Why does exercise have such a big impact on the brain?

231 views

If I go 3 days without exercising, I start experiencing brain fog and get depressed & more anxious. When I workout again, I gain mental clarity, become more motivated to take on the day, and like 75% of the self-deprecating thoughts I experience go away. Why does this happen to me? What’s the science behind this?

Exercise (strength, endurance, etc) increases brain derived neuropathic factor (BDNF). This protein helps with brain cell survival (maintenance) and growth.

More exercise = more BDNF = more brain cell integrity
