Saunagus (derived from the German word meaning "pouring on the oven") is Denmark's own brand of steamy wellness. Tina Andersen, the "gus master" at the Kurhotel Skodsborg, explains that participants start by sitting perfectly still as oil-infused steam is swirled throughout the chamber by a swinging towel. Three short sessions of increasing heat are interspersed with brief breaks outside, culminating in a tingling dip in the sea. If that sounds too hot, try winter bathing. Sea swimming in winter has become a growing trend all over Denmark. According to the country's Council for Greater Water Safety, more than 25,000 Danes regularly crack holes in the subarctic ice for a chilly but refreshing dip. The shocking temperatures are known to have plenty of health benefits, stimulating the secretion of endorphins and quickening the pulse. Regular soaks are thought to reduce stress levels and fatigue, and decrease symptoms of asthma and rheumatism.
