Wearing sunglasses at night can actually help you sleep, researcher claims

Rock stars have long sworn by it - but it turns out there’s a pretty good reason you might want to wear sunglasses at night (beyond looking cool).

Wearing sunglasses in the two hours before bed can actually help you sleep, a researcher has claimed.

The reason is that we’re constantly overloaded with artificial light, which overloads our body clock - and sunglasses are a way to ‘turn it all down’, according to Glenn Landry of the University of British Columbia.

Landry says, ‘Beginning at eight at night, two hours before I want to go to bed, I wear sunglasses. Not because my future’s so bright, but because I’m trying to avoid light. I’m trying to tell my clock that this is the end of the day.

‘We have artificial sources of light available to us 24 hours a day. We’ve got our laptops with us, and we’re doing email and we’re watching TV late at night. And so we’re getting light at night and this impacts our circadian rhythms, our daily biological rhythms.’
