You might feel like you are going to die or at least incredibly uncomfortable but this feeling can be a good thing. Fevers are commonly looked at as a negative sign but they are actually a sign that the body is stimulating the immune system and accelerating detoxification!

A fever is the body's natural defense system against an invading microbe. First, the white blood cells wage the battle and release  chemicals called pyrogens.  Secondly, these pyrogens activate the hypothalamus (part of the brain that regulates temperature) to increase body heat to fight off the invaders.  This is when you might feel really cold and even begin to shiver as your temperature increases but this is actually a good thing because your body's immune system is working hard to  fight off those microbes.  Embracing a fever instead of suppressing it could aid in a faster recovery from the flu.
