We can't all have an IQ of 155 or over, the level generally associated with genius.
However, we can all take steps to make the very best of the brain power we've been given. You can't transform your levels of intelligence but you can certainly improve, or at least sharpen it, as we shall now see...
Eat your way to intelligence
Health experts believe the human brain is constantly in need of the right nutrients and balanced foods to help it function effectively. There's a long list of foods that actively help the brain and an equally lengthy list of foods that adversely affect it. In summary, you should eat foods high in essential fatty acids (omega 3 and omega 6), remember to take plenty vitamins and minerals (particularly the B vitamins), and finally avoid foods high in trans or saturated fat.
Keep drinking that water
The human brain is 78% water so dehydration will significantly reduce its performance levels. You need to drink at least six glasses a day to allow you to think clearly. It will also help reduce headaches, tiredness, dizziness and depression.
Use both hands
Research has suggested that using your left hand more often (or your right if you're left handed), can help stimulate parts of the brain that you don't normally use.
Less stress, more relaxation
Stress has a cumulative effect on your brain, particularly on its ability to learn and remember. Sometimes we can’t avoid stress, but we can take steps to release or discharge its effects. Everything from doing yoga, to taking a walk, to soaking in the bath will help relax the body and the mind.
Don't forget to sleep
Over time, sleep deprivation will undoubtedly have an adverse affect on your brain and its capacity to function properly. You must get at least seven hours each night and try to ensure those hours are good ones. Take a look at the best tips for a deep, restful sleep.
