Is your smartphone keeping you up at night?

Researchers at the Lighting Research Centre have recently found that two or more hours of exposure to backlit devices suppresses melatonin, a natural sleep-inducing hormone that is found in your body.

So whilst you may be cosy and relaxed in bed trying to relieve your stress with a few late night emails, texts or catching up on some television, you may be raising health issues that affect your lack of sleep. According to the National Institutes of Heal (NIH), sleep deprivation can wipe out almost all benefits of a healthy diet and regular exercise regimen (Natural News).

The light that is emitted by electronic devices like tablet screens, television screens and smartphone screens is “blue” light which keeps you awake. When there is a higher level of blue light being emitted, the longer it takes for you to fall asleep.

The Guardian asked respondents whether they used these devices in the two hours before going to bed. Nearly 80% of respondents routinely use these devices during this period. When looking at 18 to 24 year olds, this figure increases to a 91%.

So next time you consider checking Facebook before trying to nod off, maybe think again!
