Catching A Whiff Of Open Water Swimming
Open water swimmers know about the fumes from an escort boat or the stench of pollution in the water. They wrinkle their nose and try to avoid breathing in the foul air. If the boat exhaust is too much, they end of coughing and gagging.
But the Solfatara volcanic crater at Pozzuoli near Naples in Italy emits sulphurous fumes. The fumes contain hydrogen sulphide, a poisonous gas that smells like rotten eggs. But in small amounts, the hydrogen sulphide is not overwhelming while it also increases blood flow.
Which can help lead to a more healthful lifestyle.
