Being lucky enough to look out over a green space from our City office, I have to agree that it helps when trying to concentrate on a difficult email or working on a budget spreadsheet.
Our findings suggest that engaging in these green microbreaks—taking time to look at nature through the window, on a walk outside, or even on a screen saver—can be really helpful for improving attention and performance in the workplace.
