3 ways to boost your intelligence

1. Hit the gym
A study conducted at the Sahlgrenska Academy in Gothenburg, Sweden, has revealed that people who work out regularly have higher IQ scores. The study, which was published in the Proceedings of the National Academy of Sciences, involved more than 1.2 million Swedish men and the results show a clear link between physical fitness and IQ test scores.

2. Eat right
Research shows that a diet rich in omega-3 can increase learning ability. Why? There are cells in the brain that transmit messages to other parts of the body. The wall around these cells needs to be kept flexible in order for the cells to communicate properly. By boosting your omega-3 intake you restore elasticity, resulting in increased brain function. Conclusion? Eat at least one portion of oil-rich fish, such as mackerel, salmon or sardines, per week.

3. Train your brain
It’s long been suggested that number puzzles like Sudoku improve memory and that crosswords expand vocabulary, but according to a study at the University of Michigan in the US, brain games can also improve overall intelligence. The study, which involved 70 volunteers, saw 35 participants doing a series of mental exercises while the second group bypassed the ‘brain boot camp’. Those who worked on mental tests showed significant improvement in problem-solving ability.
