Taking the Plunge: Cold Water Immersion

Season 1

Cold water immersion has many different faces. There’s the cold blast in the shower; ice baths; wild swimming… Which one are you prepared to look in the eye?


Frank is building an ice bath at Jenny’s house – so that he can use it when he’s there. That means he needs to convince his girlfriend of this painful practice’s benefits. Where better to start than on their holiday to the UK, where he can usher her into the North Sea, followed by a dunk in a glacier lagoon in Iceland?

Since the Melbourne lockdowns, Frank has followed a cold water regime, going for winter ocean swims. He also works at Peninsula Hot Springs, so of course he takes full advantage of their ice bath. Professor Marc Cohen is the medical director of the Hot Springs and designed the 'Fire and Ice' feature, so he’s got a lot to say about the therapeutic aspect of this practice and the workings of the sympathetic nervous system. That screaming you hear at the top of the episode? That’s courtesy of the Hot Springs four-degrees ice bath.

Finally, in the middle of winter, Frank meets the Port Melbourne Ice Bergs as they train to swim the heads – which will have them in the ocean for 75 minutes. Somehow, they manage to make their daily endurance feat sound like a really good time.

  • Grief is the Price of Love

    How do we confront the mortality of someone we love? In the final episode of this season of Spirit Levels, our guests help Jenny through her existential fear of Frank’s death (it’s okay, he’s fine). Lo Carmen, host of the podcast Death Is Not the End, talks romantic death pop, funeral song choices and turning ashes into records. Kimba Griffith, of The Last Hurrah Funerals, discusses the fine and varied ways in which you can send off your person. Memoirist Elly Varrenti shares the difficulty in forever being the ‘other woman’ when in a relationship with a widower. Is it a coincidence this episode came about after we visited the Capuchin Catacombs in Sicily and saw all the mummies dressed in their Sunday best, so that their grieving relatives never have to let them go? No. But also, preparing for our own deaths is a vital part of life admin, and something we all need to give proper thought.This will be the last episode from us for a while as we take time out to work on a special season. What a great time to play catch-up with our 28 episodes! Please stay followed and subscribed for those updates.

  • Facing Fears

    What are you afraid of, reasonably or unreasonably? And what can help combat that? Hypnosis? Exposure therapy? Flooding? Guidance? In episode 27 of Spirit Levels we use Jenny’s fear of sharks as a case study, meeting with Will Salter, a man who came eye to eye with a great white shark when surfing; Lola Broomhall, a freediver and breathwork practitioner, and hypnotist Jeremy Walker.LINKSLola Broomhall: breathwork, physio, freediving workshops, professional mermaiding!Hey, if you like the tune that’s playing near the beginning, when Jenny and Frank are talking about fear, that’s ‘Summer of Sad’ by Salty Lips.St Andrews Beach Community Choir sang the ‘Don’t Be Scared of the Ocean’ refrain and are based on the Mornington Peninsula.The Summit AI coach Jenny used (free!)Hypnotist Jeremy WalkerA wonderful story about freediving by Michael Adams in the Australian Review of Books.
  • Optimal Morning Routines

    We’re going to be in Bali by the time you hear this, gathering some more weird wellness intel, so this ep we handed the mic over to our listeners to find out how they start the day the right way. From oil pulling, to 5 Tibetan rites to doing naked squats in the elements… we really feel like we know them very well now. LINKSAmong our contributors this episode were Mena from Human Thriving (who spoke about glucose)...And Katie from Therapeutic Eating (who spoke about objectivity).Spirit Levels on Instagram.Our newsletter.
  • What Would the Stoics Do?

    Who the hell would want to be a Stoic? That was journalist Brigid Delaney’s thought when she was commissioned to write a book on Stoic philosophy. Brigid felt she was more Epicurean by nature if anything, but having now written the book Reasons Not to Worry: How to be Stoic in Chaotic Times, she's happy to admit Marcus Aurelius and co. rule her life.In this episode, Brigid walks us through:What to do when you have FOMO in your career.What to do with feeling of failure.What to do when you piss off your neighbour.What to do when conflicts escalate.How to cope with disaster.How to create structure around your drinking habits.And how to make your own shame vaccine. Jenny reflects on how her thinking was transformed by Stoicism during a stint at Alcoholics Anonymous. Frank insists he’s a Stoic, despite regularly pulling hand guns on tradies.LINKSBrigid Delaney's book Reasons Not to WorryBrigid Delaney's book WellmaniaSpirit Levels on InstagramOur newsletter
  • Life Coach Cults

    If your life coach is a psychopath, is that necessarily a bad thing? Coaching is marketed to wannabes as a luxury, business-class lifestyle that grants you total freedom and easy money. (And oh yeah, you might have to deal with some clients in crisis, too.) You’ve just got to learn how to hustle, which means paying a whoop-load of cash to other coaches to get 'the codes'. Possibly for the rest of your life.This episode, Frank and Jenny revisit their favourite topic, piggybacking off the Netflix UK documentary Psychopath Life Coach.We ask our guest Danielle Ryan – a former life coach who now makes explainer videos dissecting the scammier side of the industry – what trends she’s seeing. These range from the escalating industry of coaches coaching coaches, to the ‘fitness coach to business coach pipeline’, to business coaches rebranding as spiritual coaches.Along the way, Frank and Jenny discuss Matthew McConaughey’s infiltration into coaching, sweat-lodge disaster guy James Arthur Ray, NLP, Landmark and Dale Carnegie. We also get Jenny’s Indonesian language teacher Jamsen on the show, to talk about how life coaches are taking over Bali and his take on whether that’s all bad.By the way, if you dig this episode, you’ll love our eps Make Me a Life Coach and also the episode Energy Healing, Manifesting and The Placebo Effect.LINKSDanielle Ryan on the most common business coaching scams.Danielle Ryan’s videos on NLP, part one and part two.Jenny’s Bahasa teacher, Jamsen.

  • Saunas, Sweat Lodges and Snow Monkeys

    This episode, we invite you to let it all hang out. Frank and Jenny visit the Finnish Church in London to take a pew in the basement sauna that brings everyone together, not just the congregation. There, rector Marjaana Härkönen talks about the connection between spirit and the sauna – ‘löyly’ – and what to drink while you’re busy connecting.Now look, we know people banging on about saunas can be as annoying as people banging on about ice baths (hey – we’ve got an episode on that, too!), but when integrative wellness professor Marc Cohen told us the full gamut of what these sweat boxes can do for our meat vessels, we were genuinely surprised.Always one to look at the worst-case scenario, Jenny recounts the grizzly deaths that occurred at the 2010 World Sauna Championships, and in sweat lodges such as that of one-time Oprah mascot James Arthur Ray. But surely she can see the logic in preparing for the worst (her favourite thing to do) by engaging in hormesis – the act of adapting to stress, such as extreme heat, and thus better preparing for future stresses. Frank’s a lucky fella. He works at Peninsula Hot Springs, so he gets to have a sneaky sauna and ice bath combo every day. To make it up to Jenny, he’s built a grand stone and wood sauna at her place, together with an ice bath in a converted chest freezer.PS: If you liked this episode, you'll love our sixth episode, Taking the Plunge: Cold Water Immersion.LINKSWellness professor, Dr Marc Cohen Finnish Church in LondonLeave us a voice message for a future episode on SpeakpipeSpirit Levels on InstagramOur newsletter
