There is a common negative opinion about daydreaming, which is generally associated with inattentiveness, or lack of concentration, but a new study has claimed that daydreaming helps solving life’s more complex problems. The study by the Canadian researchers has found that the brain becomes more active during daydreaming.

The researchers scanned the brains of the study subjects lying inside magnetic resonance imaging (MRI) machines. They found that the "default network" deep inside a human brain became more active during daydreaming.

In the study published in the Proceedings of the National Academy of Sciences, the co-author of the study, and head of a neuroscience laboratory at the University of British Columbia in Western Canada, Kalina Christoff said, “Mind wandering is typically associated with negative things like laziness or inattentiveness, but this study shows our brains are very active when we daydream — much more active than when we focus on routine tasks.”

Christoff said, “When you daydream, you may not be achieving your immediate goal — say reading a book or paying attention in class — but your mind may be taking that time to address more important questions in your life, such as advancing your career or personal relationships.”
