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”.

2. Put Your Goals in Writing

When thoughts are banging around in our heads, they can easily slip away. Walk from one room to another and you forget what you were doing!

Make sure your goals are concrete and written down. This will help you stay accountable to yourself and is the first step in completing your goal. By writing it on a piece of paper, you must put in the thought of how you should word it, what exactly you want to accomplish, and will make you consider if it’s truly worth it.

3. Prune Your Relationships

Too often, relationships can be destructive. This is often looked at through the scope of romantic relationships, but also consider life-long friends, family, and acquaintances. Are the people you spend time with bringing you down? Are they helping you achieve your goals or hindering? It can be difficult, but pruning your relationships can be the quickest catalyst in turning your life around.

4. Make New Friends

Don’t underestimate how a new person or group of friends in your life can change your outlook. Be open to meeting new people, both at work and in your personal life.

5. Get Healthy

When you feel great, good things seem to come your way. Working out helps you feel better about yourself and can help change your outlook on life. Eating right can help you have the energy to do more. Getting healthy can improve your entire outlook on life and help turn your life around.

6. Start Saving

For many, financial struggle can weigh heavy and be the cause of many problems. Without a change of job or career, changing your financial situation will take time and effort. Start saving with each paycheck to help build toward your future. Even if it’s a small amount each check, consistency in saving can help you change your path in the future.

7. Start a Business

Working for others can be tough. You may be underemployed, under-utilized, and under-appreciated. Starting a business can help you take control of your financial future.

Understand that you don’t have to quit your current job to start a business. Find something you love and have skills at and do it in your free time. If you’re in creative services, freelance. If you’re great at carpentry, build tables to sell. If you are a talented painter or crafty, start an Etsy store.

You may find that your side passion business can turn into more. Or, if you have the opportunity and skills, take the plunge and go all in. Working for yourself is challenging, but a great opportunity to change your life.

Helping others can change your outlook and help turn your life around. Changing the way you think about the world can play a part. But helping others can also open up doors you never had available. Being a good person can help you get out of a funk and can be the catalyst for change.

9. Learn a New Skill

When you have more skills, additional opportunities will be presented. If you’re tired of your blue collar job, take classes to learn computer skills. If you’re struggling to move up in your company, find a skill that makes you more valuable. And if you want financial freedom, learn a skill that can help you change your life. Knowledge is power.

10. Stop Watching TV

Watching TV can keep you distracted and take up a lot of time. Cutting out the time you spend watching TV and replacing it with more productive activities can help you accomplish more and stay focused.

11. Listen to Inspirational Content

You can learn much about yourself from others. Find inspirational and educational content that matches your needs and give it a listen. You may find that the advice from others in similar situations can give you the boost you need to change your life.

12. Stop Complaining

Negative thoughts and talk can turn people against you and make your outlook grim. Stop complaining so much and make the best out of your situation.

13. Find or Rekindle Your Passion

Doing what you love can change your entire outlook on life. When you’re doing things you hate, you can be more stressed and make life much harder than it needs to be. Find things you’re passionate about and rekindle the love for what you enjoyed in the past. Doing what you love can turn your life around and make each day more rewarding.

14. Take a Vacation (or Staycation)

Sometimes, hitting the reset button is all it takes to improve your situation. Taking a vacation, or staycation, is a great way to get away from the stress of the daily grind and recharge your battery. A vacation can give you the perspective you need to change your life.

15. Re-evaluate Your Attitude

How you view the world will often reflect in how you treat yourself. Re-evaluate your attitude and ensure that you’re doing all you can to make the most out of every situation. A change in how you view your situation can often be the push that helps you change your life for the better.
