Helen takes an 11-degree chilly dip in Windermere in the Lake District with renowned Cold Water Swim Coach Gilly McArthur to experience the benefits of cold exposure and blue spaces.

Gilly is part of a world-class team working on an NHS research project with Oxford and Portsmouth Universities, investigating whether cold water & outdoor swimming can help alleviate anxiety and depression.

Gilly explains the compelling science behind how the cold improves our physical and mental wellbeing, what it does to our brains and bodies, and how nature and ice-swimming has helped her through some painful times.
