Focused practice can help restore concentration and sharpen cognitive skills. A senior lecturer and practicing psychologist at the SPbPU Institute of Humanitarian Aid Engineering Pedagogy, Psychology and Applied Linguistics explains that targeted exercises make the mind more agile and productive.
You can try activities that engage both hands, move around with your eyes closed, or write with your non-dominant hand. You might also redefine a familiar topic in a new way. These unconventional tasks stimulate dopamine release, which leads to a sense of satisfaction even with tasks that are normally tedious. The key is regular experimentation: tackle routine duties with a new approach, switch up the daily schedule, and reverse typical sequences of tasks.
Consistent daily practice can yield faster results, as the brain begins to operate more efficiently and with greater flexibility.
