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.

How to Improve Memory and Boost Your Brainpower

How to Improve Memory and Boost Your Brainpower

Have you ever noticed that some people are able to effortlessly remember even the most mundane details and quickly comprehend new things? Well, you can too!

To unlock the full potential of your brain, you need to keep it active and acute. Wasting time on your couch watching mindless television shows or scrolling through facebook is not going to help.

Besides getting out flashcards, what can you do to help remember things better and learn new things more quickly? Check out these 10 effective ways on how to improve memory:

1. Exercise and Get Your Body Moving

Exercising doesn’t just exercise the body, it also helps to exercise your brain. Obesity and the myriad of diseases that eventually set in as a result of being overweight can cause serious harm to the brain.

Furthermore, without regular exercise, plaque starts to build up in your arteries, and your blood vessels begin to lose the ability to effectively pump blood. Plaque buildup leads to heart attacks and it also reduces the amount of oxygen and nutrients that your blood carries to your brain. When the nutrients don’t make it there, the brain’s ability to function is compromised.

To prevent this from happening, make sure you get moving every day. Even if it’s just a brisk walk, it’ll help you maintain and increase your mental acuity. Brisk walking, swimming and dancing are all excellent activities. Take a look at these 5 Ways to Find Time for Exercise.

2. Eliminate Stressors and Seek Help If You’re Depressed

Anything that causes you major stress, like anger or anxiety, will in time begin to eat away the parts of your brain that are responsible for memory. Amongst the most brain-damaging stressors is depression, which is actually often misdiagnosed a a memory problem since one of its primary symptoms is the inability to concentrate.

If you can’t concentrate, then you might feel like you are constantly forgetting things. Depression increases the levels of cortisol in your bloodstream which elevates the cortisol levels in the brain. Doctors have found that increased cortisol diminishes certain areas of the brain, especially the hippocampus which is where short-term memories are stored.

Prolonged depression can thus destroy your brain’s ability to remember anything new. Seek professional help to combat your depression – your brain will thank you.

3. Get a Good Night’s Sleep and Take Naps

Getting a consistent 7 to 8 hours of sleep each night will increase your memory. During sleep, the brain firms up memories of recently acquired information.

Getting enough sleep will help you get through the full spectrum of nocturnal cycles that are essential to optimal brain and body functioning during the waking hours. Taking a nap throughout the day, especially after learning something new, can also help you to retain those memories as well as recharge your brain and keep it sharper longer.

4. Feed Your Brain

Fifty to sixty percent of the brain’s overall weight is pure fat, which is used to insulate its billions of nerve cells. The better insulated a cell is, the faster it can send messages and the quicker you will be thinking.

This is precisely why parents are advised to feed their young children whole milk and to restrict dieting – their brains’ need fat to grow and work properly. Skimping on fats can be devastating even to the adult brain.

Thus, eating foods that contain a healthy mix of fats is vital for long-term memory. Some excellent food choices include fish (especially anchovies, mackerel and wild salmon) and dark leafy green vegetables. Here’re more brain food choices: 12 Foods that Can Improve Your Brain Power

Deep-fried foods obviously contain fat but their lack of nutritional value is not going to help your brain or your body, so think healthy foods and fats.

5. Eat Breakfast and Make Sure It Includes an Egg

According to Larry McCleary, M.D., author of  The Brain Trust Program, an egg is the ideal breakfast. Eggs contain B vitamins which help nerve cells to burn glucose, antioxidants that protect neurons against damage; and omega-3 fatty acids that keep nerve cells firing at optimal speed.

Other foods to add to your breakfast include fruits, veggies and lean proteins. Avoid trans fats and high fructose corn syrup. Trans fats diminish the brain cells’ ability to communicate with each other and HFCS can actually shrink the brain by damaging cells.

Having a healthy breakfast in the morning has been shown to improve performance throughout the day. If you’re too busy to have a healthy breakfast, this maybe just right for you: 33 Quick And Healthy Breakfasts For Busy Mornings

6. Write it Down

If there’s something you want to remember, writing it down can help.

It may sound like a no-brainer, but do you really know why? Writing it down creates oxygenated blood flow to areas of your brain that a responsible for your memories and literally exercises those parts of it. Here’s How Writing Things Down Can Change Your Life.

You can start a journal, write yourself emails or even start keeping a blog – all of these activities will help to improve your capacity to remember and memorize information.

7. Listen to Music

Research shows that certain types of music are very helpful in recalling memories. Information that is learned while listening to a particular song or collection can often be recalled by thinking of the song or “playing” it mentally. Songs and music can serve as cues for pulling up particular memories.

8. Visual Concepts

In order to remember things, many people need to visualize the information they are studying.

Pay attention to photographers, charts and other graphics that might appear in your textbook; or if you’re not studying a book, try to pull up a mental image of what it is you are trying to remember. It might also help to draw your own charts or figures, or utilize colors and highlighters to group related ideas in your notes.

9. Teach Someone Else

Reading material out loud has been shown to significantly improve memory of the material. Expanding further upon this idea is the fact that psychologists and educators have found that by having students teach new concepts to others, it helps to enhance understanding and recall.

Teach new concepts and information to a friend or study partner, and you’ll find you remember the information a lot better.

10. Do Crossword Puzzles, Read or Play Cards

Studies have shown that doing crossword puzzles, read or play cards on a daily basis not only keep your brain active but also help to delay memory loss, especially in those who develop dementia.

So pick up the daily newspaper and work on that crossword puzzle, read a book or enjoy a game of solitaire.

Pick one to two of these tips first and start applying them to your everyday life. Very soon you’ll find yourself having better memories and a clearer head!
