Blue Screens...



I’m sure you’re wondering what blue screen has got to do with being an author. Well, it has a lot, in my opinion.


How many hours a day are you on a laptop, phone, tablet, or even watching TV?

This is part of our job, but at the wrong times, this can really affect your productivity and even cause some health issues.


Blue Light explained.


First off, let’s take it back to basics.


There are four types of light, and they carry different wavelengths. The longer the wavelength, the fewer health effects there are.


Violet: Also known as UV light. - Highest.

Blue: - High

Green: - Lower

Red: - Lower


Our brains know that blue light means it’s daytime. In a sense, when you are looking at screens at night, it fools your body into keeping it awake, as it associates the blue light with daytime. So when we spend so much time in front of screens, especially before we go to bed, it interrupts our natural sleep pattern and affects the quality of sleep at night.

Every gadget uses a blue screen because they are cheaper to produce.

Do you get that feeling when you wake up; and just feel tired and keep hitting that snooze button? Well, tonight, try to switch off all devices at least one to two hours before bedtime and see how you sleep.

Blue light also suppresses and decreases our levels of melatonin. This is a hormone that is produced at night and helps your body sleep. So when it’s low, it reduces alertness and makes us feel tired.

Low melatonin has also been linked to depression, diabetes, and even cancer.


So what can we do…


Screen protectors that block 60% of Blue light.


You can buy eyewear that doesn’t block blue light. Instead, it absorbs the blue light and allows all other colors to go through.


Turning off all your devices one hour before bedtime and picking up a paperback or even meditation instead. Anything that gradually allows your brain to wind down. If you are playing video games before bed, you can imagine how much that stimulates your brain, and then you expect to jump into bed and sleep. That’s not happening. Our brains need that time to wind down or switch gears into a gentler mode.


Blue light can damage the retina and cause fatigue, dry-eyed, and even affect the memory, so doing small things now can really have an effect on your health in the long run.


Most Apple and Samsung Galaxy phones have a blue light mode built into them. It may be called nighttime mode on some. For me, on my Huawei phone, it’s called eye comfort mode and turns my screen yellow.

I hope this helps.

I’m also a little obsessed with fun facts, so here is one for today: The “M's” in M&Ms stand for “Mars” and “Murrie.”
