We’ve been warned about the dangers of scrolling through social media right when we wake up and right before bedtime. That bright blue light that comes from your phone screen disrupts your sleep patterns but new research shows it can bother your body in other ways, too.
A new study from Northwestern University looked at how being exposed to that bright light affects our metabolism and if the time of day we get it makes a difference. They had some people spend three hours on their smartphones or computers right after waking up and some did their time before they turned in for the night.
Turns out, in both groups the bright light messed with their metabolic function by increasing insulin resistance – that raises the risk for getting type 2 diabetes. NOT good! And the screen time before bed was especially bad because it led to higher blood sugar levels than the morning exposure. And that extra glucose can lead to excess body fat over time, so it’s totally not worth those ten minutes on Twitter.
So what can you do to stop the bright light waves from making your waistline bigger? A digital detox could be the answer. Try not powering on until you get to work in the morning and definitely go screen-free for the last hour you’re awake before bed. If that sounds nearly impossible to you, at least lower the brightness on your device. Your metabolism will thank you.
