Puzzles have several known benefits for the brain, many having to do with activity, memory, and intelligence. According to experts, when we do puzzles, our brain feels as though we are "hunting for information" (via Reader's Digest). While not all puzzles develop new information and understanding for those who are completing them, the finality of finishing the puzzle does activate several areas of the brain. 

In addition, different puzzles do different things for our brain. The left side of our brain is the logical side, while the right side of our brain is the creative side (via Good Net). When we do puzzles, we're often stimulating both sides of the brain, however depending on the type of puzzle, one may be more stimulated than the other. As well, certain puzzles can help foster memory receptors and problem-solving skills, which can help impact our short-term receptors. Additionally, some puzzles can help language and speaking development, like the ones used in early education. 

For those who use puzzles as a way to pass time and relax, puzzles can be an excellent way to produce serotonin and de-stress after a long day. Many find the intellectual stimulation and challenges to be soothing. Furthermore, focusing on one task can put the other, everyday stressors in our life on the back burner for the time being. So, the next time you are feeling overwhelmed, grab yourself a puzzle and see where it takes you!
