27: Water Purifiers - That's Quite A Thirst with Dr Will Duffin
10/26/22 • 37 min
Cathy and Wayne are joined once again by World Extreme Medicine Joint Medical Director Dr Will Duffin as they tackle the murky world of water purification and how to keep healthy in the wilderness.
Learn the difference between filtration and purification, understand the different types available and why there are so many, how to choose your water source, why it's not just drinking water that needs to be pure, why you should consider carrying a form of filtration to use in the UK and how you can get clean water to drink without spending any money at all!
Not necessarily a podcast to listen to while you are eating; there is lots of discussion about "travellers tummy", the curious ability of a sheep to die in a water source, how drinking your own sweat can get you out of a sticky situation and, in the type of magnificent random deviation that you can only experience on Outdoor Gear Chat: a rather terrifying description of how easy it is to die in your own tent.
A note on using chlorine tablets during pregnancy:
"As a general rule it appears most chlorine-based products are considered ‘safe' if used at recommended concentrations. Having said this, as with all medicines in pregnancy, there is very limited good quality evidence and uncertainty remains. It’s important that the risk of harm from chemical treatment is balanced with the risks of water borne diseases in pregnancy. In my view, whilst chlorine-based products are probably ok, filtration and boiling should be preferred options while we await more definitive answers from the scientific literature. Always refer to manufacturer's instructions." Dr Will Duffin

26: Kit Lists - Expeditions with Andy Cave
Climber, Alpinist, Himalayan Mountaineer, International Mountain Guide, and Award Winning Author Andy Cave joins Cathy and Wayne to talk about life before Gore-Tex, ye olde plastic boots, fibre glass ice axes, layering, sweat management, why feathers are fab, glove choices, harness culture (yes, it is a thing!), why paying extra for a dry treated rope is well worth it and just when is it okay to use modern ultralight running kit in the mountains.
Learn about layering in action, what to think about when buying kit and, in what is possibly THE most spectacular random deviation of the series ever: the marvels of victorian engineering which run underground between Thirlmere in the Lake District and Manchester.
Andy is part of the Rab sponsored athlete team and has a huge experience of using their full range while pushing climbing to the limit on bold new routes in the Alps, Alaska, Patagonia and the Himalaya. He also hosts Rab's podcasts: The Mountain People Podcast - Rab® UK
