Insomnia-curing video goes 'viral'

ZZZZZ: A video of a river has been a huge hit with those looking for a good night's sleep.

Film of an Irish stream shot by visual artist Johnnie Lawson has been viewed over 6 million times and its effects are so impressive that it's being incorporated into medical research. 

The video, of the River Bonet flowing under a bridge and over rooks in dappled sunlight, shaded by trees, isn't what typically ends up getting thousands of shares across the social web.
