Why does exercise improve mood?
Show answer & explanation
Answer: Brain releases feel-good chemicals
Sweat releases stored emotions — Wrong. Sweat is just water and salts—it doesn't contain emotions or mood molecules. The mood boost comes from brain chemistry changes triggered by exercise.
Brain releases feel-good chemicals ✓ — Correct! Exercise triggers release of endorphins, serotonin, and dopamine—your brain's natural mood elevators. Regular exercise can be as effective as medication for mild depression. Even a short walk helps!
Heart pumping removes stress toxins — Wrong. There's no such thing as 'stress toxins' that the heart pumps out. Mood improvement comes from brain chemicals released during exercise.
