This Is How Simply Changing The Lighting Can Make You Perform Better

This Is How Simply Changing The Lighting Can Make You Perform Better

We have all experienced, either consciously or subconsciously, the different effects that lighting can have on us: the disco light ball enhances the upbeat feeling we get on the dance floor, an entirely different atmosphere is created by a candle lit dinner. However, have you thought that lighting can affect your performance significantly?

In a study published in the journal Optics Express, Kyungah Choi and Hyeon-Jeong Suk look at the way lighting can boost student success in the classroom.

Research Background

In the preliminary and main study, Choi and Suk examined the effects of different correlated color temperatures (CCTs). The CCT characterizes the color of a given light source. A low CCT gives out a light that appears “warm” or yellowish white. A high CCT gives out a light that appears “cool” or bluish white.

The Preliminary Study

In the preliminary study that was conducted in a laboratory using adult volunteers, Suk and Choi examined the effects of different CCT lighting conditions on the adults’ levels of physiological alertness. They did this by taking an electrocardiogram (ECG), a type of measurement that is affected by the alerted state of a person. The study took place in a room that had an LED luminous ceiling. The researchers could control the CCTs of the lighting.

Results

It was found that the 6500 K lighting condition caused the highest level of physiological alertness, and that the 3500 K condition caused the volunteers to feel the most relaxed.

Main Study

In the main study, Choi and Suk studied two classrooms of fourth-grade students. The students were taking math tests. In one classroom, there were LED lights that could be tuned to a CCT of 3500 K (a “warm” or yellowish white light), 5000 K (a neutral light), and 6500 K (a “cool” or bluish white light akin to natural daylight). The other classroom was fitted with standard fluorescent lights — this classroom acted as the control.

Results

The students achieved the best math test scores when they worked under the 6500 K lighting condition. When they were exposed to 3500 K lighting, they performed best on recess activities.

“The preliminary study and the field experiment fully supported a positive effect of 6500 K lighting on academic performance and 3500 K lighting on encouraging recess activities,” said Choi.

The students were also interviewed by the researchers to see if they noticed any changes in the lighting and/or their academic success.

According to Suk, “We were surprised by the fact that besides observing the performance improvement during the mathematical test, the interview results with young children — who have almost no background knowledge on lighting — were also in line with our empirical results.” Based on this information, Suk stated “This shows that the effect of lighting was direct and intuitive and that anyone, regardless of age or level of knowledge, could experience and be aware.”

Conclusion and Suggestions

The researchers came to the conclusion that the 6500 K “cool” light may be used to support a student’s learning during intensive academic activities, the 5000 K neutral light is good for reading activities, and the 3500 K “warm” light can be used to create a relaxed atmosphere that may be used when a recess activity is taking place.

Lighting may thus prove to be a useful tool in the classroom. A teacher can better control the mood of the class and the learning environment if he or she has the ability to adjust the lights as they see appropriate. This may be a real possibility as the research team have created a mobile-app-based dynamic lighting system that allows one to choose the lighting conditions of “easy,” “standard,” and “intensive”.

Do You Want to Know the Secret to Living a Fulfilling Life?

Do You Want to Know the Secret to Living a Fulfilling Life?

Don’t we all want to live a full, happy and satisfied life? For some of us, it need not be a long life as long as it’s been a fulfilling life of achievements, happiness and no regrets. But, how many of us actually go on to experience that entirely? It sometimes sounds more like a pipe dream–a fantasy rather than reality.

And then you’ll also get comments from some, saying that this ‘fulfilling life’ is only possible if you’re so rich that you don’t have to care about working, paying the bills or providing for your family. While there is some truth to that, I’m happy to say that financial freedom isn’t the only answer to living a fulfilling life.

Living a Fulfilling Life is Within Reach

Anyone can pursue a life of fullness, and it all starts with the willingness to learn. How many years has it been since you last attended a class in school? If you’re well into your adult years as a working professional, chances are it’s been a while. Do you remember the times where you had to wake up for early morning lectures? Or the times where you were rushing through a paper or project? And, of course there were the endless exams that you had to cram for.

