Fever and chills are common symptoms often experienced together, indicating the body’s response to infection, inflammation, or other underlying health issues. Fever is characterized by an elevated body temperature above the normal range, typically accompanied by feelings of warmth, sweating, and general malaise. Chills, on the other hand, are sensations of coldness or shivering, often occurring as the body attempts to raise its temperature to match the set point of the fever. These symptoms can be caused by various factors, including viral or bacterial infections, inflammatory conditions, autoimmune disorders, medication reactions, or exposure to environmental toxins. While fever and chills are often part of the body’s natural defense mechanism against infection, persistent or high fever, severe chills, or other concerning symptoms may indicate a more serious underlying condition requiring medical evaluation and treatment. Management of fever and chills typically involves rest, hydration, temperature monitoring, over-the-counter fever-reducing medications such as acetaminophen or ibuprofen, and addressing the underlying cause of the symptoms through appropriate medical interventions.
