In this episode, the University of Portsmouth's Professor Mike Tipton, a world leader in extreme environmental physiology talks about the effects of cold water and its positive and negative implications for paddlers and water users.

As Mike explains, the negative effects of cold water are well known and well researched, but the positive effects are less so and anecdotal.

We discuss cold water shock and its effects, as well as the positive effect of cold water on mental health and inflammation.

Simon also picks up some tips on keeping his fingers and toes warm on those cold surfing days and Mike shares his claim to fame.
