London-based Helena Smith has been walking on the hygge side of life as a freelance travel writer and photographer for the last 15 years. One of her first assignments was to travel around Denmark, and she still returns regularly to enjoy saunas--alternating with icy lake plunges--healthy smørrebrød, impeccable Scandi design aesthetics and a population that is considered to be the happiest in the world. Helena has written about Copenhagen for Lonely Planet, Rough Guides and Bradt, and she also has her own London food blog, eathackney.com.
