This guide provides wisdom from the Nordics, a region long known for its healthy and progressive lifestyle.

The Danes may have their Hygge and the Norwegians their back to the land books, but the Swedes have a 'sundhet', more or less translated to 'soundness', a balanced, even keeled approach to a life of moderation. In general, Swedes are very healthy when it comes to food and exercise, and part of the key to this 'soundness' is that nothing is done at its extreme. Everything is incorporated over time and in steps into work and family life so as to make it manageable and sustainable.