As a young college student, I remember looking forward to the time when I would finally be done with school! No more homework, no more grades to worry about, no more stress! The learning was finally done and I could enter the working world.

Not so much!

Now that I’ve finally entered the working world, there are moments where I do wish to be a student again; it seemed less stressful then!

There is simply so much out there that I still need to learn and experience. Yet I find myself pressed for time. With family commitments, my business and my own social life to juggle, I’ve had to keep on finding for new ways to learn and absorb new information efficiently. Over the years, I’ve found that by learning new skills and knowledge, I was able to find answers and solutions to my problems, which allowed me to achieve a greater sense of fulfillment.

Learning Never Ends

The truth is, learning never ends. Generally speaking, it is true that a formal education and the resulting qualifications are important in securing good jobs; jobs that allow you to excel, earn more and perhaps become more successful in our chosen career. But going to school is only one type of learning. All throughout your life, you’re learning in many ways. All these experiences shape and grow you into the person that you are today.

There are many opportunities to further your knowledge and develop the skills you need throughout life. Knowledge can be acquired and skill-sets can be developed anywhere. However, lifelong learning is about creating and maintaining a positive attitude to learning both for personal and professional development.

Many people overlook the fact that learning can take place anywhere and in many forms. Most would tend to think of learning as the years spent in a learning institute, which occurs mostly in their younger days. And once you go out into the working world, your ‘learning’ ends.

This is not how it has to be–in fact, lifelong learning is a gift that keeps on giving.

The Importance of Lifelong Learning

Why is it important to become a lifelong learner?

A lifelong learner is motivated to learn and develop because they want to; it is a deliberate and voluntary act. Lifelong learning can enhance our understanding of the world around us, provide us with more and better opportunities, and improve our quality of life.

You’ll Remain Relevant in the Workplace

With advancements in society today, the human life expectancy continues to increase, which means more people are also retiring at a later age. So no matter what stage of life you’re in, being a lifelong learner brings its own rewards. It means we can get more personal satisfaction from our lives and jobs as we understand more about who we are and what we do.

This can lead to better results and a more rewarding working day in turn. Whether it’s for advancing your career, a personal interest or wanting to pursue new dreams, learning automatically pushes you forward towards progress and enhances your wellbeing.

You’ll Increase Your Earning Potential

From a financial point of view, a more highly skilled and knowledgeable worker is an asset to any company. This also leads to faster promotion with associated salary increases.

Someone who can offer more expertise will be of more value not just to employers but also to customers. Expertise is also, often, a key quality of an effective leader.

And since you’ll constantly be accumulating knowledge, you’ll have an edge on those who don’t value lifelong learning and can’t bring as much to the table. Your extra knowledge will translate into transferable skills, which means you’ll always be primed to blow the competition out of the water.

Learning Gives You Options

Of course, one of the most rewarding reasons for continuous learning, is that it gives you options! Successfully changing career path in mid-life and spending time informally developing expertise is more common than ever, especially during rapidly changing market conditions.

Whatever your age, it’s never too late to start fresh in life. When you start educating yourself and exposing yourself to new knowledge and information, you widen your opportunities. This will allow you to do more than what you may currently be doing, or give you a way out if you’re not happy or fulfilled with where you’re at now.

Our economy is shifting increasingly towards short-term and part-time contracts with more flexible work-patterns. We have to adapt to changes going on in the work-world, make more of ourselves by stepping out of our comfort zones, and break the false ideas about our potential and how we believe life is going.

Gain More with Cornerstone Skills

You may be well into your career, but feel like somehow, something is still missing. Or maybe you’re not entirely happy with where you’re at in your career path and feel it’s time to reflect and perhaps do something new. Or you might be thinking of retiring soon, and thinking about next steps after retirement.

The learning never needs to stop!

Transformation and change is in your hands–you have the power to make big things happen, and we can help teach you the skills. Don’t let life pass you by! It’s time to pursue a fulfilling and happy life.
