I think exercise can complement medication and therapy, but it’s rarely a full substitute. Physical activity boosts mood, reduces stress, and supports brain health by increasing endorphins and regulating neurotransmitters like serotonin and dopamine. It’s particularly helpful for depression, anxiety, ADHD, and mild cognitive issues. Science shows regular exercise improves sleep, cognitive function, and emotional resilience, making it a powerful tool alongside traditional treatments rather than a replacement.
