A deadline is approaching. The assignment is unfinished. You open your laptop, check your phone, promise to start in five minutes, and somehow lose an hour. For millions of college students, this familiar cycle may be doing more damage than they realise.
A study of 65,950 students across 97 US higher education institutions has found that procrastination was the most common problem reported by students and the issue most frequently linked to poorer academic performance.
Published in PLOS One on October 7, 2026, the study compared procrastination with 35 other life and health issues, including financial problems, anxiety, depression, ADHD and sleep difficulties.
PROCRASTINATION IS MORE THAN A BAD HABIT
The findings are striking. As many as 72.3% of students reported experiencing procrastination in the previous 12 months, putting it almost level with stress, reported by 73.8%.
More importantly, 45.4% of all students said procrastination had negatively affected their academic performance. Among students who experienced procrastination, the figure rose to 62.7%.
The academic impact was considerably higher than that reported for financial problems, which affected 16.1% of the overall sample, or ADHD, which affected 12.9%.
This does not mean procrastination is more serious than ADHD for an individual student. Rather, it shows how widely delayed action can interfere with academic work across a student population.
UNDERGRADUATES STRUGGLE MORE
Undergraduate students reported greater problems with procrastination than those pursuing graduate and professional degrees.
Among undergraduates, 74.8% reported procrastination, compared with 66.2% of graduate and professional students. Nearly half of undergraduates, 49.3%, said it harmed their academic performance. Among graduate and professional students, the figure was 35.1%.
Procrastination was also linked to significant distress. Overall, 45.7% of students said it caused them significant distress, making it the leading life-related issue on this measure.
WHY PUTTING THINGS OFF CAN BACKFIRE
The study does not establish that procrastination directly causes every reported academic problem. It relies on students’ own responses, and the findings may not represent every US college student or apply directly to students in India.
However, the researchers point to a familiar cycle: delaying an assignment can increase stress, disrupt sleep and make it harder to begin the task later.
Breaking assignments into smaller steps, reflecting on avoidance patterns and building better self-regulation habits are among the approaches educators can use to help students act earlier.
The message is not that students simply need to try harder. When putting things off becomes a repeated pattern, understanding why it happens may be just as important as meeting the next deadline.
