From Wikipedia: One of the fundamental aspects of Danish culture is "hygge", which, although translated as "coziness" is more akin to "tranquility". Hygge is a complete absence of anything annoying, irritating, or emotionally overwhelming, and the presence of and pleasure from comforting, gentle, and soothing things. Hygge is often associated with family and close friends. Christmas time when loved ones sit close together with candles lit on a cold rainy night is "hygge", as is grilling a pølse (Danish sausage) on a long summer evening.
Professor Judith Friedman Hansen, in The Proxemics of Danish Daily Life, tells us that "familiarity is the key element, a closed-in state of stable predictableness associated with small-scale gatherings of people". This means creating a hyggekrog - a protective space characterized by low tables under a subdued light, with candles, flowers, food, and drink.
