How exercise boosts brain health and memory: The science behind BDNF and Neuroprotection

We often hear that regular exercise keeps our bodies healthy. But what many people don’t know is that it also plays a major role in keeping our brains sharp. A short workout can do much more than burn calories. It can improve focus, memory, and even protect against brain diseases. Dr Kunal Sood shared on social media that just twenty minutes of moderate exercise after studying can help the brain remember more the next day. That simple act increases blood flow to the hippocampus, the area responsible for learning and memory, and raises the levels of a key protein that supports brain cells. A study published in Frontiers in Neurology supports this idea by explaining how physical activity boosts a protein called brain-derived neurotrophic factor, or BDNF. This protein helps br
