Fever isn’t just a symptom - it’s a finely tuned biological mechanism that helps your immune system respond faster and more efficiently. Watch this reel to see immune cells moving faster when the temperature rises. Small increases in body temperature (just 1–2°C) have profound effects on immune cells, including dendritic cells, T cells, macrophages, and neutrophils, by directly influencing their motility, polarization, chemotaxis, and target-search behavior - all independently of the surrounding
