But one thing the internet has not given us is better sleep. A prominent Australian researcher warned that the light generated by backlit smartphones and tablets can mess with our body clocks. Professor Shantha Rajaratnam of Monash University says that the effect is worst when it’s shining close to our faces, which is precisely how we hold our phones and tablets.
While I gather some of the research underpinning this conclusion is fresh, I’ve been hearing this theory about our bodies interpreting screens as daylight for years. And I haven’t yet been successful in acting on it, even though I often have difficulty getting to sleep.
