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.

13 Bad Habits You Need to Quit Right Away

13 Bad Habits You Need to Quit Right Away

Creating your productivity ritual — a routine that helps you to maintain a peak level of energy can get you the best out of your days.

Part of creating your productivity routine involves removing activities that drain you (what I call “kryptonites”), and that includes your bad habits.

Like it or not, bad habits are bad for you — mentally, physically, emotionally and even socially in some cases. While some bad habits are harder to quit than others, it doesn’t change the fact that you need to get rid of them. Here are 13 bad habits to quit right away:

1. Stress Eating

I used to be a serious stress eater. I would eat whenever I felt unhappy, stressed, disappointed, anxious, or even… happy! My eating had nothing to do with being hungry, and everything to do with using food to fill my emotional voids.

While eating would comfort me, this feeling was momentary and would disappear right after I was done eating. Instead, what I had left would be the same emotional void that triggered me to eat in the first place (be it unhappiness or stress), a 2,000 excess calorie intake over what I should have eaten for the day, and anger at myself for having stress ate.

I’ve since overcome stress eating. I have healthy eating habits and a healthy relationship with food today where I no longer use food as a tool to fill my emotions.

If you are a stress eater, don’t fret — here’s how to manage your stress better:

2. Nail Biting

Not only is nail biting unhygienic, it is also socially repelling, leads to dental problems like malocclusion of the anterior teeth,[1] potentially cause stomach problems,[2] and lead to severely deformed fingernails in the long run.

People who bite their nails tend to have shorter nails than the average person; their nail plates also experience scarring and may eventually become absent.[3]

Understand what triggers your nail biting behavior and replace it with another neutral to positive habit. Make habits to break habits.

For example, if you bite your nails when you are stressed, go for a walk or listen to music instead the next time you feel stressed.

3. Hanging out with Naysayers

We all know these people — people who play devil’s advocate to every idea you have and every goal you want to pursue. We are already our greatest self-critics, so it doesn’t help when there’s someone beside us, ever ready to pounce on what we say and tear it down.

Hang out less with these naysayers and spend more time with supportive people who share constructive feedback instead. You will be much happier this way.

4. Being with People Who Don’t Appreciate You

Haven’t all of us been in this situation before? Trying to please people who don’t appreciate us? Bending over backwards to be there for people when they are never there for us?

While we give without expectations of return, we need to draw a line with people who don’t value us because these people damage our souls.

Stop spending time with people who don’t appreciate you, and spend more time with people who do instead.

5. Smoking

Smoking is one of the leading causes of preventable death globally.[4]

In just the United States alone, about 500,000 deaths are attributed to smoking-related diseases annually. A recent study estimated that as much as one-third of China’s male population will have significantly shortened life-spans due to smoking! Gender-wise, male and female smokers lose an average of 13.2 and 14.5 years of life respectively — that’s over a decade of life right there.[5]

Not only that, smoking causes pre-mature skin aging (i.e. wrinkles), yellowing of teeth, bad breath, and worse of all — jeopardy of the health of people around you, including your loved ones. Studies have shown that non-smokers exposed to second-hand smoke are at risk to many of the health problems associated with direct smoking.[6]

    6. Excessive Drinking

    All of us know that drinking too much alcohol is bad for us, but do you know how bad it really is?

    Advertising

    According to the National Institute on Alcohol Abuse and Alcoholism, drinking too much — be it on a single occasion or over time — can seriously damage your health:[7]

    • Brain problems: Alcohol interferes with the brain’s communication pathways, making it harder to think clearly and move with coordination.
    • Heart diseases: Cardiomyopathy – Stretching and drooping of heart muscle, Arrhythmias – Irregular heart beat, stroke, high blood pressure
    • Liver diseases: Steatosis or fatty liver, alcoholic hepatitis, fibrosis, cirrhosis
    • Pancreas problems: Pancreatitis, a dangerous inflammation and swelling of the blood vessels in the pancreas that prevents proper digestion.
    • Different types of cancer: Mouth, esophagus, throat, liver, breast

    If you drink a lot, perhaps cutting it out right away will be tough. Cut down the number of glasses you drink each time, followed by the number of times you drink a week.

    If need be, seek help from an AA group — you aren’t alone in this. Change starts from today.

