Neuroscientist Russell Foster says brushing your teeth in the dark can help promote sleep, according to The Telegraph.
The secret of a good night’s sleep could be as simple as brushing your teeth in the dark, an Oxford Neuroscientist has claimed.
Russell Foster, professor of circadian neuroscience, claims that the bright fluorescent light of bathrooms wakes the body up just when it should be switching off.
He believes that simply brushing teeth in the a dark room could allow sleep to take hold more quickly.
“Sleep is the single most important behaviour that we do. Across our lifespans 36 per cent of our life will be spent sleeping,” he said following a lecture on sleep at The Royal Society in London.
