Why is it when you have a fever feel so cold?

When you have a fever, your body temperature is elevated. This can cause you to feel cold for several reasons.

Increased heat loss: Fever causes your blood vessels to dilate, which allows more blood to flow near the surface of your skin. This can cause you to lose heat more quickly, which can make you feel cold.

Shivering: Your body also produces more heat when you've got a fever, and this can cause shivering, which can make you feel even colder.

Dehydration: Fever can cause you to become dehydrated, which can also cause you to feel cold.

In addition these factors, fever can also cause your body to feel achy, which can make it even more difficult to feel comfortable.