    7. Eating Junk Food (Including Diet Soda)

    Junk food — they are everywhere in our society today. From McDonald’s, to KFC, to Burger King, to 24-hour takeouts, junk food such as fries, highly processed burgers and sodas has become a staple in our society today.

    If you think, “Hey, but junk food is tasty!”, think again:

    A study by Paul Johnson and Paul Kenny suggests that junk food consumption alters brain activity in a way similar to addictive drugs like cocaine and heroin.[8]

    “After many weeks with unlimited access to junk food, the pleasure centers of rat brains became desensitized, requiring more food for pleasure.”

    And you wonder why you seem to crave fast food when you just had some the day before?

    While it may not be possible to remove junk food completely from our diet right away, we can reduce our junk food consumption starting today. Instead of soda, opt for a fruit juice (fresh juice, not the carbonated kind) or mineral water. Instead of fries, switch to mashed potato, a salad, or rice (many food outlets allow for this today). Instead of a fried meat patty, go for a grilled one.

    Where possible, opt for healthy food joints like salad bars and delis as opposed to fast food outlets. Every little step goes a long way.

    8. Eating Too Much Red Meat

    There has been conclusive evidence that consumption of red meat increases the risk of colorectal cancer; and suggestive evidence that it increases the risk of oesophageal cancer, lung cancer, pancreatic cancer, and endometrial cancer.

    Advertising

    In addition, some studies have linked consumption of large quantities of red meat with breast cancer, stomach cancer, lymphoma, bladder cancer, lung cancer and prostate cancer![9]

    Personally, I’m a vegetarian so I don’t consume red meat, but for those of you who consume red meat, do watch out and limit your intake — better still, cut it out of your diet. World Cancer Research Fund recommends limiting intake of red meat to less than 300g (11 oz) cooked weight per week, “very little, if any of which to be processed.”

    9. Watching Too Much TV

    I stopped watching TV since eight years ago and I have never regretted it. Every once in a while I will switch on the telly to see what is on, and then I will switch it off because it’s just the same boring shtick over and over again.

    Watching TV, particularly well-written dramas, can be a good way to unwind. However, remember that TV isn’t your life.

    Spending three hours every night watching TV will not change your life for the better. Rather, using that time to reflect on your life, take stock, and take action on your goals will.

    It’s not easy to remove TV from your daily routine right away, but follow these 6 Steps To Remove TV From Your Life.

    10. Being Late

    Not only is being late being rude to others, it also means that you’re always rushing from one place to another, playing catch up in your agenda, and having to apologize to every person you meet.

    Stop being late and not being punctual, but practice being early instead. Target to arrive 15 minutes earlier before any appointment and bring along something to do in those 15 minutes (or longer if the other person turns out to be late). Then you can stop playing catch up and stay ahead in life.

    11. Being in Bad Relationships

    Are you always dating the wrong guys/girls? Do you end up with jerks all the time? Well, you may not be able to stop yourself from meeting bad partners but you can certainly stop yourself from furthering contact with them, spending time with them, or even… entering into a relationship with them.

    I used to invest myself in this guy who was nothing but toxic for me. After a good five months of experiencing nothing but getting burned over and over again, I realized that he was a total waste of my time and I deserved better. I decided to cut him off, and it was soon after that I met my soulmate.

    12. Leaving Things to the Last Minute

    Burning the midnight oil isn’t fun — it’s exhausting.

    Those of you who got through college by burning the midnight oil would have learned this the hard way. Not only is it damaging for your body, it is also mentally draining as you’re constantly in a hyper-tense mode, feeling anxious about whether you can finish your work on time.

    Start today on a new note. Rather than react to your deadlines, be proactive about them by planning ahead, identifying what needs to be done for the week, and getting things done in advance.

    By staying ahead of your tasks, you can also use your extra time to plan ahead in your life and get more things done.

    13. Focusing on the Negatives

    In every situation, there are two ways you can react: zoom down to the problem areas and crib about how things aren’t the way you want, or celebrate the areas that are going well and work on making everything better.

    Many of us see the importance of doing the latter but in practice, we do the former. Why though? Criticizing and focusing on the negatives is easy but it doesn’t empower nor inspire us to be better.

    Make a change — for every negative encounter you run into, I challenge you to identify three things that are good about it. Practice doing this for one week, and by the end of the week you’ll find that your first instinct is to think positive, not negative.
