“Throughout the workday, people expend high levels of cognitive resources to complete their work,” says Russell E. Johnson, a professor of management at Michigan State University’s Broad College of Business. “These cognitive resources are needed to focus attention, block out distractions, work through problems, and regulate emotions and stress.”

But the resources aren’t endless. They deplete as the day progresses, depending on how mentally challenging the work and environment is. Cognitive resources can be replenished through mental respites. While taking short breaks during the day helps, the most important time of day to recharge is in the evening after the workday had ended, says Johnson.
