°C may fall within the normal range, especially considering individual differences. Body temperature may also fluctuate due to environmental factors, physical activity, diet, and other influences. 2. Environmental factors: If the ambient temperature is too high or clothing is excessively warm, it may impair the body's heat dissipation mechanisms, leading to an increase in body temperature. 3. Physiological changes: Events such as ovulation, menstruation, and pregnancy in women, which involve changes in hormone levels, may cause an elevation in body temperature. 4. Medical conditions: Conditions such as upper respiratory tract infection, hyperthyroidism, and pulmonary tuberculosis may also result in a sustained body temperature around 37°C. If any discomfort symptoms occur, it is recommended to seek immediate medical consultation and treatment.
