What could be the reason of sudden high vaginal temperature?

A sudden high vaginal temperature can indicate an infection, such as a urinary tract infection or sexually transmitted infection, which often raises body temperature. Hormonal fluctuations, particularly during ovulation or menstruation, can also cause temporary increases in vaginal temperature. Additionally, factors like physical activity, stress, or overheating can contribute to this change. If the elevated temperature persists or is accompanied by other symptoms, it's advisable to consult a healthcare professional.
