INSIGHT

Exercise Beats Medication For Many Cases Of Depression

Large meta-analysis (BMJ) of ~130,000 participants found physical activity 1.5× more effective than medication or psychotherapy for mild–moderate depression and anxiety.
Exercise changes hormones, neurotransmitters, and brain reward sensitivity, offering potent mental-health benefits.

Muscles Secrete Mood-Boosting Hormones

Muscles act as an endocrine organ, releasing myokines and anabolic hormones during contraction that influence mood and neurochemistry.
Exercise is a hormetic stressor that increases resiliency and sensitizes the brain to pleasure, breaking negative feedback loops.

Exercise Strengthens Immune Defense

Regular exercise enhances immunosurveillance, reduces systemic inflammation, and improves immunomodulation, lowering susceptibility to infections.
