# Don’t Sleep On This: What a Low-Grade Fever Could Be Trying to Tell You When you’re under the weather with a low-grade fever, it’s easy to shrug it off—after all, it’s just a slight rise in temperature, right? But beneath that seemingly minor symptom may lie a crucial message from your body. Don’t sleep on this: your low-grade fever could be trying to tell you something serious. Understanding its signals can help you respond early and protect your health. ## Why Does a Low-Grade Fever Happen? A low-grade fever typically ranges between 98.6°F (37°C) and 100.3°F (38°C)—slightly above normal but often not alarming at first glance. It commonly occurs as your immune system fights off infections like colds, mild flu, or early viral illnesses. Unlike high fevers, which usually indicate stronger inflammation, low-grade fevers often develop gradually and persist for days.
