Staring at your phone before bed DOESN'T make it harder to fall asleep, claims new study that contradicts official health advice

We're often told by health experts not to look at our phone just before bedtime as it affects our sleep. But according to a new study, there may not be much scientific basis to this at all. Experts say there's no decent evidence that exposing our eyes to'blue light' from a screen makes it harder to fall asleep. This contradicts official advice from health experts including the NHS, which tells people to avoid using phones an hour before bedtime due to blue light. Instead, the researchers think smartphones are interfering with sleep simply because we can't put them down at night.
