In this live episode recorded at the Happy Place Festival, Fearne Cotton talks with Dan Cray and Dr Paul Anastasiades, the co-founders of the UK-based hydration brand Phizz. They discuss the biological and neurological consequences of dehydration, explaining how even mild water loss impairs the brain, thickens the blood, and triggers the stress hormone cortisol. The guest explains how his background as a neuroscientist recording from neurons in a lab helped shape the formula, which combines water, electrolytes, and a precise amount of sugar to maximize absorption. The conversation explores the intersection of physical hydration and mental well-being, while sharing candid stories about the realities of scaling a business.
Host welcomes listeners and introduces the Happy Place Festival and the FIZ sponsors.
Dan and Paul introduce themselves and describe how FIZ was created to fill a hydration gap.
Paul details the neuroscience and chemistry that underpin the tablet’s design and benefits.
Explores how electrolytes and glucose work together to efficiently hydrate the body.
Dan and Paul recount their decade‑long journey from startup to UK’s top hydration brand, including challenges and milestones.
Discusses how adequate hydration supports mucosal membranes and reduces illness risk during colder months.
Both founders share practical tips for staying hydrated amid busy schedules and personal experiences.
Hosts wrap up, share personal hydration commitments, and thank the guests and festival attendees.
The guest explains that although the brain makes up only two percent of body weight, it consumes about twenty percent of daily energy due to electrical activity.
Cortisol Spike From Dehydrationinsight
Studies show that people who are habitually dehydrated experience a much higher spike in the stress hormone cortisol when exposed to stressful situations.
Biological Battery Effectinsight
Cells maintain electrochemical gradients of sodium and potassium, acting essentially as biological batteries that harness electricity for vital bodily functions.
Sugar Free Limitationsstrategy
The guest argues that sugar free rehydration formulas are inefficient because they miss out on the sodium glucose co-transporter mechanism that drives fast water absorption.
Blood Test Dehydration Mishapstory
The co-founder shares a personal anecdote of failing a medical blood test because he was severely dehydrated on a busy workday, leaving the phlebotomist unable to find a vein.
“make such a difference to our energy and focus and honestly, our personalities.”
“So your brain weighs about 2% of your entire body weight, but it uses about 20% of the energy that you'll use over the course of a day.”
“So the, one of the things that happens is your cells will kind of shrink up, right?”
“You can actually drink too much water. So just as dehydration is a state where you have too little water in your body, there's another, the term is hyperhydration, which means that you have too much water in your body.”
You know how your mood dips when you’re hangry? Well, being thangry is a thing too! Thirst – being dehydrated – can have a very real impact on everything from your stress levels to cognitive function and physical performance. We’re heading back to this year’s Happy Place Festival, where the Talk Stage was sponsored by Phizz, the UK’s number-one selling hydration brand. In this chat with Fearne, Dan Cray, CEO and Co-Founder of Phizz, and Dr Paul Anastasiades, Head of Product Development and Co-Founder, explore what hydration really means, why it’s so easy to overlook, and how getting it right can help us feel more energised, focused and more like ourselves. They also explain why effective hydration isn’t just about drinking more water, but about getting the right balance of electrolytes and nutrients to help your body perform at its best. Plus, how much water should you actually be drinking each day? Hosted on Acast. See acast.com/privacy https://acast.com/privacy for more information.
