For a Sudoku to be solved, you need to be able to learn, reason and remember numbers. Most of which has to do with the term “cognition” (click the word above for a precise terminology).
I learned about my own cognitive condition from doing a lot of Sudoku the past years. For instance I learned that having poor sleeping over longer periods made my Sudoku solving ability very poor. Also if I was plainly tired from a long day, my Sudoku skills suffered. Other things that made Sudoku hard for me to solve was the (for the time being) ever present fatigue, tinnitus and level of blood sugar.
After I became quite skilled in Sudoku, I recognized variations in my own mental performance. And soon it became apparent to me that my mental performance also followed certain patterns. And this is the interesting part that made me want to share this with my readers.
Sudoku taught me when I was tired in a time where I was always tired, if that makes sense??? It’s the fatigue-thing I’m talking about… How did THAT help me? Well, there was variations of tiredness over time. Some days I just couldn’t remember from 5 minutes earlier, or I had trouble concentrating on the task at hand (I have a special routine for solving them). And since I was all about getting better, noticing the good or bad days for Sudoku gave me an external method of measurement of my mental state in a period where my own built-in sensor needed calibration, so to speak 🙂
Sudoku taught me how to trust and USE my own sense of tiredness again. The feeling of tiredness is a signal to ourselves to slow down, to take a break, to eat and drink, to sleep or take a nap and so on…
Yes, I was truly f***ed up, I had lost the ability to heed the signals my own body and mind gave me… Sudoku helped me almost in a scientific way to regain that.
I continue to do Sudoku, allthough not as much as I used to, but it is still a fine tool for measuring my own cognitive skills. And I can recommend Sudoku to everyone as mental training. It has been and continues to be useful to me, not only as a tool for mental measurement but also as hobby that trains my cognitive skills somewhat… And we all could do with better brains, right?
