SUPPORT YOUR HEART WITH INFRARED

Dr. Joel Kahn's Heart Health Ritual

Why Dr. Kahn Loves Sunlighten

"Foundational heart health is built through daily habits that support circulation and vascular function. Regular infrared sauna use safely elevates heart rate and blood flow, creating a cardiovascular response similar to moderate exercise. I have used Sunlighten for years because of their commitment to quality infrared technology and safety, making sauna therapy a practical, reliable tool for long-term heart health."

–– Joel Kahn, MD

Follow Dr. Kahn's sauna protocol

  • Before you sauna

    Hydrate well to support circulation and maintain healthy blood pressure during heat exposure.

    30–40 minutes, 4–5 times per week. Sauna use increases heart rate and blood flow, creating a cardiovascular response similar to moderate exercise, which supports vascular flexibility and heart function.

  • After you sauna

    Rehydrate and rest briefly to allow heart rate and blood pressure to normalize, supporting cardiovascular recovery.

  • Habit to stack

    Slow, rhythmic breathing to further enhance circulation and calm the cardiovascular system.
