The Gen Z Sunday Scaries Start at 4:13 p.m. - And Are Changing What They Eat

New Lifesum research reveals how workplace anxiety spills over into eating, sleep, and mental well-being before Monday has even begun

Los Angeles, CA. — October 2026 — The “Sunday Scaries” — the anxiety people experience as they anticipate returning to work on Monday — may be affecting Gen Z workers long before the workweek begins. New research from global healthy eating platform Lifesum reveals that the average Gen Z worker’s Sunday Scaries begin at 4:13 p.m., peak at 5:17 p.m., and can spill over into how they eat, sleep, and spend their Sunday.

The findings come as workplace stress and mental health concerns remain high among younger workers. In the US, 48% of workers typically feel tense or stressed during their workday, while 37% say their work environment has a negative impact on their mental health (American Psychological Association).

The Sunday Scaries Start Before Dinner

For 74% of Gen Z, the Sunday Scaries hit between 3 p.m. and 9 p.m., starting at an average of 4:13 p.m. and peaking at 5:17 p.m. Their concerns include:

• 44% replay conversations or interactions from the previous week

• 41% worry about work situations they cannot control

• 35% feel guilty they have not been productive enough over the weekend

• 31% say their anxiety starts when they realize the weekend is “running out”

Emelie Fritz, Workplace Well-Being Director at Lifesum for Work, said: “For employees, Sunday should be protected as genuine recovery time, with space to switch off from work and reset before Monday. For employers, it’s about creating a workplace culture that supports healthy habits and respects boundaries outside working hours, rather than creating an expectation that people need to be ‘on’ before the workweek has even begun. Giving people that space to disconnect can support both well-being and a more focused start to the week.”

When Sunday Anxiety Becomes “Revenge Eating”

Among Gen Z workers experiencing Sunday work anxiety, 34% say they turn to what they describe as “revenge eating” — using foods they would normally limit as a reward or emotional release after a stressful workweek. Of those who use food to cope, 46% reach for sweet foods, 39% snack, and 31% choose takeout. Those experiencing higher levels of Sunday anxiety are 1.8 times more likely to use food to cope than those experiencing lower levels of anxiety.

The findings suggest that stress can influence not only what people eat, but why they eat. For some, food becomes a source of comfort or reward after a difficult week, shifting eating habits away from routine and toward emotional coping. This highlights how nutrition is connected to the broader well-being picture: stress can shape our eating habits, our relationship with food, and the everyday routines that help us nourish ourselves. The goal isn't to label particular foods as “good” or “bad,” but to understand how workplace anxiety can shape our relationship with food.

The Sunday Night Recovery Gap

Gen Z workers experiencing high levels of Sunday work anxiety are twice as likely to report disrupted sleep on Sunday night.

• 52% find it difficult to mentally switch off from work

• 41% lie awake thinking about Monday

• 37% continue checking their phones even when they want to be sleeping

When stress disrupts everyday routines, eating can become less consistent, too. Maintaining regular meals, choosing satisfying and balanced foods, and staying hydrated can help people meet their nutritional needs without adding more rules or pressure to an already stressful Sunday. Rather than striving for perfect eating habits, building a simple, sustainable routine can help make nutrition a positive part of the weekly reset.

What Helps Gen Z Switch Off

Spending time with friends or family helps ease Sunday anxiety for 62% of Gen Z workers, while 54% say walking or exercise helps. By contrast, 41% say scrolling through social media makes their anxiety worse, and 37% say checking work messages does the same. Those who set a clear cutoff for work communications are 1.6 times more likely to say their Sunday anxiety eases.

A better Sunday reset starts with making space to recover: disconnecting from work, spending time with others, and maintaining simple, nourishing routines. Food shouldn't become another source of stress, but a positive part of taking care of ourselves as the new workweek approaches.
