If you want to power up your brain, have more conversations; the more conversations you have, the more intelligent you become. Simple brain games involving solving puzzles and naming objects can improve everyone’s IQ; start this kind of brain training as early as possible.
Increasing our vocabulary through communication is important for our intelligence levels, that is why kids whose parents read to them constantly have higher IQs, but the key is not just reading but to read interactively. This means you should show the relevant emotions as you read, using an interesting and varying tone of voice.
When you read to your child, look for signs of interest and ask questions as you go to make sure your kid understands what is being read, for example, you can ask “what do you think will happen next?”. This is where the real IQ boost comes from and what makes reading a fun social activity.
Probably, this is the most important and simplest thing you can do for your kid and it is why TV and audio stories will not do the trick. If you were never read to as a child, do not worry because exercising the brain is always a good idea, no matter what your age is.
Fun activities like Sudoku, crosswords or any similar activities that take your fancy can help improve your cognitive ability. One of the simplest things you can do to work your brain is to try to understand others’ points of view which you do not agree with; even struggling to understand a map will exercise your spatial and reasoning abilities.
Listen to arguments that make no sense to you and open your mind trying to find some sense in them. Finally, a great solution to a wide range of physical and intellectual problems is physical exercise, which is free and without any side effects.
