Answer to Question 2

By engaging in physical activity, you are able to reduce muscular tension and eliminate the physiological changes that triggered the fight-or-flight mechanism. Further, during vigorous aerobic exercise lasting 30 minutes or longer, morphine-like substances referred to as endorphins are thought to be released from the pituitary gland in the brain. These substances not only act as painkillers but also seem to induce the soothing, calming effect often associated with aerobic exercise. Research has also shown that moderate-intensity exercise has an immediate effect on a person's mood and the effects last up to 12 hours following activity. Thus exercise mitigates the daily stress that leads to mood alterations. Exercise is free and easily accessible to everyone. Pick an activity that you enjoy and use it to combat stress, blue moods, anxiety, and depression.
