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”.

10 Simple Strategies to Make Your Life Better Starting Today

10 Simple Strategies to Make Your Life Better Starting Today

Habits are an important part of the direction you take your life, and — as I’ll share with you shortly — there are certain daily habits you can adopt right away that are guaranteed to improve your life.

Think back to when you were just six or seven years old…

At that age you probably didn’t have many habits. But, as the years went by, you picked up more and more good and bad habits.

You may not have thought about it before, but habit forming never really stops.

That’s why it’s never too late to change your habits and transform your life.

So, if you feel burdened by your bad habits, start kicking them into shape by replacing them with these 10 positive, life-changing strategies:

1. Go to Bed a Little Earlier and Wake up Earlier 

Starting tonight, get yourself to bed 30 minutes earlier than usual. And, then make sure you get up tomorrow morning 30 minutes earlier, too. This small change can have a BIG impact on your day.

Instead of furiously rushing in the morning to get ready for work, the extra time will give you a golden opportunity to start your day off on the right note. You can drink a smoothie while sitting on your porch, spend 10 minutes exercising and stretching, and still have time to read a few pages of an inspiring book.

2. Be Grateful for the Good Things in Your Life 

Setbacks and obstacles are inevitable in life. But, with a positive mindset, you’ll be able to overcome most of these. And, when you do, you’ll boost your self-confidence. 

This is something you can definitely be grateful for. 

However, if worst-case scenarios are playing out in your life, then sometimes, to stay strong, you’ll need to keep your mind on the good things that are happening to you. For example, your relationship with your partner might be crumbling, but your career is continuously getting stronger. It’d be easy to feel downtrodden and miserable about your relationship problems —  but, it would be much healthier to keep your mind and gratitude on these things that are going well, such as your career.

3. Drink Water All Day Every Day 

I’m sure you’ve heard the advice of drinking at least eight glasses of water a day, but are you following that advice? If not, you’re robbing your body and mind of essential hydration. 

With the right amount of water intake a day, you’ll be amazed how good you feel — and how good you look!

4. Take 15 Minutes to Set Goals for the Day, and Then Tackle Them One by One 

This strategy will put your life into a new stratosphere! And, it’s very simple to do.

Simply spend 15 minutes in the morning (either at home or at work) planning what you need and want to achieve during the rest of the day. Once you’ve listed your tasks, the next step is to put them into order of priority. 

For instance, you have three things to do: catch up with your emails, write a project update, and prepare a briefing for your CEO. It’s best if you put these in order of importance. In this example, your emails can probably wait until you’ve created your CEO brief and updated your project documentation.

5. Turn Off Your Cell Phone (or Put it on Airplane Mode) When You’re Focusing 

A 2012 study found that even looking at a cell phone or feeling it vibrate in your pocket can significantly distract focus and reduce your ability to complete complex tasks.[1]

It’s no surprise really, as our thoughts are subconsciously drawn towards checking our phones when they’re switched on. It’s a bad habit — but one that most of us have. However, when you need 100% focus (like I do when writing my articles), then switching your phone off, or at least putting it into airplane mode, will free your mind and supercharge your focus. Try it and see!

6. Walk as Much as You Can 

Have you noticed that most people’s lives are sedentary? They drive to work, sit in front of a screen all day, then drive home and binge on the latest Netflix series. It’s no wonder there’s a growing epidemic of obesity and mental health issues. 

Our bodies are made to move — so we should move them! This can be as simple as walking up the stairs to your office instead of taking the elevator, and going out for a walk around the block at lunchtime. In the evening, instead of arriving home and crashing on the sofa; spend 20 to 30 minutes walking around your block.

When you make these things a habit, you’ll be amazed by how much better you feel. You’ll have less stress — and more energy.

7. Be Mindful of Your Surroundings

How often do you stop, think and appreciate the “here and now”? I’m guessing not very often. But, I understand why. Modern life is demanding and fast-paced. There’s precious little time to appreciate the small things. 

But, if you want to live a healthy and happy life, you must break out of this trap. You can do this by allocating 15 to 30 minutes each day for mindful meditation. This could be in a park, in your garden, or even in your lounge. The trick is to focus 100% on your surroundings. 

For example, if you’re outside, watch how the leaves on the trees blow around in the wind. By keeping your focus on this movement, you’ll clear your mind from your usual stresses and strains. This will give you brain a much-needed break. And, as well as improving your mental health; you’ll find your creativity gets a boost, too.

8. Ask for Help When You Need It 

No one can know or do everything. Which is why you shouldn’t be embarrassed to delegate tasks to others when needed, ask questions when you don’t have the answers, and work with partners and colleagues to clarify intentions. 

When I first set up Lifehack, I tried to do everything myself: blog writing, website creation, marketing, financial planning, etc. However, I quickly learned that it was much better to hire some help. Not only did this inject some fresh ideas and inspiration into Lifehack — it also made the whole operation way more enjoyable!

9. Practice Self Care 

Are you looking after yourself as well as you should? If not, then take steps to improve your diet, exercise more, and to speak to yourself with encouraging words and thoughts. 

The latter suggestion is often overlooked. But how you speak to yourself determines how you feel, what you believe, and what you achieve.

10. Embrace Learning 

You cannot transform your life without learning something new. That’s because the process of change forces you to adapt. But, many people stop learning as they get older, as they find the learning process boring and bothersome. However, it doesn’t have to be this way. It can be fun and rewarding. 

Whether you decide to learn to play guitar or study the basics of accounting — embrace learning, and begin changing your world for the better.

I’m sure you’ll agree that these 10 strategies are simple enough for you to start putting them into action in your life. (I suggest you begin today!) 

Nevertheless, you’ll probably need to use some extra willpower for the first 30 days or so, as this is the typical length of time it takes to create a new habit. After that, these strategies will be part of your day-to-day life, and you won’t need to think about having to do them. In other words, they’ll have become habitual actions.

If you need any further encouragement to get started with the 10 strategies, then consider this:

Even just adopting one of the strategies can turn the tide in your favor. But, when you implement all 10, you’ll create an unstoppable trend towards success, health and happiness.

So start making your life better — today!
