(CNN)The clocks went back one hour across Europe at 2am on Sunday October 25, giving everyone across the continent an extra hour in bed, and signaling the start of winter.
In the UK the clock change signals the end of British Summer Time and the beginning of Daylight Saving Time, which will last until the last Sunday in March.

"We know that green space and blue space are very soothing, so anywhere where the environment looks pretty is actually beneficial -- so having a walk down to a local riverside, or if you can get to a beach," she says.
Even if you live in a city or an urban environment, getting out and looking at your surroundings can still really help -- especially if you go out with a "purpose" -- for example looking at different bird species, or plant varieties.
"You can find nature in anything," she adds.
And if you find you need a mood boost when back indoors, a SAD
