Khaberni - A new study has revealed that feeling mentally alert can significantly boost what you accomplish in your day, as researchers found that clear and effective thinking equates to about 40 extra minutes of productive work.
The study, conducted by a team from the University of Toronto Scarborough and published in the journal Science Advances, tracked participants over 12 weeks to understand why people sometimes struggle to follow through with their plans.
The results showed that daily fluctuations in mental alertness are the key factor. On days when individuals feel more mentally focused, they are more capable of setting and achieving their goals, whether in study or in simple daily tasks like preparing dinner.
Cindri Hutchinson, Associate Professor of Psychology at the University of Toronto Scarborough and lead author of the study, said: "Some days everything goes great, and other days you feel like you're moving through fog. What we wanted to understand was why this happens, and how significant these mental fluctuations really are."
Mental alertness measures how clear a person's focus and how efficient their thinking is at any given moment. When high, it is easier for people to concentrate, make quick decisions, and get tasks done. When it is low, even simple activities may seem difficult.
Instead of comparing different people, the research team followed the same individuals over time, allowing them to see how changes within a single individual affect their daily success.
All participants were university students who conducted short daily tests to measure the speed and accuracy of their thinking, and reported on their goals, productivity, mood, sleep, and workload.
The results showed a clear pattern: on days when students were more alert than usual, they accomplished more goals and often aimed higher, especially in academic work. On days when their alertness was lower, even routine tasks became harder to accomplish.
These effects were consistent regardless of personality traits. Traits like persistence or self-control impact overall performance but do not prevent individuals from having less productive days.
Hutchinson adds: "Everyone has good days and bad days, and what we're capturing is what separates the good days from the bad ones."
One of the most significant findings of the study was the practical value of mental alertness. Through the analysis of cognitive performance over working hours, researchers estimated that being above or below your usual level of alertness can change your productivity by about 30 to 40 minutes a day, while the gap between your best and worst days can be about 80 minutes of work.
The study shows that mental alertness changes from day to day and is not a fixed state. It was found that students were more focused when they slept longer than usual, and also in the early morning hours, while their mental performance gradually declined as the day progressed. Additionally, the feeling of enthusiasm and focus increases alertness, while a depressed mood leads to its decline.
Workload showed a dual effect: working longer hours in one day was linked to increased alertness, suggesting people's ability to meet immediate demands. However, extended periods of exhaustion reduce mental alertness and make maintaining productivity more difficult.
Hutchinson explains: "You can work hard for a day or two and be fine, but if you continue working without rest for too long, you will pay the price later."
Although the study focused on university students, the results are applicable on a broader scale. Hutchinson points out three things that can be done to maximize mental alertness: getting enough sleep, avoiding long-term exhaustion, and finding ways to avoid the trap of depression.
