why we feel cold in fever?

Answer:
Cold is something you feel through your skin.When you have fever, there will be a lot of heat generated in your body. If your inner body is hotter than that outside, then the outer boundary which is your outer body that is separating them will feel colder, hence you feel cold.By using comforters, blankets, you are ensuring that your outerbody also experience the same temperature as in side your body.

When your body reaches high temperatures, heat receptors send messages to your brain to cool down your body. From the brain, messages are sent to your epidermis to dilate the blood vessels so that heat will be lost. In the process, the surface epithelium is cooled down as sweat is evaporating from your body. This is called a negative feedback mechanism. It is done to maintain homeostasis of body temperature.

Your body feels cold when the outside temperature is lower than your body temperature. When you have fever, your body temperature is high and the outside temperature is lower than your body temperature. So you feel cold at normal room temperature.
