We could accomplish so much if we just cut out sleep from our daily schedule. Sounds ridiculous, doesn't it? But that?s essentially what folks are doing by using their electronic devices at night. Today we'll discuss not letting blue light affect your sleep.
Why do we need to sleep, anyways? As the saying goes, "I'll sleep when I'm dead." Not exactly a wise idea.
Sleep is a critical time when our bodies replenish and repair the wear and tear from our daily activities. This happens at a cellular level. Little bots who live in our organs get to work with little brooms, sweeping off our cells and put our building blocks back into place.
But what if you're doing things that cause your body to not fall asleep? How does blue light affect your sleep, and what changes can you make to level up your sleep game?
Almost every one of us depends on the convenience that our gadgets offer. It?s not entirely a bad thing, since smartphones, tablets, and computers definitely add to our quality of life. Our productivity goes up, making a lot of lives and tasks much easier.
However, is too much of a good thing a bad thing? To put it plainly, yes. In this case, too much of a good thing can have severe effects on those who unwittingly use this new technology without the proper habits or protection.
Light, before anything else, is a stimulus.
Natural light from the sun is very balanced in terms of composure. This means that it has just the right amount of blue light that the body can handle safely, since the human body has had hundreds of thousands of years to adapt to it.
Artificial light, on the other hand, refers to any sort of lighting that is man-made. The light given off by electronics tends to give off more blue light. The body reacts to this blue light similarly whether it comes from the sun or a cell phone.
Ultimately, blue light coming off our electronic devices can affect our body's balance and disrupt our circadian rhythm.
How does our body know when it is time sleep? It depends on our circadian rhythm, which is our body?s natural clock. It's how our bodies know how to wake up in the morning, when to eat, when to think about big problems, and when to sleep.
Our clocks are re-synced by the rising of the sun. Body clocks average 24-hour-cycles but can range from 22-26 hours. There are rhythms and oscillations that take place over the day.
The circadian rhythm is influenced by light sensitive retinal proteins that trigger signals to the suprachiasmatic nucleus, or SCN for short. The SCN is a group of cells that lives in the hypothalamus, just above your mouth?s hard pallet. It receives info from the retina, influenced by light, to promote sleep or wakefulness.
Based on the signals it receives, the SCN then sends a message to the pineal gland to release melatonin. What is melatonin? Melatonin, also called the sleep hormone, is mostly produced during nighttime. It's responsible for making us feel drowsy and also reducing our body's temperature at night.
While our bodies are constantly influenced by neurochemical changes of our ?chemical soup?, our eyes are extremely sensitive to light, and respond by increasing melatonin when there is less light to activate the SCN. This works in the reverse - when our eyes detect light, mainly in the morning, our body slows down the release of melatonin so we can wake up, bright eyed and bushy tailed, as we drag ourselves to the coffee maker.
If artificial blue light slows down the body's natural production of melatonin at night, do you see how that can affect your sleep quality and getting to sleep quickly?
According to research, excessive light can disrupt our normal sleep cycle. Many studies report blue light disrupts sleep. There is a plethora of science to back up these claims.
There?s no denying that proper sleep is one of the many keys to a balanced and healthy lifestyle. If one doesn?t have the ability to cut back on using electronic devices during resting hours, then it?s necessary to take additional precautionary measures.
Making a small investment and purchasing a blue light filter can yield incredible results. As of 2018, there?s no better way to counter the negative effects of blue light exposure than blue light filters.
Blue light filter glasses are a fantastic choice for a number of reasons. They are highly portable, relatively cheap, and have incredibly positive results on one?s health. Depending on the model you could even make fashion statement.
Blue light filter panels are also an excellent alternative. Putting one on the TV can be the difference between a cozy nap on the couch while watching Doctor Who reruns and visiting the doctor for prescription glasses. So please, take these small, efficient steps and improve your quality of life.
If you're a heavy computer user for work or play, your best bet is to get a low blue light monitor that has special blue light reducing features, or a flicker-free screen to decrease eye strain.
Whatever option you choose, take care of your body and limit the amount of blue light you receive. By following this advise you'll sleep better and no doubt Level Up Your Sleep Game.
Simply put, blue light is just a color that can be seen by us because it is part of our ?visible light spectrum.? Blue light is something that is all around us all of the time and it is both beneficial and problematic for us for a few different reasons.
Today we are going to be looking at the science behind blue light, where blue light can be found and the problems that it can cause.
One of the most important things to remember about light is that it can be broken down into electromagnetic particles that all travel in waves. The waves themselves have different wavelengths that can be either short or long, and they are all capable of emitting different amounts of energy.
Generally speaking, wavelengths that are shorter have a higher amount of energy and wavelengths that are longer have less energy.
When we look at different wavelengths and try to turn them into diagrams, they are usually all represented by different colors. On a scale you would find colors like red and orange at the right hand side and colors like blue and violet at the left hand side. The left-hand side also ventures into the non-visible color spectrum, which includes wavelengths that our own eyes cannot see at all.
