Do you sit on your computer or other electronic device in the evening or at night while sitting in bed? This could be the cause of your sleeplessness. The blue light emitted by our computers and other electronic devices is the same as exposing ourselves to sunlight. "Light is one of the most important external factors that can affect sleep. It does so both directly, by making it difficult for people to fall asleep, and indirectly, by influencing the timing of our internal clock and thereby affecting our preferred time to sleep." Many studies have verified this information.

What can we do to combat this? There have been advances through software applications which will change the light emitted by our computers based on the time of day. "Light influences our internal clock through specialized "light sensitive" cells in the retina of our eyes. These cells, which occupy the same space as the rods and cones that make vision possible, tell the brain whether it is daytime or nighttime, and our sleep patterns are set accordingly. "
There are applications that track the daylight time schedules in your area and adjust the type of light emitted from your computer accordingly.
One such application is called f.lux. If you're interested in reading about it the website is justgetflux.com. If you want to read about how artificial light affects your sleep an article you can look up is "How artificial light is wrecking your sleep, and what to do about it" by Chris Kresser.

I have a hard time falling to sleep without some sort of noise, i.e. the TV or my cellphone. I found a good app for my phone that allows my brain to relax while reading my phone. I have installed the app, "Twilight", from Google Play on my phone and tablet. That has helped a lot when I'm laying there, thinking, and reading my phone in bed. The reddish light is calming and doesn't allow my brain to stay in a constant state of alert.

CPT (Join to see) Within 5 to 10 seconds of my head hitting the pillow I'm out for the night. I've never had a problem sleeping. I guess I'm lucky!

LCDR Rabbah Rona Matlow My wife hates me for it - not totally, but because I fall asleep so fast. I can roll over and she will say something and I'm asleep - can you image?

CPT (Join to see) Unfortunately you are correct. I believe the male species was born with that from birth. LOL!
