How Exercise Benefits the Brain
An experiment in Ireland found that young men who bicycled for half an hour improved their ability to recall names and faces. Scientists are attributing this to the increased amount of the protein BDNF found in the blood of those who had exercised. This protein promotes the health of nerve cells and could be the reason why exercise benefits the brain’s ability to remember and recall. Similar conclusions have been drawn from studies on the memory of rodents after exercise and then one which measured the BDNF level of pilots. There is mounting evidence that exercise can turn back the years when it comes to improving memory.
