Promotes brain growth:
Games like chess that challenge the brain actually stimulate the growth of dendrites, the bodies that send out signals from the brain’s neuron cells. With more dendrites, neural communication within the brain improves and becomes faster. Think of your brain like a computer processor. The tree-like branches of dendrites fire signals that communicate to other neurons, which makes that computer processor operate at a fast, optimal state. Interaction with people in challenging activities also fuels dendrite growth, and chess is a perfect example.
It exercises both sides of the brain:
A German study indicated that when chess players were asked to identify chess positions and geometric shapes, both the left and right hemispheres of the brain became highly active. Their reaction times to the simple shapes were the same, but the experts were using both sides of their brains to more quickly respond to the chess position questions.
Sparks your creativity:
Playing chess helps unleash your originality, since it activates the right side of the brain, the side responsible for creativity. One four-year study had students from grades 7 to 9 play chess, use computers, or do other activities once a week for 32 weeks to see which activity fostered the most growth in creative thinking. The chess group scored higher in all measures of creativity, with originality being their biggest area of gain.
Raises your IQ:
Do smart people play chess, or does chess make people smart? At least one scientific study has shown that playing the game can actually raise a person’s IQ. A study of 4,000 Venezuelan students produced significant rises in the IQ scores of both boys and girls after four months of chess instruction. So grab a chess board and improve your IQ!
