7) Chills
As we have mentioned, fever is the result of an infection in the gallbladder, which releases a series of inflammatory signals to the brain. The brain centers start to increase the temperature threshold to fight off the pathogen microorganisms with a higher temperature. By increasing the temperature threshold, the rest of the body acts as if we were in a lower temperature and start doing something to create more heat.
The pulse, the blood vessels, the skin, and even the muscles respond to this increased temperature threshold, and that’s why we start feeling chills. By contracting repeatedly, the muscles are attempting to create more heat from energy, and you get goosebumps because the skin is trying to increase its surface to catch up as more heat as possible.
