E-readers 'damage sleep and health,' doctors warn
If you curl up under the duvet with an ebook for a bedtime read then you are damaging your sleep and maybe your health, US doctors have warned.
A team from Harvard Medical School compared reading paper books and light-emitting e-readers before sleep.
They found it took longer to nod off with an e-reader, which led to poorer quality sleep and being more tired the next morning.
Experts said people should minimise light-exposure in the evening.
Whether you are perusing the Man Booker shortlist or leafing through Zoella, the impact of reading on your sleep is probably the last thing on your mind.
But there has been growing concern about the dangers of light before bedtime.
