A person's core body temperature rises during exercise. Sweating increases, and their temperature returns towards its normal range.
Which response would normally follow?
Sweat production increases further, so temperature continues to fall.
Sweat production decreases, so excessive further cooling is limited.
Shivering increases further, so temperature continues to rise.
Shivering decreases, so heat production increases further.
