In a new interview titled "Infrared – THIS IS INCREDIBLE! How Infrared Light Works! Interview with Johannes Kettelhodt," health expert Patric Heizmann speaks with wellness expert for infrared technology, Johannes Kettelhodt (née Heirate Jeß). Together, they explore what infrared actually is, why the topic is often misunderstood, and how red light and near-infrared are used by athletes, biohackers, and health-conscious individuals as part of modern recovery and well-being routines.

In the conversation (also published as an audio episode of "schlank + gesund mit Patric Heizmann"), Heizmann describes infrared as a missing puzzle piece in the "modern indoor lifestyle" – a world where many people spend the brightest hours of the day indoors and rely heavily on artificial light. Kettelhodt adopts a practical, scientifically interested approach and emphasizes that infrared is not "hocus pocus." He refers to the considerable amount of research on the topic but keeps expectations realistic: it is not a cure for diseases but a technology that can support overall well-being when consciously integrated into daily life.

Topics of the Interview:

  • Infrared Basics: Where infrared is located in the light spectrum and why discussions are often unclear when UV light, visible light, and infrared are mixed.

  • Relevance in Modern Times: The modern reality with screens, indoor work, and low-light seasons – and why more and more people are looking for "light routines" for home.

  • Device Check: The differences between small, targeted lamps and larger panels, and how to design a realistic routine for home use.

  • Target Groups: From performance-oriented athletes to beginners looking for a simple, repeatable ritual.

Why the Topic is Receiving So Much Attention 

Red light and infrared applications have moved from niche wellness circles into the mainstream. The interview clarifies the "why":
More and more people are looking for home solutions that can be easily and time-efficiently integrated into daily life – as a complement to training, stress management, and sleep hygiene, not as a substitute for them.
