Fevers
What Is a Fever? A fever is when your body temperature rises above the normal range (about 98.6°F / 37°C ). Usually: 100.4°F (38°C) or higher = fever 99–100°F (37.2–37.8°C) = low-grade fever Instead of being “just sick,” fever is actually your body’s defense system in action . 🦠Why Do We Get Fevers? When germs (like viruses or bacteria) invade your body, your immune system sends out little messengers called pyrogens . These pyrogens run to your brain’s “thermostat” (the hypothalamus ) and raise your body's temperature. Why? Because higher temperatures make it harder for germs to grow and help your immune cells work faster. Basically: a fever is your body’s way of fighting back. ⚠️ Common Causes of Fever Infections (colds, flu, ear infections, strep throat) 🤒 Inflammation (autoimmune diseases, etc.) Heat exhaustion or sunburn ☀️ Side effects from medicines or vaccines 💉 Very rarely, more serious illnesses 🩺 What Does a Fever Feel Like?
