Denmark is often said to be the happiest country in the world. That's down to one thing: hygge.'Hygge has been translated as everything from the art of creating intimacy to cosiness of the soul to taking pleasure from the presence of soothing things. My personal favourite is cocoa by candlelight...'You know hygge when you feel it. It is when you are cuddled up on a sofa with a loved one, or sharing comfort food with your closest friends. It is those crisp blue mornings when the light through your window is just right.
