Your brain needs exercise just like a muscle. If you use it often and in the right ways, you will become a more skilled thinker and increase your ability to focus. But if you never use your brain, or abuse it with harmful chemicals, your ability to think and learn will deteriorate.

Here are 5 simple ways anyone can squeeze a bit more productivity out of the old gray matter:

1. Play adventure video games.

Games can be a great way to stimulate the brain. Try to play a game that is out of your usual range of choices. It will help you think differently. Especially look for games that provide you with problems to solve or force you to think quickly. Scientific studies have shown that playing the popular game Tetris leads to more efficient brain activity; as players become more proficient at the game, their brains show a reduced consumption of glucose (the body’s main fuel). The conclusions of this study point out that glucose consumption is reduced when learning has taken place. This would be expected as when a person becomes more proficient in any activity, the effort required decreases. When playing first person shooter games, try to get into the atmosphere, look at details, think every move as if it were real. This way you don’t mindlessly finish the game, and you stimulate the brain to think more than just using reflexive actions.

2. Exercise, eat some brain food and avoid smoking.

I used to think that I’d learn more by not exercising and using the time to read a book instead. But I realized that time spent exercising always leads to greater learning because it improves productivity during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you feel invigorated and can concentrate more easily. Eating well is good for your mental as well as your physical health. The brain requires nutrients just like your heart, lungs or muscles do. But which foods are particularly important to keep our grey matter happy?

  • – Wholegrains: Like everything else in your body, the brain cannot work without energy. The ability to concentrate and focus comes from the adequate, steady supply of energy – in the form of glucose in our blood to the brain. Achieve this by choosing wholegrains with a low-GI, which release glucose slowly into the bloodstream, keeping you mentally alert throughout the day. Opt for ‘brown’ cereals, granary bread and brown pasta.
  • – Oily fish: Essential fatty acids (EFAs) cannot be made by the body and must be obtained through diet. The most effective omega-3 fats occur naturally in oily fish as EPA and DHA. Good sources include linseed (flaxseed) oil, soya bean oil, pumpkin seeds, walnut oil and soya beans. They are good for healthy brain function, the heart, joints and general well being. Oily fish contains EPA and DHA in a ready-made form, which enables the body to use it easily. The main sources of oily fish include salmon, trout, mackerel, herring, sardines, pilchards and kippers. Low DHA levels have been linked to a higher risk of developing Alzheimer’s disease and memory loss.
  • – Berries: Evidence accumulated at Tufts University in the United States suggests that the consumption of blueberries may be effective in improving or delaying short term memory loss. Widely available, so there’s no excuse. Blackcurrants has one of the best source of Vitamin C, which has long been thought to have the power to increase mental agility.
  • – Broccoli: A great source of vitamin K, which is known to enhance cognitive function and improve brainpower.
  • – Nuts: A study published in the American Journal of Epidemiology suggests that a good intake of vitamin E might help to prevent cognitive decline, particularly in the elderly. Nuts are a great source of vitamin E along with leafy green vegetables, asparagus, olives, seeds, eggs, brown rice and wholegrains.
  • – Add vitamins: Certain B vitamins – B6, B12 and folic acid – are known to reduce levels of homocysteine in the blood. Elevated levels of homocysteine are associated with increased risk of stroke, cognitive impairment and Alzheimer’s disease. A study of a group of elderly patients with mild cognitive impairment found that after two years of intervention with high doses of B6, B12 and folic acid there was significantly less brain shrinkage compared to a subset given placebo treatment.
  • Avoid smoking! Smoking harms your brain as well as your body, it leads to sharp decline in mental ability. It causes stroke – damage to the brain due to problems with blood flow or the escape of blood into brain tissue. It is known to be highly damaging to physical health, being a major factor in cancer and heart disease. Now, however, its alarming effects on the mental well-being of millions of smokers have been outlined by British scientists. Lighting up regularly has been associated with a sharp decline in the performance of the brain, according to their study. They found that middle-aged smokers performed less well on tests compared with those without the tobacco habit. They also found that high blood pressure and being overweight took their toll of brainpower – but not as much as smoking.


3. Read Challenging Books.

Many people like to read popular suspense fiction, but generally these books aren’t mentally stimulating. If you want to improve your thinking and writing ability you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more precise, elegant English. Don’t be afraid to look up a word if you don’t know it, and don’t be afraid of dense passages. Take your time, re-read when necessary, and you’ll soon grow accustomed to the author’s style. Once you get used to reading challenging books, I think you’ll find that you aren’t tempted to go back to page-turners. The challenge of learning new ideas is far more exciting than any tacky suspense-thriller.

4. Early to Bed, Early to Rise.

Nothing makes it harder to concentrate than sleep deprivation. You’ll be most rejuvenated if you go to bed early and don’t sleep more than 8 hours. If you stay up late and compensate by sleeping late, you’ll wake up lethargic and have trouble focusing. In my experience the early morning hours are the most tranquil and productive. Waking up early gives you more productive hours and maximizes your mental acuity all day. If you have the opportunity, take 10-20 minute naps when you are hit with a wave of drowsiness. Anything longer will make you lethargic, but a short nap will refresh you.

5. Take Time to Reflect.

Often our lives get so hectic that we become overwhelmed without even realizing it. It becomes difficult to concentrate because nagging thoughts keep interrupting. Spending some time alone in reflection gives you a chance organize your thoughts and prioritize your responsibilities. Afterwards, you’ll have a better understanding of what’s important and what isn’t. The unimportant stuff won’t bother you anymore and your mind will feel less encumbered. I’m not saying you need to sit on the floor cross-legged and chant ‘ommm’. Anything that allows a bit of prolonged solitude will do. One of my personal favorites is taking a solitary walk. Someone famous said, “All the best ideas occur while walking.” I think he was on to something. Experiment to find the activity that works best for you.

Conclusion – I hope you aren’t disappointed that none of the techniques I’ve proposed are revolutionary. But simple, unexciting answers are often the most valid. The challenge is having the will to adhere to them. If you succeed in following these 5 tips, you’ll be rewarded with increased mental acuity and retention of knowledge.
