Why Is It Important for Adults to Do Riddles?
As mentioned above, regularly engaging in brain teasers is a great way to boost your critical thinking skills and creative abilities. Researchers have gone so far as to suggest that puzzles can actually preserve cognitive function among individuals suffering from cognitive decline.
And that's not even the best part. Besides keeping our brains sharp, riddles can make us incredibly joyful. Seriously.
Do you know that "aha!" moment you experience when you finally get to the bottom of whatever brain teaser you're working on? Well, fMRI machines have actually been able to capture what happens in the brain during this time.
According to a 2018 study published in the Journal of Human Brain Mapping, finally finding a solution to whatever you're working on results in a rush of dopamine to the nucleus accumbens, the area of the brain responsible for rewards and reinforcement.
With that, we can determine that the best riddles out there don't just keep you sharp—they also leave you extremely satisfied.
