Do You Know that the Computer Can Disturb Your Sleeping Patterns?

For those who lack sleep due to computer overwork, here is an article for you. Take control of your sleeping patterns by getting rid of the blue light emanating from your computer. 

What does the blue light do to your brain and how does it affect your sleep? Listen to the video and appreciate how research findings can improve the quality of your sleep and affect your way of life in general.

Relationship between Hours of Computer Use and Sleep Time

I noticed that there seems to be a connection between the hours I spent sleeping and my use of the computer. As I stay logged in late in the night staring at the computer screen, the shorter my sleep time. I thought, “Is there a relationship between computer use especially at night and the number of hours I spent sleeping?

I’ve read somewhere that the computer does affect sleeping patterns. So, this could have been resolved simply by sleeping early thus avoiding the use of computer which may have been the culprit for my lack of sleep. But during times when I need to keep up with a heavy workload, I have to stay awake until late in the evening.

The Effect of Blue Light

Once again, I searched the internet for the specific effects of the computer to sleep. Then I came across a youtube video on how to sleep better. That video reminded me of the “blue light” emitted by the computer.

The video did not explain why blue light affects sleep but I remembered I read an article about it. According to research, blue light from the computer inhibits or reduces the production of melatonin, a sleep hormone. Thus, my lack of sleep may be due to reduced melatonin levels. I searched further in youtube about the blue light and what it does to melatonin. And I found a good explanation by Dr. Dani. I embed the helpful video below.

How to Counter the Effect of Blue Light

Knowing about blue light and upon hearing from another youtube video that it can be countered by wearing glasses with red filter or ultraviolet light protection, I resurrected my old sunglasses to experiment. I placed it on top of my progressive lens while typing in front of the computer late into the night.

At the first night I did it, I gained one hour of sleep and on the second day, I gained another hour. The latter gave me enough sleep, a full 7 hours, and greater energy to run early in the morning. I covered 7 kilometers that day in 39 minutes.

In summary, the lack of sleep that you may be experiencing may be attributed to the blue light emitted by the computer. Counter it by wearing glasses with red filter or sunglasses that serve the same purpose. If it doesn’t work then there may be other reasons.
