It is often said that “the only way to train the brain is exercise”, but there are many research results that exercise actually improves brain function.
However, I don't know how much exercise I should do and for how long.
Therefore, I would like to introduce a paper that “Exercise enhances emotional and cognitive functions”.
According to this paper, it is said that the performance of short-term memory will be improved and the mood will be improved even if the exercise of the intensity of riding a bicycle is performed for 15 minutes. If only 15 minutes is enough, it's easy to get around.
