Deep dives
The Historical Context of Exercise and Mental Health
The exploration of the relationship between exercise and mental health can be traced back to the 1970s when early psychiatric observations indicated that patients with depression benefited from exercise as much as from antidepressant medications. During that time, discussions emerged regarding exercise’s role in improving mood, sparked by events like the marathon craze in Boston. Observations revealed that individuals could self-treat attention disorders through regular exercise, with coordinated sports activities coinciding with improvements in behavior and academic performance. This growing recognition laid the groundwork for further studies linking exercise with various mental health outcomes.
