Sleep Critical to Memory Retention

We’ve reported on this in the past……however more information is available. According to a new study in the Feb. 2 issue of The Journal of Neuroscience, during sleep the brain preferentially retains the memories that are most relevant. Researchers set up two experiments to test memory retrieval. In the first experiment, people were asked to learn 40 pairs of words and in the second, participants played a card game where they matched pictures of animals and objects. In both groups, half the volunteers were told that they would be tested in 10 hours. However, all participants were tested later on how well they recalled their tasks.

It turned out that the people who slept and knew a test was coming had substantially improved memory recall. Sleep was critical to memory enhancement. There was an increase in brain activity during deep or “slow wave” sleep in those volunteers knew they would be tested for memory recall.

This should interest managers caring that employees retain on the job and other training. Safety, human resource, and facility managers might consider fatigue management training to ensure employees are fully aware of the benefits of sleep for themselves and the workplace.

The researchers think that the brain’s prefrontal cortex focuses on memories viewed as relevant while awake and the hippocampus consolidates these memories during sleep.

This is another study that points to the importance sleep to memory retention – something shift workers and their managers should really care about.

Shift Workers Save Each Other – the Chilean Rescue Tale

All around the world people are celebrating the rescue of the 33 Chilean miners trapped underground for ten long weeks. And, at Working Nights we’re celebrating too! Like everyone else, we’re ecstatic that the trapped miners were brought to safety. But we’re also celebrating from a shift worker perspective! This is a story about the good that happens when shift workers join together to help other shift workers. This tale is a collaboration of shift workers – from all walks of life – miners, government workers from multiple countries, small business men from the U.S. and Chile, and others.

In this case, employees from Layne Christianson Co., whose largest business is drilling water wells, and Geotec Boyles, SA, Lane Christianson’s partner in Chile, worked round-the-clock for 33 days to save the trapped miners. The miners were buried nearly 2,300 feet underground after a cave-in. The Layne/Geotec workers drilled a 2,300-foot tunnel that was 28 inches in diameter; it was large enough for the 26-inch rescue capsule to fit through. Others were working 24/7 as well. NASA designers worked with the Chilean Navy to design the 13 foot long, 925 pound rescue capsule which the Chilean’s named Phoenix.

Achieving success took whole-hearted co-operation among all parties involved, starting with the miners themselves. These 33 men lived on rations normally meant to sustain them for no more than two or three days. Under the extraordinary leadership of their foreman, the men shared what little they had. They shared the conviction that each man’s survival depended on all of the others down there surviving too. The miners’ only contact with the outside world was through tiny drill holes used to send down food, water, medicine and games.

Agriculture, forestry, fishing, hunting, and mining workers have historically worked long hours in difficult conditions. But 33 days straight takes the cake! Hopefully all shift workers that participated in this rescue, and all people working shift work will celebrate this great accomplishment.

Getting on the Right Team

So much of work these days is team–based, requiring groups of diverse people to work together on complex or risky initiatives. Consider the challenges that shift working groups face – like workers overseeing our nuclear power safety, emergency medical teams, miners working deep underground, shift workers on oil rigs around the world…..How can work be any more complex or risky than in these environments?

A recent study co-authored by MIT, Carnegie Mellon University, and Union College researchers, and published Sept. 30, in the advance online issue of the journal Science, addresses the cognitive capabilities of a team, as opposed to the intelligence of individuals. The study found that collective intelligence among groups of people who cooperate well is linked to the number of women in the group. The researchers reported that groups whose members had higher levels of “social sensitivity” were more collectively intelligent. The teams containing more women demonstrated greater social sensitivity and in turn greater collective intelligence.

So what is meant by the term socially sensitive? In the case of this study, it meant discerning emotions from looking at people’s faces. For an excellent book that will help you to improve your ability to read people’s faces, look up Emotions Revealed by psychologist Paul Ekman. The book shows how the following emotions are revealed through facial expression (including photos!).
1. Grief, sadness
2. Anger
3. Surprise
4. Contentment, Enjoyment, sensory pleasures
5. Fear
6. Disgust, contempt

Interestingly, the average and maximum intelligence of individual group members did not significantly predict the performance of their groups overall. Having a lot of smart people in the group didn’t automatically cause the group to rise to the top. In the study, 699 people were placed in groups with two to five members. The groups worked together on tasks ranging from puzzles to negotiations, brainstorming, games and complex rule-based assignments. Only later, when analyzing the data, did the researchers notice that the number of women in a group seemed to predict higher functioning teams.

Obviously, many men are also socially sensitive. The study researchers stated that they believed that having group members with higher social sensitivity is better regardless of whether they are male or female. Perhaps it would be good to study the social sensitivity of shift workers. After adjusting for the impact of sleep deprivation, shift workers are probably a pretty socially sensitive group. After all, it takes a certain amount of social smarts to work 24/7 and stay safe and healthy and connected with family and friends. And, these jobs do require a heightened amount of teamwork for success.

