40-Hour Work Week Is Linked To Cognitive Decline, Study Says

40-Hour Work Week Is Linked To Cognitive Decline, Study Says

Earlier this summer, a study focusing on the link between 40-hour work weeks and cognitive decline was published, and it’s got a lot of people thinking.

The study, which was first reported by Science Alert and then picked up by various outlets, showed that people over the age of 40 actually suffer from 40-hour work weeks. Cognitive decline was significant in those that worked what we now consider to be the common work week of eight hours a day, five days a week. In fact, working anything more than a 25-hour work week was deemed to be detrimental to the workforce.

But before you ask for a new work schedule, let’s go over the study and find out what it all means.

The Study

The BBC reports that the study was conducted by researchers at the Melbourne Institute of Applied Economic and Social Research in Australia. The study had over 6,500 participants, with over 60% of them being women. All participants were aged 40 and over, held jobs, and had different work schedules. This included people who worked part time and people who worked full time.

How the results were measured came in the form of three separate tests, all of which tested a cognitive ability. The three main tests focused on memory, reading, and perceptive ability.

What remains unclear, however, is exactly how this study was carried out. While it is assumed that the participants were given the tests at specific intervals and during different weeks, the actual method remains a mystery.

The Results

The results, however, were crystal clear — researchers found that participants in the study that worked part time, or around 25 hours a week, showed no signs of cognitive decline when compared to those who worked full time. It is also interesting to note that participants who worked less than 25 hours a week also showed low cognitive scores, which pinpoints 25 hours as the perfect work week for everyone.

This might come as a surprise to you, especially since the common work week is nearly twice as long as the new ideal work week. But it can be explained using a few key factors that I’ll share with you below.

Stress, Lack of Sleep, and How it Affects Cognitive Function

It’ll come as no surprise that stress affects cognitive functioning, especially at work. This is because stress has been known to contribute to neuron loss in the brain. This is an important factor to keep in mind because more studies are needed to understand how stress inflames cognitive decline for people working full time.

A lack of sleep is also considered to be a factor in cognitive decline. As we age, a suitable amount of sleep is needed to keep us at our best. But studies have begun to show that pulling all-nighters or working overtime decreases the white matter in the brain, which leads to cognitive decline.

A Word on White Matter

White matter is a phrase that comes up in a lot of cognitive decline studies, and it came up in this study as well. It refers to the pathways neurons use in our brain for communication, language, memory, perception, and more. It’s a vital factor in cognitive function.

When humans age, white matter decreases as the brain shrinks. But in people who are working overtime and aren’t getting enough sleep, the white matter decreases at a significant rate. This is a preventable problem, so make sure you get as much sleep as you need in order to be your best self at work.

The Takeaway

This study showed that people over the age of 40 are at the risk of cognitive decline when working a 40-hour work week. However, this study only focused on that age group and did not produce results for people aged 18-40, so the results are very specific.

The takeaway is this: As humans, are we willing to risk a decline in cognitive and brain function to work full time?

This is an important question to raise. In many first-world countries, 40-hour work weeks are the norm, and as many governments raise the level for retirement — which is when various social services become available — there are serious questions raised about the workforce’s ability to operate at a high cognitive function.

But it also brings up another point: If 40-year-olds are this affected by the work week, are people under the age of 40 at risk also? Professionals often have families, which gives them extra jobs, extra stress, and could lead to some sort of cognitive decline. We will have to wait and see as new studies are conducted in this area.

As a freelance writer who works full-time, this study was interesting in that it focused on the actual consequences that working has on the brain. It’s also led me to take into serious consideration how France and Sweden are handling the new information, with both countries taking steps to lower the work-week demands for their citizens. Switzerland also has a shorter work week when compared to Western companies.

Most of all, it has caused me to look back on my own work practices. While I can control my own stress and lack of sleep, my work schedule is something else entirely. But since I’m a freelancer, I have a freedom most don’t — I can set my own hours.

For anyone who’s reading this that works 40 hours a week, it might be time to think about making a change when it comes to your career. Learn about flexible work hour options, which many organizations are introducing, and take your vacation days. You’ve earned them.

But most of all, take the time to care for yourself. No job is worth losing cognitive function.

The 10 Essential Habits of Positive People

The 10 Essential Habits of Positive People

Are you waiting for life events to turn out the way you want so that you can feel more positive about your life? Do you find yourself having pre-conditions to your sense of well-being, thinking that certain things must happen for you to be happier? Do you think there is no way that your life stresses can make you anything other than “stressed out” and that other people just don’t understand?  If your answer is “yes” to any of these questions, you might find yourself lingering in the land of negativity for too long!

