Moving Your Mind for Maximum Fitness

  When people design a new workout programme, they often target their chest, stomach, and leg muscles, hoping to sculpt the perfect physique. However, they often neglect the most important part of the body: the brain. Our brains grow stronger when we exercise them and weaker when neglected. To assist in keeping our minds sharp, several websites and apps offer brain games to help us get our mental workouts accomplished in a very short time.

  As we age, our vocabulary continues to expand and we become better at creative plans. However, by the time we enter our 20s, our prefrontal cortex starts to shrink. Although part of the reason for our decline is physical, there is evidence that targeted exercises can halt or even reserve cognitive damage. Throughout our lives we maintain the ability to create new neurons whenever we learn something new, like a foreign language or a new sport. By repeating these activities we create new pathways and connections between neurons that keep our minds functioning at an optimal level. This is what brain fitness exercises aim to accomplish.

  These digital exercises are broken into different categories. The first is memory exercises. These programmes display information to users and then quiz us to see how much we can recall. The second type is attention exercises. These games get users to focus on multiple tasks at once, dividing their attention. Although trying to concentrate on several things at once during work is not recommended, doing it in a game environment can help to strengthen our focus in the long term. Speed exercises, on the other hand, are designed to keep our minds agile. In addition to these major categories, there are other games that focus on specific situations like remembering names and faces, or calculating directions.

  Although many users rave about positive effects of these games, there are other hacks we can use to strengthen our brains. One is napping. Studies have shown that people who nap in the afternoon fared much better at mental tasks than those who didn’t. A little caffeine can also make your mind sharper, as long as you don’t overdo it. Finally, getting some physical exercise also tends to improve the clarity of our thinking. In other words, maybe the Roman poet Juvenal was on to something when he wrote “A sound mind in a healthy body”.
