Regardless of whether people call this experience the Sunday scaries (Sunday evening feeling and Sunday syndrome are two alternatives), a lot of them undergo some variation of it. A 2018 survey commissioned by LinkedIn found that 80 percent of working American adults worry about the upcoming workweek on Sundays. Another survey by a home-goods brand found that the Sunday scaries’ average time of arrival is 3:58 p.m., though they seem to set in later than that for many people. (A cousin of the Sunday scaries is the returning-from-vacation scaries, which can fall on any day of the week.)

“This feeling, whether we call it anxiety, worry, stress, fear, whatever, it’s all really the same thing,” says Jonathan Abramowitz, a clinical psychologist and professor at the University of North Carolina at Chapel Hill. “Psychologically, it’s a response to the perception of some sort of threat.” The perceived threat varies—it might be getting up early, or being busy and “on” for several days in a row—but the commonality, Abramowitz says, is that “we jump to conclusions” and “underestimate our ability to cope.” For most people, he reckons, the stress of Sunday is uncomfortable but ultimately manageable—and they end up coping just fine. (And just as with other forms of anxiety, some people don’t feel the Sunday scaries at all.)