This ?diagram? is considered by most to be our electromagnetic spectrum. The electromagnetic spectrum includes a number of different categories, ranging from x-rays, gamma rays and UV rays to visible light, infrared waves and radio waves.
So, where does blue light come into this? When we break all of the colors down in the spectrum we can see violet, indigo, blue, green, yellow, orange and red, in that order. Blue is close to the non-visible side of the scale and it has an incredibly short wavelength.
As you already know, a short wavelength means that blue light emits a lot of energy. Over the past few decades, a lot of different studies have proven that blue light does long-term damage to our eyes and can affect our health in a number of other ways.
Blue light is not a supernatural foe that we should avoid at all costs. It is something that surrounds us on a daily basis. Have you ever wondered why the sky looks blue? It looks blue because of the blue light wavelengths hitting molecules of air in our atmosphere, causing blue light to scatter across them. The sun and our own atmosphere cause this to happen and create skies that we associate with beautiful, sunny days.
The fact that this natural form of blue light exists is actually really beneficial for us as humans. It has led to us using blue light to regulate our own circadian rhythm, or our natural cycles of both being asleep and being awake. Blue light is even known to make us feel more awake. It can also make us happier and speed up our own reaction times.
How could this natural blue light possibly be a bad thing? In reality, the natural blue light that we are exposed to is not the problem. The unnatural blue light that we are exposed to is.
Unnatural blue light comes from a variety of different sources, including digital screens like televisions, computers, laptops, smart phones and tablets. It is also emitted by both florescent and LED lights.
The problem with blue light can be seen when we look at it as short wavelengths with incredibly high amount of energy behind them.
The high energy actually makes them flicker a lot more than other wavelengths on the electromagnetic scale. This flickering creates a type of wave that affects both the sharpness and clarity of what you are looking at if you are looking at a screen that emits blue light.
Unfortunately, this is something that can cause an array of problems including eyestrain, headaches, migraines and physical fatigue. It can also cause mental fatigue and affect your mental wellbeing. As we are sure you can imagine, this is something that could affect your actual ability to work and your overall productivity if you are at work.
Our eyes are not able to filter blue light out on their own, nor will they evolve to do this over thousands of years. We rely on blue light to keep our circadian rhythm in time and to keep our bodies healthy, but prolonged exposure to blue light can also damage the retinas in our eyes and cause premature degeneration of the eyes themselves.
Luckily, with every problem that appears a solution shortly follows. The main problem with blue light and our eyesight is that fact that we constantly expose our eyes to electronic screens.
By using a filter, you can stop your devices from emitting as much blue light as they usually do, and by wearing blue light filter glasses you can make sure that your eyes are protected in more ways than one. If you are a heavy computer user, consider getting a low blue light monitor for your home or work to help decrease eye strain.
Blue light is something that surrounds us every single day. It is the thing that makes our sky look blue and because of that, it does some wonderful things for our bodies. But, it is also emitted from a range of different electronic devices and that can cause it to create havoc and mayhem inside of our bodies.
Blue light is part of our electromagnetic spectrum. It can be seen as part of our ?visible light? area, but it is only a few steps away from our ?non-visible light? area.
This makes it quite dangerous because it means that it has short wavelengths and short wavelengths have a lot of energy, whereas, red light has long wavelengths and does not have much energy behind it because it is at the opposite end of the spectrum.
One of the best things about blue light is that it is directly responsible for our circadian rhythm. Our own exposure to blue light can affect our circadian rhythm a lot, but when that blue light comes from our own sun it makes sure that our sleep and wake cycles are both functioning naturally. This ensures that we are not losing out on sleep that we should be getting? unless we have to get up for work with an alarm clock of course.
Blue light is also known to make us feel much more alert and it can affect our reaction times. It can also help to elevate our mood whenever we are feeling down about something. This also explains why people get the winter blues when there are fewer blue skies and more dark nights around.
Blue light might sound wonderful. It can keep our bodies balanced and our minds healthy. It ensures that we sleep when we are supposed to sleep and that we wake up when we are supposed to wake up. It keeps us energized and gives us the ability to react quickly to a range of different situations.
But, blue light is also dangerous and has a negative effect on our bodies. This is because a lot of artificial blue light is emitted from our computer monitors, phones, and other devices that we use on a daily basis.
Blue light is emitted by televisions, monitors, computers, laptops, tablets, mobile phones and certain types of lighting. How often do you use your mobile phone every day? Most people use theirs a lot, and every single time they do they are affecting their body.
Artificial blue light can negatively affect your circadian rhythm because it lowers the production of melatonin inside of the brain. Melatonin is the hormone that lets your body know that it is time to sleep.
When less of it is produced, you will be less likely to sleep. In a natural situation, your body would start to make more melatonin as soon as the sun sets, but the blue light that is being emitted by electronic devices means that most people don?t start producing enough melatonin early enough.
