George's skin became very hot, and all of a sudden, sweat soaked his clothes.
Ahh, I feel so cool now.
George felt a sudden period of cooling as he tried to shake the sweat off his shirt.
I feel so happy now that my sweat has cooled me down.
What George is experiencing seems to be a negative feedback loop
No George, it is actually the opposite. George's automatic nervous system (ANS) and central nervous system (CNS) are utilizing sweat glands (effectors) to release sweat to lower the body temperature.
The nervous system helped George regulate his body temperature when playing basketball, making him a happy guy.
