"Lean more about Nahtlos Duratrode electrodes at https://www.nahtlos.com/"
In this episode, Dr. Olli Tikkanen and José Näf discuss how evaporative cooling vests support individuals who suffer from heat sensitivity due to medical conditions such as paraplegia, multiple sclerosis, and severe burns. José explains how the loss of sweating ability in these groups can lead to dangerous heat stress and why conventional cooling methods, like ice packs, are not always safe or effective. They also explore the performance of evaporative vests in various humidity levels, with ongoing studies assessing use in places like Dubai and Thailand. From construction sites to clinical recovery, this episode highlights where and how cooling vests are used, including guidelines for wear time and practical use in daily routines. José also shares insights from collaborations with rehabilitation institutions and new testing efforts with artificial skin patients. This conversation offers a rich look into the physiological needs behind cooling innovation and its direct impact on people’s quality of life.

How does an evaporative cooling vest keep your skin up to 5°C cooler for hours—without making you wet? José Näf shares how smart materials can transform temperature regulation.
"Lean more about Nahtlos Duratrode electrodes at https://www.nahtlos.com/"
In this episode, Dr. Olli Tikkanen continues the conversation with José Näf, co-founder of Duracool, focusing on the design, functionality, and physiological impact of evaporative cooling vests. These vests use semi-permeable membranes to gradually release water vapor, providing long-lasting cooling without soaking the user.
José explains the technical design of their shoulder pads and vests, their application in both occupational settings and for individuals with medical conditions such as artificial menopause, and the importance of wearing them over—not under—clothing. Laboratory tests show their cooling performance lasts significantly longer than sponge-based vests, making them ideal for situations with moderate movement, like construction or low-intensity work in hot environments.
This episode is a must-listen for professionals and researchers interested in thermal comfort and performance under heat stress.

/Highlights/ Cool Science: How Cooling Vests Work & When to Use Them – José Näf (Pt1)
Wednesday Feb 04, 2026
Wednesday Feb 04, 2026
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.

In the latest episode of the podcast hosted by Dr. Olli Tikkanen, listeners are treated to an insightful conversation with the distinguished Professor James F. Sallis. Professor Sallis, recently appointed to the Department of Family Medicine and Public Health at the University of California, San Diego, is a renowned figure in the realm of behavioral medicine and public health. With a rich career marked by his dedication to understanding the intersections of physical activity, built environments, and public health, Professor Sallis has been recognized globally for his pioneering research. Notably, he has been identified as one of the world's most cited authors in the social sciences and has received accolades such as the Lifetime Achievement Award from the President's Council on Fitness, Sports, and Nutrition.
In this episode, Dr. Tikkanen and Professor Sallis delve deep into the evolution of physical activity research over the years. They discuss the role of built environments, the significance of accurate measures, and share insights into the challenges and opportunities in the field. Professor Sallis recounts the transformative shifts he has witnessed in the domain of behavioral nutrition and physical activity. He emphasizes the myriad benefits of physical activity, from its role in bolstering the immune system to its anti-inflammatory impacts. However, he also highlights the challenges in translating research into policy and practice, lamenting the lack of dedicated infrastructure and funding for physical activity in public health.
The conversation also touches upon the broader implications of physical activity on public health, especially in the context of the COVID-19 pandemic. Professor Sallis underscores the importance of physical activity in combating infectious diseases and its potential role in mitigating severe outcomes in COVID-19 patients. The episode concludes with a discussion on the complexities of promoting physical activity, given the powerful industries that inadvertently promote sedentary lifestyles. From the oil companies to the electronics sector, these industries pose significant challenges to the mission of re-engineering physical activity back into our daily lives.
Tune in to this enlightening episode to gain a deeper understanding of the multifaceted world of physical activity research and its profound implications for public health.