New Shift Work Information on Weight Loss and Apnea, Craving a Smoke, and the Combined Effects of Caffeine and Alcohol

During the last month three new studies potentially impacting a number of shift workers have been released. Here are the top level findings:

1. A dramatic weight loss can improve moderate to severe sleep apnea in obese men.

2. Craving a cigarette while performing a cognitive task increases the chances of a person’s mind wandering and they don’t even realize it is happening.

3. Drinking a cup of coffee may actually make it harder for people to realize they’re drunk.

Read on to understand why these are important studies for shift workers.

The Connection Between Safety and Teamwork – It’s all about Communication and Taking Workers’ Individual Differences into Account!

Starting as young children, we’re taught about the importance of teamwork.  For example, we might have learned to work together to bring the groceries in from the car – maybe one person brought the bags into the house, another took them into the kitchen, another unpacked them, and someone else put the food away in the cabinets and fridge.  It felt fun working together at something; the experience was certainly more enjoyable than anyone doing the whole job on their own.  And, we could see that this four person exercise accomplished the task in a quarter of the time it would take one person to do the whole thing (if you were lucky enough to have four people to pitch in and help!).

Ralph Waldo Emerson said, “No member of a crew is praised for the rugged individuality of his rowing.”  

As adults we’re told that teamwork is critical to achieving success in our jobs too.  But, is this really the case?

Yale Murder Highlights Workplace Violence Risks

According to The Occupational Safety and Health Administration (OSHA), two million Americans are subject to workplace violence each year. Defined as a threat of violence or an actual violent action taken against workers, some recent cases have heightened concerns about workplace violence. The Bureau of Labor Statistics (BLS) data indicates that fatal occupational injuries due to assaults and violent acts were actually down 8% between 2007 and 2008 (864 in 2007 to 794 in 2008). But, during the same period, office suicides reached an all time high since the data has been captured by the BLS (251 in 2008 compared to 196 in 2007) – a 28% increase.

In January 2009, a survey of risk security practitioners by Security Director News found that despite all the recent focus on terrorism, 49% reported that workplace violence topped their security concerns.

Which workplaces are the most violent and how can we make all of our workplaces more safe?

Safety at Work for an Aging Population of Workers

Everywhere we turn there are articles about more seniors in the workforce. This is not a new trend, but the pattern has clearly stepped up as a result of the current recession. According to the Bureau of Labor Statistics, between 1977 and 2007, total employment in the US increased by 59%. Amazingly, employment of workers 65 and over had already increased 101% during this time! For men over 65, the 1977 to 2007 increase was 75%, but for women it was 147%. What does this mean for safety at work? We have a lot to do!

Learning from Past Mistakes about Managing Overtime after a Recession

After the last recession was over in 2002, overtime spiked at many extended hours operations and so did accidents and injuries on the job. After a recession, managers are usually gun-shy about hiring and for good reason – they want to feel confident that demand is truly back so they don’t generate oversupply. There are starting to be some early signs of improvement in the current economic climate, which means we may see overtime starting to creep up soon. Now’s the time to start planning in order to prevent accidents and injuries resulting from overtime.

Preventing Accidents and Injuries at Work

Besides general health risks, shift workers also face a wide range of faster-acting dangers. Every seven seconds another worker gets injured, and every day, machinery accidents, falls, crashes, and other accidents take lives. Older workers and minority workers face higher injury and fatality rates. Read here the startling facts about on-the-job death and injury, the financial and health costs, the facts of why accidents happen and tips for making work a safer place. Read this article…

The Expensive Recession: Managing Costs During Difficult Financial Times

Money’s low, stocks are down, workers and employers on all sides of the board are struggling to make ends meet. In this recession people are counting on their jobs more than ever, yet many companies view layoffs as the quickest way to get out of the red. But by focusing on root causes of money loss, management can make long-term changes to boost the profit of operations. Shift worker absenteeism bleeds company money, and frequent worker turnover requires more basic worker training and more money hunting for replacements. Increased preventative health care and management training would cut down on illness and injury, saving money on health costs and reducing absenteeism, as well as helping workers feel more connected with the company to slow worker turnover. This article focuses on the personal pain of layoffs and alternative ways to cut costs while saving jobs. Read this article…

The Importance of Training for Sustainable, High Performance Shift Work

Accidents, safety risks, and human error plague shift work at all hours of the day and night. Many managers see these dangers as a necessary evil that rides along with workers on shifts, especially rotating shifts and night shifts. Productivity also sinks as the shifts run into the late night/early morning hours, and extended hours workers take far more time off for illness than normal hours workers. This article shows specific ways that training managers together with shift workers raises productivity, decreases worker absences, and improves worker adaptation to the shift and night work lifestyle.

Improving Workplace Safety and Security

As if shift work’s threat of injury, increased rates of obesity, heart disease, and diabetes weren’t enough, as well as the potential for cancer hanging over your head, it turns out shift work can kill you much faster than any of those options. The good news is that taking care for your safety, simply paying attention, and getting enough sleep so drowsiness doesn’t hit you at the wrong time can hugely lower your risks on the job. In fact, the danger that causes the most shift worker fatalities is something that almost every person- day worker, night worker, shift worker, or unemployed- does every day. This danger is simply driving on the highway. Other dangers include working with machinery and robbery and homicide, especially for people coming home after a night shift.
