Your phone’s blue light won’t actually stop you sleeping, according to an expert – but your phone is still the problem


We all have days when we use our phones right before going to bed, even though we know we shouldn’t. Admit it. We know our phones keep us awake. Some people try to mitigate the negative effects on sleep with blue-light glasses, which claim to block out rhythm-affecting blue tones in screen light, but if you’re using a fitness tracker (and if you are, it’s probably one of the best sleep trackers or best fitness trackers from our lists) you’ve likely had at least one morning when you’ve woken up, checked your stats and seen exactly how little sleep you had the night before. 

It turns out, it’s not the blue-light effect from your phone that’s keeping you awake at night, according to sleep scientist Dr Sophie Bostock. I met Dr Bostock at an event to celebrate the launch of the OnePlus Watch 2 Nordic Blue in Helsinki, and she was able to answer a few burning questions about late-night phone use.
