Heavy Metal Detox & Heart Health

Heavy metal exposure is part of modern life. From environmental pollution and food sources to dental work and everyday household products, many of us carry a higher toxic load than we realise. The question isn’t whether toxins exist — it’s how the body safely and naturally deals with them.

In this short video, Sunlighten Co-Founder Connie Zack explains the science behind one of the most talked-about benefits of infrared sauna use: detoxification through sweating, including the elimination of certain heavy metals.

Drawing on both personal experience and clinical research, Connie explores why sweat is more than just temperature regulation. Studies have shown that sweating can help remove toxic elements — including heavy metals such as mercury and cadmium — sometimes in greater concentrations than those found in blood or urine. This insight has reshaped how infrared sauna therapy is viewed in both wellness and clinical settings.

The video also covers another key benefit of infrared sauna use: heart health. Connie explains how infrared heat increases circulation and creates a “passive cardio” effect, supporting cardiovascular function without physical exertion. Sunlighten’s clinical trial demonstrated measurable improvements, including reductions in blood pressure, helping to establish infrared sauna therapy as a legitimate tool for long-term wellbeing.
