Though it has been mentioned earlier about how reading can improve concentration and critical thinking, there is another part of mental health that reading helps to improve. This point is stated by NCU on their blog. Reading at least a little each day can improve your focus and your memory function. In this instance as well, reading stimulates the brain, particularly the part of the brain that helps with memory and attention. Just like with physical exercise, reading is a form of mental exercise that pushes your memory and focus to the limits.
Simple reading comprehension improves your memory function. Remember the tests in elementary school where you were tested to see how much you retained while reading those short stories. Well, the reading comprehension as an adult works the same way. While reading, your brain is constantly retaining pieces of information about the story. Because the part of the brain that controls memory is stimulated, it acts like exercise for this part of the brain, resulting in improved memory.
How does your focus improve through reading? Your focus is strengthened through reading because it requires focus to read. When sitting down to read a book or article, you will not understand what you are reading unless you’re focused. Consider what it is like when doing a math problem. To get it correct, you have to focus intently on that problem. The same goes for reading. Again, like the memory function in your brain, your focus is exercised, which helps to improve your overall focus.
