In what way can exercise affect stress levels?

Exercise positively affects stress levels primarily by triggering the release of endorphins, which are neurotransmitters that promote feelings of happiness and euphoria. This process is known as the "runner's high." When individuals engage in physical activity, their bodies produce these natural mood lifters, which help alleviate feelings of stress and anxiety. Moreover, regular exercise can enhance overall mental well-being, reduce the perception of stress, and improve coping mechanisms when confronted with stressors.

Additionally, exercise can improve sleep quality and boost self-esteem, further contributing to a more positive mood and reduced stress levels. Unlike the other options, which suggest negative effects or no impact, the evidence supporting the beneficial role of exercise in stress reduction is well-documented in scientific literature. This highlights the importance of incorporating physical activity into stress management strategies.
