Water Therapy

I'm after something that mimics the reviving sensation of paddling in cold sea - that wonderful shock you get when you dip your toes into the water and it laps back and hits your ankles. As I'm currently too far away from any coast I'm going to plunge my feet into a bucket of cold water.  And then I'm just going to sit. I will do this not now - but tomorrow afternoon at around 3.30pm.
