Neuropsychologists now say that meditation can alter brain structure. MRI scans of long-term meditators have shown greater activity in the brain circuits involved in paying attention. When disturbing noises were played to a group of meditators undergoing an MRI scan, they had relatively little effect on the brain areas involved in emotion and decision-making as compared to non-meditators or less experienced
Although it takes time to learn to meditate well, this does seem to be effective in the long run to raise that IQ score of yours.
6. Take up creative tasks
Studying, performing, and producing art has been linked to strengthening certain parts of the brain associated with general intelligence. This link isn’t art-form specific, so feel free to do your thing, pick up that guitar write a verse or pick up a pen and paper once in a while and maintain a log diary or write an essay or just an email or at least text someone.
This not just improves your writing skills but also focuses on those new neural pathways which keep your brain efficient.
5. Get some good sleep
Everyone loves to push that snooze button on the alarm every morning and we can assure you that it isn’t all bad all the time. “If you are trying to learn something, whether it’s physical or mental, you learn it to a certain point with practice,” says Dr. Rapoport, who is an associate professor at NYU Langone Medical Center. “But something happens while you sleep that makes you learn it better. It’s called consolidation.” In short consolidation strengthens the skills that you learnt or practiced before you went to sleep.
Also in addition to consolidating memories, or making them stronger, your brain appears to reorganize and restructure them, which may result in more creativity as well. Researchers at Harvard University and Boston College found that people seem to strengthen the emotional components of a memory during sleep, which may help spur the creative process. So a good night of sleep is good for your brain, so hit that snooze once more.
Probably one of the most important steps to a better IQ and a better brain is regular exercise and physical fitness. We’ve all heard of the saying “A healthy mind exists in a healthy body”. A Swedish study proved cardiovascular fitness can raise your verbal intelligence by 50%. “Increased cardiovascular fitness was associated with better cognitive scores,” says Maria Aberg, who led the study.
All in all, if the body is healthy it also means good circulation of blood to the brain which improves the brain function and so makes you smarter because of which your can improve your IQ.
