Understanding the Link Between Blue Light & Sleep Quality

Understanding the Link Between Blue Light & Sleep Quality
When your head hits the pillow at night, the goal is always the same: get good sleep. Whether you've had a long day or a great day, turning in for the night is always a welcome task.

Boosting your energy levels, resting and relaxing, and taking care of your health are all possible with sleep, so it's only natural to want it every night. However, if you're like most people, sleep doesn't come easily.

Research suggests that 50 to 70 million Americans have sleep-related problems, and these issues are not limited to a specific age, gender, or socioeconomic class. Additionally, in America, 70 percent of adults say they get insufficient sleep at least once per month, while 11 percent report getting insufficient sleep every single night.

Evidently, sleep health is a massive problem in the United States, and there are various reasons for it. If you regularly toss and turn at night, you could have a medical or sleep disorder. Or you could be suffering from the one thing that's often overlooked but just as damaging: blue light.

Studies suggest there's a link between blue light and sleep quality. And specifically, these reports indicate that blue light negatively affects how well you sleep.

What is blue light?

Before examining the link between blue light and sleep quality, you need to have a good understanding of blue light. In simple terms, blue light is one of many colors in the visible light spectrum. The other colors are orange, yellow, red, violet, blue, green, and indigo.

These colors work together to make white light, which you see whenever the sun shines. And surprisingly, the sun is also the primary source of blue light, making it impossible to avoid.

Other sources include digital screens like TVs, computer monitors, tablets, smartphones, gaming systems, and laptops. So whenever you're scrolling through social media, online shopping, or simply working or answering emails for your job, you're exposing yourself to blue light.

But unlike the sun, digital screens are things your eyes are constantly glued to and focused on. From the time you wake up, you're usually looking at digital screens.

Most people's day starts by checking their phone and responding to texts. Then, they go to work and stare at a laptop. If they rely on public transport, they stay on their phone during the train or bus ride home. And before they go to sleep, they unwind by watching TV.

Digital screens play a significant part in everyday life, and if you're looking at them almost 24/7, your exposure to blue light is higher than it should be. Even worse, your exposure is happening at times that it shouldn't, which isn't great for your sleep quality.

Studies on blue light and sleep quality

When you stare at digital screens at night, you're impacting your circadian rhythms. These rhythms are 24-hour cycles that tell your body when to conduct certain functions.

Light is the primary factor that aligns your circadian rhythms, and throughout history, the sunrise and sunset have been the most prominent elements affecting them. However, the dawn of artificial light from electronics has dramatically increased the amount of light that you're exposed to before bed. And while various types of visible light can influence your circadian rhythms, blue light is the only one with the most significant effect.

In some ways, this is great. The blue light exposure that you get from the sun can increase alertness and jumpstart parts of your brain. It can also improve attention and performance during the day. But at nighttime, the effects of blue light aren't as beneficial.

This type of light suppresses the release of melatonin, a hormone in your body that promotes drowsiness. Harvard researchers and their colleagues recently did an experiment to compare the impact of 6.5 hours of blue light exposure to green light exposure of similar brightness. In the end, they discovered that blue light suppresses melatonin twice as long as green light, and it also shifts circadian rhythms by twice as much.

This insight matters because, without the release of melatonin, your mind and body won't think it's time to go to sleep. In fact, blue light exposure in the evening does a great job at tricking your brain to believe it's still daytime. And this trick disrupts your circadian rhythms, resulting in tiredness and the inability to stay alert.

Even worse, if your circadian rhythms are constantly misaligned, it can negatively affect your health. For example, you could experience depression or metabolic disorders from frequent shifts.

How to prevent the effects of blue light

With such a strong correlation between blue light and sleep quality, it's imperative to take steps to minimize your exposure to blue light. But that's not easy to do when you're always surrounded by digital devices.

You can't just ignore every single text message you get in the evening. You also can't avoid answering emails if something urgent pops up. And if you like to unwind by watching TV or scrolling through social media, you shouldn't have to flip your evening routine upside down. So, what's the best solution?

Well, if you want a remedy that's easy to implement but doesn't contain the power to disrupt your evening, you need to try blue light glasses. This solution is not only practical but also effective.

Blue light glasses have a filter that blocks out blue light and the range of wavelengths that digital devices emit. As a result, you can look at a digital screen at night without affecting your sleep quality.

With lenses that combat blue light, your body won't suppress melatonin, and your circadian rhythms won't experience disruptions. You'll finally be able to get the sleep you need without changing anything in your nighttime routine except the glasses you wear before bed.

However, it's important to note that you can't just wear any type of blue light glasses. The market is currently flooded with these products, but honestly, not all of them are created equal.

Some are very cheap but also ineffective. Others are effective but difficult to afford. And some blue light glasses just don't look good even though they provide results at a reasonable price.
