Exercise works as an anti-depressant for some people. For example, studies have shown that high-intensity exercise releases feel-good chemicals called endorphins. Have you ever heard of the term “runner’s high”? That’s what joggers report feeling after prolonged exercise.
Although, The exercise doesn’t need to be high-intensity. Experts say, low-intensity training sustained over time can be just as valuable. This activity releases neurotrophic proteins or growth factors that cause nerve cells to grow and make new connections that improve brain functions and make you feel better.
In addition, neuroscientists have noticed that, with people who are depressed, the hippocampus in the brain is smaller – this is the region that regulates mood. Because exercise supports nerve cell growth in the hippocampus, this helps to relieve depression.
