when you have a fever are you hot or cold

You can actually feel both hot and cold with a fever: your body temperature is high, but you may feel cold (chills) at some points and hot at others.

What’s really happening

• A fever means your internal body temperature is higher than normal, usually 38 °C (100.4 °F) or more.

• On the outside, your skin often feels warm or hot to other people, and you may sweat.

• At the same time, you can feel cold, get goosebumps, and shiver because of how your brain is resetting your “thermostat.”

Why you feel cold with a fever

• Your brain (specifically the hypothalamus) raises your set‑point temperature to help fight infection.

• Until your actual body temperature catches up to that new higher set‑point, your brain treats you as “too cold,” so you feel chilly, get shivers, and want blankets.

Why you feel hot later

• Once your temperature reaches or exceeds that higher set‑point, or when the fever starts to come down (naturally or with medicine), your brain now thinks you’re “too hot.”

• That’s when you feel flushed, sweaty, and uncomfortably warm, even if the room isn’t very hot.

Simple way to think about it

• Early fever or while it’s climbing:
  • You feel cold (chills, shivering) but are actually running a temperature.
• When the fever peaks or breaks:
  • You feel hot (flushed, sweaty) and may want fewer layers.

When to be concerned

• Get medical help urgently if there is:
  • Fever above about 40 °C (104 °F), confusion, trouble breathing, chest pain, stiff neck, seizures, or a rash that doesn’t fade when pressed.

• For milder fevers, rest, fluids, and light clothing/blankets usually help; use fever‑reducing medicine only as directed by a healthcare professional.