Our bodies cannot filter in modern technology and work out new ways to behave so we have to help them. For example, by limiting your exposure to electronic devices at night you could help yourself get a better sleep. Researchers have also proven that prolonged exposure to blue light can cause symptoms like eyestrain and eye fatigue.
These are both important things to consider because we rely on technology in the modern world. A lot of people spend their working hours in front of a computer and their personal hours watching television or playing computer games. All of these activities can cause eye strain and eye strain can cause people to become unproductive and unhappy.
One of the things that researchers noticed about this is that a lot of people will simply ?put up with? strained eyes. They might notice that their eyes are uncomfortable, but they probably will not do anything productive about it.
They might have to use a screen frequently, or using a screen could be how they get enjoyment. Naturally, if your eyes are being affected in this way you should do something before your workflow is negatively affected.
Your vision could also start to become blurry due to the exposure to blue light. Blurry vision can make it hard to see what is going on on your screen and that can make it difficult to do anything. Blurred vision can also cause migraines that could make you feel like you need to sit in a dark room.
The problem with blue light and how it negatively impacts our bodies is that most people will simply ignore it and wait for it to go away. Unfortunately, the lasting impact of blue light exposure can be seen in a lot of different studies, where things like degenerative eye problems are quite common.
You should take the steps that you need to take to protect your eyes. Use a filter to stop the blue light that is emitted from your screen from ever reaching your face, or use a pair of blue light filter glasses to stop a lot of blue light from reaching you. Remember that not all blue light is bad, but some blue light is more than enough.
We are all aware of just how dangerous unnatural sources of blue light can be. Blue light reaches a part of our eyes that is so deep that it can damage the retinas inside of the eyes over time. It can also cause a lot of eye strain and mental fatigue, both of which impact your overall ability to work and have fun. Luckily, blue light filters claim to be able to solve all of these problems. But, what are they?
Blue light exists as part of our electromagnetic spectrum. Each of the colors in the spectrum has a different wavelength and each wavelength emits a different amount of energy.
Blue light has a relatively short wavelength and short wavelengths are known to emit a lot of energy, whereas rays at the opposite end of the spectrum (the red side) have longer wavelengths and emit less energy.
You might be wondering what you can do to avoid blue light altogether, but that isn?t really an option. Sunlight contains blue light and blue light is actually the thing that makes our sky look blue. But, there are also a lot of unnatural forms of blue light. These include fluorescent lights, flat-screen televisions, computer screens, smartphones, and a number of other electronic devices.
One of the main problems that we experience due to blue light is a form of digital eyestrain. This occurs because blue light scatters a lot and makes it hard for our eyes to focus on the source. Scientists have also found that most people simply ignore digital eyestrain, brushing it off as ?just one of those things? and carrying on with whatever it is that they were doing.
One of the most worrying things about blue light is that it also affects our circadian rhythm, our sleep and wake cycle.
If the only blue light that we were exposed to was from the sun, then that would be fine. But, we are exposed to a lot of blue light from unnatural sources after the sun has gone down. This stops our brains from producing as much melatonin, the sleep hormone, as they otherwise would, and makes it much more difficult for us to sleep.
Regardless of all of this, blue light is also beneficial for us. A lot of research has been done into the topic and it has found that blue light makes us much more alert, helps us to remember new information and increases our reaction times.
Blue light is also used frequently to treat SAD, the seasonal affective disorder where people experience low moods when they are exposed to less sunlight.
When it comes to blue light filters, there are two different options that most people are willing to consider. They come in the form of screen protectors that cover the source of the blue light and glasses that cover your eyes to reduce their exposure to blue light.
Everyone would benefit from using at least one of those filters to protect their eyes. For example, if you work in an office building and use a computer for most of the day, then you would benefit from using a screen protector that you can simply place over the screen of your computer. This will help reduce the amount of blue light that can reach your eyes.
Blue light filters like this can be used on your phone, tablet, computer screen and even your television in order to prevent a large proportion of the blue light that is being emitted from them from ever reaching your eyes. It is worth noting that a lot of different blue light filters are made out of tempered glass, meaning that they can also protect the devices that they are covering.
Blue light-blocking computer glasses are special-purpose glasses that you can get without the need to see an optician. These glasses can also be worn if you routinely wear something like contact lenses.
A lot of different blue light blocking glasses are also capable of reducing glare and making sure that things do not reflect off of them, protecting you from both natural sunlight and blue light.
It is worth noting that you can also purchase things like anti-blue lightbulbs to protect yourself inside of your home. This is especially useful if you find yourself turning your lights on a lot at night.
Try to remember that, while not all exposure to blue light is bad, constant exposure to unnatural sources of blue light can be incredibly detrimental to both our physical and mental health.
Blue light filters should be used as a precautionary measure to protect your eyes, especially in the digital era that we all live in. Unfortunately, we cannot afford to go wrong with our eyes and unnatural exposure to blue light is not worth the risks that come with it.
