Fewer distractions allow for deeper concentration, enhancing comprehension and retention of material. Studies suggest that the brain is particularly receptive in the morning, which can lead to improved information processing and quicker understanding of complex topics. Moreover, establishing a routine early in the day fosters discipline and consistency, attributes essential for the extensive syllabus of the UPSC examination.
