What impact are our electronic devices having on our sleep quality?

Is the BLUE light emitted from devices affecting SLEEP?

For us to sleep we need our mind and our body to be relaxed. If we are using phones and electronic devices late at night, then the blue light that is emitted can have a negative effect on your sleep. The blue light tricks the brain into thinking it is daytime and reduce your body’s ability to produce melatonin, the hormone that helps you sleep. It takes two hours for the melatonin levels to reach the point that sleep becomes easy.

So Frank goes through how to help by switching your devices to ‘night time’ mode and remove the blue light that is normally emitted.
