Exposure to a hot environment causes the body to sweat. The hotter the environment, the greater the sweating. Two anatomy and physiology students are arguing about the mechanisms involved. Student A claims that they are positive feedback and student B claims they are negative feedback. Do you agree with student A or student B, and why? Through sweating, the body is able to cool off and regulate its normal temperature which is 370c. I agree with student B. When our skin is exposed to high temperatures, it reduces the set point of sweating and creates a negative feedback mechanism.
