Low fever and fatigue

Body temperature is one of the most important life characteristics of human beings. It fluctuates within a certain range with the change of 24 hours, day and night, rather than constant. There are three methods to measure body temperature, including oral cavity temperature, axillary temperature, and anal temperature. Among them, axillary cavity and oral temperature are more commonly used. Normal human body temperature is usually 36.6 ℃ -37.4 ℃. If someone's armpit temperature fluctuates between 37.4 ℃ -38.3 ℃, it can be called low fever. And long-term low fever often indicates that a certain problem may occur in the body, which will cause the body to consume exhaustion, need attention, and need to see a doctor in time.
