In this episode, Dr. Olli Tikkanen and José Näf explore the life-saving potential of evaporative cooling vests in extreme environments, including the Hajj pilgrimage, where temperatures can exceed 50°C. José discusses the development of seam-free cooling garments that comply with religious dress codes, offering relief for thousands of elderly pilgrims walking long distances in dry, desert climates.

The conversation also covers the role of cooling vests in protecting older adults in Southern Europe during heat waves and how humidity levels affect the performance of evaporation-based cooling. José outlines exciting product development on the horizon, including new designs for head and neck cooling and integrating airflow with evaporation for stronger effects—all without electronics.

This episode highlights the future of wearable cooling technology and its role in protecting vulnerable populations under rising global temperatures.
