What is the biological benefit to it?
In: Biology
The reason is that you are radiating a bunch of heat. You feel that flow of heat as being cold. The benefit is under normal conditions this leads to you to get warm again and stops you from freezing. When you have a fever the benefit is that you still will seek to get under blankets and that makes it so you can maintain the fever for less energy cost. This makes you more likely to survive. Understand fevers are your bodies last Hail Mary attempt to not die from infection. If you have a fever you are in a bad way. If you can use less energy for the same effect here than that is a huge deal.
