Aerobic exercise such as dancing, swimming, jogging, or going for a long walk, will increase blood circulation to the brain – particularly to the limbic system, which controls motivation and mood; the amygdala, which generates fear in response to stress; and the hippocampus, which is important to memory formation as well as mood. If you’ve ever gone for a run or exercised after a stressful day, chances are you felt a little better afterwards.

Because these systems respond to emotions like love, the greater the endorphin surge in these brain areas, the more euphoric the runners reported feeling. Though you’ll
