Blue Light From Our Tech || A Path To Poor Sleep

23722469_903171486507420_4400315278131753784_nDid You Know? The blue light emitted from most electronic screens will effect your sleep quality?

With our reliance on Smartphones, TVs, Desktops Laptops etc. at an all time high, it’s easy to lose sight of what’s important.


Or more importantly – good quality sleep.

How often do you use your device before going to sleep?

It may be time to reconsider.

Research indicates that the blue light emitted from our devices will reduce production of Melatonin – an important hormone for sleep and wake cycle regulation.

We produce melatonin as night falls to prepare our body for sleep. As light starts to filter through again in the morning Melatonin production reduces and our sleep cycles end.

Staring at a screen before going to sleep effectively stuffs our Melatonin production into a sack an beats it with a stick. You might still sleep your usual hours but the quality sucks.

It’s an important idea to be aware of.

Shawn Stevenson, author of the book “Sleep Smarter” and host of The Model Health Show has this to say.

“They found that for each hour of exposure to blue light, melatonin would be suppressed for approximately 30 minutes…

Going to bed without normal melatonin production results in devastatingly poor sleep cycles, and not being able to fully rejuvenate your brain and body. But that’s just scratching the surface…

Suppressed melatonin disrupts the normal function of virtually ALL other hormones in your body. Hormones related to weight management, digestive function, and immune system function…

Interfering with your body’s production of melatonin increases the risk of cancer, obesity, gut dysbiosis, diabetes, and more. This integral hormone matters a lot, and something clearly needs to change.”

So what to do?

The obvious one is to try and ween yourself off the tech immediately before going to bed or at least once you’re in bed.

Secondly it’s intetesting to note that there are a number of blue light blocking apps that filter out the suppressive blue light.

Most Android (drop down feature) and Apple (Night Shift) phones now have a feature to assist this.

For laptop and desktop devices Shawn recommends the use of the app f.lux. As the sun goes down, the app will start to remove the blue light from your screen.

There are a number of Android apps that do the same thing.

I’m personally using the Twighlight app.

Most are pretty simple and have a PAUSE function for times where accurate colours are important for work etc. Quite nifty.

This is just another example of how the modern world may leave a subtle, yet potentially nasty legacy on our health and well-being.
