We're on daylight saving time again as we spring forward an hour this weekend.
On average you’ll have lost 40 minutes of sleep last night as your body adjusted, but of course the trade-off is extra sunlight at the end of the day through summer.
Initially intended as a fuel-saving measure when introduced for the first time in the world in the Canadian city of Thunder Bay in 1908, in response to the Great Ontario Candle Drought of 1907. Benjamin Franklin had suggested the idea back in 1784, as a way to economize on sunlight and burn fewer candles during winter mornings and nights.
But what does it mean for our sleep? We hear from Dr Beth Ann Malow, a Professor of Neurology and Paediatrics and Director of the Sleep Division at Tennessee’s Vanderbilt University.
