Night Sweats: Causes and Potential Health Conditions
Night sweats, also known as nocturnal hyperhidrosis, can be attributed to various factors including menopause, certain types of cancers, autoimmune diseases, infections, and even tuberculosis. Sweating is the body’s natural mechanism to regulate its core temperature when it exceeds the thermoneutral zone (TNZ). In the case of infections, the release of inflammatory factors in the bloodstream can temporarily elevate the TNZ, triggering the body’s response of chills and excessive sweating.
Fevers and Tuberculosis
Understanding the connection between fevers and tuberculosis is crucial in diagnosing and treating this infectious disease. In around 60-85% of active tuberculosis cases, individuals experience a low-grade fever. This fever tends to manifest in the late afternoon or evening and is more prevalent among patients under 60 years old. However, it is important to note that certain factors, including a history of TB, limited lesions, and specific strains of the bacteria, may be linked to the absence of fever in some cases.
