1. Introduction Chronic lack of sleep can cause a persistent low-grade fever by severely disrupting the central thermoregulatory centers in the brain. When the body is deprived of restorative rest, it induces a state of systemic inflammation and alters the natural circadian rhythms governing temperature control. This results in a mild, persistent elevation of core … Read more
1. Introduction A prolonged low grade fever often indicates a chronic occult infection, an autoimmune disorder, or an early neoplastic process altering the hypothalamic set point. When a fever persists for several weeks without obvious accompanying symptoms like a severe cough or acute gastrointestinal distress, it suggests the immune system is locked in a continuous, … Read more
1. Introduction to Low-Grade Pyrexia A low-grade pyrexia is a mild elevation in body temperature, typically ranging from 37.5 to 38.3 degrees Celsius (99.5 to 100.9 degrees Fahrenheit), indicating an underlying systemic inflammatory or infectious process. Normal human core body temperature fluctuates throughout the day, governed by circadian rhythms, hormonal cycles, and physical activity levels. … Read more

You should worry and arrange for a thorough medical evaluation if the fever persists continuously for … Read more
