What happens to your brain when you exercise?

When you exercise, your brain gets a significant boost: blood flow increases, delivering more oxygen and nutrients, while chemicals like endorphins, dopamine, and serotonin are released, improving mood and reducing stress. Exercise also promotes neurogenesis (new brain cells), strengthens neural connections (neuroplasticity), and increases BDNF (brain-derived neurotrophic factor) to support learning, memory, and overall cognitive function, protecting against age-related decline and conditions like depression and dementia.

How does exercise affect your brain?

Exercise boosts brain health by increasing blood flow, delivering more oxygen and nutrients, and promoting the growth of new neurons and connections (synapses), especially in memory centers like the hippocampus, enhancing learning, memory, mood (via neurotransmitters like dopamine/serotonin), and overall cognitive function, while also reducing stress and disease risk. Aerobic activities like running or brisk walking offer significant benefits, improving brain structure and making it more resilient and adaptable.

What does 7 minutes mean in the human brain?

“ Some scientists claim that the brain might be active for a short time after someone dies, maybe 7 minutes or more.

So, by pulling together objects to appear more similar to each other, our brain tricks us into perceiving a stable environment.
