Physical fitness begets neurofitness. It may be tempting to separate the two, but in truth, they are inexorably linked to your optimized thinking and functioning. We may not be able to specifically train the brain, but by training our bodies in specific ways, we can effect the changes that we want. The first step to physical fitness is to work up a sweat on a regular basis. Of note, this should be aerobic exercise that gets your blood pumping and your heart rate up. This also increases the blood flow to your brain, kicks off a host of metabolic and hormonal changes, and energizes you. It’s been shown that aerobic exercise can increase the size of parts of our brains responsible for higher cognitive functions and memory, and even fight cognitive decline and brain diseases. The brain is a hungry, hungry organ, so we should make sure the systems that feed it are optimized and healthy.
