Why people spend a lifetime dreading Mondays

…rather than creating a life where they don't notice it's Monday. What the research says.

"That's just life"

Most people would call this normal. Everyone hates Mondays. That's life.

It is one of the most repeated sentences about work, and it also turns out… it's not true.

When researchers at Stony Brook University and Gallup tracked the daily mood of about 340,000 Americans, Monday scores came out the same as Tuesday, Wednesday and Thursday. Monday itself was not worse.

But the participants did remember the days differently. When asked to look back, people remembered Monday as worse than it had been. The lead researcher, Arthur Stone, put it plainly: "Despite our global beliefs about lousy Mondays, we conclude that this belief should be abandoned."

The authors' own words for it: "Cultural myths may vastly over-emphasise actual day of the week mood patterns."

So Monday is not the problem… the belief about Monday is.

The body keeps the belief, even after the job is gone

Fascinatingly, the "Mondays suck" beliefs carry on long after people are done working on Mondays.

In 2025, a University of Hong Kong team followed 3,511 adults aged 50 and over in England. People who felt anxious on a Monday had 23 percent higher levels of the stress hormone cortisol two months later. Feeling anxious on a Wednesday or a Friday did not have the same effect.

The researchers expected retired people to be free of it. They were not. People with no job showed the same Monday pattern as people still working. The lead author, Professor Tarani Chandola, called Mondays a cultural "stress amplifier."

On an anonymous forum, a user asked this: Do sunday scaries ever go away?

I d gaf about work (I don't give a f*ck about work) and standups every day. In my mind 1.6m is enough for me to retire . 36 and have a humpback already

Research would answer: No… they don't. Because they were never actually the problem.

Why it never gets questioned

So, if Mondays aren't actually the problem, why does this belief still exist?

Three things keep it locked in place.

1. Existence Bias & Longevity Bias

The first reason is a well-studied tendency to trust whatever already exists. Psychologists Scott Eidelman and Christian Crandall call it existence bias. Across five experiments, people judged things as better and more right simply because they existed, and the longer something seemed to have been around, the more right it seemed: longevity bias.

Later research found that when a person is motivated to seek change, it removes the effect of longevity bias altogether.

2. Beliefs: This is just the way it is.

The second reason the belief never gets questioned is because it got hard-wired into the brain at an age the brain doesn't have the capacity to evaluate true vs false, so it takes in everything as a fact. At Strategic Stewardship, we call this the Belief Lock and it happens before the age of 12.

"Work is supposed to be hard. You don't have to like your job. Everyone hates Mondays."

Those "facts" become pathways in the brain, networks of neurons that decide what kind of working life you're allowed to have, without checking with you for consent.

3. Reinforcement.

The third reason is repetition from trusted sources. As we grow up we watch our parents groan about Mondays. As adults we watch our peers groan about Mondays. As we age, every time someone complains about a Monday and someone agrees in resignation, it reinforces this belief as permanent and weakens our agency.

We don't even talk to people who don't complain about Mondays because they don't operate in the same circles. So we assume they don't exist.

How to feel differently about Mondays

A University of Rochester study led by Richard Ryan followed 74 working adults, from construction labourers and secretaries to physicians and lawyers.

Their moods were better, their energy was higher and they had fewer aches from Friday evening to Sunday afternoon.

The change in behavior was… surprisingly… not about the weekend itself.

It was largely tied to two things: freedom to choose what you do, and spending time with people you care about.

The researchers concluded that when daily life, including work, offers those things, wellbeing stays steadier instead of rising and falling each week.

Again, simpler: when daily life includes choice about how to spend your time and who you spend time with, people feel better mentally and physically.

The effect was the same regardless of age, education, salary, marital status or hours worked.

That is how to build a life where you don't notice it's Monday.

You build a life based on your choices. On how you want to spend your time. On what YOU choose.

No need to burn the bridges down and risk your financial safety. But there is a need to start building a strategy to create a work life that you will still be happy with in 20 years.

The main obstacle is that the old beliefs are still present.

As long as "work is supposed to be hard" and "everyone hates Mondays" are treated as fact, your brain will create situations that make this true (that's its #1 job).

This isn't a life sentence. It's just biology, and it's changeable.

Start by locating these beliefs. What were you told about work before you were 12? Then clear them at the level of the neural network, where they are stored.
