Blue Light

The two major hindrances to my personal recovery process are the recurring fluid around my lungs and really bad insomnia.  According my son Chris, one of the contributing factors to my not being able to sleep could be Blue Light. But what is it and where does it come from?

According to WebMD,

Blue light is needed for good health: It boosts alertness, helps memory and cognitive function and elevates mood. It regulates circadian rhythm – the body’s natural wake and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm.

How Blue Light Hurts Sleep

Your eyes aren’t good at blocking blue light. So almost all of it passes straight through to the back of your retina, which helps your brain translate light into images.

Exposure to all colors of light helps control your natural sleep-and-wake cycle, or circadian rhythm. More so than any other color, blue light messes with your body’s ability to prepare for sleep because it blocks a hormone called melatonin that makes you sleepy.

Bottom line: You’re less drowsy than usual at night, and it takes you longer to fall asleep.

Blue Light Sources

Americans spend an average of 7 hours a day on electronic devices. That’s a lot of time staring at blue light. Worse yet, nine out of 10 Americans admit to reaching for an electronic device at least several nights each week shortly before bedtime. That could be an invitation for insomnia.

The light from your devices often appears white. But they can give off wavelengths in the range of 400 to 490 nanometers, which is blue light.

Indoor sources of blue light include:

  • Televisions
  • Smartphones
  • Tablets
  • Gaming systems
  • Fluorescent light bulbs
  • LED (light-emitting diode) bulbs
  • Computer monitors

Solutions

The obvious answer is: don’t watch TV or work on your phone/iPad/PC before you go to bed.  But short of that are blue light blocking glasses (made to your reading strength, which you need to know).

I just bought a pair from amazon ($18) and will see if they help at all.

You have any experience with the blue light issue or solutions?

Lung Fluid??

On the issue of fluid buildup in my lung sac.  On Monday, I had a cat scan to look for fluid and on Tuesday met with my heart surgeon to get the results.

The right side is still clear and OK (a good sign that my body is adapting); but the left side has “some fluid”… but according to the Doc, as long as I was breathing OK, nothing they will do anything about.

Now it is time to turn my rehab attention to eating MORE to put some of this lost weight back on my now boney frame + improve my red blood cell count.  Today DeDe and I are off to McDonald’s for chicken McNuggets and a chocolate milkshake!

  1. You probably know this, but most smartphones have a “comfort” setting for the display that takes out the blue light. Very helpful.

    Dan, i did not know! thanks, george

  2. For your insomnia, maybe you could find a video on the web of a 5 set clay court match between two moonballers (maybe Solomon vs Dibbs?).

    Jack, that would do it! thanks, george

  3. George,

    Thanks for the info on blue light. I have made it a practice for many years to turn off all devices 1 hour before my schedule bedtime. I like to read just prior to bed time and it makes me go to sleep. Even then I use a small reading lamp attached to my book so I do get much transmitted light.

    Glad to hear some of your fluid is not returning and hopefully the other will absolve. As for weight gain – I make an “everything” smoothie. It contains 2 cups of almond beverage, 1.5 cups oatmeal, 2 cups spinach or kale, 1 whole apple, 1 whole orange, 3 oz yogurt, 1 tbs almond butter (protein & flavor), 1 tbs frozen yogurt (more flavor), and 1 cup of ice cubes. You could also add some powder protein but I like to stay all natural. This makes about 4 x 16 oz smoothies. Or go to Smoothie King and make them do the work! Good luck and continue to keep getting better. Starr

  4. Having had my share of sleep issues, and going to sleep Doc, all the above are correct. No computer or phone before bed, and all off. Take a book or reading material…….no Playboy…………..and relax. And, a dark, cool room, no led lights shining from extension cords, TV etc.

  5. Hi George – I had bouts of insomnia as a young guy . The book – The Relaxation Response – by Herbert Benton was a very helpful tool. Also if you have a TV in your room – YOUTUBE has DARK SCREEN relaxation / meditation music channels that run anywhere from 3 to 12 hours at a clip – be sure your doc knows about it . A solid 30% of bypass patients develop some sort of post op anxiety issues . Your doc will be well aware of that and may be able to guide you to helpful action

    Howie, tks. I have an Alexa in my bedroom and use everything from soft music to the sounds of rain! george
