Long before you craved the perfect night in, the Danish had a word for it. It's hygge, pronounced "HOO-gah," a Scandinavian way of life that celebrates coziness, shared meals, and interactions with friends and family. Built around warmth, kinship, and an appreciation for the little things, hygge is a familiar tradition in Denmark, which ranks No. 1 in the latest World Happiness Report. The Danish desire for coziness is spreading to the States, thanks to a slew of books on the topic in 2017.