The following are some tips to keep positive no matter what comes your way. This post will help you stop looking for what psychologists call “positivity” in all the wrong places!  Here are the ten essential habits of positive people.

1. Positive people don’t confuse quitting with letting go.

Instead of hanging on to ideas, beliefs, and even people that are no longer healthy for them, they trust their judgement to let go of negative forces in their lives.  Especially in terms of relationships, they subscribe to The Relationship Prayer which goes:

 I will grant myself the ability to trust the healthy people in my life … 

To set limits with, or let go of, the negative ones … 

And to have the wisdom to know the DIFFERENCE!

 2.  Positive people don’t just have a good day – they make a good day.

Waiting, hoping and wishing seldom have a place in the vocabulary of positive individuals. Rather, they use strong words that are pro-active and not reactive. Passivity leads to a lack of involvement, while positive people get very involved in constructing their lives. They work to make changes to feel better in tough times rather than wish their feelings away.

3. For the positive person, the past stays in the past.

Good and bad memories alike stay where they belong – in the past where they happened. They don’t spend much time pining for the good ol’ days because they are too busy making new memories now. The negative pulls from the past are used not for self-flagellation or unproductive regret, but rather productive regret where they use lessons learned as stepping stones towards a better future.

4. Show me a positive person and I can show you a grateful person.

The most positive people are the most grateful people.  They do not focus on the potholes of their lives.  They focus on the pot of gold that awaits them every day, with new smells, sights, feelings and experiences.  They see life as a treasure chest full of wonder.

5. Rather than being stuck in their limitations, positive people are energized by their possibilities.

Optimistic people focus on what they can do, not what they can’t do.  They are not fooled to think that there is a perfect solution to every problem, and are confident that there are many solutions and possibilities.  They are not afraid to attempt new solutions to old problems, rather than spin their wheels expecting things to be different this time.  They refuse to be like Charlie Brown expecting that this time Lucy will not pull the football from him!

6. Positive people do not let their fears interfere with their lives!

Positive people have observed that those who are defined and pulled back by their fears never really truly live a full life. While proceeding with appropriate caution, they do not let fear keep them from trying new things. They realize that even failures are necessary steps for a successful life. They have confidence that they can get back up when they are knocked down by life events or their own mistakes, due to a strong belief in their personal resilience.

7. Positive people smile a lot!

When you feel positive on the inside it is like you are smiling from within, and these smiles are contagious. Furthermore, the more others are with positive people, the more they tend to smile too! They see the lightness in life, and have a sense of humor even when it is about themselves. Positive people have a high degree of self-respect, but refuse to take themselves too seriously!

8. People who are positive are great communicators.

They realize that assertive, confident communication is the only way to connect with others in everyday life.  They avoid judgmental, angry interchanges, and do not let someone else’s blow up give them a reason to react in kind. Rather, they express themselves with tact and finesse.  They also refuse to be non-assertive and let people push them around. They refuse to own problems that belong to someone else.

9. Positive people realize that if you live long enough, there are times for great pain and sadness.

One of the most common misperceptions about positive people is that to be positive, you must always be happy. This can not be further from the truth. Anyone who has any depth at all is certainly not happy all the time.  Being sad, angry, disappointed are all essential emotions in life. How else would you ever develop empathy for others if you lived a life of denial and shallow emotions? Positive people do not run from the gamut of emotions, and accept that part of the healing process is to allow themselves to experience all types of feelings, not only the happy ones. A positive person always holds the hope that there is light at the end of the darkness.  

10. Positive person are empowered people – they refuse to blame others and are not victims in life.

Positive people seek the help and support of others who are supportive and safe.They limit interactions with those who are toxic in any manner, even if it comes to legal action and physical estrangement such as in the case of abuse. They have identified their own basic human rights, and they respect themselves too much to play the part of a victim. There is no place for holding grudges with a positive mindset. Forgiveness helps positive people become better, not bitter.

How about you?  How many habits of positive people do you personally find in yourself?  If you lack even a few of these 10 essential habits, you might find that the expected treasure at the end of the rainbow was not all that it was cracked up to be. How could it — if you keep on bringing a negative attitude around?

I wish you well in keeping positive, because as we all know, there is certainly nothing positive about being negative!
