@curio3dd: Your body is already hot during a fever… so why do you suddenly feel cold and start shivering? 🥶🔥 Immune signals reach the hypothalamus, the part of your brain that controls body temperature, and temporarily raise your body’s temperature target. That’s why you shiver to create more heat — and why you may start sweating when the target returns to normal. When you have a fever, do you shiver more or sweat more?
