Fever Fights Viruses by Protecting Cells, New Study Suggests

Scientists have discovered a key reason why fever helps our bodies combat infections. New research indicates that higher body temperatures actively protect cells from viral takeover. A study conducted on mice found that feverish heat makes it more difficult for viruses to copy themselves. The heat appears to shield cells by preventing viruses from hijacking their internal machinery. This research provides a clearer explanation for a common defense mechanism. It suggests the elevated temperature of a fever itself creates a less hospitable environment for viruses, aiding the immune system's fight.
