It is possible to improve mental endurance in much the same way it is possible to improve physical endurance: through practice and mental exercises. It is necessary to constantly stretch and challenge the brain in order to build endurance, and to prevent problems such as memory loss or lapses in concentration. One of the best ways to improve mental endurance is to challenge the brain through puzzles such as crossword puzzles. Physical exercise actually improves brain function as well, because it encourages more blood flow to the brain.
Crossword puzzles force you to think differently than you normally do, and to recall facts and vocabulary that you may have temporarily forgotten. There are a number of games that can be found online or as a video game that promise to challenge the brain and boost mental endurance as well. These are often memory games or math games, such as Sudoku, that force you to concentrate and to identify patterns. Even though you may be having fun playing these games, they are improving your mental endurance at the same time.
Mental endurance can also be improved by consciously trying to concentrate more throughout the day. Rather than splitting your attention between work and email, for example, try turning off the email while you are working, and only focusing on one thing at a time. Initially, this may be difficult; you might only try to go an hour or two without checking email, but gradually trying to increase the time you spend in focused work can greatly improve your concentration. Conversely, taking a brief break a few times per day to walk around the office, or simply stretching at your desk, can give your mind a break and give you greater concentration when you return to work.
Challenging the brain to learn something new is another way to improve mental endurance. Learning to play a musical instrument or learning a second language are two of the most popular, but learning anything new can be beneficial to the brain throughout your life. Starting a new hobby such as crafts or photography can also help to boost mental endurance. The way you spend your down time has a big impact as well; given the choice, it is best to sit and read a book or to go for a walk outside than to simply zone out and watch television. Improving your concentration and mental focus should be a daily practice, and over time you will begin to notice a big difference in your ability to concentrate and remember things.
