What are the real differences between evaporative, phase-changing, electronic, and ice-based cooling vests? Why are athletes, firefighters, and even lab workers turning to these technologies?

"Lean more about Nahtlos Duratrode electrodes at https://www.nahtlos.com/"

In this episode, Dr. Olli Tikkanen speaks with José Näf, co-founder of Duracool, to break down the science and real-life applications behind different cooling vest technologies. As global temperatures rise and performance demands increase, understanding these cooling systems becomes crucial in both sports and professional settings.

José explains the four main cooling vest technologies: evaporative, phase-changing materials, electronic cooling with fans, and traditional ice-based solutions. He highlights where each method fits best—from professional sports to protective lab gear—and discusses why evaporative cooling mimics the natural human sweating process, especially useful for those who cannot sweat. They also explore the scientific controversy around the post-exercise use of ice baths, and the true nature of "phase change" in cooling materials.

This is a quick but informative episode for researchers, athletes, and professionals interested in how technology helps regulate body temperature under extreme conditions.

This is the second part of our conversation with Dr Darryn Stamp where we explore  complexities of athlete transitions within professional football. The conversation moves to exploring embodiment and relationship with sport post-retirement. Why is it that some elite and professional athletes have little interest in sport and exercise after their retirement?

Dr. Darryn Stamp played professional football before transitioning his second career as an academic. He wrote his PhD thesis at the University of Hull with a focus on the contextual complexities of transitions through and out of professional football.

Darryn is currently the Deputy Head of School for Health, Education and Sport at University Campus North Lincolnshire.

Today’s episode continues explorations of the complexities of athlete transitions within professional football. Career transitions often present a challenge to an athlete's identity and change their position in their relational networks. While career transitions have been an established topic in sport psychology, they are still underexplored from a sociological perspective, which informs our conversation today.
